Answer:
Step-by-step explanation:
f(x)=2x+3
f(x)=0
2x+3=0
2x=-3
x=-3/2
x=-1.5
when x=0,y=f(x)=2(0)+3=3
so one point is (0,3)
when x=2,y=f(x)=2(2)+3=4+3=7
so point is (2,7)
Draw a line through (0,3) and (2,7)
see where it cuts x-axis.
it is the zero of the linear equation.
zero is x=-1.5

There is a guitar that originally costs $249.99. It is on sale for 15% off. You also have to pay 6% sales tax. How much will you pay for the guitar? Please show work!!!
Answers
Answer:
225.24099
Step-by-step explanation:
249.99(0.15) = 37.4985
249.99 - 37.4985 = 212.4915
212.4915(0.06) = 12.74949
212.4915 + 12.74949 = 225.24099
The sum of three consecutive even integers is 486. Find all three integers.
Answers
Answer:
161 + 162 + 163 = 486
Step-by-step explanation:
(X) + (X + 1) + (X + 2) = 486
X + X + 1 + X + 2 = 486
3X + 3 = 486
3X + 3 - 3 = 486 - 3
3X = 483
3X/3 = 483/3
X = 161

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
g(x) = 10 - 2x
For x = 7,
g(7) = 10 - 2 x 7
g(7) = 10 - 14
g(7) = -4
Thus,
g(7) = -4.

A beekeeper pays $30 to rent a booth at a farmers' market.
She charges $5 for each jar of honey. The graph shows this
situation, which is modeled by the equation y = 5x - 30.
Which of the following is true?
A. The value of x can be negative.
B. The value of y can be negative.
C. The value of x can be fractional.
D. The value of y cannot be zero.
X
Answers
Answer: The answer is A
Step-by-step explanation: because 5x-30= -150 because I looked it up
Answer:
B. The value of y can be negative.
Step-by-step explanation:
The value of y can be negative, which means the beekeeper wasn't able to sell a lot of jars that could compensate the amount he paid for the booth. It also means he didn't have any profit, rather, he incurred a loss.
For example, if the beekeeper sold only 5 jars of honey, the solution will look like this:
Let x be the number of jars of honey the beekeeper sold.
y = 5x - 30y = 5(5) - 30y = 25 - 30y = -5This means that the beekeeper has a loss of $5.

Jayla's bank account increased by 7% this year. Write an equation to represent the relationship between the amount that Jayla started with, b, and the amount she has now, c.
Answers
The equation that represents Jayla's current account balance with the initial amount is c=1.07b.
What is Compound Interest?
Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.
It is given by the formula,
[tex]A = P(1+\dfrac{r}{100})^t[/tex]
where, A is the value after t period of time, and,
r is the rate of interest.
Given to us
Jayla's bank account increased by 7% this year.
The amount that Jayla started with is b,
The amount that Jayla has now is c.
The equation that represents Jayla's AccountWe know the general equation for compound interest is given as,
[tex]A = P(1+\dfrac{r}{100})^t[/tex]
Substituting the values we will get,
[tex]c=b(1 + \dfrac{7\%}{100})^1\\c = b(1.07)[/tex]
Hence, the equation that represents Jayla's current account balance with the initial amount is c=1.07b.

Mariah has a spinner that has 10 equal sections, each containing a different number from 1 to 10. Mariah determines about how many times the spinner will land on a number that is greater than 7 in 250 spins, and her work is shown below.
P (number greater than 7) = StartFraction Number greater than 7 over Total number of sections EndFraction times number of spins = StartFraction 4 over 10 EndFraction (250) = 100.
What mistake did Mariah make, if any?
Mariah has the formula reversed; it should be the total number of sections over the numbers greater than 7.
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.
Mariah should multiply by the number of sections in the spinner rather than the total number of spins.
Mariah calculated the prediction correctly and did not make any mistakes.

Show how to rewrite 1/5 with the denominator 10
Answers
The denominator is the bottom number.
To change the 5 to 10, you would multiply 5 by 2: 5 x 2 = 10
Because you multiplied the 5 by 2, you also need to multiply the numerator ( top number) by the same amount.
1 x 2 = 2
So 1/5 = 2/10
The answer is 2/10
