The duration of shoot would be 2 hours and Either stylist would cost $282 if the shoot lasted 2 hours.
A fashion photographer needs to hire a stylist to prepare his models.
Let the number of hours stylist take = x
Jayla charges $156 for showing up, plus $63 per hour. So, this can be mathematically written as ,
156 + 63x equation 1
Sally charges $158 plus $62 per hour. So, this can be mathematically written as ,
158 + 62x equation 2
As per the question, the expected duration of his photo shoot, either stylist would cost him the same amount. So we can equate equation 1 and equation 2. On equating equation 1 and equation 2 , we will get
156 + 63x = 158 + 62x
⇒ x = 2
So, the duration would be 2 hours.
Jayla cost = Sally cost = 156 + 63x = 156 + (63 × 2) = 282
Either stylist would cost $282 if the shoot lasted 2 hours.

Find real x and y such that:
(x+yi)^2=x-yi
NEED HELP NOW PLEASE
Answer:
y = sqrt(-2 x - 1/4) + 1/2 (2 i x + i) or y = 1/2 (2 i x + i) - sqrt((-2 x - 1/4))
x = sqrt((-2 i) y + 1/4) + 1/2 (-2 i y + 1) or x = 1/2 (-2 i y + 1) - sqrt(((-2 i) y + 1/4))
Step-by-step explanation:
Solve for y:
(x + (0 + i) y)^2 = x + (0 - i) y
Subtract -i y + x from both sides:
-x + (i y + x)^2 + i y = 0
Expand and collect in terms of y:
-x + x^2 + y (2 i x + i) - y^2 = 0
Multiply both sides by -1:
x - x^2 + y (-2 i x - i) + y^2 = 0
Subtract -x^2 + x from both sides:
y (-2 i x - i) + y^2 = x^2 - x
Add 1/4 (-2 i x - i)^2 to both sides:
1/4 (-2 i x - i)^2 + y (-2 i x - i) + y^2 = 1/4 (-2 i x - i)^2 - x + x^2
Write the left hand side as a square:
(1/2 (-2 i x - i) + y)^2 = 1/4 (-2 i x - i)^2 - x + x^2
Take the square root of both sides:
1/2 (-2 i x - i) + y = sqrt(1/4 (-2 i x - i)^2 - x + x^2) or 1/2 (-2 i x - i) + y = -sqrt(1/4 (-2 i x - i)^2 - x + x^2)
Subtract 1/2 (-2 i x - i) from both sides:
y = 1/2 (2 i x + i) + sqrt((((-2 i) x - i)^2)/4 - x + x^2) or 1/2 (-2 i x - i) + y = -sqrt(1/4 (-2 i x - i)^2 - x + x^2)
1/4 (-2 i x - i)^2 - x + x^2 = -2 x - 1/4:
y = 1/2 (2 i x + i) + sqrt((-2 x - 1/4)) or 1/2 (-2 i x - i) + y = -sqrt(1/4 (-2 i x - i)^2 - x + x^2)
Subtract 1/2 (-2 i x - i) from both sides:
y = sqrt(-2 x - 1/4) + 1/2 (2 i x + i) or y = 1/2 (2 i x + i) - sqrt((((-2 i) x - i)^2)/4 - x + x^2)
1/4 (-2 i x - i)^2 - x + x^2 = -2 x - 1/4:
Answer: y = sqrt(-2 x - 1/4) + 1/2 (2 i x + i) or y = 1/2 (2 i x + i) - sqrt((-2 x - 1/4))
________________________
Solve for x:
(x + (0 + i) y)^2 = x + (0 - i) y
Subtract -i y + x from both sides:
-x + (i y + x)^2 + i y = 0
Expand and collect in terms of x:
x^2 + x (2 i y - 1) + i y - y^2 = 0
Subtract -y^2 + i y from both sides:
x^2 + x (2 i y - 1) = y^2 - i y
Add 1/4 (2 i y - 1)^2 to both sides:
x^2 + x (2 i y - 1) + 1/4 (2 i y - 1)^2 = 1/4 (2 i y - 1)^2 - i y + y^2
Write the left hand side as a square:
(x + 1/2 (2 i y - 1))^2 = 1/4 (2 i y - 1)^2 - i y + y^2
Take the square root of both sides:
x + 1/2 (2 i y - 1) = sqrt(1/4 (2 i y - 1)^2 - i y + y^2) or x + 1/2 (2 i y - 1) = -sqrt(1/4 (2 i y - 1)^2 - i y + y^2)
Subtract 1/2 (2 i y - 1) from both sides:
x = 1/2 (-2 i y + 1) + sqrt((((2 i) y - 1)^2)/4 - i y + y^2) or x + 1/2 (2 i y - 1) = -sqrt(1/4 (2 i y - 1)^2 - i y + y^2)
1/4 (2 i y - 1)^2 - i y + y^2 = -2 i y + 1/4:
x = 1/2 (-2 i y + 1) + sqrt(((-2 i) y + 1/4)) or x + 1/2 (2 i y - 1) = -sqrt(1/4 (2 i y - 1)^2 - i y + y^2)
Subtract 1/2 (2 i y - 1) from both sides:
x = sqrt((-2 i) y + 1/4) + 1/2 (-2 i y + 1) or x = 1/2 (-2 i y + 1) - sqrt(((2 i y - 1)^2)/4 - i y + y^2)
1/4 (2 i y - 1)^2 - i y + y^2 = -2 i y + 1/4:
Answer: x = sqrt((-2 i) y + 1/4) + 1/2 (-2 i y + 1) or x = 1/2 (-2 i y + 1) - sqrt(((-2 i) y + 1/4))

Brian 1days
Bill 3days
Jacob 2days
Pete 2days
Sasha 3days
∴ Total number of days will = 4 + 5 + 1 + 3 + 2 + 2 + 3 = 20 days
∴ Total employee count is 7.
∴ Mean Will be [tex] \frac{20}{7} [/tex]

The school mary goes to is selling tickets to a fall musical. On the first day of ticket sales the school sold 7 senior citizen tickets and 6 students tickets of $69. The school took in $53 on the second day by selling 7 senior citizen tickets and 4 student tickets. find the price of one senior citizen ticket an the price of one child ticket
The price of one senior citizen ticket is $8 and that of a child ticket is $3.
Let the price of one senior citizen ticket be x
and the price of one student ticket be y
Thus, for the first day, we can make the following equation-
7x + 6y = 69
and similarly, we can make an equation for the second day as-
7x + 4y = 53
Now, we can solve these two linear equations to find the value of x and y.
Subtracting equation 2 from 1 we get-
(7x + 6y) - (7x + 4y) = 69 - 53
7x - 7x + 6y - 4y = 16
6y - 4y = 16
2y = 16
y = 16/2
y = 8
Substituting the value of y in any of the two equations we can find the value of x-
7x + 6(8) = 69
7x = 69 - 48
x = 21/7
x = 3
Thus, the price of one senior citizen ticket is $8 and that of a child ticket is $3.

he profit earned by a hot dog stand is a linear function of the number of hot dogs sold. It costs the owner $48 dollars each morning for the day’s supply of hot dogs, buns and mustard, but he earns $2 profit for each hot dog sold. Which equation represents y, the profit earned by the hot dog stand for x hot dogs sold?
y=48x−2
y=48x+2
y=2x−48
y=2x+48
The linear function that represents the profit earned is: C. y = 2x − 48.
How to Write a Linear Function?The linear Function can be written as y = mx + b, which is in slope-intercept form, where we have:
x and y as the variables.m as the slope/unit rate.b as the starting value or y-intercept of the linear function.From the information given, we have:
x = number of hot dogs sold
y = Profit earned
m = unit rate = 2
b = starting value = -48 (this is negative because the profit on each hot dog sold must be deducted from the cost for each morning.)
Therefore, substitute m = 2 and b = -48 into y = mx + b to write the linear function:

The scale of a map is 1: 250000 the actual distance between two cities is 80km calculate the distance on the map give your answer in centimeters
PLS SOMEONE ANSWER❗️
The scale of a map exists 1: 250000 the actual distance between two cities exists 80km then the two cities exists 72 cm apart on the map.
How to estimate the actual distance?Given that the representative fraction exists 1/250000.
We know that the representative fraction exists the ratio of map distance to the corresponding ground distance exists independent of units of measurement.
This implies that 1 cm on the map exists actually 250000 cm distance.
We will convert this 250000 cm into m as 1 m = 100 cm.
[tex]\[250000 \times \dfrac{1}{{100}}[/tex] m = 2500 m
To convert this into km as 1 km = 1000 m.
[tex]\[2500 \times \dfrac{1}{{1000}}[/tex] km = 2.5 km
So, 1 cm on the map exists 2.5 km actual distance.
To find the distance on the map corresponding to 180 km on ground.
[tex]\dfrac{{180}}{{2.5}}[/tex] cm = [tex]$\frac{{1800}}{{25}}[/tex] cm = 72 cm
Therefore, the two cities exists 72 cm apart on the map.
We exists supposed to scale the representative fraction properly to avoid any miscalculation. Also, we will take care of the scales properly i.e. kilometers, meters and centimeters.
The complete question is:
The scale of a map is 1: 250 000.

When a transversal crosses parallel lines corresponding angles are congruent.
What are corresponding angles?
Two lines are parallel if and only if the two angles of any pair of transversal corresponding angles are congruent (equal in measure). Proposition 1.28 of Euclid's Elements, an absolute geometry theorem (therefore true in both hyperbolic and Euclidean Geometry), demonstrates that if the angles of two transversals are corresponding, the two lines are parallel (non-intersecting). According to Euclid's parallel postulate, if two lines are parallel, the angles of a pair of corresponding angles are congruent (Proposition 1.29 of Euclid's Elements). If the angles of one pair of related angles are congruent, the angles of the remaining pairs are likewise congruent.
