Answer:
Step-by-step explanation:
<u>Method 1:</u>
$300 on school supplies
1/10 on notebooks
As you're finding how much is left:
10/10-1/10=9/10
Convert 9/10 into a decimal
9/10=0.9
300*0.9=$270
OR
<u>Method 2: </u>
1/10=0.1
300*0.1=$30
Take away 30 from $300
$300-30=$270
By using either method, You would still have $270 left.
How this helps!!!
Have a nice day :)
Answer:
0.3 + 0.6 + 0.9 + 0.2 + 0.4 = 2.4
Hope this helps!
1) First one is a line f(x)=2x+1. It has y-int. (0,1), and second point, for example, (1,3)
2 points for line (0,1) and (1,3)2) Second one is a parabola g(x)=x²+2x-8.
In the vertex form it looks like
g(x) =x²+2x+1-1-8=(x+1)²-9
g(x)=(x+1)²-9 - parabola in the vertex form. Vertex is (-1,-9)Another point of the parabola can be found from the equation g(x)=x²+2x-8.
It is y-int. x=0, g(0)=-8, so
point on the parabola is (0,-8)For parabola Vertex (-1,-9) and point (0,-8)3) Solutions are (-3,-5) and (3,7).
