Answer:
9
Step-by-step explanation:
Get the equation into the form y = mx + c
3x + y - 9 = 0
y = -3x + 9
The y intercept is 9
A = L x W.
2/5 x 1/5 = 2/25
A= 2/25
I hope this helps!
The y-intercept is where the graph goes through the y-axis (the vertical line in the center). It goes through at y=-9, so the coordinates would be (0,-9), since it is (x,y).
Answer:
B. 192.5 ft³
To find the volume of a triangle prism, multiply the base, height, and length together, and then divide it by 2 (or multiply that by 0.5).
(5 * 7 * 11)/2
Multiply 5 by 7 to get 35.
(35 * 11)/2
Multiply 35 by 11 to get 385.
385/2
192.5 ft³ is the volume of this triangluar prism.
