Answer:
The correct factored form is (x -2)(x - 5)
Step-by-step explanation:
When looking for the numbers to go in the parenthesis, find numbers that multiply to the final term and add up to the middle term. To find these, list out the factors of 10.
1 * 10
-1 * -10
2 * 5
-2 * -5
As you can see, -2 and -5 add up to -7. So we select these to go in the parenthesis with x.
(x - 2)(x - 5)
$43.8, do 7.3 (if that’s how long it was) times $6, giving you 43.8
Answer:
b and c
Step-by-step explanation:
Answer:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
Step-by-step explanation:
Given
Required
Create a table that represents this scenario
Because x represents time, x can not be negative. So, the domain of x is:
Assume
Assume x = 4
Assume x = 6
Hence, the table is:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
Get the y by itself
-2y= -3x + 1
Divide -2 to everything
y= 3/2x - 1/2
Other equation (get y by itself)
-6y= -9x + 3
y=3/2x - 1/2
Use substitution
3/2x-1/2=3/2-1/2
0=0
All real numbers (any value of x makes the equation true)
