Answer:
y = 1x + 1/2
Step-by-step explanation:
y2 - y1 / x2 - x1
2 - 3/2 / 3/2 - 1
= 1/2 / 1/2
= 1
y = 1x + b
3/2 = 1(1) + b
3/2 = 1 + b
1/2 = b
Just this one and show your work if you can please ^^
Answer:
m = 1
Step-by-step explanation:
We can start by moving all the terms with m to one side by subtracting m from both sides(to cancel out):
11m + 13 = m + 23
-m -m
10m + 13 = 23
Now, to single out the m term, we can subtract 13 from both sides:
10m + 13 = 23
- 13 -13
10m = 10
To find the value of m, we can divide both sides by 10:
10m = 10
÷ 10 ÷10
m = 1

What is the equation, in slope-intercept form, that relates the cost compared to the miles traveled for a Red Cab?
Step-by-step explanation:
the general slope intercept form is
y = ax + b
a is the slope. it is expressed as ratio y change / x change when going from one point to another.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b.
costs are on the y axis, miles are in the x axis.
so, what points do we see on the chart for the red taxi ?
let's start with the point right in the y-axis : (0, 2).
that gives us the y- intercept automatically.
and then let's pick e.g. the point, where both lines cross : (3, 8).
so, for the slope we look at the coordinate changes :
x changes by +3 (from 0 to 3).
y changes by +6 (from 2 to 8).
the slope is then 6/3 = 2.
and again, the y- intercept is +2.
therefore, the line equation is
y = 2x + 2

I need to find how many boxes can be shipped in an 18 hour period. I also provided the graph to help answer
Answer:
216 boxes
Step-by-step explanation:
you can see by the highlighted point that in 5 hours 60 boxes are shipped. that means 12 boxes per hour (60/5=12)
When you know this just multiply the hours by 12 and you get 12*18=216
10. A donut shop serves plain and chocolate
donuts at a ratio of 5 to 3. Based on this
ratio, how many chocolate donuts will be
served if there are a total of 120 donuts
served?
Answer:
75
Step-by-step explanation
5+3=8
120/8=15
15(5)=75
If there are a total of 120 donuts served 45 will be chocolate donuts.
What is a ratio?A ratio is a comparison between two similar quantities in simplest form.
A ratio a : b can be written as a/b.
Given, A donut shop serves plain and chocolate donuts at a ratio of 5 to 3.
∴ Plain donuts : Chocolate donuts = 3 : 5.
If there are a total of 120 donuts served chocolate donuts will be,
= 3/(5 + 3)×120.
= (3/8)×120.
= 45 chocolate donuts.

Given g(x)=5x+4, solve for x when g (x)=9
Answer:
g( 1 ) = 9
Step-by-step explanation:
Remember that in linear functions expressed in the function notation, g(x), this means that for any allowed value of x, we can use the equation to find the corresponding value of g(x) or y (output). Thus, the linear function g(x) = 5x + 4 is essentially the same as expressing the given equation as: y = 5x + 4.
Solution:Given the linear function, g(x) = 5x + 4, we can solve for x when g(x) = 9 by substituting the value of the output, g(x) = 9, into the function.
g(x) = 5x + 4
9 = 5x + 4
Subtract 4 from both sides:
9 - 4 = 5x + 4 - 4
5 = 5x
Divide both sides by 5 to solve for x:
[tex]\large\mathsf{\frac{5}{5}\:=\:\frac{5x}{5}}[/tex]
x = 1
Therefore, when g(x) = 9, the value of x = 1. Another way of expressing this is: g( 1 ) = 9.

The sum of two integers is 75. One of the numbers is three more than the other. What is the larger integer?
Step-by-step explanation:
Assign variables to the integers
Let the larger integer be 'A' and the smaller 'b'
Write Equations based on the Question
Since the sum of the integers is 75, then A + b = 75 (eq
1)
Since the larger number is three times more than the smaller, then A = 3b (eq2)
Combine the Equations and solve for variables
By substituting the value of A in eq1 into eq2
⇒ 3b + b = 75
4b = 75
b = ⁷⁵/₄ = 18.25
By substituting the value of b into eq1
⇒ A = 3(⁷⁵/₄)
A = ²²⁵/₄ = 56.25
∴ the larger integer is 56.25Check our Answer:
A + b = 56.25 + 18.75 = 75
39 is the answer
If $x$ is the larger integer, then the smaller integer is $x-3$. We find the sum and set it equal to 75:$$x+x-3=75\qquad\Rightarrow \qquad 2x=78\qquad\Rightarrow \qquad x=39$$The larger integer is $\boxed{39}$.

A man has 14 coins in his pocket, all of which are dimes and quarters. If the total value of his change is $2.30, how many dimes and how many
quarters does he have?
Answer:
8 dimes and 6 quarters
===================================================
Work Shown:
d = number of dimes
q = number of quarters
d+q = 14 since this is his coin total; equation solves to d = 14-q
10d+25q = 230 which is the total value in cents
10(14-q)+25q = 230 .... apply substitution rule
140-10q+25q = 230
15q+140 = 230
15q = 230-140
15q = 90
q = 90/15
q = 6 = number of quarters
d = 14-q
d = 14-6
d = 8 = number of dimes
-----------------
Check:
8 dimes + 6 quarters = 14 coins
8 dimes = 8*10 = 80 cents
6 quarters = 6*25 = 150 cents
8 dimes + 6 quarters = 80 cents + 150 cents = 230 cents = $2.30

Hello, your
Step-by-step explanation:
For this particular problem (with units in mind), the formula for arc length is
Arc length
=
2
π
r
⋅
(
x
360
∘
)
,
Where
x
is the central angle measure and
r
is the radius of the circle.
You don't really have to work too hard to remember this formula. The arc length formula is easy to remember because it is just the circumference of the circle times the central angle over
360
∘
.
Anyway, let's continue with the problem. We are given that the central angle is
60
∘
, and that
r
, our radius, is
9
feet. So, let's plug that into our equation to find the arc length, in feet:
Arc length
=
2
π
r
⋅
(
x
360
∘
)
Arc length
=
2
π
(
9
)
⋅
(
60
∘
360
∘
)
Now, you might be tempted to plug this in your calculator, but let's simplify it a little bit more.
Arc length
=
2
π
(
9
)
⋅
(
60

Arc length
=

(

6
)
Arc length
=
3

feet
So, if you wanted an exact answer, it would be that the arc length is
3
π
feet
. If you wanted an approximate answer, then you can type
3

π
in your calculator to get a value of about
9.425

as you alternative answer.

The function h (d) = 2d + 4.3 relates the height (h) of the water in a fountain in feet to the diameter (d) of the pipe carrying the water in inches. Find h (1.5) and interpret your solution in the context of the problem find the value of d when h (d) = 10.3 and interpret your solution in the context of the problem
Answer:
h(1.5) = 7.3 ft
h(10.3) = 24.9 ft
Step-by-step explanation:
Given the function h(d) = 2d + 4.3,
where:
h = height of the water in a fountain (in feet)
d = diameter of the pipe carrying the water (in inches)
h(1.5)Substitute the input value of d = 1.5, into the function:
h(1.5) = 2(1.5) + 4.3
h(1.5) = 3 + 4.3
h(1.5) = 7 feet
The height of the water in a fountain is 7 feet when the diameter of the pipe is 1.5 inches.
h(10.3)Substitute the input value of d = 10.3, into the function:
h(10.3) = 2(10.3) + 4.3
h(10.3) = 20.6 + 4.3
h(10.3) = 24.9 feet
The height of the water in a fountain is 24.9 feet when the diameter of the pipe is 10.3 inches.
Context of the solutions to h(1.5) and h(10.3):The solutions to both functions show the relationship between the diameter of the pipe to the height of the water in a fountain. The height of the water in fountain increases relative to the diameter of the pipe. In other words, as the diameter or the size of the pipe increases or widens, the height of the water in a fountain also increases.

his strategy is to do it in parts. 10x7 is a little easier since anything x 10 just gets a 0 on the end of it. so 10x7=70 then he subtracted 7 to get the answer to 9x7 which is 63
How to solve 3x+12=2x
Answer: x=-12
Step-by-step explanation:
subtract 12 from both sides
3x=2x-12
subtract 2x from both sides
x=-12
Subtract 12 from both sides of the equation:
3x + 12 = 2x
3x + 12 - 12 = 2x - 12
Simplify:
3x = 2x - 12
Subtract 2x from both sides of the equation:
3x = 2x - 12
3x-2x = 2x - 12-2x
Simplify:
