1) we have to calculate the increase of the cost of the jacket.
Increase of the cost of the jacket=new price - previous price
increase of the cost of the jacket=$87.75 - $75.00=$12.75
2)Now, we calculate the percentaje incresae of the costo of the jacket by the rule of three.
$75=100%
$75------------------100%
$12.75------------- x
x=($12.75 * 100%) / $75=17%
Answer: the percentage increase of the cost of the jacket is 17%
If so then add 6, then divide the 7 off the a
Answer:
y = 2,-6
Step-by-step explanation:
Linear functions are of the form y = mx + b.
each time the number changes in the x, the y increases by 2
Answer:
Step-by-step explanation:
y - 5 = 3⁄2(x + 6)
y - 5 = 3⁄2x + 9
+ 5 + 5
__________
y = 3⁄2x + 14
- 3⁄2x - 3⁄2x
________
−3⁄2x + y = 14 [We do not want mixed numbers\fractions in our standard equation, so multiply by the denominator to get rid of it.]
−2[−3⁄2x + y = 14]
