Slope: Take two points from the graph, and do y-y, over x-x.
for ex. (1,2) and (2,4) do 4-2 over 2-1. your slope is 2/1= 2
y-intercept: find the one point on the graph that is exactly on the y-axis.
for ex. (4,0)= your y-intercept is 4
8 + 6 + 9 + 12 + 4x / 5 = x Original Problem.
25 + 4x / 5 = x Addition.
25 + 4x = 5x Multiply each side by 5.
25 = x Subtract 4x from each side.
x = 25 Switch equation around.
Answer: x = 25
Answer: 123 cm^3
Step-by-step explanation:
volume of the cube on the right: (3)(3)(3)=27
volume of the rectangle on the left: (4)(3)(8)=96
total: 96+27=123
Answer:
m∠1=66
m∠3=66
m∠4=114
Step-by-step explanation:
m∠1+m∠2=180
m∠1+114=180
m∠1=66
m∠1=m∠3
66=m∠3
m∠4=m∠2
m∠4=114
