The value of function h (-5) will be;
⇒ h (-5) = 10
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The function is,
⇒ h (x) = - 4x - 10
Now,
Here, The function is,
⇒ h (x) = - 4x - 10
So, To find the value of h (-5) as;
Substitute x = - 5 in above equation as;
⇒ h (x) = - 4x - 10
⇒ h (-5) = - 4 × -5 - 10
⇒ h (-5) = 20 - 10
⇒ h (-5) = 10
Thus, The value of function h (-5) will be;
⇒ h (-5) = 10

The polynomial simplified would be a^2 + 30
I hope this helps you:))
P.S. Might I recommend a good online calculator for these types of problems. It's called Symbolab. I use it every day and it's a lifesaver. It shows the step-by-step and has a plethora of different actions like simplifying, inverse, and line.
Answer:
Brianna is right. The quotient is in the hundreds place ,because the first digit is 2 spaces to the left from the comma/period ,thus we know it's a hundred
1/4

1/13
C.
7/52
D.
17/52
About 8 sixth graders should be chosen.
Direct proportion is a type of proportionality relationship. For direct proportion, as one value increases, so does the other value and conversely, as one value decreases, so does the other value.
Given that, A population of middle school students contains 160 sixth graders, 180 seventh graders, and 140 eighth graders. Nine seventh graders were part of a random sample of the population chosen to participate in a survey.
We know they are in direct proportion,
Number of sixth graders students = 160
Number of seventh graders students = 180
Number of eighth graders students = 140
If 9 seventh graders were part of a random sample of the population chosen to participate in a survey.
Let the number of sixth graders should be chosen to be 'x'.
Since, there will be direct proportion.
180/9 = 160/x
20 = 160/x
x = 160/20
x = 8
Hence, About 8 sixth graders should be chosen.
