2 answers:
Answer:
41
Step-by-step explanation:
b^2 -2ac
Let a=4 b=3 c=-4
( 3)^2 -2 (4) (-4)
Exponents first
9 - 2 (4) (-4)
Multiply
9 + 32
41
Answer:
41
Step-by-step explanation:
b^2 - 2ac plug in the values
3^2 -2(4)(-4) start with the exponent (remember PEMDAS)
9 -2(4)(-4) start multiplying from left to right
9 -8(-4) multiply
9 + 32 add
41 that's your answer :)

1/4a + 1/3a +8 =22
1st step add like terms:
1/4a +1/3a = 3/12a +4/12a = 7/12a
7/12a +8 =22
2nd step subtract 8 from each side:
7/12a = 14
3rd step divide both sides by 7/12 to get a:
a = 14 / 7/12
a = 24
It’s only a vertical angle

Answer: y = 
<u>Step-by-step explanation:</u>
y = ax² ; where a represents the vertical stretch
a reflection across the x-axis is represented by making the a-value negative.
