According to the question ,
The base price is $25 per week . And per hour charge is $3/hour .So as per the question if we assume that the babysitter looked after the child for x hours in a week then , the total charge will be ,
→ Charge = $3/hr * x hr= $3x
So the total cost for a week , will be ,
→ Total cost = Base price + Charge
→ Total cost = $25 + $3x
And in the question we are told to assume total cost to be $C . Therefore ,
→ $C = $ (25 +3x)
→ C = 25 + 3x
Hence the required equation is C = 25 + 3x.

Lin’s family is out for a bike ride when her dad stops to take a picture of the scenery. He tells the rest of the family to keep going and that he’ll catch up. Lin's dad spends 5 minutes taking the photo and then rides at 0.24 miles per minute until he meets up with the rest of the family further along the bike path. Lin and the rest were riding at 0.18 miles per minute.
It took Lin's dad about 3.6 miles for him to meet up with his family.
SpeedSpeed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let d represent the distance travelled by Lin to meet up with his family. Hence:
Total time for Lin's Dad = d/0.24 + 5
Total time for Lin = d/0.18
Hence:
d/0.24 + 5 = d/0.18
100d/24 + 5 = 100d/18
1800d + 2160 = 2400d

We are given:
abcissa(x-coordinate) of given point: -6
let's say the ordinate(y-coordinate) of the given point is y
distance of the given point from (1,3) = √74
we can rewrite the given information as:
the distance between the points (-6,y) and (1,3) is √74
finding y:
we know that in order to find the distance between any two points, we use the distance formula, which goes as follows:
distance = [tex]\sqrt{(x_1-x_2)^2 + (y_1 - y_2)^2}[/tex]
from the data we are given, let's say that:
(x₁, y₁) = (-6, y)
(x₂, y₂) = (1, 3)
(you can use them interchangably, there is no restriction on which point gets to be labelled as 1)
plugging this in the distance formula, we get:
distance = [tex]\sqrt{(-6-1)^2 + (y - 3)^2}[/tex]
we are also given that the distance is √74,
√74 = [tex]\sqrt{(-7)^2 + (y - 3)^2}[/tex]
squaring both sides to get rid of the square root
74 = (-7)² + (y - 3)²
74 = 49 + y² + (3)² -2(y)(3) (using the "square of sum" identity)
74 = 49 + y² + 9 - 6y
74 = 58 + y² - 6y
y² - 6y + 58 - 74 = 0 (subtracting 74 from both sides)
y² - 6y - 16 = 0
y² - 8y + 2y - 16 = 0 (splitting the middle term)
y(y - 8) + 2(y - 8) = 0
(y + 2)(y - 8) = 0
which means that:
y + 2 = 0 , y - 8 = 0
y = -2 , y = 8
These are the two possible values of y
8.
We are given:
points A and B
A: (3, y)
B: (6, 2)
distance between A and B = 5 units
finding possible values of y
here, we will use the distance formula again to find the value of y
distance formula: [tex]\sqrt{(x_a-x_b)^2 + (y_a - y_b)^2}[/tex]
plugging the given values, we get:
5 = [tex]\sqrt{(3-6)^2 + (y - 2)^2}[/tex]
25 = (3 - 6)² + (y - 2)² (squaring both sides)
25 = (-3)² + (y - 2)²
25 = 9 + y² + (2)² - 2(y)(2)
25 = 9 + y² + 4 - 4y
y² - 4y + 9 + 4 - 25 = 0 (subtracting 25 from both sides)
y² - 4y - 12 = 0
y² - 6y + 2y - 12 = 0 (splitting the middle term)
y(y - 6) + 2(y - 6) = 0
(y + 2)(y - 6) = 0
y + 2 = 0 , y - 6 = 0
y = - 2 , y = 6
These are the two possible values of y
Solve the simultaneous equations
x+3y=11. X+2y=9
Answer:
y=2, x=5
Step-by-step explanation:
we can subtract the system of equations to eliminate x and to find the value of 1 y
x+3y=11
minus
x+2y+9
=y=2, now we can replace the value y (2) into either equation to find the value of x
x+3(2)=11
x+6=11
x=5
HELP i don’t know what the slope is or how to do this!!!
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]
please like
Answer:
undefined
Step-by-step explanation:
Slope is a measure of the vertical change relative to the horizontal change. On an x-y graph, it will be the difference in y-coordinates divided by the corresponding difference in x-coordinates. It is often referred to using the letter m.
m = (y2 -y1)/(x2 -x1) . . . . . slope of line between points (x1, y1) and (x2, y2)
It does not matter which points you call point 1 and point 2.
__
For the points given on the graph we can compute the slope to be ...
m = (2 -(-3))/(-1 -(-1)) = 5/0
The zero in the denominator makes this value "undefined." So, we say the slope of any vertical line is "undefined."

amt of water drained =28% of 1550 =434l
now,
water left the tank =1550l-434l =1116l
The supply and demand curves for a market are graft below with price in dollars and quantity in thousands. Which of the following would result from an increase in the supply curve? a. a market equilibrium price greater than $30 b. A market equilibrium price less than $30 c. A market equilibrium quantity less than $30 d. A market equilibrium quantity greater than $30
Answer:
B) A market equilibrium price less than $30
Step-by-step explanation:
When the supply curve increases, it shifts to the right, making the market equilibrium price lower because the oversupply of the quantity causes demand to drive down.

Graph the parabola.
y=3x²-4
Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function
button.
Answer:
Vertex: (0, -4)
Graph: I can't share a link so you can go to desmos and paste your equation
Step-by-step explanation:
the vertex is where the axis of symmetry meets with the parabola.
The axis of symmetry is (-b)/(2a) which equals 0 because there is no linear x value
therefore,
y=3(0)^2-4
=-4
so the vertex is (0, -4)
to find the other points, list two x values larger than 0 and substitute into the equation to find y
list two x values smaller than 0 and substitute to find the points on the left of the vertex.

Find the surface area of the cylinder. Use 3.14 for pi. Do not round the answer
690.28
650.83
500.83

Answer:
C) 500.83
Step-by-step explanation:
Surface area for a cylinder formula:
SA = 2πrh + 2πr²
Given:
d = 11
r = d/2 = 11/2 = 5.5
h = 9
Work:
SA = 2πrh + 2πr²
SA = 2(3.14)(5.5)(9) + 2(3.14)(5.5)²
SA = 310.86 + 2(3.14)(30.25)
SA = 310.86 + 189.97
SA = 500.83
Frank is on the swim team. Each week he swims a total of 6,000 meters. How many kilometers does he swim each week?
Be sure to include the correct unit in your answer
Answer:
6 km
Step-by-step explanation:
1 meter = 1/1000 km
(1 meter = 1/1000 km) x 1000
1000 meters = 1 km
6000 meters = ?
1 x 6000m = 1000 x ?
6000 = 1000 x 6
6000/1000 = 1000 x 6/1000
6 = 6
Both sides divided by 1000 are 6, so the answer is 6 km.

3(3x [tex] {}^{2} [/tex]+ 1)=12x
2)Find the quadratic equation
[tex]9y {}^{2} - 12y - 14 = 0[/tex]
Step-by-step explanation:
"find" ?
the equations are already there.
do you mean solve in the sense of finding the zero points of the equations ?
if so,
the general solution of a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
3(3x² + 1) = 12x
9x² + 3 = 12 x
9x² - 12x + 3 = 0
a = 9
b = -12
c = 3
x = (12 ± sqrt(144 - 4×9×3))/18 = (12 ± sqrt(144-108))/18 =
= (12 ± sqrt(36))/18 = (12 ± 6)/18
x1 = (12 + 6) / 18 = 18/18 = 1
x2 = (12 - 6) / 18 = 6/18 = 1/3 = 0.3333333...
9y² - 12y - 14 = 0
same thing, we just use y instead of x.
a = 9
b = -12
c = -14
y = (12 ± sqrt(144 - 4×9×-14))/18 = (12 ± sqrt(144+504)/18 =
= (12 ± sqrt(648))/18 = (12 ± sqrt(324×2))/18 =
= (12 ± 18×sqrt(2))/18
y1 = (12 + 18×sqrt(2))/18 = 12/18 + sqrt(2) = 2/3 + sqrt(2) =
= 0.942809042...
y2 = (12 - 18×sqrt(2))/18 = 12/18 - sqrt(2) = 2/3 - sqrt(2) =
= -0.747546896...
