Answer:

y = 4/5x - 18/5

Step-by-step explanation:

y = mx + b

m = 4/5

(2, -2)

-2 = 8/5 + b

b = -10/5 - 8/5 = -18/5

y = 4/5x - 18/5

The right answer is Option A.

Step-by-step explanation:

Given,

Heart rate goal = I

Heart rate reserve = H

70% of H = $\frac{70}{100}H = 0.7H$

Resting heart rate = R

According to given statement,

70% of heart rate reserved is added to resting heart rate to calculate heart rate goal, therefore,

I = R + 0.7H

I=R+0.7H represents the given situation.

The right answer is Option A.

A tile factory earns money by a flat fee for delivery and sales price per tile sold. For one customer the tile factory shipped 1

algol13

10,000 tiles * 0.25 = 2500

3000 -2500 = 500

so the delivery fee is 500 and the tiles cost 0.25 each

so the equation would be y = 0.25x +500

Solve the system of equations using substitution. y = −2x + 1 4x + 2y = −2

Brums [2.3K]

Answer:

No solution

Step-by-step explanation:

The first equation is $y=-2x+1$

The second equation is $4x+2y=-2$ .

Put the first equation into the second one.

$4x+2(-2x+1)=-2$ .

$4x-4x+2=-2$ .

$4x-4x=-2-2$ .

$0=-4$ .

This is not TRUE.

Therefore the system has no solution
