Graph the system of equations below on a piece of paper. What is the solution?
y = x – 1
y = 3x + 1

A. (2, 1)

B. (1, –2)

C. (–1, –1)

D. (–1, –2)
Answer:
Option D is correct
Solution = (-1, -2)
Step-by-step explanation:
Given the equation:
y = x – 1 ....[1]
y = 3x + 1 ....[2]
Equate equation [1] and [2] to solve for x.
[tex]x-1=3x+1[/tex]
Subtract x from both sides we have;
[tex]-1=2x+1[/tex]
Subtract 1 from both sides we have;
[tex]-2=2x[/tex]
Divide both sides by 2 we have;
x = -1
Substitute the value of x = -1 in [1] we have;
y=-1-1 = -2
Graphically:
Graph the system of equations as shown below.
The intersection point of these lines is the solution for the given system of equation
⇒ (-1, -2)
Therefore, the solution for the given system of equation is, (-1, -2)
What is y-10=9(x+8) written in standard form?
Answer:
-9x+y=82
Step-by-step explanation:
hope this helped!
The equation y-10=9(x+8) can be transformed into standard form by distributing, simplifying, and rearranging terms to get 9x - y = -82.
Explanation:The given equation is y-10=9(x+8), and we're asked to change this slope-intercept form into the standard form. First, we'll start by distributing the 9 to both x and 8 which will result in y-10 = 9x + 72. Then, we'll bring terms involving x and y to one side of the equation, leading to -9x + y = 82. This is almost in standard form, but typically we want the leading coefficient (the coefficient of x) to be positive, so we'll multiply the equation by -1. This gives us 9x - y = -82, which is the equation in standard form.

To transport 228 people to an island island ferry make six different trips on each trip the ferry carries the same number of people how many people does the ferry transport on each trip
Answer:
38 people
Step-by-step explanation:
Given: To transport [tex]228[/tex] people to an island island ferry make six different trips on each trip the ferry carries the same number of people.
To Find: how many people does the ferry transport on each trip.
Solution:
Total number of people to be transported [tex]=228[/tex]
Total number of trips made by island ferry [tex]=6[/tex]
As ferry carries same number of people in each trip
number of people ferry transport in each ferry [tex]=\frac{\text{total number of people to be transported}}{\text{total number of ferries}}[/tex]
putting values,
[tex]=\frac{228}{6}[/tex]
[tex]38[/tex]
Hence number of people ferry transport in each island ferry is [tex]38[/tex].

Which step could be used to solve x + 3.6 = -1.7 for x in one step? Check all that apply.
[ ] add 3.6 to both sides
[ ] add -3.6 to both sides
[ ] add 1.7 to both sides
[ ] add -1.7 to both sides
[ ] subtract 3.6 from both sides
[ ] subtract 1.7 from both sides
Answer: Option (2) and (5) are the correct options.
Step-by-step explanation:
Since, the given expression, x+3.6= -1.7
If we add -3.6 in both sides then we get x+3.6+(-3.6)=1.7-3.6⇒x= -1.9
while,
If we subtract 3.6 from both sides then we get x+3.6-3.6=1.7-3.6⇒x= -1.9
Thus, In the above by adding -3.6 and by subtracting 3.6 we get the value of x in one step.(because after this only x remains in LHS of the given expression)
Therefore, Option (2) and (5) are correct.
Note: Except these two options we can not get x in one step. (we can not get single x in LHS of the given expression by the other options.)

Step-by-step explanation:
In a poll, respondents were asked whether they had ever been in a car accident. 215 respondents indicated that they had been in a car accident and 449 respondents said that they had not been in a car accident. If one of these respondents is randomly selected, what is the probability of getting someone who has been in a car accident? Round to the nearest thousandth, if necessary
The probability of getting someone who has been in a car accident will be 0.3238
Number of people that indicated that they had been in a car accident = 215 respondents
Number of people that said that they had not been in a car accident = 449
The probability of getting someone who has been in a car accident will then be calculated as:
= 215/664
= 0.3238
Therefore, the probability of getting someone who has been in a car accident will be 0.3238

What is the unit rate for 4543.08 km in 52.4 h? Enter your answer, as a decimal, in the box. km/h
Final answer:
The unit rate, or average speed, for traveling 4543.08 km in 52.4 hours is calculated by dividing the distance by the time, resulting in an average speed of 86.70 km/h.
Explanation:
The question asks for the unit rate of 4543.08 km traveled in 52.4 hours, which is essentially asking for the average speed in kilometers per hour (km/h). To find this, you would divide the total distance traveled by the total time taken.
Mathematically, this is expressed as:
Distance (km) / Time (h) = Speed (km/h)Substituting the given values:
4543.08 km / 52.4 h = 86.70 km/hTherefore, the unit rate or average speed is 86.70 km/h. It's important to note that when calculating such problems, it's essential to maintain consistency in the units (in this case, km for distance and hours for time) to ensure the accuracy of your result.

The perimeter of a church window is 80 inches. If the window is in the shape of a square.what is the length of each side of the window?
The length of each side of the church window is 20 inches.
Explanation:To find the length of each side, we need to determine the perimeter of the square. The perimeter is the sum of all four sides of the square. In this case, it is given that the perimeter is 80 inches. Since all sides of a square are equal in length, we can divide the perimeter by 4 to find the length of each side. So, each side of the church window will be 80 inches divided by 4, which is 20 inches.
