Answer:
x = - 3
Step-by-step explanation:
Given
3(x - 6) + 6 = 5x - 6 ← distribute and simplify left side
3x - 18 + 6 = 5x - 6
3x - 12 = 5x - 6 ( subtract 5x from both sides )
- 2x - 12 = - 6 ( add 12 to both sides )
- 2x = 6 ( divide both sides by - 2 )
x = - 3

Answer:
x=3,y= -4
Step-by-step explanation:
ii) x-2y=11
x=11+2y-----(i)
Now,
i) -7x-2y= -13
or, -7(11+2y)-2y= -13
or, -77-14y-2y = -13
or -14y-2y = -13+77
or -16y = 64
or y =64÷(-16)
:: y = -4
Again,
(ii) x-2y= 11
or x-2(-4)= 11
or x+8 = 11
or x = 11-8
:: x = 3

13.5
Explanation:
The equation to find the slope (another word for the rate of change) of the line is (y2-y1)/(x2-x1) when the given points are (x1,y1) and (x2,y2).
When we plug in the given points, (3,-7) and (5,20) we can start solving.
(y2-y1)/(x2-x1)
(20-(-7))/(5-3)
Two negatives make a positive

Step-by-step explanation:
Step 1: Define Equation
6x + 2 = 2(x + 4) - 2
Step 2: Solve for x
Distribute 2: 6x + 2 = 2x + 8 - 2Combine like terms: 6x + 2 = 2x + 6Subtract 2x on both sides: 4x + 2 = 6Subtract 2 on both sides; 4x = 4Divide 4 on both sides: x = 1Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 6(1) + 2 = 2(1 + 4) - 2Multiply: 6 + 2 = 2(1 + 4) - 2Add: 8 = 2(5) - 2Multiply: 8 = 10 - 2Subtract: 8 = 8Here we see that 8 does indeed equal 8.
∴ x = 1 is the solution to the equation.

4x+0.8=5x

0.8 = x
Hope this helps.
Answer:
x = 0.8
Step-by-step explanation:
We are given this equation:
4x+8=7.2+5x
And we want to solve it for x.
To solve equations, we need to isolate the variable (x) on one side, and the numbers on the other side.
First, we can clear the numbers from the right side by subtracting 7.2 from both sides.
4x + 8 = 7.2 + 5x
-7.2 -7.2
_______________
4x + 0.8 = 5x
Now, we can subtract 4x from both sides.
4x + 0.8 = 5x
-4x -4x
_______________
0.8 = x
This can be rewritten to be: x = 0.8
The value of x is 0.8

Write an equation of the line with a slope of -2/7 and a y-intercept of 5
Y=_____
Answers
Answer:
y= -2/7 +5
Step-by-step explanation:
The equation of the line with a slope of -2/7 and a y-intercept of 5 is y=-2/7 x+5.
Given that, slope (m) =-2/7 and y-intercept (c) =5.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The standard form of the slope intercept form is y=mx+c.
Put m=-2/7 and c=5 in y=mx+c, we get
y=-2/7 x+5
Therefore, the equation of the line with a slope of -2/7 and a y-intercept of 5 is y=-2/7 x+5.

Answer:
theres is not table shown
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Solution in y-intercept form y=mx+b
We can calculate the slope of the line using any 2 of the given points: I pick (0,3) and (3,9) . Recall the formula for finding the slope of the line through 2 points (x1,y1) and (x2,y2) as m=(y2-y1)/(x2-x1)
By plugging in the corresponding values, we get (9-3)/(3-0)=6/3=2
Since we now the value of y when x is zero, i.e. the point (0,3) of the table, then the value of b is 3.
Now, putting everything together, we have y=2x+3
Solution in point-slope form y-y1=m(x-x1)
You can proceed the same way above to find the slope m=2
Now use one of the points in the given table to plug into x1 and y1
Doing the last 2 steps will result in y-23=2(x-10) if you use the point (10,23)
Realize that the point slope form of the equation of a line is not unique since using a different point will result in different values of x1 and y1. So the answer is A
6 Find the value of x' and each angle
Answers
The value of x=10 and m∠SOP=50° and m∠ROQ=50° .
When two straight lines intersect each other at a point then vertical angles are formed , there are two pair of vertically opposite angles and also , the vertically opposite angles are equal.
In the given question
m∠SOP = (5x)° ...(i)
and
m∠ROQ = (4x+10)° ...(ii)
and Since the angles m∠SOP and m∠ROQ are vertically opposite , they will be equal .
On equating we get ,
m∠SOP=m∠ROQ
Substituting the values from equation (i) and (ii) we get ,
5x=4x+10
5x-4x=10
x=10.
Substituting the value of x in equation (i) we get ,
m∠SOP = (5*10)° = 50°
Substituting the value of x in equation (ii) we get ,
m∠ROQ = (4*10+10)° = (40+10)° = 50°
Therefore , the value of x=10 and m∠SOP=50° and m∠ROQ=50° .
