The inequality 7-2/3x < x-8

romanna [79]

Am going to presume you want it solved.
Please pardon my presumption

7 - (2/3)x < x - 8, Take all the x to one side of the inequality
-(2/3)x-x < - 8 -7
-(5/3)x < - 15 Divide both sides by -5/3 and inequality sign changes

x > (-15)/(-5/3)

x > 15 * 3/5 . 5 into 15 is 3.

x > 3*3

x > 9

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.

Write the equation of the line that has an x-intercept of -3 and passes through the point (-3, 7).

Marina86 [1]

Answer:

$x=-3$

Step-by-step explanation:

'x = -3', when graphed, passes through the point (-3,7) and (-3,0).

Since the line passes (-3,0), the x-intercept is -3.

(-3, 7) lies on the equation.

I have attached a picture of the graphed equation.

'x = -3' should be the correct answer.
