The answer would be 413,000,000 and 4,000
To put this into simpler terms, well simplier for me anyways, Emma is dividing 9 inches of paper into 2/5, or .4, inches of paper.
That being said, we now just need to divide 9 by 2/5 or .4
We get 22.5
So Emma will be able to make 22 strips since we can't have half a strip. (Well, we could, but it would be small than what we need)
Any questions?
Range is the value of y
f(x)=-x²+5
when x=-1, f(x)=-(-1)²+5=4
when x=2, f(x)=-(2)²+5=1
so 1<y≤4
the second piece: f(x)=2x-3
when x=2, f(x)=2(2)-3=1
when x=5, f(x)=2(5)-3=7
so 1≤y<7
union of the two parts of y: 1≤y<7
[1,7) is the answer.
Step-by-step explanation:
- y=(4×2)+5
y=8+5
<u>Y=1</u><u>3</u>
2. 4=4x+5
4x=4-5
<u>4</u><u>x</u>= <u>-1</u>
4. 4
x= <u>-1</u>
4
