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 ) .

Faith wants to add a 20% tip to a $56 restaurant bill. How much will Faith pay including the tip?
Answer:
67.20$
Step-by-step explanation:
multiply 56 by 1.2
Answer:
$67.2
Step-by-step explanation:
Given:
Price = $56Tip = 20%∴ Equation: Price + Tip = Total
⇒ 56 + (20/100 × 56) = TotalSimplify the equation to obtain the total:
⇒ 56 + (20/100 × 56) = Total⇒ 56 + (20/50 × 28) = Total⇒ 56 + (20/25 × 14) = Total⇒ 56 + (4/5 × 14) = Total⇒ 56 + (56/5) = TotalConvert the expression in the parenthesis into decimals:
⇒ 56 + (56/5) = Total⇒ 56 + (11.20) = TotalOpen the parenthesis and simplify:
⇒ 56 + 11.20 = Total⇒ $67.2 = TotalFaith will pay (including the tip) $67.2.

Answer: d, the diameter, is about 36.92 units
Step-by-step explanation:
The c value is the circumference and we are being asked to solve for the diameter.
We can take the value they give for the circumference, plug it into the circumference formula, and solve for d. Please note that the diameter is two times the radius, or r, so at the end I will multiply r by two.
C = 2πr
(116) = 2πr
18.46 ≈ r
r ≈ 18.46
-
18.46 * 2 = 36.92
The missing measure is about 36.92 units.

The trinomial x2 bx – c has factors of (x m)(x – n), where m, n, and b are positive. what is the relationship between the values of m and n? explain.
The relationship between the values of m and n for the trinomial x²+bx -c is (m+n) is the sum of the roots and (mn) is the product of the roots.
What is trinomial?A trinomial is the type of algebraic expression in which there are three terms present and more than one variable are present.
The trinomial given in the problem is,
[tex]x^2 +bx - c[/tex]
This trinomial has factors of,
[tex](x +m)(x - n),[/tex]
Where m, n, and b are positive.
If this factors multiply by each other, we get,
[tex](x +m)(x - n)\\x^2+nx+mx+nm\\x^2+(n+m)x+nm[/tex]
Compare it with the trinomial, we get,
[tex]b=(m+n)[/tex]
Which is the sum of the terms,
[tex]c=nm[/tex]
Which is the product of the terms.
Hence, the relationship between the values of m and n for the trinomial x²+bx -c is (m+n) is the sum of the roots and (mn) is the product of the roots.

A rope has a density and thickness such that a 3.25-centimeter-long segment of it weighs 61.40 grams. there are 28.3495 grams in an ounce and 2.54 centimeters in an inch. how many ounces would a 19.45 inch length of the same rope weigh? a. 5.10 oz b. 11.49 oz c. 32.92 oz d. 53.90 oz
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.

Which functions have a vertex with a x-value of 0? select three options. f(x) = |x| f(x) = |x| 3 f(x) = |x 3| f(x) = |x| − 6 f(x) = |x 3| – 6
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)
The equation can be written as
y = 4x + 13
Then the equation of the line that is parallel to the line y = 4x + 13 and passing through the point (4, 32) will be
The slope of the parallel lines will be the same
Slope = 4
Then
y = 4x + c
The line is passing through (4, 32)
32 = 4(4) + c
32 = 16 + c
c = 16
