Please help me I need to get this done!!!
alukav5142 [94]

Answer:

y=-3x+4

Step-by-step explanation:

The question is asking for the equation in slope-intercept form. This is y=mx+b where m is the slope and b is the y-intercept.

The slope can be found by counting the units in between two points on the graph. Remember that slope is rise over run or y/x. Two points on the graph are (2,-2) and (1,1). The y is increasing by 3 while x is decreasing by 1. This means the slope is -3.

The y-intercept is where the line intersects with the y-axis. In this case, that point is (0,4). Therefore, b=4.

The final answer is y=-3x+4.

Joanie decides to buy matching sweaters for herself and her 3 sisters. The regular price of the sweaters is $37. Joanie says if
Roman55 [17]

Answer:

Yes, it is possible if the sweaters on sale are $7.40 each.

Step-by-step explanation:

The sweaters each cost $37. To purchase all four (for herself and 3 sisters) without a sale would be 4(37)= $148.

40% off the regular price would be 0.40(148)= $59.20 savings. She would spend 148-59.2= $88.80.

Is it possible to buy two regular price sweaters and two on sale for $88.80?

2(37)=$74. If we subtract from the sales total, 88.80-74=14.80. This means the two sweaters on sale must each be $7.40. It is possible to save 40%.

Answer:

\/

Step-by-step explanation:

▪Picture 1. x = 28

\frac{x}{42}  =  \frac{10 + x}{57} \\ 42(10 + x) = 57x \\ 420 + 42x = 57x \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: - 42x =  - 42x}{ \frac{420}{15}  =  \frac{15x}{15} }   \\  \\ 28 = x
