Step-by-step explanation:

Since (3x+3) and 129 are corresponding angles, we can set them equal to one another and solve for x.

3x + 3 = 129

      3x = 126

      /3      / 3

y –5 0 5 10 15
Function B:
y = –4.5x + 15
Function A has a rate change of BLANK and Function B has a rate change of BLANK so Function BLANK has a greater rate of change

Answers

Answer:

5; -4.5; Function A

Step-by-step explanation:

Rate of change for function A is:

(15 - 10)/(5.5 - 4.5) = 5/1 = 5

Rate of change of function B is:

-4.5 as the slope is the rate of change

Comparing the values:

5 > - 4.5

Function A has a greater rate of change

Answer:

Answer:

5; -4.5; Function A

Step-by-step explanation:

Rate of change for function A is:

(15 - 10)/(5.5 - 4.5) = 5/1 = 5

Rate of change of function B is:

-4.5 as the slope is the rate of change

Comparing the values:

5 > - 4.5

Function A has a greater rate of change

(6) QP = QR therefore, triangle QPR is an isosceles triangle.

Since QPR is an isosceles triangle, the base angles are equal.

angle P + angle R + 80 = 180

2x + 80 = 180

2x = 100

x = 50.

That is just the measure of the base angle.

Now take triangle TSR.

Since R = 50, due to angle sum property, we can come up with this equation:

50 + 85 + x = 180

x = 180 - 135

x = 45 <- That's the answer.

(8) Take triangle PSQ, you get angle P = 70 degrees using the angle sum property and algebra.

Now take triangle PSR and you get angle P in the triangle as (180 - 100) / 2 = 40.

Since P = 70, and P in the smaller triangle is 40, 70 - 40 would be the answer.

x = 30 degrees <- That's the answer :D

You have been contracted to replace a countertop in a kitchen. You will get paid $1,000 to do the job. You can complete the job in three days working 8 hours a day. You will need to pay the cost of the materials, which is $525, with the $1,000 that you receive to do the job. How much will you be paid per hour for your time?

Answers

Answer:

$19.79 cents (rounded to the nearest cent)

Step-by-step explanation:

first subtract the amount needed for materials from your total pay

(1000 - 525 = 475)

take 475 and divide that among the hours you work.

475 / 24 = 19.7916666

round that number to the closest money value

Mr. Gomez needs to rent a moving truck. Company "A" charges $75 plus a $50 a day and Company "B" charges $105 plus $35 a day. Write an equation that can tell after how many days would the price be the same.

Answers

Answer: 75+50x= 105+35x , required equation.

Step-by-step explanation:

Let x = Number of days

Given:  Company "A" charges $75 plus a $50 a day.

Total charge = 75+50x

Company "B" charges $105 plus $35 a day.

Total charge = 105+35x

When both are same , equation becomes

75+50x= 105+35x

So, Required equation: 75+50x= 105+35x
