f(x) = -x² + 3
f(-2) = -(-2)² + 3 = -4 + 3 = -1
Answer → f(-2) = -1
Both are correct they just chose a different variable to solve for first. they will both get correct answers if they do the rest correctly.
Answer:
x=−6±3√5
Step-by-step explanation:
Answer:
She spent 5 hours mowing lawns.
Step-by-step explanation:
To solve, we will just use some algebra
8h + 20 = 60 | Subtract 20 from both sides
8h = 40 | Divide both sides by 8
h = 5
We can confirm this by plugging it back into the original formula.
8(5) + 20 = 60
40 + 20 = 60
60 = 60
Answer:
<CBA = <CDA
Step-by-step explanation:
Using <CBA = <CDA and Base angle theorem, you can say that AB = AD.
Now you have <CBA = <CDA, AB = AD, and CB = CD. These prove SAS.
