Answer:

72.5%

Step-by-step explanation:

(The total number of cards - 40 / Number completed - 29)

1. 40 = 100%

2. Divide both sides of the equation by 40 to get 1 on the right side (40/40 = 1) (100%/40 = 2.5%)

3. multiply both sides of the equation by 29 to find the percentage of cards completed (1*29 = 29 cards finished) (2.5%*29 = 72.5%)

4. Answer: Elin has completed 29 cards which is 72.5% of 40

What is the answer to this <br> y=−x+2<br> y=3x−4<br> ​
Taya2010 [7]

Answer:

x = 1.5

y = 0.5

Step-by-step explanation:

y = −x + 2

y = 3x − 4

so

-x + 2 = 3x -4

2 + 4 = 3x + x

4x = 6

x = 1.5

then y = -x + 2 = -1.5 + 2 = 0.5

Mallory and Aimee save money for summer camp. They both plan to save the same amount of money. Mallory has 35$ and plans to save
Mrrafil [7]

Answer:

0.857 weeks

Step-by-step explanation:

Using the information provided we can create the following equations for the total amount Mallory (M) and Aimee (A) will save after x number of weeks...

M = 35 + 15x

A = 5 + 50x

Now we would need to make both of these equations equal one another and solve for x to calculate after how many week both Aimee and Mallory will have saved the same amount of money

35 + 15x = 5 + 50x  ... subtract 5 and 15x from both sides

30 = 35x  ... divide both sides by 35

\frac{30}{35} or 0.857 = x

Finally, we can see that after 0.857 weeks both Mallory and Aimee will have saved the same amount of money.

*** The process provided is correct but I believe that the actual values for Aimees savings should be $50 and plans to save $5 a week, this would make the final result 1.5 weeks which would make more sense***

Help me please I give brainliest and be serious than you
Naddik [55]

Answer:

15) <u><em>y= 1/2 + 3.75</em></u>

16) <u><em>y = x</em></u>

Step-by-step explanation:

For #15)

<em>Equation used: y=mx+b ; Slope: y₂ - y₁ / x₂ - x₁</em>

1) First, you need to pick any 2 points on the graph. I'll use (6,3) and (8,4).

2.1) Then you'll use the <em>slope </em>equation to find the slope (m) of your equation.

(y) ~ 4 - 3 = 1

(x) ~ 8 - 6 = 2

Slope= 1/2

3) So from the look of the answers, the y here is 3.75 so you can trust that.

4) The final equation is <u><em>y= 1/2 + 3.75</em></u>

<u><em /></u>

For #16)

Use the same steps as #15. You can still choose whatever points/plots you want. Ima use (5,4) and (6,5).

(y) ~ 4 - 3 = 1

(x) ~ 6 - 5 = 1

slope= 1 or x

Answer: y=x

<em>Your welcome for the answer! <3</em>

Based on the table, which best predicts the end behavior
kotykmax [81]

Answer:

Third option.

Step-by-step explanation:

In the picture attached, the question is shown. There we can see that as x gets bigger (x → ∞), f(x) gets smaller (f(x) → -∞ ). On the other hand, as x gets smaller (x → -∞), f(x) gets bigger (f(x) → ∞ ).

Find slope intercept form of 5x+8y=120 passing through (4,5)
yarga [219]

Answer:

y=-(5/8)x+(15/2)  or  y=-0.625x+7.5

Step-by-step explanation:

The question is

Find the slope intercept form of the line parallel to the line 5x+8y=120 passing through (4,5)

step 1

Find the slope of the given line

we have

5x+8y=120

isolate the variable y

8y=-5x+120

y=-(5/8)x+15

The slope of the given line is m=-5/8

step 2

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are the same

so

The slope of the parallel line to given line is m=-5/8

step 3

Find the equation of the line into slope intercept form

The equation of the line into slope intercept form is equal to

y=mx+b

we have

m=-5/8 and point (4,5)

substitute and solve for b

5=-(5/8)(4)+b

b=5+(20/8)

b=60/8=15/2=7.5

substitute

y=-(5/8)x+(15/2)

or

y=-0.625x+7.5
