Answer:
A.
Step-by-step explanation:
It has a negative slope, so B and C are eliminated. The graph also has a solid line instead of a dashed line. This means D is eliminated because it is only greater than. If the graph had a dashed line, then D would be correct, but it does not.
Answer:
-15
Step-by-step explanation:
-3(-4-5x)= -18
12+15x= -18-12
15x= -30
x= -30÷15
x= -15
Answer:
y = 2x +1
Step-by-step explanation:
y=kx+1
Substitute the point into the equation
3 = k(1) + 1
3 = k+1
Subtract 1 from each side
3-1 = k
2 = k
y = 2x +1
The slope is 2 and the y intercept is 1
The correct question is
<span>Michael sold 2/3 of his CDs and purchased 16 more. If Michael has 25 CDs now, how many CDs did he have to begin with?
Let
x--------------> numbers of CDs Michael have to begin
if Michael sold (2/3)x-----------> </span><span>are pending to sell (1/3)x
we know that
(1/3)x+16=25--------> </span>(1/3)x=25-16-------> (1/3)x=9---------> x=27
the answer is 27 CDs
Answer:

Step-by-step explanation:
We start by adding
to both sides, giving
, which after simplifying gives
.
We then add
to both sides, giving
, which after simplifying gives
.
We can then divide both sides by
, giving
, which after simplifying gives
, or
. So, x is 5.
