Answer:

2.5 cm

Step-by-step explanation:

The volume of a triangular prism is cross section × length.

The cross section area is the triangle area. The triangle length is 4 cm, the height is not given. The length of the triangular prism is 7cm.

4 × h × 1/2 × 7 = 35

14h = 35

h = 35/14

h = 5/2

The height of the triangular cross section is 2.5 cm.

(4,7) and (5,1) as an equation
monitta

Answer:

y = -6x + 31

Step-by-step explanation:

In order for us to make this an equation of the form y = mx + b we have to find the slope.

The formula for slope is rise/ run. The rise is 6 and the run is -1.

So, the slope is 6/-1 or -6.

Our equation is now: y = -6x + b

Substituting 4,7 into the equation we get 7 = -24 + b

So, b = 31.

To check out answers we substitute 5,1 in and it works.

Which point-slope equation represents a line that passes through (3, –2) with a slope of -4/5?
alexira [117]

Answer:

y+2=-\frac{4}{5}(x-3)

C is correct equation.

Step-by-step explanation:

We are given a point and slope of a line. Using point slope form formula to find the equation of line and match the correct option.

Formula:

y-y_1=m(x-x_1)

where,

slope (m)=-\frac{4}{5}

Point:(x_1,y_1)\rightarrow (3,-2)

Equation of line:

y-(-2)=-\frac{4}{5}(x-3)

y+2=-\frac{4}{5}(x-3)

Thus, C is correct equation of given information.
