1.Morgan drives 24 miles due north, then drives 7 miles due east from home to work. What is the distance between Morgan’s home a
Naily [24]

Answer:

1) 25 miles

2) 20 m

Step-by-step explanation:

Number 1 is going to be

a^{2} + b^{2}  = c^{2} because it's a right triangle

So

24^{2} + 7^{2} = c^{2}

625 = c^{2}

c = 25 mile

Number 2 uses the same process, but changing to using C instead of A

a^2 = c^2 - b^2

a^2 = 625 - 225

a = \sqrt(400)

a = 20m

What is the equation of the line that passes through
irinina [24]
Solve equation for y.

5x - y = 3

-y = -5x + 3

y = (-5x + 3)/(-1)

y = 5x - 3

The slope for this equation is 5.

The slope of the equation we want is the negative reciprocal of 5.

Let m = slope of equation we want.

m = -1/5

We are given the point (10,4).

Plug both into the point-slope formula.

y - 4 = (-1/5)(x - 10)

y - 4 = (-1/5)x + 2

y = (-1/5)x + 2 + 4

The equation we want is

y = (-1/5)x + 6
