An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
2m - 5q = 8
4m + 2q = 64
The value of q in the solution to the equations is 4.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
2X = 4 is an equation.
We have,
2m - 5q = 8 ____(1)
4m + 2q = 64 _____(2)
From (1) we get,
2m = 8 + 5q
Divide both sides by 2.
m = (8 + 5q)/2 ______(3)
Now,
Putting (3) in (2) we get,
4m + 2q = 64
4/2 (8 + 5q) + 2q = 64
2 (8 + 5q) + 2q = 64
16 + 10q + 2q = 64
16 + 12q = 64
12q = 64 - 16
q = 48/12
q = 4
Now,
q = 4 in (3) we get,
m = (8 + 5q) / 2
m = (8 + 5 x 4) / 2
m = (8 + 20) / 2
m = 28 / 2
m = 14
Thus,
The value of q in the solution to the equations is 4.

Help !! Solve for all values of x in simplest form. Its in the picture!!☝☝☝
The point where the graphs of two equations intersect has y-coordinate 2. One equation is y=−3x+5 . Complete the other equation in the form y=mx+b if its graph has a slope of 1.
Answer:
y = x + 1
Step-by-step explanation:
y = -3x + 5
Let y = 2
2 = -3x +5
-3 = -3x
x = 1
(1, 2)
y = mx + b
y = 1x + b
2 = 1 + b
b = 1
Therefor, the other one is, y = x + 1
Which equation best represents the relationship between x and y in the graph?
Answer:
Y=1/2x+2
Step-by-step explanation:
The 2 is crossing the y-axis not the x so it crosses out the first two equations and the third one wouldn't work because -4 is through the x-axis meaning it can't be b.

graph a line that contains the point (3,-6) and has slope of -1/2
Answer:
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y intercept
Since, m = -[tex]\frac{1}{2}[/tex]
Equation of the line will be,
y = [tex]-\frac{1}{2}x+b[/tex]
Since, a point (3, -6) lies on the line,
-6 = [tex]-\frac{3}{2}+b[/tex]
b = -6 + 1.5
b = -4.5
Equation of the line will be,
[tex]y=-\frac{x}{2}-\frac{9}{2}[/tex]
Table for the points on the graph,
x -4 -3 -2 -1 0
y -2.5 -3 -3.5 -4 -4.5
Plot these points and join them to get the graph of a line.

Answer:
Step-by-step explanation:
p-1=5p+3p-8
7=7p
p=1
Answer:
p = 1
Step-by-step explanation:
[tex]p-1 = 5p + 3p - 8[/tex]
combine like terms on the right side
[tex]p - 1 = 8p - 8[/tex]
subtract 8p from both sides
[tex]-7p - 1 = -8[/tex]
add 1 to both sides
[tex]-7p = -7[/tex]
divide both sides by -7
[tex]p = 1[/tex]
y = 3x + 4
state the slope and the y-intercept for the graph of each equation
Answer:
3x = slope
4 = y-intercept
Step-by-step explanation:
Actual formula: y = mx + b
where m = slope
b = y-intercept
Equation given: y = 3x + 4
In this case the "3x" is the slope
And the "4" is the y-intercept (it never changes as well)

Write a function to represent each series of transformations:
• rotation of 90 degrees counterclockwise about the origin, point O, then a reflection across the x-axis
• reflection across the y-axis, then a translation a units to the right and b units up
• translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection across the y-axis
Answer:
Step-by-step explanation:
For the first one, I believe you would need to use a rotation matrix; to rotate 90º counterclockwise, the matrices would look like ; you would then multiply those out. A reflection across the x-axis would be changing the sign of f(x) (from negative to positive or positive to negative), a reflection across the y-axis would be changing the sign of x, translation a units to the right would be subtracting a from x, translation b units up would be adding b to x. Rotation of 180º about the origin would be the same format as the first matrix, except it would be cos180 and cos0 on the top and sin180 sin0 on the bottom. Reflection across the y-axis would be changing the sign of x again.
OR
1. We know that, 'Translation shifts the figure in any direction'.
As, the function f(x) is translated 'a' units to the right, the new form of function is f(x-a).
Again, the function is translated 'b' units up, the final form of the function is f(x-a)+b.
2 and 3. We know that, ' Reflection flips the image over a line'.
As the function g(x) is reflected over y-axis, the new form of the function is g(-x).
As the function h(x) is reflected over x-axis, the new form of the function is -h(x).
4 , 5 and 6. We know that, 'Rotation turns the image around a point to a certain degree'.
Let us assume the function to be a point (x,y).
As the function is rotated by 90° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{90}R
90
(x,y) = ( -y,x ).
As the function is rotated by 180° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{180}R
180
(x,y) = ( -x,-y ).
As the function is rotated by 2700° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{270}R

PARKING Stephanie is drawing the layout of a parking lot on a coordinate grid and needs to verify that two
sides meet in a right angle. In her sketch, one side of the parking lot has endpoints A(0,0) and B(50,0). The
second side of the parking lot has endpoints B(50,0) and C(18, 24). How can Stephanie prove that the two
sides of the parking lot meet in a right angle? Select all that apply.
® Find the slopes of AC and CB. If the product of the slopes is -1, then the sides meet in a right angle.
B Find the slopes of AB and AC. If the product of the slopes is -1, then the sides meet in a right angle.
© Find the slopes of CB and AB. If the slope of AB is the opposite of the slope of AC, then the sides meet in
a right angle.
Find AB, BC, and AC. If AB + BC = AC, then the sides meet in a right angle.
Find AB, BC, and AC. IfAB2+ BC = AC?, then the sides meet in a right angle.
Answer:
The answer is: Find the slopes of AB and AC. If the product of the slopes is -1, then the sides meet in a right angle.
Step-by-step explanation:
From Analytical Geometry, two lines are perpendicular to each other if and only if [tex]m_{1}\cdot m_{2} = -1[/tex], where [tex]m_{1}[/tex] and [tex]m_{2}[/tex] are the slopes of each line, respectively. According to this, the following expression must be observed:
[tex]m_{AB} \cdot m_{BC} = -1[/tex] (1)
Each slope can be determine by definition of the slope of a Secant Line:
[tex]m_{AB} = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}[/tex] (2)
[tex]m_{BC} = \frac{y_{C}-y_{B}}{x_{C}-x_{B}}[/tex] (3)
Where:
[tex]x_{A}[/tex], [tex]x_{B}[/tex], [tex]x_{C}[/tex] - x-Coordinates of points A, B and C.
[tex]y_{A}[/tex], [tex]y_{B}[/tex], [tex]y_{C}[/tex] - y-Coordinates of points A, B and C.
If we know that [tex]x_{A} = 0[/tex], [tex]y_{A} = 0[/tex], [tex]x_{B} = 50[/tex], [tex]y_{B} = 0[/tex], [tex]x_{C} = 18[/tex] and [tex]y_{C} = 24[/tex], then the relationship between slopes is:
[tex]m_{AB} = \frac{0-0}{50-0}[/tex]
[tex]m_{AB} = 0[/tex]
[tex]m_{BC} = \frac{24-0}{18-50}[/tex]
[tex]m_{BC} = -\frac{3}{4}[/tex]
[tex]m_{AB}\cdot m_{BC} = 0\cdot \left(-\frac{3}{4} \right)[/tex]
[tex]m_{AB}\cdot m_{BC} = 0[/tex]
Which means that both line segments are not perpendicular to each other.
In a nutshell, we need to find the slopes of AB and CB, if the product between both slopes is -1. Then, the sides meet in a right angle.
