Answer: What numbers do the first letter x second and letter y represent
Step-by-step explanation:
The answer is x plus or minus 5 minus square root 41 all over 4
Ok let’s solve it
5(x-2)^2-20=0
first let’s foil (x-2)
5(x^2-4x+4) -20=0
now distribute the 5
5x^2 -20x +20 -20 = 0
combine like terms
5x^2-20x=0
take the gcf
5x(x-4)=0
x=0, 4
solutions are (4,0) and (2, -20) because the original vertex form a(x-h)^2+k
Answer:
Let me try...
Step-by-step explanation:
let's combine like terms first to simplify the equation
we need to only combine the variables with the same variable.
3a+5a would make 8a
and 4b+10b would be 14b
but we cannot combine 8a and 14b
so the equation remains as 8a+14b
The first thing we should do is to multiply 50 and 13 3/4
13 3/4 is equivalent to 13.75 .
So, we then multiply
50 x 13.75 and we get 687.50.
so, $687.50 was the amount spent on the stock.
Now, lets find out how much they sold them for:
What we do is multiply 12 and 50
50 x 12 would be 600
We can find out the loss by subtracting
$687.50 - $600 and that gives us $ 87.50.
Therefore, $87.50 is your answer :)
