Answer:
Barry: g(x) = 50 + 30x
Larry: f(x) = 90 + 20x
If Locksmith Larry charges $90 for a house call plus $20 per hour. Locksmith Barry charges $50 for a house call plus $30 per hour. Then f(x)=90+20x is one-variable equation for the charges of locksmith Larry
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Locksmith Larry charges $90 for a house call plus $20 per hour
f(x) represents this situation
f(x) equal to ninety plus twenty times of x
f(x)=90+20x
Locksmith Barry charges $50 for a house call plus $30 per hour
g(x) represents this situation
g(x) equal to fifty plus thirty times of x
g(x)=50+30x
Here x represents the number of hours
Hence f(x)=90+20x is the one-variable equation for the charges of locksmith Larry

One liter is approximately 1.06 quarts. Write a direct variation equation that relates x liters to y quarts.
Answer:
y= 1.06x
Step-by-step explanation:
We can write an expression for a direct variation equation as
y=kx
K= constant of proportionality
Then, to write direct variation equation that relates x liters to y quarts, we know that k= 1.06 quarts. which is constant, if we substitute we have
y= 1.06x

Answer:
A
Step-by-step explanation:
Assuming you require the distance between the 2 points.
To calculate the distance d use the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 3, - 8) and (x₂, y₂ ) = (- 2, - 3)
d = [tex]\sqrt{(-2+3)^2+(-3+8)^2}[/tex]
= [tex]\sqrt{1^2+5^2}[/tex]
= [tex]\sqrt{1+25}[/tex]
= [tex]\sqrt{26}[/tex] → A

A jar contains four orange marbles numbered one to four. The jar also contains four green marbles numbered one
to four. You randomly pick a marble. It is orange or has a number less than three.
Determine if the scenario involves mutually exclusive events. Then find the probability.
Answer:
1/4
Step-by-step explanation:
Probability of (mutually exclusive events) randomly pick a orange or number less than three is P(A or B) = ( 3/ 4).
What is mutually exclusive event?
" Two events 'A' and 'B' are said to be mutually exclusive events if and only if they are not happening at the same time. It is written as P(A or B)."
Formula used
Probability = (Number of favourable outcome) / Total outcomes
For Mutually exclusive event
P(A or B) = P(A) + P(B)
P(A∩B) = 0
According to the question,
Let O₁, O₂, O₃, O₄ be the orange balls numbered one to four.
Let G₁, G₂, G₃, G₄ be the green balls numbered one to four.
As per condition,
Randomly pick a ball which is orange or numbered less than three is mutually exclusive event.
Let A represents the event ball to be orange.
Let B represents the event ball to be number less than three.
Number of total outcomes = 8
Favourable outcome for event A =4
Favourable outcome for event B =2
Therefore,
P(A) = 4 / 8
P(B) = 2 /8
Substitute the value in the formula of mutually exclusive event P(A or B) we get,
P(A or B) = ( 4 / 8) + ( 2 / 8)
= ( 6 / 8)
= ( 3 / 4)
Hence, probability of ball to be orange or number less than 3 is
P(A or B) = 3 /4.

From point A to point C, we can see there's a wide range between 0 and -10. It's not possible for the answer to be B or D, since the point lays between -10 and 0, and those points are both beyond -10. Between A and C, the best answer would be C. -8.45, since the point is much closer to 10 that it is to the center, around where -5.8 would be.
