A. f(x) = 5x
B. f(x) = 5 + 5x
0 Ç. f(x) = 7 + 5x
O D. f(x) = 12 + 5x

Answers

Answer:C. f(x)=7+5x

Step-by-step explanation:

12=5(1)+n

12=5+b

-b+12=5

-b=5-12

5-12=7

-b=7

f(x)=7+5x

I know this because I just answered this question and got it right

The equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The table is given,

From the data given in the table:

12 = 5(1)+n

12 = 5+b

b = 7

The function would be:

f(x) = 7 + 5x

Thus, the equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.

Priya starts with $50 in her bank account. She then deposits $20 each week for 12 weeks.

Write an equation that represents the relationship between the dollar amount (y) in her bank account and the number of weeks (x) of savings

Answers

Answer: y=mx+b is the proper equation

Step-by-step explanation:

Solve the equation: –5x –4 = 16

Answers

The answer is that X equals -4

Let's solve your equation step-by-step.

−5x−4=16

Step 1: Add 4 to both sides.

−5x−4+4=16+4

−5x=20

Step 2: Divide both sides by -5.

−5x /−5 =20/-5

x=−4

can you please explain slope, the y-intercept, how to find the equation and how to graph it properly?​

Answers

Answer:

Slope is a line on a graph, you find slope with the m=yx+b equation. Y intercept is the point that the line crosses the y axis at, it is represented by b. X and Y in the equation are your coordinates. You graph it by starting at your y-intercept and going up in a straight line following the slope calculated.

If x^2+x =3^2/3+3^-2/3 then prove that 3x^3+9x-8=0

Answers

x^2 + 2 = 3^2/3 + 3^-2/3

x^2 = 3^2/3 + 3^-2/3 - 2

x = √(3^2/3 + 3^-2/3 - 2)

x = 0.748888296

Substitute for x in 3x^3 + 9x - 8:

3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.

So it is proved.

What is the solution to the equation 13.7y – 10.6 = 6.2y + 19.4

Answers

Answer: hope this helps :)))

y=4

Step-by-step explanation:

Step 1: Subtract 6.2y from both sides.

13.7y−10.6−6.2y=6.2y+19.4−6.2y

7.5y−10.6=19.4

Step 2: Add 10.6 to both sides.

7.5y−10.6+10.6=19.4+10.6

7.5y=30

Step 3: Divide both sides by 7.5.

7.5y/7.5 = 30/7.5

y=4

Mr. Mohr wants to build a rectangular patio using concrete tiles that are 12 square inches. The patio will measure 13.5 feet by 43 feet. What is the area of the patio? How many concrete tiles will he need to complete the patio?

Answers

Answer: He will need 49 tiles.

Step-by-step explanation:

Given: The patio will measure 13.5 feet by 43 feet.

Area of patio = 13.5 feet x 43 feet   [Area = length x width]

= 580.5 sq. feet

Since area of each concrete tile = 12 sq. inch

Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)

= 580.5 ÷  12

= 48.375 sq. inch ≈49

Hence, he will need 49 tiles.

Answer:

49 tiles

Step-by-step explanation:

Answer: He will need 49 tiles.

Step-by-step explanation:

Given: The patio will measure 13.5 feet by 43 feet.

Area of patio = 13.5 feet x 43 feet [Area = length x width]

= 580.5 sq. feet

Since area of each concrete tile = 12 sq. inch

Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)

= 580.5 ÷ 12

= 48.375 sq. inch ≈49

Hence, he will need 49 tiles.

Ruby misses 10% of the free throws she attempts in a season. How many total free throws did she attempt if she missed 70?

Answers

Answer:

700

Step-by-step explanation:

70x10 = 700

The total number of free throws she attempted is 700.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Missed free throws = 10%

Total free throws = 100%

10% = 70

Multiply 10 on both sides.

100% = 700

Thus,

Total free throws are 700.

Answer:

Look at the numerators, how do you change 90.6 to 22.65? You divide 90.6, but by what? So, we divide to get the number we divide by, which is 4.

90.6 divided by 22.65 = 4

Now, we do the same to the 12 2/5. Since we divided the top by 4, we'll divide 12 2/5 by 4 as well. Change 12 2/5 to a decimal and then divide to get the denominator of the second number.

12 2/5 divided by 4 = 3.1

So, 90.6/12 2/5 = 22.65/3.1

What is the perimeter of a rectangle?

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Given that, the perimeter of a rectangular pool is more than 62 meters.

Let the length of a rectangular pool be l.

The width is at least 10 meters less than the length.

w≤ l-10

So, 2(l+w)>62

2l+2w≥62

Therefore, option D is the correct answer.
