Write an equation in slope-intercept form that describes the line through the points (-2,6) and (3, 1).
vladimir1956 [14]

Answer:

y=-x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(1-6)/(3-(-2))

m=-5/(3+2)

m=-5/5

m=-1

y-y1=m(x-x1)

y-6=-1(x-(-2))

y-6=-(x+2)

y-6=-x-2

y=-x-2+6

y=-x+4

Jaidee spent half of her weekly allowance on clothes. To earn more money her parents let her wash a dog for $9. What is her week
dolphi86 [110]

Answer:

14

Step-by-step explanation:

Firstly, we need to subtract the amount she earned from walking the dog ($9.00) from the end total ($16.00). This leaves us with $7.00.

Since she spent exactly<em> </em><em>half</em> of her weekly allowance, we must multiply the remaining $7.00 by 2. This leaves us with our final answer of $14.00.

Boxes of sticky hands popsicles are 4.50. The supermarket is offering a 30% off coupon. What is the price with the coupon?
ArbitrLikvidat [17]
Included in your weekly circular should be free coupons, so coupons are free (disregarding the price you have to pay to live around the area)


if you want to know how much discount the coupon give you then

4.5*3/10=1.35
takes off $1.35

proportion method

30/100=x/4.5
3/10=x/4.5
cross multiply or ties both sides by 10*4.5
3*4.5=10x
13.5=10x
divide both sides by 10
1.35=x


discount of $1.35 (coupon saves you $1.35)
