3x=300
x=300÷3
x=100
A photographer charges $25 to travel to a client's location, plus $55 per hour for her
services. What is the duration, in hours, of a photography session that costs $465?
Answer:
8 Hours
Step-by-step explanation:
First, you have to subtract the 25$ because we already know that that is a stable value (meaning it will not change)
Then, you have to divide 440 by 55 to get an answer of 8 hours for the session :D
To find total multiply 55 by number of hours (h) and then add 25:
Total = 55h + 25
Given the total solve for h:
465 = 55h + 25
Subtract 25 from both sides
440 = 55h
Divide both sides by 55
H = 440/55
H = 8
It was 8 hours

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Brian is n years old.
Then the age of Brian after 47 years will be given as,
⇒ n + 47
The age of Brian after 47 years will be n + 47.

Answer:
D) 18 units
Step-by-step explanation:
The ratio is
2 : 3
The actual number values are
12 : ?
Divide 12 by 2 (square A's side) = 6
Multiply 6 by 3 (square B's side) = 18
What is the solution to the equation ? (x - 2) ^ (1/2) + 4 = x
Answer:
x is equal to both 3 and 6.
Step-by-step explanation:
[tex]\sqrt{x - 2} + 4 = x\\\sqrt{x - 2} = x - 4\\x - 2 = (x - 4)^2\\x - 2 = x^2 - 8x + 16\\x^2 - 9x + 18 = 0\\(x - 3)(x - 6) = 0\\[/tex]
So x values of 3 and 6 will make this statement true.
OA.
The slope is negative.
OB.
The slope is positive.
Oc.
The slope is zero.
D.
The slope is undefined.
The true statement about the slope is the slope is positive.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
To find the slope take two points from the graph as (0, 4) and (5, 6)
So, Slope of line
= (6-4) / (5-0)
= 2 /5
= 0.4
Thus, the slope of line is positive.

1. Determine f -1 (x) for each of the given functions
f (x) =2x-3
2. Determine f -1 (x) for each of the given functions
f (x) = x over x+2
Step-by-step explanation:
1) f(x) =2x -3
y=2x - 3
x= 2y -3
2y =x + 3
y = x+3 over 2
f(x)^-1 = x+3 over 2
2) f(x) = x /x+2
y= x / x+2
y / y+2 = x
y = (y+2)x
y= xy +2x
y -xy = 2x
y( -x +1) = 2x
y= 2x over -x + 1
f(x)^1 = 2x over -x + 1
