Oceanside bike rental shop charges seventeen dollars plus seven dollars an hour for renting a bike. Jason paid eighty dollars to rent a bike. How many hours did he have to pay to have the bike checked out?
Answer:This is a linear equation.
y = mx+b
y is the total cost.
The slope m is the rate: that's 9 dollars per hour.
x is the number of hours.
b is the initial value: that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hour
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
80-17=63
63/7 = 9
7 times 9 = 63

Function f approximately represents the trajectory of an airplane in an air show, where x is the horizontal distance of the flight, in kilometers. What is the symmetry of the function?
Answer:
[tex](\frac{3}{2},102)[/tex]
Step-by-step explanation:
Given
[tex]f(x)=88x^2-264x+300[/tex] --- Missing from the question
Required
The symmetry
First, we express f(x) as: [tex]f(x) = a(x - h)^2 + k[/tex]
Where the symmetry is: (h, y) and x = h
Equate f(x) to 0
[tex]88x^2-264x+300 = 0[/tex]
Subtract 300 from both sides
[tex]88x^2-264x+300 - 300= 0 - 300[/tex]
[tex]88x^2 - 264x= - 300[/tex]
Factorize
[tex]88(x^2 - 3x) = -300[/tex]
On the left-hand side, the coefficient of x is -3.
Divide by 2 and add the square to both sides.
So, we have:
[tex]88(x^2 - 3x) + (\frac{3}{2})^2 = -300 + (\frac{3}{2})^2[/tex]
Multiply the new terms by 88 (to make it factorizable)
[tex]88(x^2 - 3x ) +88* (\frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
Factorize
[tex]88(x^2 - 3x + (\frac{3}{2})^2) = -300 + 88 * (\frac{3}{2})^2[/tex]
The quadratic expression in the bracket is a perfect square. This gives:
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * \frac{9}{4}[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 22 * 9[/tex]
[tex]88(x - \frac{3}{2})^2 = -102[/tex]
Add 102 to both sides
[tex]88(x - \frac{3}{2})^2 +102= -102 + 102[/tex]
[tex]88(x - \frac{3}{2})^2 +102= 0[/tex]
Equate to y
[tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
Recall that:
The symmetry is: (h, y)
By comparison with [tex]f(x) = a(x - h)^2 + k[/tex] and x = h
[tex]h = \frac{3}{2}[/tex]
So: [tex]x = \frac{3}{2}[/tex]
Substitute [tex]x = \frac{3}{2}[/tex] in [tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(\frac{3}{2} - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(0)^2 +102[/tex]
[tex]y = 0 +102[/tex]
[tex]y = 102[/tex]
So, the symmetry is: [tex](\frac{3}{2},102)[/tex]

1) Which of the following is true about circles
2 radius's for a circle is equal to it's diameter
1 diameter of a circle is equal to it's circumference
pi is a ratio of the distance around a circle to the distance across a circle
Circumference is distance across a circle
Circumference for a circle is found by multiplying pi by diameter
Circumference and Area of a circle are the same thing

The figure shows four smaller squares in the corners of a large square. the smaller squares have sides of length 1cm, 2cm, 3cm and 4cm in anticlockwise order and the sides of the large square have length of 11cm.
What is the area of the shaded quadrilateral? (see attachment)
Answer:
B. 36 [tex]cm^{2}[/tex]
Step-by-step explanation:
The shaded quadrilateral has a shape of a trapezium.
Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the side length parallel to the base, b is the base and h is the height.
The height of the figure = 11 - (4 + 1)
= 11 - 5
= 6
The height of the figure is 6 cm.
The length of its base = 11 - (1 + 2)
= 11 - 3
= 8
The length of its base is 8 cm.
The length of the side parallel to base = 11 - (4 + 3)
= 11 - 7
= 4
The parallel side length to base is 4 cm.
Area of quadrilateral = [tex]\frac{1}{2}[/tex](a + b)h
= [tex]\frac{1}{2}[/tex](4 + 8)6
= 12 x 3
= 36
Area of quadrilateral = 36 [tex]cm^{2}[/tex]

Answer for 2y + 4/x = 10
Answer:
Y = 5 - 2/x
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
You want to isolate x so first, you have to multiply the whole equation by 1/4 so it will look like 1/4(2y+4/x=10). Simplify this to get 1/2y+x=5/2. You want to isolate x, so you have to subtract 1/2 from each side, this will make the equation x=5/2-1/2. Simplify this to get x=4/2 which can also be simplified to x=2. Therefore, the answer is x=2

Can someone please help me with math
Answer:
B
Step-by-step explanation:
they want us to find the equation in slope intercept form
which is y= mx + b
where m = slope and b = y intercept
the slope is change in y over change in x
as y goes up 1 x goes up 1 so the slope is 1 or m=1
the y intercept is at point (0,1)
so the y intercept is 1
now we add it all together and get that the equation Is
y=x+1

what is the equation of the line?
Answer:
x=3
Step-by-step explanation:
the x axis is going across by 2 and the number in between 2 and 4 is 3 and the line is going through the x axis hence the equation of the line is x=3
Answer:
[tex]x=3[/tex]
Step-by-step explanation:
Normally, linear equations would be written in slope-intercept form, [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis). However, linear equations for horizontal or vertical lines are organized differently.
Here, we're given a vertical line. Vertical lines are written like [tex]x=d[/tex], where [tex]d[/tex] is the x-intercept, or the value of x when the line crosses the x-axis.
From the graph, we can tell that the x-intercept is 3. Therefore, our equation would be [tex]x=3[/tex].
I hope this helps!
What is the measure of angle LMN ?
Answer:
g = 9°
hence LMN = 135 + 18 = 153°
Step-by-step explanation:
straight line is 180°
180 - 18 = 162
162 = 18g
g = 9
Answer:
Step-by-step explanation:
So try to find the total angle so
15g+18+3g=180
18g=180-18
18g=162
g=9
angle LMN=15x9+18
=135+18
LMN=153 degrees
angle PMN=3x9
= 27 degrees

Step-by-step explanation:
becasue the slope is very harddddd
please and thank you
The answer is D. Y = 63 + 2 = 65
The given equation is y = x + 2, the height is given as 63. The height is the x value so you would replace x in the equation with 63 and solve for y.
