-8 > -5x + 2 > -38...subtract 2
-8 - 2 > -5x + 2 - 2 > -38 - 2
-10 > -5x > -40 ... now divide by -5, and change inequality sign
-10/-5 < (-5/-5)x < -40/-5
2 < x < 8
The answer for 4 is 17.5 I’m pretty sure
Answer:
the third one (bottom left)
Step-by-step explanation:
all the others have at least one x value with multiple possible y values.
but for a function, there must be exactly 1 y value for each defined x value.
Order of operations: the rules of which calculation comes first in an expression.
They are: PEMDAS
<span><span>Do everything inside parentheses first: ()
</span><span>then do exponents: x2
</span><span>then do multiplies and divides from left to right
</span><span>lastly do the adds and subtracts from left to right</span></span>
First you gotta remove all parentheses by multiplying the factors next remove all grouping if the terms are containing exponents then you combine all terms and lastly you combine the constants
