Answer:
The sum of 16 2/3 and 1/4 is 16 11/12
Step-by-step explanation:
(x-2)(x+10)=13
x^2 + 10x - 2x - 20 = 13
x^2 + 8x - 20 - 13 = 0
x ^2 + 8x - 33 = 0
(x + 11) (x - 3) = 0
x + 11 = 0
x = -11
x - 3 = 0
x = 3
The answer is clearly x = 3.
Choice a.
You multiply 5 x 3 Bc you multiplied the left side by 3. Hope this helps
Answer:
The range is -6, 4 , 12.
Step-by-step explanation:
If the domain is -4,0,5, x can only be -4 or 0 or 5.
Substitute each of these x-values into the equation 12x+6y=24. Then isolate to find the possible values of x.
Sub x for -4
12x+6y=24
12(-4)+6y=24
-48+6y=24
6y = 72
y = 12
Sub x for 0
12x+6y=24
12(0)+6y=24
6y = 24
y = 4
Sub x for 5
12x+6y=24
12(5)+6y=24
60 + 6y = 24
6y = -36
y = -6
The possible values of y are -6, 4 ,12 which is the range.
In set notation: R = {y|y=-6,4,12}
