Factor left sides of the equation
(x-1)(x+9) = 0
Set factor equal to 0
x-1 = 0 or x+9 = 0
x= 1 or x= -9
I hope that's help and have sweet dream !
Answer:
Step-by-step explanation:
Since the sale price is always less than the original, we take the original and subtract from it the percent off to give us the sale price. Putting that into equation form:
s = r - .10r
which says, in words, that the sale price is equal to the regular price minus 10% of the regular price.
Answer:
4/5x(v-7)=2
multiply both sides by 5/4, the reciprocal of 4/5
v-7=2x(5/4)
Express 2x(5/4) as a single fraction
v-7=<u>2</u><u>x</u><u>5</u>
4
Multiply 2 and 5
v-7=<u>1</u><u>0</u>
4
Reduce the fraction 10/4 to the lowest by extracting and cancelling 2
v-7=<u>5</u>
2
Add 7 to both sides
v=<u>5</u>+7
2
Covert fraction to 14/2
v=5/2+14/2
Since 5/2 and 14/2 have the same denominator, add them by adding their numerators
v=<u>5</u><u>+</u><u>1</u><u>4</u>
2
Add 5 and 14 together
v=<u>1</u><u>9</u>
2
Evaluate f(9) + f(5)= 14f If I didn't answer Your Question fully than tell me please!
