F(x) = 5(-3x) ^2 - (-3x) + 1
f(x) = -8x ^2 + 3x + 1
f(x) = -8x ^3 + 3x
Answer:
25
Step-by-step explanation:
5 to the power of 5 is 3125.
because you do 5x5x5x5
then you do 5x5x5 which is 125
3125/125 = 25
Answer:
B- x= 10
Step-by-step explanation:
40x=400 -> 40 x 10= 400
-7x + 12 is not an equiv. expression because one of the - signs in the original expression has been changed to +.
Answer: 8) 42°, 65°, 115° 9) 1.5, 2
Step-by-step explanation:
8) Right off the bat I know that the measure adjacent to 157° is
23°. With both numbers inside the triangle combined, we get
65° meaning the last number is 115 because that'll add up to 180°
9) Considering the smaller triangle has half the length of the bigger triangle
The length of the rest are half the size too.
EF = 1.5
DF = 2
