Answers For The 2 Boxes Please :)

Answers

Answer 1

Answer:

(8, - 5 )

Step-by-step explanation:

Given the 2 equations

3x + 4y = 4 → (1)

- x - 3y = 7 → (2)

Multiplying (2) by 3 and adding to (1) will eliminate the x- term.

- 3x - 9y = 21 → (3)

Add (1) and (3) term by term to eliminate x, that is

0 - 5y = 25

- 5y = 25 ( divide both sides by - 5 )

y = - 5

Substitute y = - 5 into either of the 2 equations and solve for x

Substituting into (1)

3x + 4(- 5) = 4

3x - 20 = 4 ( add 20 to both sides )

3x = 24 ( divide both sides by 3 )

x = 8

solution is (8, - 5 )

Two functions are given below f(x) and h(x) State the axis of symmetry for each function and explain how you found it

Answers

Answer:

The axis of symmetry is the horizontal shift. If I am not wrong, you might be learning about absolute value functions or parabolas.

The absolute value function: f(x)= a|x-h|+k

The parabola (Vertex form of a quadriceps function): f(x)= a(x-h)^2+k

The variable ‘h’ is the horizontal shift, in other words, the axis of symmetry

The diameter of a cake is 12 centimeters, and the area of one slice of cake is 4\pi\ cm.^24π cm. ​2 ​​ . In terms of \piπ, how many full slices can you cut out of the cake?

Answers

Answer:

Total number of slices = 9 slices

Step-by-step explanation:

Given:

Diameter of a cake = 12 cm

Area of one slice = 4π cm²

Find:

Total number of slices

Computation:

Radius of cake = 12 / 2 = 6 cm

Area of circle = πr²

Area of circle = π(6)²

Area of circle = 36π cm²

Total number of slices = Area of circle / Area of one slice

Total number of slices = 36π / 4π

Total number of slices = 9 slices

Answer:

9 full slices

What is the equation in point−slope form of the line passing through (1, 2) and (2, 5)?
(5 points)

A.) (y − 2) = −3(x − 1)

B.) (y − 2) = 3(x − 1)

C.) (y − 1) = −3(x − 2)

D.) (y + 2) = 3(x + 1)

Please make sure the answer is correct

Answers

Answer:

B

Step-by-step explanation:

First, find the slope by using change in y divided by change in x.

Change in y = 5 - 2 = 3

Change in x = 2 - 1 = 1

This means that the slope is 3/1 = 3.

Then, you put it in the point-slope form so:

(y - 2) = 3(x - 1)

Step-by-step explanation:

Jack and Jill applied for the same credit card from the same bank. The bank checked both of their FICO scores. Jack had an excellent credit rating, and

Jill had a poor credit rating


Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?


Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?


If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Answers

Answer:

a. Jack's monthly periodic rate = 1%

b. Jill's monthly periodic rate = 1.75%

c. Amount paid more by Jill than Jack = $5.25

Step-by-step explanation:

a. Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?

Jack's monthly periodic rate = Jack's annual percentage rate (APR) / Number of months in a year = 12% / 12 = 1%

b. Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?

Jill's monthly periodic rate = Jill's APR / Number of months in a year = 21% / 12 = 1.75%

c. If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Jack's finance charge = Jack's monthly periodic rate * Average daily balance = 1% * $700 = $7

Jill's finance charge = Jill's monthly periodic rate * Average daily balance = 1.75% * $700 = $12.25

Amount paid more by Jill than Jack = Jill's finance charge - Jack's finance charge = $12.25 - $7 = $5.25
