Answer:

Step-by-step explanation:

Perpendicular lines are lines whose slopes are negative reciprocals of each other

To find the slope of the line we are given, we can rearrange the equation

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

The slope of this line is \frac{4}{5}, so the slope of the other line is \frac{-5}{4}

next, we can use the given point to find the equation y = mx +b

we know m, we can solve for b

y = \frac{-5}{4}(x) + b\\-3 = \frac{-5}{4}(-2) + b\\-3 = \frac{5}{2} + b\\\frac{-6}{2} = \frac{5}{2} + b\\

b = \frac{-11}{2}

so,\\y = \frac{-5}{4}(x) - \frac{11}{2}

1 inch : 100 miles

0.5 inch : X miles

1/100 = 0.5/X

X = 0.5 ÷ 1/100

X = 0.5 × 100/1

X = 50

Which value must be added to the expression x2 – 3x to make it a perfect-square trinomial?
Vitek1552 [10]

Answer:

\frac{9}{4}

Step-by-step explanation:

Given

x² - 3x

To make the expression a perfect square

add ( half the coefficient of the x- term )²

x² + 2( - \frac{3}{2} )x + \frac{9}{4}, thus

x² - 3x + \frac{9}{4}

= (x - \frac{3}{2})² ← a perfect square
