Draw a line with a slope of -1/2 going through the point (4,5) already graphed for you. At what point does this line cross the y-axis?
Answer: What is the slope of this line? It's the 'm' term in y=mx+b. In this example, m=1. Therefore the slope of the line is 1, or said another way, the line goes "up" one unit every time it goes "over" one unit.
What is the y-intercept of the line? That's the 'b' term, so it's also 1. That means that when x is 0, y=1. Go ahead and plug x=0 into that equation to verify for yourself.
Step-by-step explanation:
Answer: 7
Equation: y= -1/2x + 7
Step-by-step explanation:
A slope of -1/2 means every x-value you go up by, the y-value goes down by 1/2.
To find an y-intercept you have to go back 4 x-values. So then you need to go up four 1/2 y-values. (simply 2 y-values).

Instructions: Find the measurement of the diagonal indicated in the following parallelogram.
Help!!
Answer:
VX = 24
Step-by-step explanation:
Given :
VJ = 12 units
To find :
VX = ?
Solution:
Since, diagonal of a parallelogram bisect each other.
By this property,
m(VX) = 2[(VJ)]
m(VX) = 2(12)
= 24 units
Therefore, measure of the diagonal (VX) of the given parallelogram is 24 units.
Does the graph represent a function?
A yes
B no
Answer: no
Step-by-step explanation: because it intercepts the y-axis more than once

A=27 cm
A=
15 cm
A=45 cm2
A=
115 cm
A=27 cm
A = 45 cm
Answer:
The surface area is 174 cm^2
Step-by-step explanation:
Since we have the area of each of the faces, to get the total area, we will need to add up the areas of all these faces
Thus, we have that;
A = 45 + 27 + 45 + 15 + 15 + 27
A = 174 cm^2

(Include the base of
the green cube in your

15 ft.
HELP
Answer:
Step-by-step explanation:
We need to find 5 sides of the cube and 4 sides of the pyramid.
For the cube, each side's area is [tex]s^{2}[/tex] with s being the side length. Since there are 5 sides, it would be 5 x [tex]s^{2}[/tex]. s=15, so it would be 5 x 15 x 15, which is 75 x 15 which simplifies into 1125.
For the pyramid, we need to find the area of all 4 triangles. They are all the same triangle, each with a base of 15 and a height of 9. So one triangle's area is 9 x 15/2 = 67.5 --> Since there are 4 triangles, the area of all of them would be 67.5 x 4 which is 270.
1125 + 270 = 1395 cubic ft. (or [tex]ft^{3}[/tex])
A snowboarder leaves an 8-foot tall ramp with an upward velocity of 28 feet per second. The function h =− 16t 8t gives the height h (in 2 + 2 + 8 feet) of the snowboarder after t seconds. When does the snowboarder hit the ground?
Answer:
2 seconds
Step-by-step explanation:
Given that:
h = -16t² + 28t + 8
Using quadratic formula:
[tex]\dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
where;
a = -16
b = +28
c = +8
[tex]= \dfrac{-(28) \pm \sqrt{(28)^2 - 4(-16)(8)}}{2(-16)}[/tex]
[tex]= \dfrac{-(28) \pm \sqrt{784+512}} {-32}[/tex]
[tex]= \dfrac{-(28) + \sqrt{784+512}} {-32} \ \ OR \ \ = \dfrac{-(28) - \sqrt{784+512}} {-32}[/tex]
[tex]=- \dfrac{1}{4} \ \ OR \ \ 2[/tex]
Since we are considering the positive value; Then it will take the snowboarder 2 seconds before it hits the ground.

For a company picnic, Todd fills 30 paper cups with ketchup and Yuki fills 27 paper cups with ketchup. Each paper cup holds 1 ounce. Later, Todd and Yuki learn that two other company employees completed exactly the same task. Question 1 Part A Write a numerical expression to find how many ounces of ketchup the four employees prepared.
Step-by-step explanation:
Todd fills 30 paper cups with ketchup and Yuki fills 27 paper cups with ketchup.
Each paper cup holds 1 ounce
Todd = 30 * 1 = 30 ounces
Yuki = 27 * 1 = 27 ounces
Total ounces = 30 + 27
Later, Todd and Yuki learn that two other company employees completed exactly the same task.
Total ounces = 2 (30 + 27)
Answer:2(30+27)
Step-by-step explanation:
the other company is doing the same thing so you multiply by 2
and we have 30 and 27 so we use those numbers to make
2(30+27)

Find X, BA, AC, and BC of isosceles triangle BAC.
BA= 2x-5; AC = 3x -9;
BC = X-2
Answer:
BA = 3
AC = 3
BC = 2
x = 4
Step-by-step explanation:
Find x
BA and CA are equal Given
2x - 5 = 3x - 9
Subtract 2x from both sides
- 5 = 3x - 2x - 9
- 5 = x - 9
Add 9 to both sides.
- 5 + 9 = x - 9 + 9
4 = x
=========================
BA = 2x - 5
BA = 2*4 - 5
BA = 3
AC = 3x - 9
AC = 3*4 - 9
AC = 12 - 9
AC = 3
BC = x - 2
BC = 4 - 2
BC = 2
Summary
BA = 3AC = 3BC = 2x = 4A pedestrian bridge used as an outdoor market is divided into an eastbound and westbound

Opposite sides of parallelogram ABWC are equal.
Since point C bisects VW, VC=CW
And 3x+1=CW and CW=1/2 of VW
So:

An online store sells two types of speaker docks for smartphones. The higher-priced speaker dock sells for $170 and the lower-priced speaker dock sells for $90. Last week the store sold four times as many lower-priced speaker docks as higher-priced speaker docks. Combined sales totaled $4,770. How many lower-priced speaker docks did it sell?
Answer:
9
Step-by-step explanation:
Let us represent
Low priced = x
High priced = y
An online store sells two types of speaker docks for smartphones. The higher-priced speaker dock sells for $170 and the lower-priced speaker dock sells for $90. Combined sales totaled $4,770.
170x + 90y = $4770
Last week the store sold four times as many lower-priced speaker docks as higher-priced speaker docks.
4x = y
Substitute 4x for y
170x + 90y = $4770
170x + 90(4x) = $4770
170x + 360x = $4770
530x = $4770
x = 4770/530
x = 9
The number of lower-priced speaker docks it sold was 9

Step-by-step explanation:
A system of linear equations is given as x + 3y = 36 and 4x + 5y = 9. Which of the following is a possible first step when solving by substitution? *
1 point
Rewrite the first equation as x = 36 – 3y.
Rewrite the first equation as y = 1/3x + 12.
Rewrite the second equation as x = 9 – 5/4y .
Rewrite the second equation as y = 9 + 4x.
Answer:
Rewrite the first equation as x = 36 – 3y.
Step-by-step explanation:
x + 3y = 36 (1)
4x + 5y = 9 (2)
Using substitution method
From (1)
x = 36 - 3y
Substitute x = 36 - 3y into (2)
4x + 5y = 9
4(36 - 3y) + 5y = 9
144 - 12y + 5y = 9
- 12y + 5y = 9 - 144
-7y = -135
y = -135 / -7
y = 19.3
There is an error with the second equation, 4x + 5y can not be equal to 9
Nevertheless, the first step when solving by substitution is:
Rewrite the first equation as
x = 36 – 3y.
