Answer:

Step-by-step explanation:
we are given a quadratic function

we want to figure out the minimum value of the function
to do so we need to figure out the minimum value of x in the case we can consider the following formula:

the given function is in the standard form i.e

so we acquire:
thus substitute:

simplify multiplication:

simply division:

plug in the value of minimum x to the given function:

simplify square:

simplify multiplication:

simplify:

hence,
the minimum value of the function is -155
Answer:
x = 12, y = 17
Step-by-step explanation:
x+5 = 2x-7
x = 12
y = x+5 = 17
Answer: D
You can still simplify 9/15
9/15 can be divided by 3, thus the answer will be 3/5.
1. u must simplify 3^2 first because the order of operations states that u have to do exponents before subtraction.
2. 12 - 3^2 = 81......she subtracted the 3 first....12 - 3^2 = 9^2 = 81...which is an incorrect answer
3. u do not divide before simplifying 3^2.....order of operations states that u have to do exponents before division
4. no.....(12 - 3)^2 ......order of operations states that u do parenthesis before exponents...so (12 - 3)^2 = 9^2 = 81
