y = 40x − 25 and y = 35x − 5
(x = total games and y = amount earned)
Beth determined that at 135 games, the referee would earn the same salary for each conference game. Is she correct?
Yes, Beth is correct.
No. She did not find the correct intersection point.
No. She only estimated and did not find the exact values.

Daisy's Flowers sell a rose bouquet for $39.95 plus $2.95 for every rose. A competing florist sells a similar bouquet for $26.00 plus $4.50 for every rose. Find the number of roses that would make both florists' bouquets cost the same price.
Answers
Answer:
9 rosesStep-by-step explanation:
Step one:
given data
For Daisy's Flowers
the cost is $39.95
an additional $2.95 for every rose
let the number of rose be x
the linear model for the cost is
y=39.95+2.95x-----------1
Step two
For the competing florist
the cost is $26
an additional $4.5 for every rose
let the number of rose be x
the linear model for the cost is
y=26+4.5x------------2
Step three:
equating the two above equations to find the number of roses x
we have
39.95+2.95x=26+4.5x
solve for x
39.95-26=4.5x-2.95x
13.95=1.55x
divide both sides by 1.55
x=13.95/1.55
x=9
Hence the number of roses that would make both florists' bouquets cost the same price is 9 roses

Show that each of the following values for the given variable is a solution to the
given equation. Show the calculations that lead to your answer.
(a) 3x + 4 = 7
for x = 1
Answers
Part a)
Answer:
As the L.H.S = R.H.S, so [tex]x = 1[/tex] is the solution to the equation [tex]3x + 4 = 7[/tex]
Step-by-step explanation:
Given the equation
[tex]3x + 4 = 7[/tex]
solving the equation for x = 1
substituting the value of x = 1 in the equation
[tex]3\left(1\right)+\:4\:=\:7[/tex]
[tex]7=7[/tex]
As the L.H.S = R.H.S, so [tex]x = 1[/tex] is the solution to the equation [tex]3x + 4 = 7[/tex]
Part b)
Answer:
As the L.H.S = R.H.S, so [tex]x = 15[/tex] is the solution to the equation [tex]\frac{x-3}{2}=6[/tex]
Step-by-step explanation:
Given the equation
[tex]\frac{x-3}{2}=6[/tex]
solving the equation for x = 15
substituting the value of x = 15 in the equation
[tex]\frac{15-3}{2}=6[/tex]
[tex]\frac{12}{2}=6[/tex]
[tex]6=6[/tex]
As the L.H.S = R.H.S, so [tex]x = 15[/tex] is the solution to the equation [tex]\frac{x-3}{2}=6[/tex]
Part c)
Answer:
As the L.H.S = R.H.S, so x = -3 in the equation is the solution to the equation [tex]x^2=-2x+3[/tex]
Step-by-step explanation:
Given the equation
[tex]x^2=-2x+3[/tex]
solving the equation for x = -3
substituting the value of x = -3 in the equation
[tex]x^2=-2x+3[/tex]
[tex]\left(-3\right)^2=-2\left(-3\right)+3[/tex]
[tex]9 = 6 + 3[/tex]
[tex]9 = 9[/tex]
As the L.H.S = R.H.S, so x = -3 in the equation is the solution to the equation [tex]x^2=-2x+3[/tex]

1. A fish is 12 meters below the surface of the ocean. What is its elevation? meters 2. A sea bird is 28 meters above the surface of the ocean. What is its elevation? meters 3. If the bird is directly above the fish, how far apart are they? meters
Answers
Answer:
- 12 meters
28 meters
40 meters
Step-by-step explanation:
Given that:
A fish is 12 meters below the surface of the ocean. What is its elevation?
Position of fish = 12 meters below the surface = - 12 ;
Sea level = 0
Elevation = sea level + position
Elevation = 0 + (- 12)
= - 12 meters
2. A sea bird is 28 meters above the surface of the ocean. What is its elevation?
Position of bird = 28 meters below the surface = (28) ;
Sea level = 0
Elevation = sea level + position
Elevation = 0 + 28
= 28 meters
3. If the bird is directly above the fish, how far apart are they?
If bird is directly above the fish;
Distance between bird and fish :
Elevation of bird - elevation of fish
28 - (-12)
28 + 12
= 40 Meters
The mass of a baby elephant is 113 kg, and it walks at a constant velocity of 0.5 m/sec. What is the kinetic energy for the baby elephant?
Answers
Answer:
Step-by-step explanation:
K.E. = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]
So,
=1/2 x 113 x 0.5 x 0.5
=1/2 x 1/2 x 1/2 x 113 (Because, 0.5 = 1/2)
=1/8 x 113
= 14.125 J
Using the kinetic energy formula, the kinetic energy of the baby elephant is 14.125 joules
Given the Parameters :
Velocity, v = 0.5 m/secMass, m = 113 kgRecall :
Kinetic energy = 0.5mv²The kinetic energy of the baby elephant can be calculated thus :
Kinetic energy = 0.5 × 113 × 0.5² = 14.125 Joules
Therefore, the kinetic energy of the baby elephant is 14.125J

Zeros of a quadratic equation are -1 and 5.
Sum of zeros = -1 + 5 = 4
Product of zeros = (-1)(5) = -5
The quadratic equation will be :

Every month the library hosts a family movie night. This month, 50 people attended the movie night. This was two more than three-fourths of the total number of people who attended the movie night last month. Write and solve an equation to determine how many people attended last month's family movie night. Use x as the variable.
Answers
Answer:
64 people
Step-by-step explanation:
Let the number of people that attended the movie last month be represented by x.
Number of people who attended the movie this month = 50
[tex]\frac{3}{4}[/tex] of x + 2 = 50
[tex]\frac{3x}{4}[/tex] + 2 = 50
[tex]\frac{3x}{4}[/tex] = 50 - 2
[tex]\frac{3x}{4}[/tex] = 48
3x = 48 x 4
3x = 192
x = 64
The number of people that attended the movie last month was 64.

Paul says that (3.14 X 10^5) + (2.53 X 10^4) = 5.67 X 10^5. Is Paul correct? Explain.
PLEASE I NEED HELP WITH THIS ASAP
Answers
Paul is wrong as first he has to convert their powers to the same value with base 10.
What is scientific notation?We use the scientific notation of numbers to write very large numbers in compact form.
In the scientific form, we write a number in the form of base×10ⁿ.
Where 0 ≤ base < 10 and n can be any rational number.
Given, Paul says (3.14 X 10⁵) + (2.53 X 10⁴) = 5.67 X 10⁵. he is wrong to add bases they must have the same power of 10.
∴ (3.14 X 10⁵) + (2.53 X 10⁴).
= (31.4 X 10⁴) + (2.53 X 10⁴).
= 33.93 X 10⁴.
