Complete Question:
The growth of baby girl Claire is displayed in the graph below. (4, 22) (14, 30)
Answer:
Point Slope: [tex]y - 22 = 0.8(x - 4)[/tex]
Slope Intercept: [tex]y = 0.8x +18.8[/tex]
y intercept: [tex]b = 18.8[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (4,22)[/tex]
[tex](x_2,y_2) = (14,30)[/tex]
Solving (a) Point slope
Using point slope form, an equation is of the form
[tex](y_2 - y_1) = m(x_2 - x_1)[/tex]
First, we need to solve for slope (m):
Make m the subject
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x and y
[tex]m = \frac{30 - 22}{14 - 4}[/tex]
[tex]m = \frac{8}{10}[/tex]
[tex]m = 0.8[/tex]
Next, we form a linear relationship
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = 0.8[/tex] and [tex](x_1,y_1) = (4,22)[/tex]
[tex]y - 22 = 0.8(x - 4)[/tex]
Solving (b): Slope Intercept
[tex]y - 22 = 0.8(x - 4)[/tex]
Open Bracket
[tex]y - 22 = 0.8x - 3.2[/tex]
Add 22 to both sides
[tex]y - 22 +22= 0.8x - 3.2 + 22[/tex]
[tex]y = 0.8x +18.8[/tex]
Solving (c): The y intercept
The general form of an equation is:
[tex]y = mx + b[/tex]
Where b represents the y intercept
By comparison with [tex]y = 0.8x +18.8[/tex]
[tex]b = 18.8[/tex]

Answer:
A. 90 + 13 + x = 180
Step-by-step explanation:
PMW is a straight line and it is made up of the 3 angles, TMW (13), RMT (90), and PMR (x), thus 90 + 13 + x = 180. To find x, you can just take 180 and minus the remaining angles (90 + 13) off it.
Find the slope of the line that passes through the points (5.2) and (3,7).
PLEASE HELP. ILL CASH-APP SOMEONE $35 if they answer this!!
Slope: -2.5
Work: I gather the two points on the line (Which was 5,2 and 3,7) and I used the slope equation. (Slope Equation is y2 - y1 / x2 - x1) After that, I got -5/2, and I divided it, and I got -2.5
PS: I don't need the $35, I'm just glad I can help you.

a trader earns a profit of $6,000 in 1988 and a profit of $8,000 more than double that amounts in 2003. write and expression that represents this situation and find the profit for 2003
Answer:
p = 8000 + 2(6000)
20000
Step-by-step explanation:
Given that:
Profit in 1988 = 6000
Profit in 2003 = 8000 more Than double the profit made in 1998
Hence profit in 2003 (p) can be expressed as :
p = 8000 + 2(6000)
Hence profit in 2003
p = 8000 + 12000
p = 20,000
Busby County is rectangular. A map of the county on a coordinate plane shows the vertices of the county at (5, 8), (8, 8),(8,10),and (5,10). What if the coordinates were A(−2, 5), B(5, 5),C(5,−9),and D(−2,−9)? What would the perimeter of the county be?
Answer:
The answer is below
Step-by-step explanation:
Distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The perimeter of rectangle = 2(length + breadth)
If the vertices are at (5, 8), (8, 8),(8,10),and (5,10), then:
[tex]length=\sqrt{(8-5)^2+(8-8)^2} =3\\\\breadth=\sqrt{(8-8)^2+(10-8)^2} =2[/tex]
The perimeter of the county would be = 2(length + breadth) = 2(3 + 2) = 10 unit
If the vertices are at A(−2, 5), B(5, 5),C(5,−9),and D(−2,−9), then:
[tex]breadth=|AB|=\sqrt{(5-(-2))^2+(5-5)^2} =7\\\\lenght=|BC|=\sqrt{(5-5)^2+(-9-5)^2} =14[/tex]
The perimeter of the county would be = 2(length + breadth) = 2(7 + 14) = 42 unit

it costs $4 to enter the fair. each ride costs $2.50. you have $21.50. how many rides can you go on?
(P.S. can you right the equation/ inequality, please)
Hello!
Equation: y = 2.50x + 47 rides.We can write an expression to show this scenario. Write this in the equation format y = mx + b:
m = rate of change, or cost per ride
b = initial cost, or cost to enter the fair
y = 2.50x + 4
Solve for the amount of rides possible with $21.50:
21.50 = 2.50x + 4
Subtract 4 from both sides to isolate x:
17.50 = 2.50x
Divide both sides by 2.50:
17.50/2.50 = 7 rides.

1. As the value of x increases, the value of f(x) (increases or decreases)?
2.The x-intercept is the point?
Answer:
the first one is just asking if x increases, does the line go up to down if you look from the graph? The y, or f(X) values will increase as X increases. X intercept means when does the line touched the X axis? From the graph the line touches it at (-3,0)

Janka si vložila 3200 eur na termínovaný účet s 1,2 úrokovou mierov koľko bude mať po 1 roku
Answer:
the present value is 3,162 euros
Step-by-step explanation:
The computation of the present value is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
3,200 euros = Present value × (1 + 0.012)^1
3,200 euros = Present value × 1.012^1
Present value is
= 3,200 euros ÷ 1.012
= 3,162 euros
Hence, the present value is 3,162 euros

A television channel shows 3 minutes of adverts in each half hour. How many minutes of adverts does it show from 8am to 11pm
Answer:
90 minutes
Step-by-step explanation:
Given that:
Duration of advert shown per half hour = 3 minutes
3 minutes per 30 minutes = 3 / 30
Number of minutes from 8am to 11pm = 15 hours = (15 * 60) = 900 minutes
3minutes per 30 minutes = x per 900 minutes
3/30 = x / 900
Croas multiply :
30x = 900 * 3
30x = 2700
x = 2700/30
x = 90
Hence, 90 minutes of advert between 8am to 11pm

See screenshot for graph and points - This is not a function because it fails the vertical line test.
Step-by-step explanation:
The vertical line test means that if you can draw a vertical line anywhere on the graph and it hits more than one part of the graph, then it isn't a function.
