Answers
The equations that could represent the graph shown are:
A. -4x + 2y = -6
C. y = 3x - 2
How to Determine the Equation of a Graph?The equation of a linear graph, in slope-intercept form, can be written as y = mx + b, where:
b is the point on the y-axis that the line intercepts, which is called the y-intercept of the graph.m is the slope of the graph, which is the rise/run along the line.Given the graph in the diagram, it would have a positive slope and a negative y-intercept.
A. -4x + 2y = -6
Rewrite in slope-intercept form
2y = 4x - 6
y = 4x/2 - 6/2
y = 2x - 3 [positive slope and negative y-intercept]
B. 2x - 3y = -9
Rewrite in slope-intercept form
-3y = -2x - 9
y = 2/3x + 3 [positive slope and positive y-intercept]
C. y = 3x - 2 [positive slope and negative y-intercept]
D. y = -10 is a horizontal line.
Therefore, the equations that could represent the graph shown are:
A. -4x + 2y = -6
C. y = 3x - 2

A regular pentagon has a side length of 2x+9. A square has a side length of 3x
Answers
The possible solution for x can be 22.5.
We are given that the side of the regular pentagon = 2 x + 9
So, the perimeter will be:
P ( Regular pentagon) = 5 × ( 2 x + 9 )
P ( Regular pentagon) = 10 x + 45
Also, we are given that the side of a square is 3 x
Perimeter will be:
P ( square) = 4 × 3 x
P ( square) = 12 x
Now, we are given that P ( Regular pentagon) = P ( square)
So, we get that:
10 x + 45 = 12 x
12 x - 10 x = 45
2 x = 45
x = 45 / 2
x = 22.5
Therefore, the possible solution for x can be 22.5.

add the 2 numbers and divide by 2
4x+12y+4z=-16
12x-12y+8z=8
4x+12y-4z=0
Answers
x = 1, y = -1 and z = -2.
Here, we are given 3 equations-
4x+12y+4z = -16 ...(1)
12x-12y+8z = 8 ...(2)
4x+12y-4z = 0 ...(3)
Firstly, we add equations 1 and 2, we get,
4x + 12y + 4z + 12x - 12y + 8z = -16 + 8
16x + 12z = -8
4x + 3z = -2 ...(4)
Adding 2 and 3, we get,
12x - 12y + 8z + 4x + 12y - 4z = 8
16x + 4z = 8
4x + z = 2 ...(5)
Now, subtracting equation 4 from 5, we get-
4x + z - 4x - 3z = 2 + 2
-2z = 4
z = 4/-2
z = -2
Thus, 4x - 2 = 2
4x = 4
x = 4/4
x = 1
and 4(1) + 12y + 4(-2) = -16
4 + 12y -8 = -16
12y = -16 + 4
12y = -12
y = -12/12
y = -1
Thus, x = 1, y = -1 and z = -2.

7x+5=6x I don’t get this because I have no idea what to subtract by, and I know the answer is -5 but I have no idea how to get there
Answers
Answer:
Step-by-step explanation:
7x + 5 = 6x Subtract 6x from both sides
7x - 6x +5 = 6x -6x
x + 5 = 0 Subtract 5 to both sides
x + 5 - 5 = 0 - 5
x = -5
7x + 5 = 6x
Given the numbers, our first step will be to subtract 7 from both sides:
7x - 7x = 0
6x - 7x = -x
Now our equation is:
5 = -x
Since -x is the variable, we divide everything by it (note that x alone is always equal to 1):
5 / -1 = -5
-1 / -1 = 1
Our final answer is -5/1. This improper fraction reduces to -5.
By subtracting 6 from both sides, the same answer would be received.

The value of the angle of the quadrilateral is 80° .
A quadrilateral in geometry is represented as a four-sided polygon with four corners (vertices) and four sides .
The Latin words quadri, a variation of four, and latus, meaning "side," are the source of the name. In reference to other polygons, it is also known as a tetragon, from the Greek "tetra" for "four" and "gon" for "corner" or "angle" (e.g. pentagon). Since "gon" is an anagram for "angle," it is also known as a quadrangle or 4-angle.There are two types of quadrilaterals: simple (not self-intersecting) and complex (self-intersecting, or crossed). Convex or concave quadrilaterals are simple quadrilaterals.The sum of all the angle measures of a quadrilateral is 360°Given angles of the quadrilateral are 110° ,90⁰ and 80⁰.
Now let us consider the fourth angle be x.
∴110°+ 90⁰ + 80⁰ + x = 360°
or, x = 360° - (280°)
or, x = 80°.
The missing angle of the quadrilateral is 80°

Answer: Julie is 8 years old. Ann is 12 years old.
Step-by-step explanation:
A=Ann's age. J=Julie's age
A=J+4
A-4=(J-4)*2
A-4=2(J-4)
A=2(J-4)+4
2(J-4)+4=J+4
2J-8+4=J+4
2J-4=J+4
2J=J+8
J=8
A=J+4
A=8+4
A=12
Julie is 8 years old. Ann is 12 years old.
Julie's present age (x) is 8 years old, and Ann's present age (x + 4) is 12 years old. Julie is 8 years old and Ann is 12 years old.
Let's denote Julie's age as x.
Since Ann is 4 years older than Julie, her age can be represented as x + 4.
Four years ago, Julie's age was x - 4 and Ann's age was (x + 4) - 4 = x.
Since Ann was twice as old as Julie, we can write the equation
: x = 2(x - 4).
Simplifying the equation, we get: x = 2x - 8.
Rearranging the terms, we find: x - 2x = -8.
Combining like terms, we have: -x = -8.
Finally, solving for x, we get: x = 8.
Therefore, Julie's present age (x) is 8 years old, and Ann's present age (x + 4) is 12 years old.
