Answer:
x = -1
Step-by-step explanation:
The usual approach to these is to square the radicals until they are gone.
Each time the equation is squared, the possibility of an extraneous root is introduced. Here, x=3 is extraneous: it does not satisfy the original equation.
The solution is x = -1.
_____
Using a graphing calculator to solve the original equation can avoid extraneous solutions. The attachment shows only the solution x = -1. Rather than use f(x) = 2, we have rewritten the equation to f(x)-2 = 0. The graphing calculator is really good at showing the function values at the x-intercepts.
Answer:
Yes
Step-by-step explanation:
Because 35 * 1 is 35 and 35 * 2 is 70
Answer:
She would be paying $2,622 total.
Step-by-step explanation:
1. To get how much she'd be paying for 24 months, all you have to do is multiply 24 times 95.
2. To get the down payment you had to ask yourself what's 15% of 2,280. 15% of 2280 is 342.
3. Add those together and you'd get the total payment.
Simple.
Oh and gimme Brainliest if it's correct.
Answer:
you dint put up the pictures so not sure
Step-by-step explanation:
The graph of the function is a parabola.
The nose comes down as far as y=4 but no farther.
That happens when (x - 2)² = 0 , and THAT happens when x = 2 .
