X=10 because you have to divide 481.65 by 39 which is 12.35, then subtract 2.35 and then you get 10=x

<span>Step 2 :</span>Pulling out like terms :
<span> 2.1 </span> Pull out like factors :
5x - 35y + 50 = 5 • (x - 7y + 10)
Final result :<span> x - 7y + 10</span>
Answer:
Janice needs 1$ more.
Step-by-step explanation:
Multiply both price rates by 5.
(.80x5)+(1.40x5)
(4)+(7)
Add to find the total cost.
11$
Subtract the cost from the budget.
11-10=-1$
Janice needs 1$ more.
Answer:
The height of the highest point of the arch is 3 feet.
Step-by-step explanation:
The complete question is:
A dome tent’s arch is modeled by y= -0.18(x-6)(x+6) where x and y are measured in feet. To the nearest foot, what is the height of the highest point of the arch.
Solution:
The expression provided is:
The equation is of a parabolic arch.
The general equation of a parabolic arch is:
So,
a = -0.18
b = 6.48
c = 0
Highest point of the parabolic arch is the vertex of the parabolic equation if <em>a</em> < 0
.
As <em>a</em> = -0.18 < 0, the ordinate of vertex of equation will give the height of highest point of arch.
For a parabola the abscissa of vertex is given as follows:
⇒
Compute the value of <em>y</em> as follows:
Thus, the height of the highest point of the arch is 3 feet.
