F(-1)
replace all x with -1
f(-1)=-3(-1)^2+2(-1)-7
f(-1)=-3(1)-2-7
f(-1)=-3-9
f(-1)=-12
Answer:
a) $340
b) $20
Step-by-step explanation:
a) in the summer (July and August) he earned 160 + 180 = $340
b) in July he earned 160 ÷ 8 = $ 20
I think the correct answer is B. It is the triangle case SSA that may have one, two, or zero solutions. This case can have either number of solutions but it depends on the sides of the triangle given. Having one solution can be all of the cases except SSS, having 2 solutions can only be applied to SSA.
Answer:
<u>x = 36</u>
Here's how I got that:
<em> - Group like terms -</em>
x - 2 + 2x + 4 + 2x - 2 = 180
↓
5x - 2 + 4 - 2 = 180
↓
5x = 180
<em> - Divide both sides by 5 - </em>
<em> </em> 5x/5 = 180/5
↓
<em> </em><u><em>x </em></u><u>= 36</u>
<em>~ That's all folks ~</em>
