A dog groomer earns $450 each week plus $8 per dog she washes. She uses the expression 450 + 8d to find her total earnings each week for d dogs. What were her total earnings if she washed 8 dogs last week? .PLs help i need it by today ¯\_(ツ)_/¯

$514

Step-by-step explanation:

by using the formula : 450 + 8d

we can notice that we have to multiply the number of days that the dog is washed by 8

therefore if 8 dogs were washed that week then put d as 8 in the equation

450 + 8 *(8)

450 +64

=514

the total earnings last weeks are $514

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
