Solve this system of equations by graphing. First graph the equations, and then type the solution. y=2x+2 y=x–2
Solution:
The equation of a straight line is in the form y = mx + b, where m is the slope of the graph and b is the y intercept (value of y when x = 0). To graph the line, online geogebra graphing calculator was used for plotting the two graphs by writing the equation of the graphs.
After plotting the two graphs, the intersection of the two lines should be traced to get the x coordinate and y coordinate of the point. This point is the solution of the two graph equations, hence:
The solution = (-4, -6)
Answer:
(-4-6)

Can you find the slope-intercept equation of each line and type the correct code? Please remember to type in ALL CAPS with no spaces.
Answers
Answer:
The answer for the code is CGIA
Step-by-step explanation:
The slope- intercept of each line is
First line,y= x+ 2
Second line,y = 2x +2
Third line,y= -x +1
Fourth line,y= -2x - 2
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
First line,
slope intercept form
(y - 3)= 1(x-1)
y= x+ 2
Second line,
slope intercept form
(y - 2)= 2(x-0)
y = 2x +2
Third line,
slope intercept form
(y + 2)= (-1)(x - 3)
y= -x +1
Fourth line,
slope intercept form
(y + 2 )= -2(x-0)
y= -2x - 2

Factorise x² - x with explanation please?
Answers
Answer:
x(x + 1)
Step-by-step explanation: This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1)

Your friend really wants to buy the newest coolest cell phone which will cost him $310 he gets a job detailing cars and suvs and plans to save all the money he earns if he gets paid $60 to detail a car and $85 to detail an suv which of the following inequalities can be used to determine how many of each he must detail in order to earn at least $310
Answers
Answer:
[tex]60c + 85s \geqslant 310[/tex]
Step-by-step explanation:
He needs to earn at least $310 so $60 per car is 60c and $85 per SUV is 85s. So the answer is the third option.
The required inequality:
60x + 85y >= 310
What is inequality?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given, a person gets paid $60 to detail a car and $85 to detail an SUV.
Let's assume he needs to detail x number of cars and y number of SUVs to earn at least $310.
Then, the amount earned by detailing x cars and y SUVs can be expressed as:
60x + 85y
According to the problem statement, he wants to earn at least $310, so we can write the inequality:
60x + 85y >= 310
This is the required inequality to determine the number of cars and SUVs he needs to detail in order to earn at least $310.

Answer:
10
Step-by-step explanation:
You would do something called KCF Keep, Change, and Flip.
You would keep the 7 1/2 and change the divided sign to multiplying sign and flip the 3/4 so its a 4/3 and then multiply it.
15/6 times 4/3. 15 x 4 = 60
2x3= 6
so I can be 60/6 but you would simplify and 6 goes into 60 10 times. so 10 is you answer
