Answer:

y = -2x + 9

Step-by-step explanation:

Using the slope intercept equation y=mx+b, we can see that the slope of the line parallel to y = -2x + 7 is -2.

m = -2

Use the point slope formula y - y1 = m(x - x1) to find the line that runs through (4,1)

y - 1 = -2(x - 4)

Simplify

y - 1 = -2x + 8

y = -2x + 9

You can check your answer by putting in the point and seeing if the equaiton is true

1 = -2(4) + 9

1 = -8 + 9

1 = 1

True

Tammy knits blanket and scarves. On the first day of a craft fair, she sells 2 blankets and 5 scarves for $104
omeli [17]

Answer:

Cost of Blanket = 32

Step-by-step explanation:

Let the cost of a blanket be = b , cost of a scarf be = s. Blanket price x Blanket Quantity & Scarf Price x Scarf Quantity sum up to be total sales.

So, Day 1 : 2b + 5s = 104 (i)  , Day 2 : 3b + 4s = 128 (ii)

Solving equations : Multiplying (i) by 3 , & (ii) by 2 , we get

6b  +  15s    =   312 ,

(-)6b + (-)8s =  (-)256

By elimination method, 15s - 8s = 312 - 256 → 7s = 56 → s = 56 / 7 = 8 .

Putting s value in any equation i], 2b + 5 (8) = 104 → 2b + 40 = 104 → 2b = 104 - 40 = 64 → b = 64 / 2 = 32
