We have that
x/(x+5)=(x-2)/(x+1)---------- > x*(x+1)=(x-2)*(x+5)- -----> x²+x=x²+5x-2x-10
x²+x=x²+5x-2x-10------- > 2x=10
x=5
the answer is x=5
Answer:
The % of cost to revenue of sponsorship is 17.87%
Step-by-step explanation:
Given:
Amount for sponsorship =310000$
Administrative cost=47,000$
To Find:
What are the cost as a percentage of sponsorship revenue.
Solution:
Administrative cost is expenses incurred to something to buy for a department.
It is losing amount to buy something.
Sponsorship is the support given to baseball team which 310000$
Total Cost after expenses will given by ,
=Sponsorship -administrative cost
=310000-47000
=263000$
Sponsorship revenue is the cost given to third party after commission
So percentage of cost to sponsorship revenue
=(47000/263000)*100
=17.87%
Answer:
The answer to your question is k = -3233
Step-by-step explanation:
Data
x₁, x₂ are the roots
Equation l x² - 8x + k = 0
Equation ll 3x₁ + 4x₂ = 29
k = ?
Process
1.- Write another equation
x₁ + x₂ = - 8
2.- Solve the system of equations by elimination
3x₁ + 4x₂ = 29 Equation l
x₁ + x₂ = -8 Equation ll
-Multiply equation ll by -3
3x₁ + 4x₂ = 29
-3x₁ - 3x₂ = 24
0 + x₂ = 53
-Find x₁
x₁ + 53 = -8
x₁ = -8 - 53
x₁ = -61
2.- Find k
(x₁)(x₂) = k
(53)(-61) = k
k = -3233
a) For there to be a y-intercept of 3, when x=0, y=3.
- A. y=(0+1)(0-3)=-3
- B. y=0²-9=-9
- C. y=3(0)(0-3)=0
- D. y=(0+1)(0+3)=3.
So, the answer is D
b) For there to be roots of 0 and 3, there has to be factors of x and (x-3).
- The only choice that satisfies this is C
