<u>Answer:</u>
square units
<u>Step-by-step explanation:</u>
Knowing the function and that the triangle is formed by both the x and y-axis, you already have the triangle's height, which is 10 (the y-intercept of the functon) To find the base length, all you have to do is find the x-intercept. To do that, simply:
Set function equal to 0 and solve for x:
f(x) = 10 - 
x
0 = 10 - x
x = 10
x = 
This means that the base length of the triangle is also . Now that you have the height and base length, you can
Plug values into the formula for the area of a triangle:
The area of a triangle is 
× height × base
Height = 10, base =
Area = × 10 ×
Area = 5 ×
Area =
I think its 20 but I'm not sure
The perimeters of two opposite triangular faces includes all 4 slant edges and 2 of 4 base edges. The other two base edges are half the base perimeter, so the total length of all edges is
.. 2*(27.5 cm) +(1/2)*(30 cm) = 70 cm
8x7=56, so 56 students can sit at a table, 58-56=2 students without a table.
Your answer would be 2.
Answer: choice C) 3
--------------------------------------------------
Explanation:
Using any two points, we can find the slope through the slope formula. In this case, I'm using the first two points (from the first two rows)
m = (y2 - y1)/(x2 - x1)
m = (1-(-2))/(-1-(-2))
m = (1+2)/(-1+2)
m = 3/1
m = 3
The slope is 3 meaning that each time x increases by 1, y increases by 3.
