Elena and Jada each make money by helping out their neighbors.


Elena babysits. Her earnings are given by the equation y=8.40x, where x represents how many hours she works and y represents how much money she earns.


Jada earns $7 per hour mowing her neighbors’ lawns.


A. Who makes more money after working 12 hours? How much more do they make? Explain how you know.


B. What is the rate of change for each situation and what does it mean?


C. How long would it take each person to earn $150? Explain or show your reasoning.

Answer:

Yes, Mina is correct

Step-by-step explanation:

Let the triangles be A and B

Given

Triangle A:

[tex]Angles = 34, 57[/tex]

Triangle B:

[tex]Angles = 89, 57[/tex]

Required

Is Mina's claim correct?

First, we calculate the third angle in both triangles.

For A:

[tex]Third\ Angle = 180 - 34 - 57[/tex]

[tex]Third\ Angle = 89[/tex]

For B:

[tex]Third\ Angle = 180- 89 - 57[/tex]

[tex]Third\ Angle = 34[/tex]

For triangle A, the angles are: 34, 57 and 89

For triangle B, the angles are: 34, 57 and 89

Since both triangles have the same angles, then by the postulate of AAA (Angle-Angle-Angle), the triangles are similar.

Answer: 0.09 mg

Step-by-step explanation:

To find out the milligrams in the blood after 10 hours you just need to replace the 'h' in the equation to 10.

= 5e⁻⁰°⁴ˣ¹⁰

= 5e⁻⁴

= 0.09157819444

= 0.09 mg

Answer:

I can help you because  I am learning  the same time. ok

Step-by-step explanation:

1 step (5x-2) = (8x-7)

expand (8x-7) = 8x-7 so 5x-2=8x-7

add 2 to both  side 5x-2+2=8x-7+2

simplify 5x=8x-5

subtract 8x from both side 5x-8=8x-5-8

simplify -3x=5

divide both sides by -3

3x 3 =5x

simplify x=5 over 3

Answer:y=1/5x+5

Step-by-step explanation:

m=slope so plug in the slope you already have which is 1/5

b= y intercept so plug in your y intercept which is 5

Answer:

p = 7/2 or 3.5

Step-by-step explanation:

-4p + 9 = -5

-4p = -14 (subtracted 9 from both sides)

p = -14/-4 = 7/2

Answer:

p=3.5

Step-by-step explanation:

-4p+9=-5

-9

-4p=-14

p=3.5

Answer:

[tex]\sqrt{45}[/tex]

Step-by-step explanation:

Ultimately, you want to find the hypotenuse from the distance of Point A to Point B.  From point A to the center of point B, it is nine units up and from there it is three units to the right of Point B.  Use the Pythagorean theorem to get your hypotenuse in which you should get 45 as your hypotenuse and when you divide it, it is [tex]\sqrt{45}[/tex].

Answer:

24 and 56

Step-by-step explanation:

8*3=24

7*8=56

Answer:

P = -4

Step-by-step explanation:

Assuming that x = 20 and y = 24, you have to plug in these numbers for x and y to get to this equation P = 20 - 24.  You should get -4 when you subtract 24 from 20 giving you a negative answer.

Answer: x=44.6

Step-by-step explanation: 30²= 900

                                             33²= 1089

                                             900²+1089²=1989²

                                             1089²=44.6

                                             x=44.6

Answer:

  all are functions except Relation 2

Step-by-step explanation:

If any input value (first of an ordered pair) is used more than once, the relation is not a function. Output values can be used as often as you like.

Only Relation 2 is not a function.

brainliest plzzzzz

Step-by-step explanation:

2(x-2) - 3(x-4)

Simplify:

2(x-2)-3(x-4)

2x-4-3(x-4)

Distribute:

2x-4-3(x-4)

2x-4-3x+12

Add the numbers:

2x-4-3x+12

2x+8-3x

Combine like terms:

2x+8-3x

-x+8

Hence Solution = -x+8

Answer:

105

Step-by-step explanation:

0 (104) is equal to 0, so let's cross that out. 103 times 102 is definitely not equal to 105. The third one is 105. The fourth one is not 105. The last one is not 105 either.

Answer:

(x - 3)² + (y + 1)² = 65

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

The centre C is at the midpoint of the endpoints of the diameter.

Using the midpoint formula to find C

C = ( [tex]\frac{7-1}{2}[/tex], [tex]\frac{6-8}{2}[/tex] ) = ( [tex]\frac{6}{2}[/tex], [tex]\frac{-2}{2}[/tex] ) = (3, - 1 )

The radius is the distance from the centre to either of the endpoints of the diameter.

Using the distance formula to find r

with C (3, - 1 ) and (7, 6 ) , then

r = [tex]\sqrt{(7-3)^2+(6+1)^2}[/tex]

  = [tex]\sqrt{4^2+7^2}[/tex]

  = [tex]\sqrt{16+49}[/tex]

  = [tex]\sqrt{65}[/tex]

Then equation of circle is

(x - 3)² + (y - (- 1) )² = ([tex]\sqrt{65}[/tex] )², that is

(x - 3)² + (y + 1)² = 65 ← equation of circle
