Answer:
- changes by 120 for each copy
- is 1800 if none are sold
Step-by-step explanation:
Let's look at the second question first.
x is the number of copies Chau sells. If he doesn't sell any copies, then x = 0. To find Chau's pay, we use x=0 in the equation, and solve for y.
120×0 +1800 = y
0 +1800 = y
1800 = y
Chau's pay when he sells no copies is $1800.
__
If Chau sells 1 copy, then his pay is ...
120×1 +1800 = y = 1920 . . . . . . . use the equation with x = 1
The increase in Chau's pay is 1920 -1800 = 120.
Chau's pay changes by $120 for each copy he sells.
Rearrange equation to get
6x>12 so
x>2
Answer:
x ≥ −42
Step-by-step explanation:
Let's solve your inequality step-by-step.
x/7≥−6
Step 1: Simplify both sides of the inequality.
Step 2: Multiply both sides by 7.
x ≥ −42
Answer:
The answer is "SAS".
Step-by-step explanation:
In this question we assume two angle is given that are:
That's why SAS rule is correct.
One solution BECAUSE they only intersect once!
Many solutions means they are on top of each other
No solutions means they are parallel to each other!
