Answer:

30 mm

Step-by-step explanation:

Formula: A = 1/2bh

Substitution: 240 = 1/2b • 16

Solving:

240 = 8b

240 = 8 • <u>3</u><u>0</u>

b = 30 mm

Write the equation of the line that is parallel to y=-0.75x and that passes through the point (8,0)
Mila [183]

Equation of line parallel to y = -0.75x that passes through (8,0) is: y = -0.75x-6

Step-by-step explanation:

Given equation of line is:

y=-0.75x

The coefficient of x is the slope of the line so the slope of given line is: -0.75

As parallel lines have equal slopes so the required equation of line will have the same slope.

The slope-intercept form is:

y = mx+b

Putting the value of the slope

y = -0.75x+b

To find the value of b, putting the point in the equation

0 = -0.75(8)+b\\0 = -6+b\\b = 6

Putting the values of m and b, we get

y = -0.75x-6

Hence,

Equation of line parallel to y = -0.75x that passes through (8,0) is: y = -0.75x-6
