step 1
(x - 4) • (x + 5) = 0
STEP
:
A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
Solving a Single Variable Equation:
2.2 Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4
Solving a Single Variable Equation:
2.3 Solve : x+5 = 0
Subtract 5 from both sides of the equation :
x = -5
.
Answer:
c=20
Step-by-step explanation:
200=10c
200/10=c
20=c
h(x)= -kx + 14
18 = -k*2 + 14 since x=2
18 = -2k +14
subtract 14 from each side
4 = -2k
divide by -2
-2 =k
