Answer:
D
Step-by-step explanation:
simple : when we have a point defined as (1, 4), it means x = 1, y = 4.
and since the point is on the graph of a function/equation it means that when we use x = 1 and calculate the equation, we get 4 as result (= y). so yes, that means that both sides of the "=" sign are indeed equal for this pair of values, which makes the equation true.
but there will be usually many other pairs that do that too.
Answer:
Step-by-step explanation:
Read the problem carefully and figure out where it says plus and where it says per. Per implies multiplication. Plus is addition.
220+0.15x
To solve, plug in 355 for the answer and back solve for x.
7.50/ h because 15 is over 2 and h is 1 and since the bottom is half the top is half therefore it is 7.50 over h
Gas for lawn mower ... $2.25
mowing neighbor's yard ... $15.00
Julia's profit ... x
<span>We would like to know what is the value of the x.
x = $15.00 - $2.25 = $12.75
Result: Julia's profit is $12.75.

Depends on the question but you generally must use a variety of operations to isolate the variable by itself on one side of the equation
