Answer:
x>-9
Step-by-step explanation:p
1.) Subtract 1 from both sides
-2/3x+1<7
-1<-1
= -2/3x < 6
2.) Multiple the 3 (denominator) in order to get rid of the fraction
3(-2/3x) < (6)3
= -6/3x < 18 (simplify the 6/3 into 2)
= -2x < 18
3.) Divide by -2 (when you divide with a negative number, your sin is going to switch, meaning it will turn into a '>' sign)
-2x / -2 < 18/-2
= x > -9
*ALSO*
If you want to graph it on a number line, it would look something like the picture above. (the circle is open because it doesn't have the line underneath. You're symbol also indicates which way you shade!! < = left .....> = right.....think of them like arrows :) )
The function that represents how much you would pay is:
p(x) = (x - $5)*0.9
<h3>
How to find the function?</h3>
Let's say that the cost of the repair is x.
First, we apply the coupon, so we discount $5 for the cost.
x - $5.
Then we apply another discount of the 10%, this is written as:
(x - $5)*(1 - 10%/100%)
(x - $5)*(1 - 0.1)
(x - $5)*0.9
Then the function that represents how much you would pay is:
p(x) = (x - $5)*0.9

Answer:
a = -5/3
Step-by-step explanation:
3/a × -4 = 20
3a × -4/-4 = 20/-4
3a = -5
a = -5/3
Check:
3/(-5/3) × - 4 = 20
-5 × - 4 = 20
.25x54=13.5 163x1.25=203.75 13.5+203.75=217.25
