Answer:
x + 2(2x-4) = 10
Step-by-step explanation:
Here in this question, we want to select which is the correct answer if we substitute for the value of y in the second equation, using the first.
In the first, we have;
y = 2x -4
Now, let’s input this value of y into the second equation.
By direct substitution, what we have is the following;
x + 2y = 10
—-> x + 2(2x -4) = 10
Answer:
y=-2x+1
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of one another. slope 1/2 perpendicular will be -2/1=-2
y-5=-2(x-(-2))
y-5=-2(x+2)
y-5=-2x-4
y=-2x-4+5
y=-2x+1
Answer:
3 ft, 3ft, 5ft => 45 cubic feet
6 ft, 2 ft, 4 ft => 48 cubic feet
7 ft, 2 ft, 2 ft => 28 cubic feet
6 ft, 5 ft, 2 ft => 60 cubic feet
Step-by-step explanation:
Recall: formula for volume of a rectangular prism is given as, V = L × W × H
✔️Volume of rectangular prism with the following dimensions:
L = 3 ft
W = 3 ft
H = 5 ft
V = 3 × 3 × 5
V = 45 cubic feet
✔️Volume of rectangular prism with the following dimensions:
L = 6 ft
W = 2 ft
H = 4 ft
V = 6 × 2 × 4
V = 48 cubic feet
✔️Volume of rectangular prism with the following dimensions:
L = 7 ft
W = 2 ft
H = 2 ft
V = 7 × 2 × 2
V = 28 cubic feet
✔️Volume of rectangular prism with the following dimensions:
L = 6 ft
W = 5 ft
H = 2 ft
V = 6 × 5 × 2
V = 60 cubic feet
