Not sure what you need ;( hope this helps!
answer:
2t−7
step-by-step explanation:
distribute:
=(2)(t)+(2)(−4)+1
=2t+−8+1
combine like terms:
=2t+−8+1
=(2t)+(−8+1)
=2t+−7
good luck :)
hopefully, this helps
have a great day !!
Identifying When to Use a Sample
ch survey is a sample not necessary?
Solve y =-2x
y = 3x + 5
by using substitution method
Answer:
y = -2x
y = 3x + 5
<=> 3x + 5 = -2x
y = -2x
<=> 5x = -5
y = -2x
<=> x = -1
y = -2x
<=> x = -1
y = (-2)(-1) = 2
so (x; y) = (-1; 2)

Use the information given to write the equation for the quadratic function.
a. The x-intercepts are (-4, 0) and (3,0), and the parabola opens down.
b. The vertex is (-8, -2), and the parabola opens up.
Answer:
y = -x² - x/22 + 6/11
Step-by-step explanation:
Standard form, is y = ax² + bx + c
We need to use standard form (though we could use vertex form, but it is easier to do standard form)
Substitute the x and y values that they give into y = ax² + bx + c
Because the parabola passes through...
(-4, 0), then 0 = (-4)²a + (-4)b + c
(3, 0), then 0 = 9a + 3b + c
(-8, -2), then -2 = 64a - 8b + c
So, we get this system:
16a − 4b + c = 0
9a + 3b + c = 0
64a − 8b + c = −2
Because you are learning about parabolas, I am assuming that you can solve a system, but the answers are:
a = -x²/22
b = -x/22
c = 6/11
So, the equation of the parabola is:
y = -x²/22 - x/22 + 6/11
I hope this helps! Feel free to ask any questions!
Serge was curious if a sample third quartile was an unbiased estimator of a population third quartile. He started with a large normally distributed population of test scores whose third quartile was Q3=80 points. He then took a random sample of 6 tests and calculated the third quartile of the sample. He replaced those tests and repeated this process for a total of 40 trials. His results are summarized in the dot plot below, where each dot represents the third quartile from a sample of 6 tests.
Answer:
Sample third quartile appears to be an unbiased estimator of the population third quartile.

Step-by-step explanation:
Solve the system of equations using the substitution method. 2x+y=8
y=x-1
Answer:
x=3
Step-by-step explanation:
If we know that y=x-1, we can just substitute it and replace y with (x-1)
so 2x+y=8 becomes:
2x+(x-1)=8 and we simplify that into:
3x-1=8, add 1 on both sides to make it:
3x=9, divide 3 on both sides
x=3
