slope-intercept form: y = mx + b

m = the slope and b = the y-intercept.

We know that the line passes through x-coordinate 1 and y-coordinate 1 and has a slope of 2

Let's plug our numbers into the slope-intercept form

1 = 2(1) + b

Simplify the right side

1 = 2 + b

Subtract 2 from both sides

-1 = b

The final answer: y = 2x - 1

the answer is A.) y=2x-1

substitute (1,1) in for y and x
1=2(1)+b
1=2+b
-1=b

∠A and ∠ B ∠B are complementary angles. If m ∠ A = ( 2 x − 10 ) ∘ ∠A=(2x−10) ∘ and m ∠ B = ( x − 2 ) ∘ ∠B=(x−2) ∘ , then find the measure of ∠ A ∠A.

Answers

Answer:

Angle A = 58 degrees

Angle B = 32 degrees

Step-by-step explanation:

First of all, we will need to know that complementary angles are angles that sum up to 90 degrees.

This means that if we add the values of angle A and angle B, they will both sum up to 90 degrees.

i.e (2x-10) + (x-2) = 90

3x -12 = 90

3x = 102

x = 34 degrees

We can substitute this value of x into the equations for angles A and B

A = (2 X (34) - 10 ) = 58 degrees

B =  ( 34 - 2) = 32 degrees

Therefore, angles A and B are 54 and 32 degrees respectively.

Check: We can add the two angles to see if we get 90 degrees. 58 + 32 = 90 degrees. This shows that the two angles are complementary and our answer is correct.

During the summer, the height of the water in the pool decreased by 5 inches each week due to evaporation. What is the change in the height of the water over an 8 week period?

Answers

Answer:

40 inches

Step-by-step explanation:

We know that the height of water in a pool decreased 5 inches per week.

This means that we can form the equation [tex]y=-5x[/tex], since the amount of water remaining is proportionate to the amount of weeks that have passed.

We know [tex]x=8[/tex], since we need to find the change for 8 weeks.

[tex]y = -5\cdot 8[/tex]

[tex]-5 \cdot 8 = -40[/tex]

[tex]y=-40[/tex]

The change will be the absolute value of -40, which just makes it positive, so 40.

Hope this helped!

Answer:

40 inches evaporated

Step-by-step explanation:

5 in / week

Multiply 5 in by 8 wks

= 40 inches of water evaporated over 8 wks

To ensure profits, a store is going to sell a sweater for 115 percent of the production cost. It costs $10 to make the sweater. Below are the calculations for finding the selling price. What mistake did the store owner make? (Original Cost)(Percent) = New Cost ($10)(0.115) = $1.15 The new cost is correct. The owner should have divided by 0.115. The owner should have multiplied by 11.5. The owner should have multiplied by 1.15.

Answers

Answer:I did the test and the answer is The owner should have multiplied by 1.15.

Step-by-step explanation:

Sample text

To make the calculation 115 percent of the production cost , the owner should have multiplied by 1.15 to the production cost.

What is percentage?

" Percentage is defined as the hundredth part of any given number".

According to the question,

Production cost of a sweater = $10

To ensure profit , selling price = 115 percent of the production cost

(Original Cost)(Percentage)

[tex]= (10)(\frac{115}{100} )[/tex]

[tex]= $11.5[/tex]

Hence, to make the calculation 115 percent of the production cost , the owner should have multiplied by 1.15 to the production cost.

Ly: y = 60x + 25

60x + 25 = 35x + 100

25x + 25 = 100

25x = 75

x= 3 weeks

Erika: y = $35(3) + 100= 105 + 100 = $205

The measure of angle ABC = ABD + DBC = 95 degrees.

Let's plug our values from the picture into our equation above.

95 = 2x + 23 + 9x - 5

Combine like terms

95 = 11x + 18

Subtract 18 from both sides

77 = 11x

Divide both sides by 11

7 = x

Angle ABD = 2x + 23 = 2(7) + 23 = 14 + 23 = 37 degrees.

Angle DBC = 9x - 5 = 9(7) - 5 = 63 - 5 = 58 degrees.
