Answer: 15 squash, 5 pumpkins; 15 squash, 10 pumpkins; 20 squash, 5 pumpkins.
Step-by-step explanation:
Then graph the system of inequalities: 3.5x + 5.59y (less than or equal to) 117; x + y > 10.
The first inequality is saying the cost of x squash and y pumpkins should total no more than $117.
The second inequality states x squash and y pumpkins should add up to more than 10.
Let:
x= quarters
y= dimes
x+y=67
and
.25x+.10y=12.40
x=67-y
.25(67-y)+.10y=12.40
16.75-.25y+10y=12.40
16.75-.15y=12.40
Lets rearrange this:
-.15y+16.75=12.40
-16.75 -16.75
-.15y=-4.35
the negatives cancel out
.<u>15y</u>=<u>4.35
</u>.15<em /><em> <u /></em>.15
y=29
Back to the original x=67-y
x=67-29
x=38
So,
x=38
y=29
<em />
Multiply both sides of the inequality by 2
x-10>-14
move constant to the right side and change its sign
x>-14+10
calculate the sum
x>-4
answer is x>-4
56 + 8x
Area of Rectangle = Length x Width
Area of Rectangle = 8(7 + x)
Answer:
Graph 2 is the cubic equation.
Step-by-step explanation:
We have been given the two graphs
So, we will conclude the function by end behavior
The cubic function enters from the left downwards and exists the graph from the right.
Cubic function will have 3 zeroes being of 3rd degree
And since the second function cuts the graph at three points
Hence, second graph is the cubic equation.
Zeroes are: -3 ,0 and 3.
