Answer:
It would be 2,000x+200
Step-by-step explanation:
okay it costs $200 to attend so that's a cost you are going to have to pay regardless. The $2,000 depends on how many cars you buy. So it would be 2,000 (times how ever many cars you buy) plus the $200.
Assuming there are only three colors on the spinner (black, red and white,) the probability of landing on white can be found by subtracting the probabilities for black and red from 1. This gets you 0.16, or one-sixth.
36 and 100 are both perfect squares
the factorization of x^2-y^2 is (x+y)(x-y)
substitute x^2 with 36x^2 and y^2 with 100y^2:
<span>36x^2-100y^2=
(6x+10y)(6x-10y) or
4(3x+5y)(3x-5y)</span>
The answer to that problem is A
To solve this you must replace x with -4 and y with 5 in the equation 7x + y² like so:
7 × (-4) + 5²
To solve this use PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
Exponent...
7 × (-4) + 5²
5² = 5 × 5 = 25
7 × (-4) + 25
Multiplication...
7 × (-4) + 25
7 × (-4) = -28
-28 + 25
Addition...
When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number (disregarding the signs). In this case the largest number is 28 and its sign is negative. Your answer will have a negative sign.
-28 + 25 = -3
-3
