First of all we need to find the equations of the lines :
y( red ) = - x + 2
y(blue) = 2x - 1
Then we must to put the equations equal to each other and going to to find the value of x :
[tex]- x + 2 = 2x - 1[/tex]
Add both sides x
[tex] - x + x + 2 = 2x + x - 1[/tex]
[tex]2 = 3x - 1[/tex]
Add both sides 1
[tex]2 + 1 = 3x - 1 + 1[/tex]
[tex] 3 = 3x[/tex]
Switch sides
[tex]3x = 3[/tex]
Divide both sides by 3
[tex] \frac{3x}{3} = \frac{3}{3} \\ [/tex]
[tex]x = 1[/tex]
After u the value of x , put it in one the equations to find the value of y :
[tex]y = - x + 2[/tex]
[tex]y = - (1) + 2[/tex]
[tex]y = - 1 + 2[/tex]
[tex]y = 1[/tex]
Thus the solution is ( 1 , 1 ) .

Answers
A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.
How many inches in one centimeter?A centimeter is a unit to measure a length in the metric system. One centimeter is equal to 0.39 inches.
It is given that
3.25 cm length of rope weighs 61.40 grams.
There are 28.3495 grams in an ounce.
There are 2.54 centimeters in an inch.
a = b
c = x
So x = cb / a
If there are 2.54 centimeters in 1 inch,
centimeters= 19.45 × 2.54/ 1 inch
centimeters= 49.403
Now, if 3.25 centimeters long weighs 61.40 grams, then
grams= 49.403 × 61.40 / 3.25 centimeters
grams= 933.34
Finally, if there are 28.3495 grams in 1 ounce,
ounces= 933.34 × 1 ounce / 28.3495 grams
ounces= 32.92
Thus, A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.

Answers
The functions have a vertex with a x-value of 0 will be f(x) = |x|,f(x) = |x|+ 3 and f(x) = |xl - 6.Option 1,2 and 4 are functions have a vertex with a x-value of 0.
What is a function?A connection between independent variables and the dependent variable.is defined by the function. Functions help to represent graphs and equations.
The standard absolute value function is found as;
[tex]\rm f(x) = a|x - h| + k[/tex]
Where,
(h, k) denotes to the vertex
h is the vertex of the x-coordinate
k is the y-coordinate of the vertex
By comparing the standard equation with the given equation in the options we will get the functions to have a vertex with an x-value of 0;
[tex]\rm f(x) = |x| \\\\ \rm f(x) = |x| + 3 \\\\ f(x) = |x| - 6[/tex]
The functions have a vertex with a x-value of 0 will be f(x) = |x|,f(x) = |x|+ 3 and f(x) = |xl - 6.Option 1,2 and 4 are functions have a vertex with a x-value of 0.

The equation of the line that is parallel to the line y = 4x + 13 and passing through the point (4, 32) will be y = 4x + 16. Then the correct option is D.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The equation of the line is given below.
y − 1 = 4(x + 3)

3y−3x=15
Answers
__________________________________________________________
Hello! In this question, we will be changing our given equation to turn it into slope-intercept form.
__________________________________________________________
Explanation:
We are given the following equation:
3y − 3x = 15
Our goal is to turn the equation into slope-intercept form, which is:
y = mx + b
Let us rearrange the equation and simplify it:
3y − 3x = 15
Add 3x to both sides, which would cancel the 3x on the left.
3y = 3x + 15
Now, divide everything by 3 to get the "y" variable by itself.
y = x + 5
Therefore, your simplified equation in slope-intercept form would be:
y = x + 5
__________________________________________________________
Answer:
y = x + 5
__________________________________________________________
Part I: Reviewing the slope intercept form equation
Given equation:
3y - 3x = 15Slope intercept form: y = mx + b
[Where "m" is the slope and "b" is the y-intercept]
Part II: Isolating "y" and it's cooeficient on one side of the equation
In the slope intercept form equation, we can see that the "y" variable is completely isolated on one side of the equation. Therefore,
⇒ 3y - 3x = 15⇒ 3y - 3x + 3x = 15 + 3x⇒ 3y = 3x + 15Part III: Isolating "y" from it's cooeficient
The "y" variable in the slope intercept form has no cooeficient. Therefore, we need to isolate the cooeficient of "y" in our equation ( 3y = 3x + 15 ). This can be done by dividing 3 both sides or multiplying 1/3 both sides.
⇒ 3y/3 = (3x + 15)/3⇒ y = (3x + 15)/3Part IV: Simplify the other side of the equation
Finally, simplify the other side to obtain our equation in slope intercept form.
⇒ y = 3x/3 + 15/3⇒ y = x + 5Therefore, the equation in slope intercept form is y = x + 5.

Answers
A=6500×(1+0.04)^2
The equation represents how much will be in the account after 2 years will be A = $6,500 + ($6,500 x 4 x 2)/100.
What is simple interest?Let P be the principal, R be the rate of interest, and T be the time. Then the interest rate is given as,
I = (PRT)/100
6,500 dollars is placed in a savings account with an annual interest rate of 4%.
Then the amount after 2 years is calculated as,
A = P + I
A = P + PRT / 100
A = $6,500 + ($6,500 x 4 x 2)/100
Thus, the equation will be A = $6,500 + ($6,500 x 4 x 2)/100.
