Answer:
Step-by-step explanation:
1. Find the slope:
7 -3/ 1 + 1 = 4/2 = 2 = m
2. Find b by plugging in the m and one of the points given into y = mx + b
7 = 2 ( 1 ) + b
7 = 2 + b
5 = b
3. Write the equation using the m and the b you just found
y =2 x + 5
Answer:
66 
Step-by-step explanation:
Vol = Bh where B is the area of the base and h is the distance between the bases (height)
The base is a right triangle and has an area of
B = 1/2bh = 1/2(4)(3) = 6
h = 11
V = 6(11) = 66
The answer to your equation is x=2.
Why? Because..................
3x*2=12
Divide both sides by 3*2
3x*2/3*3=12/3*2
Simplify
12/3*2
x=6

Answer:
C. 112.5cm^3
Step-by-step explanation:
Volume= Length x Width x Height
V= 7.5 x 1.5 x 10
V=112.5
