Answer:
[tex]\frac{6}{5}[/tex] x + [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Add the x- terms together
[tex]\frac{3}{5}[/tex] x + [tex]\frac{3}{5}[/tex] x + [tex]\frac{2}{5}[/tex]
= [tex]\frac{6}{5}[/tex] x + [tex]\frac{2}{5}[/tex]

a. Find the slope of the line.
Answer:
Slope = -4
x intercept = 3
Step-by-step explanation:
See attachment for graph
Required
a. Determine the slope
b. Find the x intercept and explain what it represents
a. The slope
To calculate the slope, we start by selecting any two corresponding values of x and y from the graph.
[tex](x_1,y_1) = (3,0)[/tex]
[tex](x_2,y_2) = (0,12)[/tex]
Next, we calculate the slope (m)
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
[tex]m = \frac{0 - 12}{3 - 0}[/tex]
[tex]m = \frac{- 12}{3}[/tex]
[tex]m = -4[/tex]
b. The x intercept
This is the point where [tex]y = 0.[/tex]
From the graph.
[tex]x = 3[/tex] when [tex]y = 0[/tex]
This implies that:
After 3 hours, the distance left to cover is 0miles.
In other words, she arrived home in 3 hours

P(-2)=1 P(-1)=3 P(1)=0 P(2)=4
What is the remainder when P(x) is divided by (x - 1)?
Answer:
The remainder is 0
Step-by-step explanation:
Polynomial Remainder Theorem
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).
We are given the values of P for various values of x as follows:
P(-2)=1
P(-1)=3
P(1)=0
P(2)=4
Applying the polynomial remainder theorem, finding the remainder when P(x) is divided by x-1 is just finding P(1).
Since P(1) = 0, the remainder is 0

Are lines L1 and L2 perpendicular??
How do I explain and justify it ?
Please help me
Answer:
No.
Step-by-step explanation:
Perpendicular in the dictionary means: at an angle of 90° to a given line, plane, or surface. Those lines do not create a square angle, as the points of the lines do not match up, so it will not create a right angle. (90°)
PLEASE HELP ME OUT I DONT UNDERSTAND
Answer:
(b) and (c)
Step-by-step explanation:
When the equation of a line is given in slope-intercept form ([tex]y=mx+b[/tex]), m represents the slope of the line and b represents the y-intercept. As we can see, the two lines given have the same slope (-3), but different y-intercepts (the first line has a y-intercept of 4 and the second line has a y-intercept of -11).
Since the slopes of the two lines are the same, they will be parallel, and since their y-intercepts are different, they will not be the same line. Therefore, the two lines will not intersect (a solution to the system is any point where the two lines do intersect), and there is no solution to the system.
As a general rule:
If two lines have different slopes, there will be exactly one solution to the system (the lines will not be parallel and will intersect at exactly one place)If two lines have the same slope, and the same y-intercept, there will be infinitely many solutions (the two lines will be the same, and any point on the line will be a solution)If two lines have the same slope, but different y-intercepts, they will be parallel and will never intersect, so there will be no solution.Pls take a pic of what steps you did if you can, find x!

Isosceles triangle
Solve:
3(x - 2) = 12
Answer:
x=6
Step-by-step explanation:
3(x-2)=12
divide both sides by 3
x-2=4
add 2 to both sides
x-2+2=4+2
combine like terms
x=6
Answer:
x = 6
Step-by-step explanation:
So the equation looks like this:
3(x - 2) = 12
So the first thing we are going to do in this equation is multiply 3 by x and -2 in order to get rid of the parenthesis:
3(x - 2) = 12
(3 * x) + (3 * (-2)) = 12
3x - 6 = 12
Now we are going to add 6 to -6 and what you to one side of the equation you do to the other:
3x - 6 = 12
+ 6 + 6
3x = 18
Now in order to segregate the variable x from 3 we are going to have to divide 3x by 3 and what you do to one side of the equation you do to the other:
3x/3 = 18/3
x = 6
Now in order to check our work we are going to replace the variable x with six in the equation:
3(x - 2) = 12 = 3((6) - 2) = 12
(3 * 6) + (-2 * 3) = 12
18 - 6 = 12
12 = 12
Tada, hope this helps you!!

Answer:
Only X-1
Step-by-step explanation:
[tex]f(x) = x + 5x + 2x - 8 \\ f(x) = 8x - 8 \\ let \: x = 1 \: be \: the \: root \: of \: f(x) \\ f(1) = (8 \times 1) - 8 = 0 \\ hence \: 1 \: is \: the \: root \: of \: the \: equation \\ therefore \: x = 1 \\ x - 1 = 0 \\ hence \: x - 1 \: is \: the \: fator \: of \: f(x)[/tex]

Answer:
7 [tex]\frac{1}{2}[/tex] miles
Step-by-step explanation:
The problem above is under the topic, "Subtracting Mixed Numbers with Similar Fractions."
In order to find the answer, you have to subtract the whole number parts first.
12-5 = 7
Then, you have to subtract the fractional parts. All you have to do is to get the difference of the numerators and copy the denominator.
7/8 - 3/8 = [tex]\frac{4}{8}[/tex]
Therefore, 12 [tex]\frac{7}{8}[/tex] - 5 [tex]\frac{3}{8}[/tex] = 7 [tex]\frac{4}{8}[/tex] miles
Let's simplify: 7 [tex]\frac{1}{2}[/tex] miles
David biked 7 [tex]\frac{1}{2}[/tex] miles farther on Tuesday than on Wednesday.
