Answer:
c. f(x) = (x + 4)(x - 1)
Step-by-step explanation:
Since you're familiar with the product of two binomials:
(x +a)(x +b) = x² + (a+b)x + ab
you know that the constants in the binomial factors must ...
- have a product of -4
- have a sum of +3
__
All of the choices except B have binomial constants that have a product of -4.
In order, the sums of the remaining choices are ...
A: 1-4 = -3
C: 4-1 = 3 . . . . this is the correct choice
D: -2+2 = 0
Answer:
x = 1, y = 3
Step-by-step explanation:
Use the y and substitute it into the 2nd equation. Solve for x. Then use that answer to solve for y.
7.5 i believe. not very good at math tho lol
Answer:
-4 =x
Step-by-step explanation:
ƒ(x) = 9x + 54
Let f(x) = 18
18 = 9x+54
Subtract 54 from each side
18-54 = 9x + 54-54
-36 = 9x
Divide each side by 9
-36/9 = 9x/9
-4 =x
Complementary is when angles equal 90 degrees.
supplementary is when angles equal 180 degrees.
a)
supp:145 degrees
comp:55 degrees
b)
supp:23 degrees
comp: none
c)
supp:159 degrees
comp:69 degrees
