Which is the correct ordered pair for point F on the graph?
(–5, –5)
(0, –5)
(–5, 0)
(–5, 5)
Answer:
(–5, 5)
Step-by-step explanation:
Start with the x-axis (left and right).
-5 so you go to the left by 5 steps.
Next is y-axis (up and down).
Without moving your spot in -5, you move up by 5 steps.
That is point F.
Tip: (x-axis, y-axis) or (left/right, up/down)
Negative number: Left or Down
Positive number: Right or Up

Answer:
[tex]y - x = 2[/tex]
Step-by-step explanation:
Given
Points (-2,0) and (-3,-1)
Required
Equation of Line
The first step is to determine the slope of the line; using the following formula
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]Where\ (x_1,y_1) = (-2,0)\ and\ (x_2,y_2) = (-3,-1)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{-1 -0}{-3 - (-2)}[/tex]
[tex]m = \frac{-1}{-3 +2}[/tex]
[tex]m = \frac{-1}{-1}[/tex]
[tex]m = 1[/tex]
The next is to determine the equation of the line using any of the points
The formula is as thus;
[tex]m = \frac{y - y_1}{x - x_1}\ or\ m = \frac{y - y_2}{x - x_2}[/tex]
Using [tex]m = \frac{y - y_1}{x - x_1}[/tex]
[tex]Where\ (x_1,y_1) = (-2,0)\ and\ m =1[/tex]
[tex]1 = \frac{y-0}{x - (-2)}[/tex]
[tex]1 = \frac{y-0}{x +2}[/tex]
[tex]1 = \frac{y}{x +2}[/tex]
Multiply both sides by x + 2
[tex](x+2)*1 = \frac{y}{x +2} * (x+2)[/tex]
[tex](x+2)*1 = y[/tex]
[tex]x+2 = y[/tex]
[tex]y = x + 2[/tex]
Subtract x from both sides
[tex]y - x = x - x +2[/tex]
[tex]y - x = 2[/tex]
Hence, the equation of the line in standard form is [tex]y - x = 2[/tex]
As the result of experimental work, a student finds the density of a liquid to be 0.1369 g/㎤. The known density of that liquid is 0.1478 g/㎤. What is the percent error of this student's work? (Round final answer to the nearest tenth if necessary
Answer:
Percent error is [tex]7.4\%[/tex]
Step-by-step explanation:
Given:
As per the result of experimental work, density of a liquid is 0.1369 g/㎤
Known density of the liquid is 0.1478 g/㎤
To find: percent error
Solution:
The density of a substance is defined as mass per unit volume.
S.I. unit is Kilogram per cubic metre.
Error = Actual density - density as per the experiment = [tex]0.1478-0.1369=1.0109\,\,g/cm^3[/tex]
Percent error = ( error/Actual error ) × 100 = [tex]\frac{0.0109}{0.1478}\times 100=7.4\%[/tex]

Which of the following statements is TRUE about minor central angles?
a.) The measure of the central angle is less than 180°.
b.) The measure of the central angle is equal to 360°.
c.) The measure of the central angle is equal to 180°.
d.) The measure of the central angle is greater than 270°.
Answer
b.) The measure of the central angle is equal to 360°.
Step-by-step explanation:
The car is moving on a rough road with a constant velocity. Hence, its acceleration is zero. As per Newton 's second law of motion, no net force is acting on ...
The true statement is The measure of the central angle is less than 180°.
The correct option is (A)
What is an angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
If the central angle is less than 180 degrees then the sector is known as a minor sector.
The definition of the minor sector also says that "the central angles of a minor sector is less than 180"
Hence, The central angle of a minor sector is less than 180° is true.

Given: f(x) = x² and g(x) = x + 1, find g[f(-2)].
A. -3
B. 1
C. 5
Answer: C
Step-by-step explanation:
f(x) = x² and g(x) = x + 1
This is composite function, i.e function of a function
g(f(x)) = g(x²), since f(x) = x²
f(-2) = (-2)² = 4
g(f(-2)) = g(4) = 4 + 1 = 5

Step-by-step explanation:
Gino paid $3.23 for two tubes of toothpaste. He paid the regular price of $1.79 for one tube. However, he bough the other one for less because he used a discount coupon. How much was the coupon worth?
Answer:
Step-by-step explanation:
Cost of two tubes = $ 3.23
Regular price of one tube = $ 1.79
so, the cost of other tube = 3.23 - 1.79 = $ 1.44
Discount = 1.79 - 1.44 = $ 0.35

Answer:
Step-by-step explanation:
Solve the given 3x + 5y = 2 for y. This will automatically indicate the slope of the line.
Subtracting 3x from both sides of this equation, we get:
5y = -3x = -3x + 2.
Dividing both sides by 5 yields y = (-3/5)x + 2/5.
The slope of the given line is -3/5. The y-intercept of this line is (0, 2/5).

in the following triangle theta=60.Find the values of the angles of the angles B and B'
Answer:
A. B = 64.13° or B' = 115.87°
Step-by-step explanation:
The given angle is opposite the shortest of the given sides, so there are two possible solutions using the Law of Sines. Either way, we have ...
sin(B)/16 = sin(θ)/15.4
B = arcsin(16/15.4·sin(60°)) ≈ arcsin(0.899767)
B = 64.13° or B' = 180° -64.13° = 115.87°
Mary was told that a line goes through the points (1, 3) and (6, -2) and has a slope of 3. A. Explain why the information Mary was given cannot be correct. B. If the given point (1, 3) and the given slope are correct, what is the equation for the line? C. Give the coordinates of another point on the line. D. If the given points are correct on the line, what is the slope? E. Write an equation for the line.
Answer:
Below in bold.
Step-by-step explanation:
A. We can calculate the slope using (y2 - y1) / (x2 - x1)
= (3 - (-2)) / (1 - 6)
= 5/-5
= -1.
So the given slope of 3 or one of the points is NOT correct.
B. If the point (1, 3 ) and the slope are correct then the equation for the line (using the point-slope form) is y - 3 = 3(x - 1)
C Another point on this line would be , when x = 0 , y = 3*-1 + 3 = 0
so it's (0, 0)
D. If the given points are correct the slope is ( as above) = -1.
E. The equation for this line is
y - 3 = -1(x - 1)
y = -x + 1 + 3
y = 4 - x.

Twice a number plus three times a second number is negative one. The first number plus four times the second number is two.
Answer:
Step-by-step explanation:
The first number is -2 and the second number is 1
Answer:
The first number is -2 and the second number is 1.
Step-by-step explanation:
2n + 3s = -1
(n + 4s = 2)-2 Multiply by -2 to cancel the n
2n + 3s = -1
-2n - 8s = -4 Add these equations together
-5s = -5 Divide both sides by -5
s = 1
Plug this into the first equation to find the value of n
2n + 3(1) = -1 Multiply
2n + 3 = -1
- 3 - 3 Subtract 3 from both sides
2n = -4 Divide both sides by 2
n = -2

Answer:
Number of algae in 7 days = 70.355
Step-by-step explanation:
Given:
Algae in beginning = 50
Rate of increasing = 5% per day = 0.05
Number of days = 7 days
Find:
Number of algae in 7 days.
Computation:
