(C) 2y = 9x

(D) –4y = 18x
unit rate =
Answers
The unit rates of y = –2x is -2, for y = 0.75x the unit rate is 0.75, for 2y = 9x then the unit rate is 4.5 and for equation –4y = 18x the unit rate is -4.5
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Unit rate is the ratio of two different units, with denominator as 1.
For y = –2x then the unit rate is -2
For y = 0.75x then the unit rate is 0.75
For 2y = 9x then the unit rate is 9/2 or 4.5
For –4y = 18x then the unit rate is -18/4 or -4.5
Hence, the unit rates of y = –2x is -2, for y = 0.75x the unit rate is 0.75, for 2y = 9x then the unit rate is 4.5 and for –4y = 18x the unit rate is -4.5

The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle.
Answers
Answer:
50 degrees
Step-by-step explanation:
The angles of a triangle add up to 180 degrees. We would set up the equation like this:
2x+18 + 4x+11 + 55 = 180
Combine like terms:
6x + 84 = 180
Solve for x:
6x = 96
x = 16
We substitute 16 back in for x and see the measure of the smallest angle.
2(16)+18 = 50
4(16)+11 = 75
55
The smallest angle here in 50 degrees.
Answer:
2x + 18 = 50
Step-by-step explanation:
2x + 18 + 4x + 11 + 55 = 180
6x + 84 = 180
180 - 84 = 96
6x = 96
96/6 = 16
x = 16
2(16) + 18 = 50
55
4(16) + 11 = 75

h + 86.43 = 531.79
h = ___________
Answers
because you bring the 86.43 over to the 531.79. which would make 86.43 a negative number. so you subtract 531.79 by 86.43
Answer:
h=445.36
Step-by-step explanation:
Subtract both sides by 86.46
531.79 - 86.43 = 445.36
Check answer by plugging it back in
445.36 + 86.43 = 531.79

so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together
l= length
w=width
a=area
4*8=32
4*8=32
6*4=24
6*4=24
6*8=48
6*8=48
48+48+24+24+32+32=208
208[tex]cm^{2}[/tex]
for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.
for the triangles you're gonna wanna use the equation 1/2b*h=a
b= base
h=height
a=area
