Factor the equation. Remember the value should add to the b value and multiply to the c value.
x^2-x-12= 0
(x-4)(x+3)=0
Use the zero product property to find roots
x-4=0
x=4
x+3=0
x=-3
Final answer: x=-3, x=4
Set x as adult tickets.
Set y as children's tickets.
x + y = 15
30x + 20y = 270
Solve for x in the first equation.
x + y = 15
x = 15 - y
Plug this into the second equation.
30x + 20y = 270
30(15 - y) + 20y = 270
450 - 30y + 20y = 270
450 - 10y = 270
-10y = -180
y = 18
If there is 18 childrens tickets, there should be -3 adult tickets.
This is impossible, and this impossible answer occured because the question is written wrong.
There are a total of 15 tickets
The smallest costing ticket is the childrens ticket, which costs 20$.
If he only bought children tickets, this would be 20x15 which is 300$.
300$ is over 270$, which makes the question impossible.
Answer:
Step-by-step explanation:
pi*r^2=area
1*1=1
1*3.14=3.14
the area is pi itself
Company fixed cost = $10 million = $10,000,000
Variable cost per pair = $5
Company charges each pair = $15
Hence the company makes $10 profit per pair
regardless the company fixed cost and only considering the variable cost.
Let subtract the variable cost per pair from the
company charging each pair = 15 - 5 = $10
Thus the company now makes $10 per pair, and it has
to sell 1,000,000 pairs of gloves to reach the break-even point. The break-even
point refers to the point where total cost and revenue are equal.
<span>Thus for 1,000,000 pairs, the company total earning =
10 x 1,000,000 = $10,000,000 = $10 million </span>
Y=-4x+16 is slope intercept form. I hope this helped
