Answer:
x=4/3 , x=-5/2
Step-by-step explanation:
6x^2 +7x=20
6x^2+7x-20=0
(3x−4)(2x+5)
3x-4=0 , 2x+5=0
3x=4 , 2x=-5
x=4/3 , x=-5/2
Answer:
144
Step-by-step explanation:
The equation to find c is:
So put -24 into b:
Which simplifies to:
144
So if you want to test this:
x^2 - 24x + 144
is
(x-12)^2
yeah i need this one tooAnswer:
Step-by-step explanation:
Add the two deposited amounts to the first total of 5170 to give you 6246. you know they have an equal amount of money, so divide that by 2 to give the amount for each person (3123). then solve from there using what you know. x will be mr and y will be mrs
x+450=3123 subtract 450 and you have 2673
y+626=3123 subtract 626 and you have 2497
so Mr had 2673 and Mrs had 2497
Domain: x
Range: f(x) {or y}
An example of a point for this equation would be (1 ,2) where 1 would be the domain (or x) and the range (or y) would be 2. Hope this helps :)
