Answer:
y=-4/3 + 2
Step-by-step explanation:
So first we need to find the slope which is rise over run or rise/run. We already know the slope is negative because it is slanted to the left \.
The equation should be in this form y = mx+ b
m = slope
b = y- intercept
The slope is -4/3
The y-intercept is 2
y= -4/3 + 2

4x+1+3=8 ayuden manden paso a paso
Answer:
x = 1
Step-by-step explanation:
Solve for x:
4 x + 1 + 3 = 8
Hint: | Group like terms in 4 x + 1 + 3.
Grouping like terms, 4 x + 1 + 3 = 4 x + (1 + 3):
4 x + (1 + 3) = 8
Hint: | Evaluate 1 + 3.
1 + 3 = 4:
4 x + 4 = 8
Hint: | Isolate terms with x to the left hand side.
Subtract 4 from both sides:
4 x + (4 - 4) = 8 - 4
Hint: | Look for the difference of two identical terms.
4 - 4 = 0:
4 x = 8 - 4
Hint: | Evaluate 8 - 4.
8 - 4 = 4:
4 x = 4
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 4 x = 4 by 4:
(4 x)/4 = 4/4
Hint: | Any nonzero number divided by itself is one.
4/4 = 1:
x = 4/4
Hint: | Any nonzero number divided by itself is one.
4/4 = 1:

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle:
A(5,5), B(7,5), C(7,-1), and D(5, -1).
Given these coordinates, what is the length of side BC of this rectangle?
units
Answer:
The length of the side BC is 6 units
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We need to calculate the distance between B(7,5) and C(7,-1):
[tex]d=\sqrt{(7-7)^2+(5+1)^2}[/tex]
[tex]d=\sqrt{36}[/tex]
d=6
The length of the side BC is 6 units

Answer: 20%
Step-by-step explanation:
We have to find out how many prime numbers there are from 20 to 30.
There are only 23 and 29. We have to make a fraction out of 2 over 10.
The fraction can be: [tex]\frac{2}{10}[/tex]
[tex]\frac{2}{10}[/tex] can be written as a percent as 20%.

distance be tween (5,-8) and (5,2) on the coordinate plane
Answer:
10 is the distance
Step-by-step explanation:
d = square root (x2-x1)^2 + (y2-y1)^2
(5-5)^2 = 0
(2-(-8))^2 = 100
0 + 100 = 100
square root 100 = 10
Maya claims that 8n is the number of dots in figure n. Kiana claims that the number of dots in figure n is given by 4(n+1)
Consider the square arrangements below in relation to the girls' expressions, where n represents the figure number.
Determine whether Maya, Kiana or both girls are correct in their given expressions. Justify your response.
The evaluation of your response will be based on the following criteria.
Answer:
Answer:
Kaya's answer is correct.
Step-by-step explanation:
The number of dots in successive figures are
8, 16, 24.
So Kaya's solution 8n is correct.
When n = 1, first square = 8*1 = 8 dots
n = 2: second square = 8*2 = 16
n = 3, 3rd square = 8*3 = 24.
If I have interpreted Kianna's formula correctly
for n = 1, then the number of dots = 2(1+ 1)^2 - 2(1 - - 1)^2
= 0.

Internet Usage The number of hours people in the United States
spent using the Internet each year from 1998 to 2001 can be
modeled by the function f(x) 5 26.4x 1 54.4 where x is the number
of years since 1998.
a. Graph the function and identify its domain and range.
b. Find the number of hours that people spent on the Internet
in 2000. Explain how you found your answer.
c. When did people spend about 120 hours per year on the
Internet? Explain how you found your answer.
Answer:
Look in picture
Step-by-step explanation:
Functions can be represented on graph and as equation.
The domain and the range of the function are [0,3] and [54.4,133.6]The number of hours spent in 2000 is 107.2People spend about 120 hours per year in 2001The function is given as:
[tex]f(x) = 26.4x + 54.4[/tex]
(a) The graph, domain and range
See attachment for the graph of [tex]f(x) = 26.4x + 54.4[/tex]
The function represents years from 1998 to 2001.
This means that:
[tex]x = 0[/tex] in 1998 and [tex]x =3[/tex] in 2001
So, the domain is: [tex][0, 3][/tex]
From the graph;
[tex]x = 0 \to f(x) = 54.4[/tex]
[tex]x = 3 \to f(x) = 133.6[/tex]
So, the range is [tex][54.4,133.6][/tex]
(b) Number of hours spent in 2000
First, we calculate x.
[tex]x = 2000 - 1998[/tex]
[tex]x =2[/tex] i.e. 2 years since 1998
So, we have:
[tex]f(x) = 26.4x + 54.4[/tex]
[tex]f(2) =26.4 \times 2 + 54.4[/tex]
[tex]f(2) =107.2[/tex]
(c) When people starts to spend 120 hours.
We have:
[tex]f(x) = 26.4x + 54.4[/tex]
Substitute 120 for f(x)
[tex]120 = 26.4x + 54.4[/tex]
Collect like terms
[tex]26.4x = 120 - 54.4[/tex]
[tex]26.4x = 65.6[/tex]
Solve for x
[tex]x = \frac{65.6}{26.4}[/tex]
[tex]x = 2.48[/tex]
Round 2.48 to the smallest integer greater than 2.48
[tex]x = 3[/tex]
This represents the number of years, since 1998.
So, the actual year is:
[tex]Year =1998 + 3[/tex]
[tex]Year = 2001[/tex]
Hence, people spend about 120 hours per year in 2001

Write sec 325° in terms of the secant of'a positive acute angle.
Answer:
sec35°
Step-by-step explanation:
sec325° = sec(360 - 325)° = sec35°
The secant of a positive acute angle of sec 325° = sec 35° = 1.22077
What are Trigonometric Ratios?
Trigonometry values are all about the study of standard angles for a given triangle with respect to trigonometric ratios.The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given data ,
The trigonometric ratio is = sec 325°
Now , to express the ratio in terms of a positive acute angle , we take the four quadrants of the graph and express the angle in the first quadrant.
And , 325° lies on the 4th Quadrant , where all cosines and secants are positive.
Therefore , sec 325° = sec ( 360° - 35° )
= sec ( 35° )
=1.22077
Hence , the secant of a positive acute angle of sec 325° = sec 35° = 1.22077

You go to the store and notice the people standing in line. 7 adults and 4 children. If this ratio stays the same and there 55 people in the store. how many would be children?
Answer:
20
Step-by-step explanation:
7+4=11
11*5= 55
4*5=20 :)
The number of children and adults will be 35 and 20, respectively.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
You go into the store and observe the folks in queue. There are 7 adults and 4 children. If this ratio remains constant and there are 55 people in the store.
7x / 4x = constant
Then the equation is given below.
7x + 4x = 55
11x = 55
x = 11
Then the number of adults is given as,
7x = 7 (5) = 35
Then the number of children is given as,
4x = 4 (5) = 20
The number of children and adults will be 35 and 20, respectively.

Write a rule that would allow you to test whether (x,y) is on line ℓ.
Answer:
We have a line L.
Remember that in two dimensions, we can write a line as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
And then using one of these points, we can find the value of b.
Then wen we got the equation for the line:
y = a*x + b
We can input a point (x, y)
And see if the equality is true, then the point belongs to the line L.
what is the slope of the line in the graph?
Answer:
1
Step-by-step explanation:
The slope of a line equals rise/run. That is the distance and height between each point. The horizontal and vertical distances are both 1, so 1/1= 1
