Susie wants to buy a snowboard that cost $530. she has already saved $98 for it. she makes $72 a week babysitting. which inequality gives the minimum number of weeks, w, susie needs to babysit to have enough money to purchase this snowboard.

98+72*x>530

Step-by-step explanation:

u then need to calculate x, which should be fine

Your equation would be 530 = 72x + 98

The answer to your equation would be, she would need to work 6 weeks.

Step-by-step explanation:

530 = 72x + 98

530 - 98 = 432

432 / 72 = 6

How I got the equation:

First, the ending amount will be 530 so that will be our answer.

530 =

72 is how much she makes a week so x would represent the amount of weeks.

530 = 72x

Then she already has 98 so that would be added to the end.

530 = 72x + 98

Hope this helps!

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

step-by-step explanation: yes
