The system of equations shown below is graphed on a coordinate grid:
3y + x = 4
2y − x = 6
Which statement is true about the coordinates of the point that is the solution to the system of equations?
It is (−2, 2) and lies on both lines.
It is (−5, 3) and lies on both lines.
It is (−5, 3) and does not lie on either line.
It is (−2, 2) and does not lie on either line.
Let's solve your system by substitution.
3y+x=4;2y−x=6
Rewrite equations:
x+3y=4;−x+2y=6
Step: Solvex+3y=4for x:
x+3y=4
x+3y+−3y=4+−3y(Add -3y to both sides)
x=−3y+4
Step: Substitute−3y+4forxin−x+2y=6:
−x+2y=6
−(−3y+4)+2y=6
5y−4=6(Simplify both sides of the equation)
5y−4+4=6+4(Add 4 to both sides)
5y=10
5y
5
=
10
5
(Divide both sides by 5)
y=2
Step: Substitute2foryinx=−3y+4:
x=−3y+4
x=(−3)(2)+4
x=−2(Simplify both sides of the equation)
Answer:
x=−2 and y=2
Your line would also lay on both lines so the answer would be the first one: It is (−2, 2) and lies on both lines.

Find the median of the following number of points deducted from a random sample of algebra
midterms.
12, 14,0, 2, 17,7,3, 14, 15
Answer:
[tex]\boxed {\boxed {\sf Median: 12}}[/tex]
Step-by-step explanation:
The median is the middle number of a data set.
1. Arrange the data in ascending order (least to greatest)
Data Set: 12, 14, 0, 2, 17, 7, 3, 14, 15 Least to Greatest: 0, 2, 3, 7, 12, 14, 14, 15, 172. Take one number off each end of the data until the middle is reached.
0, 2, 3, 7, 12, 14, 14, 15, 172, 3, 7, 12, 14, 14, 153, 7, 12, 14, 147, 12, 14 12The median of this data set is 12
12 is the median of given data.
Solution :Given data : 12, 14, 0, 2, 17, 7, 3, 14, 15
The middle term of data in ascending order is it's median.
First of all, arrange the data in ascending order.
Ascending order : 0, 2, 3, 7, 12, 14, 14, 15, 17
Now, count total number of terms in given data :
Here, total number of terms, n = 9.
As, we have total number of terms as a odd number.
So, by applying formula :
[tex] \large \underline{\boxed{\sf{Median = \dfrac{n+1}{2} th \: term}}}[/tex]
[tex] \sf : \implies Median = \dfrac{9+1}{2} th \: term[/tex]
[tex] \sf : \implies Median = \dfrac{\cancel{10}^{5}}{\cancel{2}} th \: term[/tex]
[tex] \sf : \implies Median = 5 th \: term[/tex]
Now, let's count 5th term :
0, 2, 3, 7, 12, 14, 14, 15, 17
Here, 5th term is 12.
So, The median of this data is 12.

Step-by-step explanation:
What is the length of the line segment AB is point A is (12, -2) and B is (-4, -8)? Round to the nearest tenth.
Answer:
The length of the line segment AB is 17.1
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We are given the points A(12,-2) and B(-4,-8). Applying the formula:
[tex]d=\sqrt{(-4-12)^2+(-8+2)^2}[/tex]
[tex]d=\sqrt{(-16)^2+(6)^2}[/tex]
[tex]d=\sqrt{256+36}=\sqrt{292}[/tex]
d = 17.1
The length of the line segment AB is 17.1

Answer:
The required equation is: [tex]\mathbf{4x+1=2x-6}[/tex]
Step-by-step explanation:
We need to translate the statement into an equation
Let x represent the unknown number.
The sum of four times a number and 1 is equal to the difference of twice the number and 6.
I am breaking down step by step to make the equation:
Four times a number : 4x
The sum of four times a number and 1: 4x+1
Twice the number: 2x
The difference of twice the number and 6: 2x-6
So, the final equation will be:
[tex]4x+1=2x-6[/tex]
So, the required equation is: [tex]\mathbf{4x+1=2x-6}[/tex]

Apply The Remainder Theorem, Fundamental Theorem, Rational Root Theorem, Descartes Rule, and Factor Theorem to find the remainder, all rational roots, all possible roots, and actual roots of the given function. Make Sure to graph the function and state the turning points (Relative maximum and relative minimum) and end behavior (Graph is rising or falling on the right or left side, etc.)
f(x) = 3x^3 − x^2 + 8x + 12
Please answer all the questions fully asap!!
9514 1404 393
Answer:
possible rational roots: ±{1/3, 2/3, 1, 4/3, 2, 3, 4, 6, 12}
actual roots: -1, (2 ±4i√2)/3
no turning points; no local extrema
end behavior is same-sign as x-value end-behavior
Step-by-step explanation:
The Fundamental Theorem tells us this 3rd-degree polynomial will have 3 roots.
The Rational Root Theorem tells us any rational roots will be of the form ...
±{factor of 12}/{factor of 3} = ±{1, 2, 3, 4, 6, 12}/{1, 3}
= ±{1/3, 2/3, 1, 4/3, 2, 3, 4, 6, 12} . . . possible rational roots
Descartes' Rule of Signs tells us the two sign changes mean there will be 0 or 2 positive real roots. Changing signs on the odd-degree terms makes the sign-change count go to 1, so we know there is one negative real root.
The y-intercept is 12. The sum of all coefficients is 22, so f(1) > f(0) and there are no positive real roots in the interval [0, 1]. Synthetic division by x-1 shows the remainder is 22 (which we knew) and all the quotient coefficients are all positive. This means x=0 is an upper bound on the real roots.
The sum of odd-degree coefficients is 3+8=11, equal to the sum of even-degree coefficients, -1+12=11. This means that -1 is a real root. Synthetic division by x+1 shows the remainder is zero (which we knew) and the quotient coefficients alternate signs. This means x=-1 is a lower bound on real roots. The quotient of 3x^2 -4x +12 is a quadratic factor of f(x):
f(x) = (x +1)(3x^2 -4x +12)
The complex roots of the quadratic can be found using the quadratic formula:
x = (-(-4) ±√((-4)^2 -4(3)(12)))/(2(3)) = (4 ± √-128)/6
x = (2 ± 4i√2)/3 . . . . complex roots

The graph in the third attachment (red) shows there are no turning points, hence no relative extrema. The end behavior, as for any odd-degree polynomial with a positive leading coefficient, is down to the left and up to the right.

Given:
A figure.
To find:
The angle number which is supplementary to ∠OKL.
Solution:
The angles which lie on the same side of a straight line and their sum is 180 degrees, then they are called supplementary angles.
From the given figure it is clear that ∠OKL is lies on the intersection point K of lines OJ and GL.
[tex]\angle OKL=\angle 12[/tex]
Angle 11 and angle 12 lie on the same side of the straight line GL.
So, angle 11 and angle 12 are supplementary angles.
Therefore, angle 11 is supplementary to ∠OKL.

Currently, Vanessa is twice as old as Chris. Eight years ago, Vanessa was six times as old as Chris. How old is Chris now?
Answer:
Chris is currently 10
Step-by-step explanation:
I'll be honest, I looked this up so sorry for stealing the points, but use the letter v to represent vanessa and c for chris
If vanessa is twice chris' age, then v=2c
Your other equation would be (v-8)=6(c-8)
Use these two equations to solve for c through a system of equations and get c = 10 or Chris' current age is 10
Answer:
Currently, Chris is 10 years old. Vanessa is 20.
Step-by-step explanation:
2x = 6x - 8, so x = 2. Meaning Chris was 2 years old 8 years ago. So if Chris was 2, that means Vanessa was 12. Add 8 to both sides, 2 + 8 and 12 + 8, we get the result of Chris being 10, and Vanessa is 20. Which does fit the twice as old part.

how can 12 people share 7 apples so that each apple is cut into equal pieces only and into no more than 4 pieces? It also must be fair!
Answer:
1.75 or 1 3/4 pieces each
Step-by-step explanation:
3 pieces per apple x 7 = 21
21/12 = 1.75
The solution is 1/4 + 1/3 = 7/12
The number of apples is shared among 12 people is given by the equation A = ( 1/4 ) + ( 1/3 ) = 7/12
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Let the number of apples be = 7 apples
Let the number of people be = 12 people
Now , let the number of apples each person gets be A = number of apples / number of people
Substituting the values in the equation , we get
Number of apples each person gets be A = 7/12
Now , the value 7/12 is represented as A = 1/12 + 6/12
And, cut 4 apples into thirds and cut 3 apples into fourths
Substituting the values in the equation , we get
A = ( 1/4 ) + ( 1/3 ) be equation (1)
On simplifying the equation , we get
A = ( 3 + 4 ) / ( 3 x 4 )
A = 7 / 12
Therefore , the value of A is 7/12
Hence , the number of apples shared is A = ( 1/4 ) + ( 1/3 )

The sale price is 90% of the original price.
Step-by-step explanation:
The original price is 100% of the original price. If 10% of the original price is subtracted, the new price is 100% - 10% = 90% of the original price.
The sale price is 90% of the original price.
