Answer:
This answer is A
A. X= -1
Step-by-step explanation:
-1 is equal to-1
Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
First, find slope using the given coordinates. Formula for slope: y₁ - y₂ / x₁ - x₂.
Our coordinates are (-2, 5) and (2, -7). Plug them in and simplify.
5 - (-7) / -2 - 2
5 + 7 / -4
12/-4
-3
The slope is -3. The equation becomes y = -3x + b.
To find b, plug an (x, y) coordinate on the line in for x and y in the equation and solve. I'll use (-2, 5)
y = -3x + b
5 = -3(-2) + b
5 = 6 + b
-1 = b
The y-intercept is (0, -1). The equation can now be completed!

y = -3x - 1
Answer:
There is none
Step-by-step explanation:
The fact is that how Sheila wanted to buy a picture frame and spend the rest of her money on her teachers. If you do not know the cost of the picture frame you can not solve it. However, if she were to just spend her money on gift cards she could be able to buy 6 gift cards and have five dollars left over, but is not the case. It is like buying candy with five dollars when it actually costs 10 dollars.
7/8 of a yard is 3*7/8 or 21/8 feet.
Divide the number of feet of fabric by the number of scarves she can make
156/(21/8)= 59.42 scarves.
But she cant make half a scarf, so she can only make 59 scarves,
Hope this helps.
