Hey!
So if you mean find h(-8), then you would just plug in -8 for t!
-2(-8+5)^2 + 4 = h(t)
Don't forget about PEMDAS!
So first we are going to solve the parenthesis.
-2(-3)^2 + 4 = h(t)
now the exponent
-2(9) + 4 = h(t)
you might be wonder why it's 9 and not -9, that is because since the -3 is in parenthesis, the - is included and -3 times -3 is 9. If the - was not included in the parenthesis and was on the outside then it would be -9.
Let's carry on.
Now multiply
-18 + 4 = h(t)
Now add and get your answer
-14 = h(8)
Your answer is -14!
Hope this helps!
Answer:
b) y = f(x) = -3x+4
Step-by-step explanation:
<u><em>Explanation</em></u>
Given that the equation 9x+3y =12
Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form
y = f(x)
3 y = 12 - 9x
y = -3x+4
The function represented by y = -3x+4
Answer:
The ratio for crayons to school supplies is 8:12
1. slope= 1 work- 6-5 1
--- = - = 1
-2-3 1
4. slope= -3 work- -3- -3=-6 -3
---------- = ---- = -3
6-4= 2 1
