The graph represents the data cost for monthly Internet service for a cell phone.

On a coordinate plane, a graph titled Cell Phone Internet Service shows Gigabytes Used on the x-axis and Monthly Cost in dollars on the y-axis. A piecewise function has 3 lines. The 1st line has a closed circle at (0, 15), continues horizontally at y = 15, then has a closed circle at (2, 15). The 2nd line has an open circle at (2, 20) and then continues up to a closed circle at (6, 40). The 3rd line has an open circle at (6, 50) and then continues horizontally at y = 50.
Which function, C(x), represents the monthly cost in dollars in terms of x, the number of gigabytes used in a month?

I don’t really know what you mean here but i guess you mean f(x)=2x+3=0

In that case:
F(x)=2x+3=0
Subtract 3 from both sides:
F(x)=2x=-3
Divide both sides by 2:
F(x)=x=-3/2.

QUESTION 12
Maria bought 6 books for a total of $360.00. Math books cost $80.00 and science books cost $50.00. How many science books did she buy? Your
answer should be a number only.

Answers

Answer: 4 science and 2 math books

Step-by-step explanation:

Let M and S stand for the numbers of math and science books.

We know that M+S = 6 books

and M*80 + S*50 = $360

Rearance the first: M = 6-S

Use this definition of M in the second equation:

(6-S)*80 + S*50 = $360

480-80S + 50S = 360

-30S = - 120

S = 4

Use S=4 in the first equation (M=6-S) to find the number of math books, 2.

Check to see if there number work:

4*($50)= $200

2*($80)= $320160

Total is $360. It works.

A triangle’s three angles sums up to 180 degrees. So the first thing you should do is subtract 50 from 180

180 - 50 = 130

Since it’s an isosceles triangle, ∠A and ∠B are of equal size. So we divide the result, 130, by two. This would give us the m∠A, which is 65.

130/2 = 65

Simplify.

2(4)=8, 8+20=28

so it can simplify into -5 / 28

I need the answer for x if b≠ 0

Answers

Answer:

x=(a+c)/b

Step-by-step explanation:

a−(a+b)x=(b−a)x−(c+bx)

a-ax-bx=bx-ax-c-bx

0-bx=-c-a

x=-(a+c)-/b

x=(a+c)/b and b≠ 0

PLEASE HELP 20 points!

Answers

The answer is y = 0.02 (0.05)^x

Exponential functions follow the form y = ab^x.

a is the y intercept when x is at 0. Because the last part, b^x will just be 1 since any number raised to 0 is 1.

b is the multiplier, and it’s raised to how many times it’s being multiplied.

So like you said, it’s being multiplied by 0.5. b = 0.05. And a=0.02.

Y=5x+b

how do i solve for B?

Answers

Answer:

Y=5x+b

y-5x=b

B= y-5x

hope this helps

Answer:

b = y-5x

Step-by-step explanation:

y =5x+b  

Step 1- Cancelation minus or add the numeric first both side then variable numbers, then variables then exponents ^2 last.

In this case if we were asked to find x we would divide both sides by 5. But we are not asked that and instead asked to find b so we just apply and keep 5x together through add or subtraction.

For exponents we sqrt both sides. But this equation doesnt show any exponents so we stop at -5 each side.

y-5x=b

Step 2 - keep doing to isolate b we have no more to change other than reverse to show b first.

b = y-5x

Anna says that 5 1/3 is not a rational number because it’s not in the fraction form of a/b. Do you agree? plsss help

Answers

Answer:

No.

Step-by-step explanation:

A rational number is a number that can be written in the form a/b, where a and b are integers. A rational number does not have to be written in the form a/b. I just needs to be able to be written in that form.

Can 5 1/3 be written as a fraction of integers?

5 1/3 = 5 + 1/3 = 15/3 + 1/3 = 16/3

5 1/3 = 16/3

16/3 is in the form a/b, where a and b are integers.

Since 5 1/3 can be written as a fraction of integers, it is rational.

Anna is incorrect.
