Which lists all of the y-intercepts of the graphed
function?
O (0,-3)
O (-1,0) and (3,0)
O (0, -1) and (0,3)
O (-1,0), (3, 0), and (0, -3)
From the graph, we can see that the graph crosses the y-axis at (0,-3) Hence, the correct answer is A (0,3).
What is the y-intercept of a function?The intersection of the graph of the function with the y-axis gives the y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
The y-intercept is where a line crosses the y-axis, so this is the point where x = 0.
From the graph, we can see that the graph crosses the y-axis at (0,-3)
Hence, the correct answer is A (0,3).

perform the subtraction -2 - 15=
the answer is -17 :)
B is incorrect so it's not the answer...
Answer:
x^2 - 4x - 3
Step-by-step explanation:
f(x) = x^2 - 6x
g(x) = -2x + 3
(f - g)(x) is the subtraction of the functions, f(x) - g(x)
You need to write it carefully using parentheses for function g(x).
(f - g)(x) = f(x) - g(x) =
= x^2 - 6x - (-2x + 3)
Now take care of the parentheses by distributing the negative sign to its left. It will change every sign inside the parentheses.
= x^2 - 6x + 2x - 3
= x^2 - 4x - 3

Step-by-step explanation:
Giving the following information:
A text message plan costs $2 per month plus $0.23 per text.
First, we need to structure the total cost formula:
y= total cost
x= number of text messages
y= 2 + 0.23x
Now, we can calculate the total cost for any number of text:
x= 200
y= 2 + 0.23*200

D. 10
E. 173
Answer:
7.5
Step-by-step explanation:
8x÷4=12÷4
2x=3
x=3/2=1.5

Answer:
7.5 or 7½
Step-by-step explanation:
8x = 12
x = 12/8 (12/4 / 8/4)
x = 3/2
x = 1.5
2y + 10 = 22

A cyclist rode 3.75 miles in 0.3 hours. How fast was she going in miles per hour? Round your answer to the tenths (first) decimal place.
Answer:
12.5 miles per hour
Step-by-step explanation:
The speed is the distance divided by time.
3.75 miles/0.3 hours= 12.5 miles per hour
Answer:
12.5 miles per hour
Step-by-step explanation:
To answer this question you have to make sure that the hours (denominator) equals to 1. To do this, divide 3.75 by 0.3, thus making the 0.3 hours into 1 hour. This results in 12.5 miles per hour, the correct answer. Hope this helped!

Can an absolute value equal a negative?
how do i do this? -X= 8
Answer:
x = -8
Step-by-step explanation:
-X= 8
Multiply by -1
-X*-1= 8*-1
x = -8
Answer:
x = -8
Step-by-step explanation:
Multiply both side of the equation by -1
-x(-1) = 8(-1)
On the x side, the negatives cancel each other out, making x positive.
On the 8 side, the negative makes the 8 into -8.
x = -8
(essentially, switch the negative/positive signs)

am i right with the question and if i m can you explain further i think i awser is y=10x
You are correct.
C is the constant, which is also called the slope.
Slope = change in y over the change in x:
Slope = 160-30 / 16-3 = 130/13 = 10
The equation would be y = 10x
If 1/5 of the money in a cash box is 30 dollars, how much money is in the cash box?
Answer:
Money in the cash box is $150
Step-by-step explanation:
Let
x = money in the cash box
1/5 of the money in a cash box is 30 dollars
1/5 of x = $30
1/5 * x = 30
1/5x = 30
Divide both sides by 1/5
x = 30 ÷ 1/5
= 30 × 5/1
= 150/1
x = $150
Money in the cash box is $150
In the diagram below of triangle KLM, N is a midpoint of KL and P is a midpoint
of LM. If mZPNL = 2x + 61, and MKN = 97 - 7x, what is the measure of
ZPNL?
Answer:
Solution:
(1/12)^(-2b) * 12^(-2b+2) = 12
(12^-1)^(-2b) (12)^(-2b+2) = 12
(12^2b)(12)^(-2b+2) = 12
12^(2b-2b+2) = 12
12^2 = 12
144 does not equal 12
No solution.
Step-by-step explanation:
The measure of angle PNL will be equivalent to 69 degrees.
What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a triangle KLM such that N is a midpoint of KL and P is a midpoint of LM.
Triangles LMP and LKM are similar to each other. Therefore, PN will be parallel to MK. So angle PNL will be equal to angle MKN. Therefore -
2x + 61 = 97 - 7x
9x = 97 - 61
9x = 36
x = 4
So, angle PNL will be equal to -
2 x 4 + 61
69 degrees
Therefore, the measure of angle PNL will be equivalent to 69 degrees.

Step-by-step explanation:
just answered it
The transformations of the graph is a reflection in the x-axis followed by a translation down by 7 units.
Option (C) is correct.
It is required to choose the transformations of the graph.
What are transformations?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
We have a given a graph of y = f(-x) – 7.
The transformations in order are the following:
Reflection over the x-axis.
Horizontal translation of 7 units to the left.
Therefore, the transformations of the graph is a reflection in the x-axis followed by a translation down by 7 units.

A scale drawing of a school bus has a scale of 1 inch to 5 feet. If the length of the school bus is 6 inches on the scale drawing, what is the actual length of the bus? Explain or show your reasoning. *
Answer: 30 Feet
Step-by-step explanation:
In Technical drawings scales are used to reduce the size ( scaling ) of drawings so they fit in our drawing sheets. in this example above the drawer stated that 1inch was representing 5feet. what this means is that because we can’t get a drawing sheet which would be 40-100 feet wide we need to rescale our drawing to fit into the available sheet. So by saying 1inch equals 5feet this means the school bus is 30Feet in length.
