Answer:
[tex]y = 3[/tex]
Step-by-step explanation:
Given
Trip = 250 miles
Speed for first x hours = 60 miles/hour
Speed for next y hours = 50 miles/hour
x = 1
Required
Find y
To solve this question, we'll make use of:
[tex]Distance = Speed * Time[/tex]
For x hours:
[tex]Distance = 60miles/hour * x[/tex]
Substitute 1 hour for x
[tex]Distance = 60\ miles/hour * 1\hour[/tex]
[tex]Distance = 60\ mile[/tex]
For y hours:
[tex]Distance = 50\ miles/hour * y\ hours[/tex]
[tex]Distance = 50y\ miles[/tex]
Given that total distance is 210 miles;
We have that:
[tex]Total Distance = 60\ miles + 50y\ miles[/tex]
[tex]210\ miles = 60\ miles + 50y\ miles[/tex]
Solve for y
[tex]210 - 60 = 50y[/tex]
[tex]150 = 50y[/tex]
[tex]y = \frac{150}{50}[/tex]
[tex]y = 3[/tex]
Hence,
y = 3 hours

Answer:
[tex]m=158[/tex]
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Hence,
[tex](m-29)+51=180[/tex]
Remove brackets:
[tex]m-29+51=180[/tex]
[tex]m+22=180[/tex]
Subtract 22 from both sides:
[tex]m+22-22=180-22[/tex]
[tex]m=158[/tex]
Answer:
[tex]\displaystyle 158 = m[/tex]
Step-by-step explanation:
Both angles form a linear pair, making them supplementary angles. This means you set both expressions equivalent to one hundred eighty degrees:
[tex]\displaystyle 180° = 51° + [m - 29]° \hookrightarrow 180° = [m + 22]° \\ \\ \boxed{158 = m}[/tex]

The telephone company offers two billing plans for local calls. Plan 1 charges $38 per month for unlimited calls and Plan 2 charges $18 per month plus $0.04 per call.
The question is incomplete:
The telephone company offers two billing plans for local calls. Plan 1 charges $38 per month for unlimited calls and Plan 2 charges $18 per month plus $0.04 per call.
Use an inequality to find the number of monthly calls for which plan 1 is more economical than plan 2.
Answer:
Plan 1 is more economical than plan 2 when you make more than 500 monthly calls.
Step-by-step explanation:
Plan 1 costs $38 per month for unlimited calls and plan 2 costs $18 per month plus $0.04 per call which is: 18+0.04x and you can infer that plan 1 would be cheaper when you have to pay more than $38 using plan 2 and you can express it with the inequality:
18+0.04x>38, where x is the amount of monthly calls
Now, you can solve for x:
0.04x>20
x>20/0.04
x>500
According to this, plan 1 is more economical than plan 2 when you make more than 500 monthly calls.

What is Mathematical equation ?
By definition, an equation is a mathematical statement made up of two expressions linked by an equal sign. In other words the equation represents the graph between x and y that is for each value of x there exist one value of y.
So, When we graph a line using slope and y-intercept, the first point that you graph is y-intercept.
Let, consider the equation of y = mx+c, where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.
Therefore, When we graph a line using slope and y-intercept, the first point that you graph is y-intercept.

Step-by-step explanation:
Suppose that you plan on taking a summer job selling magazine subscriptions. The magazine company will pay you $ 1.25 for selling the first subscription. For each additional subscription sold, the magazine company will pay you 15 cents more than what was paid for the previous subscription. How much will you earn by selling 175 magazine subscriptions?
Answer: $27.35
Step-by-step explanation:
First let's find the variables.We will use x to represent the number of subscription sold and y we will represent the amount of money you will get paid.
So we know that , if you sell One You will get $1.25 so we could represent it by the point (1,1.25) .
Now the second statement says that if you sell an additional subscription you will get an additional 15 cents or $0.15.Which means if you sell the second subscription, you will get $1.40 because it is an additional 15 cents. We can also represent that by the point (2,1.40)
Now using the two points come up with an equation.
(1,1.25)
(2,1.40) Find the slope and y intercept.
TO find the slope find the difference between y and divide it by the difference in x.
1.25 - 1.40 = 0.15
1 - 2 = 1
0.15/ 1 = 0.15 So the slope is 0.15
Now use the point to find the y intercept. using the y-intercept formula,
y = mx + b
1.25 = 0.15(1) + b
1.25 = 0.15 + b
-0.15 0.15
b = 1.1
We can now write the equation y = 0.15x + 1.1 to represent the whole situation where x is still the number of subscriptions sold and y is the money you will get paid. Now to find how much you will earn for 175 subscriptions, you will input 175 for x and solve for y.
y = 0.15(175) + 1.1
y = 26.25 + 1.1
y = 27.35
So you will earn $27.35 for 175 subscriptions
