Answer:
(-1, -4.5)Step-by-step explanation:
[tex]y=\frac12(x+4)(x-2)\quad\implies\quad x_1=-4\,,\ \ x_2=2[/tex]
vertex is (p, q) where:
[tex]p=\dfrac{x_1+x_2}2=\dfrac{-4+2}2=\dfrac{-2}2=-1\\\\q=f(p)=\frac12(-1+4)(-1-2)=\frac12(3)(-3)=-\frac92=-4.5[/tex]
So the vertex is: (-1, -4.5)

Use the calculator to evaluate the function y = 1 *2 - 2 for the given values of x.
x= 4, y =
x=6, y=
Answer:
when x= -4, y= 2
when x= 6, y =7
Step-by-step explanation:
We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)^2 -2
first we do the exponent
y= 1/4 (16) - 2
Then the multiplication
y= 4-2
then subtraction
y=2
For the second problem, it becomes y= 1/4 (6)^2 -2 We follow the same steps
y = 1/4 (36) - 2
y= 9-2
y= 7
The function y = 1 *2 - 2 for the given values of x are
when x= -4, y= 2
when x= 6, y =7
We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)² -2
First we do the exponent
y= 1/4 (16) - 2
Then the multiplication
y= 4 - 2
then subtraction
y = 2
For the second problem, it becomes y= 1/4 (6)² -2 We follow the same steps
y = 1/4 (36) - 2
y = 9 - 2
y = 7

Answer:
Avery earns $1,080 during summer
Avery weekly earnings = $1,080 / 12
= $90
Carmen earns $960 during summer
Carmen weekly earnings = $960/12
= $80
Carmen earns more money during summer break
Step-by-step explanation:
Avery payment = $360 every four weeks
Carmen payment = $480 every six weeks
summer break lasts a total of 12 weeks
Avery pay during summer = Total summer break weeks / 4 weeks × payment per 4 weeks
= 12 / 4 × $360
= 3 × $360
= $1,080
Carmen pay during summer = Total summer break weeks / 6 weeks × payment per 6 weeks
= 12 / 6 × $480
= 2 × $480
= $960

f(x) = -2x
f(x) = 2x-1
f(x) = 2x+1
Answer: f(x) = 2x+1
Step-by-step explanation: Substitute the variable with the “x” values in the chart to check your answers.
1. f(x) = 2x+1
Add in the “x” value
f(x) = 2x(-1) or 2 multiplied by -1
f(x) = -2 + 1
If the answer is equal to your “y” value , it can represent the function.

HELP ME PLEASEEEE
I only know how to do this in division, not multiplication
Answer:
360 × 30
= (360 × 3) × 10
= 1080 × 10
= 10800
Step-by-step explanation:
For the first two blanks, we will have to find a pair of factors of 30 that will make this the easiest to solve. Lets pair up all of the factors of 30.
1, 30
2, 15
3, 10
5, 6
So now we have found all of the factors of 30. We can eliminate 1 and 30, since we will just end up with 360 × 30 in the second line. We could use 2 and 15, but we will end up with _____ × 15 in the second line, which would be more difficult to solve for than the other two options. Now, you should use any one of the final two pairs of factors. I would use 3 and 10, since I find it much easier to multiply something by 3 and 10 than 5 and 6.
Lets put 3 in the first blank and 10 in the second blank. We will end up with:
(360 × 3) × 10
Now 360 × 3 would be 1080. So the second line would be:
1080 × 10
1080 × 10 would equal 10800. So the final line and the final blank would be:
10800
So in order, the lines would be:
= (360 × 3) × 10
= 1080 × 10
= 10800

What is an eqination of the line that passes through the point (-3, -7) and parallel to the line 3x-y=5
I need the y=mx+b
Answer:
y = 3x + 2
Step-by-step explanation:
First you need to change the way the equation is said into a easier form:
y = 3x - 5
Since the line is parallel, you can use the same slope of 3:
y = 3x + b
Now you plug in the coordinates into the equation and solve for b:
-7 = 3 ( -3) + b
-7 = - 9 + b
-7 + 9 = b
2 = b
Now plig this into the equation and you have the answer
y = 3x + 2
