Answer: No, it is not a solution
==========================================================
Explanation:
The point (3,-4) means that x = 3 and y = -4 pair up together
Let's plug these x,y values into each equation
Starting with the first equation, we get,
y = 4x-16
-4 = 4(3)-16 ... x replaced with 3; y replaced with -4
-4 = 12-16
-4 = -4 .... this is a true statement
Repeat for the second equation
y = 2x-6
-4 = 2(3)-6
-4 = 6-6
-4 = 0 ... this is false
Since we get a false statement, this means (3,-4) is not on the line y = 2x-6, which means that overall (3,-4) is not a solution to the system of equations. The point (3,-4) must make both equations true for it to be a solution.
What is the solution to the equation below?
4w = 2/3
A. W = 2/12
B. W = 2/7
C. W = 8/3
D. W = 3 1/3

Triangles P and Q are similar.
Find the lengths of the sides:
The diagram is not drawn to scale.
Answer:
I don't know if im correct but the missing side on P is 9 and the missing side on Q is 28? Sorry if im wrong
Step-by-step explanation:
4x __ =16cm
16÷4 =4
7x 4 = 28cm
36÷4= 9cm
P= 9cm
Q= 28cm
Length of XZ is 28 and length of CB is 9.
What are similar Triangles?Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
In similar triangles, corresponding sides are always in the same ratio.
By the given figure ABC and XYZ,
We check the ratios of corresponding sides
XY/AB=YZ/CB=XZ/AC
16/4=36/CB=XZ/7
4=36/CB=XZ/7
Now equate the equation to get the unknown lengths.
4=36/CB
CB=36/4
=9
So CB=9
XZ/7=4
XZ=28
So lengths of XZ is 28 and length of CB is 9.

If x = 12 and y = 3, what is the value
of |-x + 5y|?
Answer:
3
Step-by-step explanation:
First, let's solve whats in the absolute value. If wee plug in the values of x and y, we get -(12) + 5(3) which is -12 + 15. This equals to 3. Now concerning the absolute value, it makes the value inside it always positive. And since the answer is positive, that means it remains the same.

Beverly is painting a mural on a 1-square-meter section of a wall. She has completed a rectangular part of the mural that's is 5/6 meter wide and 1/4 meter long. What part of the mural have Beverly completed.
Answer:
0.21 square meter
Step-by-step explanation:
Area of the section of wall = 1 square meter
Dimension of part of mural completed = [tex]\frac{1}{4}[/tex] meter by [tex]\frac{5}{6}[/tex] meter
Part of the mural completed = Area of the rectangular part of mural completed
But,
Area of a rectangle = length x width
So that,
Part of the mural completed = length x width
= [tex]\frac{1}{4}[/tex] x [tex]\frac{5}{6}[/tex]
= [tex]\frac{5}{24}[/tex]
= 0.2083
Part of the mural completed = 0.21 square meter
The part of the mural that has been completed by Beverly is 0.21 square meter.
