Answer:
Answer B - y=[x]+7
Step-by-step explanation:
A normal [x] function has a slope of one, a y intercept of 0, and all the other basic values.
7 changes this.
Looking at the graph, we see that the y intercept is now 7.
How can this be? x was added to by 7.
If it was subtracted, it would be -7, not postive 7.
So the answer is y=[x]+7
Hope this helps!
First cake requires x cups of flour.
Second cake: x + 1/2
Third cake: 2x
2 pound bag has 8 1/2 cups and it's exactly what Carly needs, so we can write it down as:
8 1/2 = x + x + 1/2 + 2x
8 1/2 = 2x + 1/2 + 2x
8 1/2 = 4x + 1/2 / - 1/2 (both sides)
8 = 4x / ÷ 4 (both sides)
<u>x = 2</u>
Doublecheck:
2 + 2 + 1/2 + 2 * 2 =
= 2 + 2 + 1/2 + 4 =
= 4 + 1/2 + 4 =
= 8 + 1/2 =
= 8 1/2
It's the same, so it must be correct ;)
Answer: Carly needs 2 cups of flour for each cake.
Hi.
If I had to say, I think I would say that is True.
Sorry if I'm wrong, but I really think it's true...
Answer:
y = 67 degrees
x = 86 degrees
z = 94 degrees
Step-by-step explanation:
This is easy...
38 + 56 = x
94
180 - 94 = 86
86 + 38 + 56 = 180
so x = 86 degrees
___________________
180 - 86 = 94
z = 94
___________________
94 + 19 = 113
180 - 113 = 67
67 + 94 + 19 = 180
so y = 67 degrees
