If a line has a slope of 4 and goes through the point open parentheses short dash 1 comma 1 close parentheses, then the equation for the line in slope-intercept form is ______________.
a.)
y equals short dash 4 x minus 3
b.)
y equals 4 x plus 3
c.)
y equals 4 x plus 5
d.)
y equals short dash 4 x minus 5
Answers
You are given the slope = 4 and a point is (-1,1)
The equation of a line is written as y - mx + b where m is the slope and b is the y intercept
Using the slope you now have y = 4x + b
Solve for b by replacing x and y with the values of the point:
1 = 4(-1) + b
Simplify:
1 = -4 + b
Add 4 to both sides:
b = 5
The equation of the line is C.) y = 4x + 5

Jimmy Page puts $30 into a savings account that promises 1% interest
compounded quarterly. Which formula would you use to determine the
account balance in 25 years?
Answers
In 25 years the account balance will be $38.51 if Jimmy Page puts $30 into a savings account that promises 1% interest compounded quarterly.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
P = $30
r = 1% = 0.01
n = 4
[tex]\rm A = 30(1+\dfrac{0.01}{4})^{4\times25}[/tex]
After calculating:
A = $38.51
Thus, in 25 years the account balance will be $38.51 if Jimmy Page puts $30 into a savings account that promises 1% interest compounded quarterly.

Consider the line 4x-8y= -6.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line
Answers
Answer:
Perpendicular slope = -2Parallel slope = 1/2======================================================
Explanation:
Let's solve for y to get the equation into y = mx+b form, aka slope intercept form.
4x-8y= -6
-8y= -6-4x
y = (-6-4x)/(-8)
y = -6/(-8) + (-4x)/(-8)
y = 3/4 + (1/2)x
y = (1/2)x + 3/4
This is now in y = mx+b form
m = 1/2 = slope
b = 3/4 = y intercept
We'll ignore the y intercept and focus on the slope only.
-----------------
Rule: If the slope of a line is a/b, then the perpendicular slope is -b/a
Flip the fraction and flip the sign.
In this case, the original slope 1/2 has a perpendicular slope of -2/1 or simply -2.
The original slope multiplied with the perpendicular slope yields -1. So (1/2)*(-2/1) = -1
-----------------
Another rule: Two parallel lines always have equal slopes, but different y intercepts.
The original slope is 1/2, so the parallel slope is also 1/2.

The sigma notation means to find the sum of the given geometric series where the first term is when n = 1 and the last term is when n = ∞.
To find the first term in the series, substitute n = 1 into the expression:
[tex]\implies a_1=4^{-1}=\dfrac{1}{4}[/tex]
The common ratio of the geometric series can be found by dividing one term by the previous term:
[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{4^{-2}}{4^{-1}}=\dfrac{1}{4}[/tex]
As | r | < 1 the series is convergent.
When a series is convergent, we can find its sum to infinity (the limit of the series).
Sum to infinity formula:
[tex]S_{\infty}=\dfrac{a}{1-r}[/tex]
where:
a is the first term in the seriesr is the common ratioSubstitute the found values of a and r into the formula:

Suppose there is a big drop in interest rates in Mexico and a small drop in U.S. interest rates. Everything else equal, what is likely to happen to value of the MXN?
Answers
If we suppose that there is a big drop in the interest rates in Mexico and a small drop in the interest rates in the U.S.A, with everything else equal, the value of MXN will decrease.
The foreign exchange market works according to the principles of firms, households, and investors:
These three constituent factors of the foreign exchange market determine the demand and supply patterns in the market. Demand for a foreign currency might increase in the foreign exchange market is linked to the expectation of an increase in the value of a foreign currency. Supply of a foreign currency in the foreign exchange market is linked to an inverse principle, where the expectation of a decrease in the value of foreign currency pushes supply upwards. If we are to suppose that there is a big drop in the interest rates in Mexico and a small drop in the interest rates in the U.S.A., then the value of the MXN will decrease, with everything being equal. A higher interest rate leads to the appreciation of a foreign currency relative to other currencies in the foreign exchange market. A lower interest rate leads to the depreciation of a foreign currency relative to other currencies in the foreign exchange market.Therefore, if we suppose that there is a big drop in the interest rates in Mexico and a small drop in the interest rates in the U.S.A, with everything else equal, the value of MXN will decrease.

What is Function?The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
A. Since x-intercepts indicate the amount of each bacteria at the start of the experiment, there was more of bacteria B than bacteria A at the start.
False, it is the y-intercept of the function that indicates the amount at the start of the experiment.
B. Since y-intercepts indicate the amount of each bacteria at the start of the experiment, there was more of bacteria B than bacteria A at the start.
True, the y-intercept is given when x = 0, indicating the initial value of the function.
C. Since the maximum value in the table for bacteria A is greater than the maximum value in the table for bacteria B, bacteria A has a faster growth rate than bacteria B.
False, because the maximum value of each table is given in different times, and also the initial value of each table is different.
D. Since the minimum value in the table for bacteria A is less than the minimum value in the table for bacteria B, bacteria A has a slower growth rate than bacteria B.
False, the growth rate is not given by the initial value. If we model both tables with an exponential function, the count of bacteria A quadruped in two days, and the count of bacteria B doubled in one day, so they have the same growth rate.

Given that:-
The equation for free fall at the surface of some planet (s in meters, t in seconds) is s = 2.86t²

THE LENGTH OF A PAINTING OF A TREE IS 2/9 OF THE LENGTH OF THE ACTUAL TREE. IF THE LENGTH OF THE PAINTING OF THE TREE IS 16 INCHES, WHAT IS THE LENGTH IN INCHES OF THE ACTUAL TREE
Answers
The length of the actual tree will be 72 inches.
Fraction is the portion of a total amount where the above part of the fraction is the denominator and the bottom part of the fraction is called the numerator.
The equation whose highest degree of the variable is 1 is called a linear equation.
Here given that the length of a painting of the tree is 2/9 of the actual length of the tree.
So mathematically the length of a painting= (2/9)*the length of actual tree
Let the length of the actual tree is x
then from above it is clear that the length of a painting of the tree= (2/9)x
Given the length of the painting is 16 inches.
So the linear equation will be (2/9)x= 16
⇒ x= 16/(2/9)
⇒x= 16*9/2
⇒x=72 inches
Therefore the length of the actual tree will be 72 inches.

Answers
Answer:
Median is 6
standard deviation is 2.39

the median is the mid number in the data set
The median formula is {(n + 1) ÷ 2}th, where “n” is the number of items in the set and “th” just means the (n)th number.
There are 51 data points in this set (n = 51)
so 51 / 2 = 25.5, the. number in the 25th slot is our median
3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9, 9, 9, 10, 10, 10, 10, 10, 11, 11, 11, 11, 11
the standard deviation is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

the segments ab and cd are graphed on a coordinate plane. The endpoints of ab are at (9,4) and (9,20). CD is parallel to the x-axis, and one of its endpoints is at (5,8). if ab=cd and cd is entirely in the first quadrant, what is the other endpoint of cd
Answers
Answer:
21, 8
Step-by-step explanation:
The second endpoint is of the form (X, 8) since it's parallel to the x axis.
Given the congruence of the two segments, we can tell that its length is 16 units (since [tex]|4-20| = |-16|= 16[/tex])
At this point the two possible endpoints for the segment are [tex](5-16; 8)[/tex] or [tex](5+16, 8)[/tex]. The fact that the segment has to sit in the first quadrant rules out the first option (it's endpoint will be at (-11, 8) which will set most of it in the second quadrant) and we're left with (21, 8)
