When you divide 7/8 by 1/5, which is equal to 7/8 • 5/1 which you get 35/8 or 4 3/8, answer is C
Answer:
Table 1
Step-by-step explanation:
Check Table 1:-
x = -4 gives y = (-4)^2 + 4(-4) = 0
x = -2 gives y = (-2)^2 - 2(-2) = -4
x = 0 gives 0 + 0 = 0
x = 1 gives 1^2 + 4 = 5
That's the one!
Answer: x = -4, x = 5
Step-by-step explanation:
You can use the substitution method for this problem.
y = 
+ 2x, but y also = 3x +20.
Because of this, you can determine that +2x = 3x + 20 because they are both equal to the same thing, y.
Solve the quadratic equation you got from substitution:
+ 2x = 3x + 20
-x = 20
-x -20 = 0
You can factor this equation:
(x+4)(x-5) = 0
x = -4, x = 5
I’m sure the answer is B.
In mathematics, the reciprocal, or multiplicative inverse, of a number x is the number which, when multiplied by x, yields 1. It is denoted 1/x or x-1.
