Answer:

y = - 1/5x - 7

Step-by-step explanation:

y = 5x+4. Slope: 5

Slope of the perpendicular line: -1/5

(5,-8)

y - - 8 = - 1/5 (x - 5)

y+8 = -1/5x + 1

y = - 1/5x +1-8

y = - 1/5 x - 7

Your customer is located 100 miles from your office.

OlgaM077 [116]

Answer:

8:02 AM

Step-by-step explanation:

Find out how many minutes it takes to travel one mile:

60 divided by 45= 1.333334 minutes

It takes 1.333334 minutes to travel 1 mile, how long will it take to travel 100 miles:

1.333 times 100 = 133.3334

133.3334 rounds to 133 minutes

Add 15 minutes because you want to arrive early

133+15=148

Divide it by 60

148 divided by 60 = 2.466667

or do

148-120 (2 hours) = 28 minutes

It will take 2 hours and 28 minutes to get there

10:30-2:28= 8:02

Subtract 7x^2−5xy+8y2 from −2x^2−15xy+9y^2

Digiron [165]

Answer

Subtract $7x^2 -5xy+8y^2$ from $-2x^2 -15xy+9y^2$

then;

$-2x^2 -15xy+9y^2 - (7x^2 -5xy+8y^2)$

Remove the bracket we have;

$-2x^2 -15xy+9y^2 - 7x^2 + 5xy - 8y^2$

Like terms are those terms which have same variable to the same power.

Combine like terms;

$-9x^2 -10xy+y^2$

Therefore, Subtracting $7x^2 -5xy+8y^2$ from $-2x^2 -15xy+9y^2$ we get $-9x^2 -10xy+y^2$

Graph: y +2=

olga_2 [115]

Answer:

see below

Step-by-step explanation:

The point-slope form of the equation of a line is ...

y -h = m(x -k)

for a line with slope m through point (h, k).

Comparing this to the given equation, you see that ...

h = -2, m = 1, k = -4

The line has a slope of 1 and goes through the point (-4, -2). This information is useful for graphing.

You can also rearrange the equation to slope-intercept form by subtracting 2 from both sides.

y = x +2

This has a slope of 1 and crosses the y-axis at y=2. It graphs the same as the above.
