Solve this system of equations using the substitution method y=5x+4 x+12=y

Answers

Answer 1

Answer:

(2,14)

Step-by-step explanation:

Since y=5x+4, you can plug that into the other y in the other equation which would give you x+12=5x+4

Now subtract 12 from both sides

x=5x-8

Subtract 5x from both sides

-4x=-8

Now you divide them both by -4 which gives you x=2

Now plug x in to any of the equations

y=5(2)+4

y=10+4

y=14

Your final answer is (2,14)

Answers

Hello!

This is strange. It seems to give you the answer.

I am assuming your teacher would just like you to identify what a radius is.

All the same, I'll let you know the equation for finding a radius.

r= d × 2 (D is equal to diameter, and r to radius)

If you were given the diameter,, you would simply multiply it by 2 to get your radius.

The correct answer to your question is:

7 inches.

A triangle has side lengths 8, 7, 4. In a similar triangle the smallest side is represented by x + 5 and the longest side is represented by x - 3. What is the value of x?

Answers

Answer:

x = 11

Step-by-step explanation:

8/4 = (x+5)/(x-3)

cross-multiply:

8(x-3) = 4(x+5)

8x - 24 = 4x + 20

4x  = 44

x = 11

Answer:

Step-by-step explanation:

X=11

The longest known is double than samallest known

2(x-3) = x+5

2x-6 = x+5

x= 11

                   11-3 = 8

                   11+5 = 16

Sides of the known triangle    8,7,4     (side 8 double than side 4)

Sides of the similar triangle       16,14,8   (side 16 double than side  8 )

Find the area of the following
kite:
8 cm
2 cm
2 cm
2 cm
2
A = [?] cm2
Enter

Answers

Answer:

Area = 12

Step-by-step explanation:

The perpendicular bisector of the triangle going from upper left to the middle marks the height of the triangle. It's area is found from the standard formula.

Area = b * h / 2

b = 2 + 2 = 4

h = 8

Area = 1/2  * 4 * 8

Area = 1/2 * 32

Area = 16

The smaller triangle is found from all the twos.

b = 2 + 2 same as the larger triangle

h = 2

Area = 1/2 2 * 4

Area = 1/2 8

Area = 4

Total Area = 4 + 16

Total Area = 20

Answer:

Area=20

In the diagram below of triangle HJKHJK, LL is a midpoint of \overline{HJ}HJ and MM is a midpoint of \overline{JK}JK. If LM=71-9xLM=71−9x, and HK=23-xHK=23−x, what is the measure of LMLM?​

Answers

Answer:

Step-by-step explanation:

Since J is the midpoint of HK,  then HJ=JK   and 3x+5=9x-3  solve for x

6x=8   x=8/6=4/3     so HJ=3x+5=3(4/3)+5=9 = JK   HK=2(9)=18

the full segment HK is 18,  each half of it is 9 =HJ=JK

The firm's fixed-charge coverage ratio is 7.89 times

Explanation:

Fixed charge coverage ratio : This ratio deals with fixed payments like: interest payments, lease payments which is before earning before income and taxes.

The formula to compute the fixed charge coverage ratio is shown below:

= (EBIT + Fixed charges) ÷ (Fixed charges + interest expense)

= ($400,000 + $50,000) ÷ ($50,000 + $7,000)

= $450,000 ÷ $57,000

Lila plans to open an account with a deposit of $12,000. She plans to invest the money for 8 years in one of the following accounts:
An account that pays an annual simple interest of 7.5%, or
An account that pays 6% interest compounded annually.
If Lila invests in the account that will earn her more interest over these 8 years, how much interest will she earn?

Answers

9514 1404 393

Answer:

  $7200

Step-by-step explanation:

The amount of simple interest can be found from ...

  I = Prt . . . . . . . where principal P is invested at annual rate r for t years

__

The amount of compound interest can be found from ...

  I = P((1 +r)^t -1) . . . . . same variable definitions

__

The amount of simple interest earned is ...

  I = 12000·0.075·8 = 7200

The amount of compound interest earned is ...

  I = 12000(1.06^8 -1) ≈ 7126.18

In this scenario, the simple interest account earns more interest. If Lila chooses that one, the amount of interest earned is $7200.

You are designing a package for 200 g of snack food that is sensitive to oxygen, and fails when it absorbs 120 ppm of oxygen (by weight). Marketing tells you it wants the snack to be in a plastic pouch measuring 6 inches by 6 inches (ignore seems), so it will have a total surface area available for permeation of 72 in(6" x 6" x 2 sides). You need to recommend an appropriate plastic material for this product, to provide a minimum of 70 days shelf life. Follow these steps: a. Calculate the allowable oxygen gain, in cm at STP. (5 pts) b. At this point, you do not know the material you will use, so you do not know the permeability coefficient or the thickness. The better the barrier the plastic you choose, the thinner the material can be to provide the appropriate barrier. Rather than simple trial and error, a sensible approach is to solve for the ratio of P/L that is required. We can solve the basic permeability equation for this ratio: P = 9 At Ap L Use the information you have to determine the required value for P/L, expressing your answer in cm/(100 in? d atm). (5 pts) c.

Note that chapter 4 presents these values in the units you used in (b) while chapter 14 presents values with different units, so unit conversion would be required. In your answer, state the material you have chosen, its oxygen permeability coefficient, and the minimum thickness you recommend. (Be sure to express the thickness with no more than one decimal place.) Obviously, there is more than one solution to this problem, but you only need one.
