The values that make the denominator zero are not in the domain.
x²- 4x - 12 = 0
(x - 6)(x + 2) = 0
Answer: 6, -2
Answer:
-3
Step-by-step explanation:
This is just another word for slope
y-y over x-x
y: 4-1 =3
x: -2 - (-1)= -1
so 3/-1 which reduces to -3
Answer:
C: 5%
Step-by-step explanation:
175 out of 3500 = 175/3500
175/3500 = 1/20
1/20 = 0.05
0.05 = 5%
Answer:
B. (2, 7)
Step-by-step explanation:
(1) 5x + 3y = 31
(2) 2x + 3y = 25 Subtract (2) from (1)
3x = 6 Divide each side by 3
x = 2 Substitute in (2)
=====
4 + 3y = 25 Subtract 4 from each side
3y = 21 Divide each side by 3
y = 7
The solution is (2, 7).
=====
<em>Check:
</em>
(1) 5×2 + 3×7 = 31
10 + 21 = 31
31 = 31
(2) 2×2 + 3×7 = 25
4 + 21 = 25
25 = 25
Answer:
169
Step-by-step explanation:
divided = divisior * quotient + remainder
so d = 13*13
= 169
