Write an equation of the line with a slope of -2/7 and a y-intercept of 5
Y=_____
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.

B(6, 1). Find the equation of the line that contains the given segment.
The line segment is AB.
The equation is y =
Answer:
The equation is:
[tex]y = -x + 7[/tex]
Step-by-step explanation:
Given the endpoints of a side of a rectangle
A(1, 6)B(6, 1)Finding the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:6\right),\:\left(x_2,\:y_2\right)=\left(6,\:1\right)[/tex]
[tex]m=\frac{1-6}{6-1}[/tex]
[tex]m=-1[/tex]
Using the point-slope form of a line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -1 and the point (1, 6)
[tex]y - 6 = -1 (x - 1)[/tex]
[tex]y - 6 = -x + 1[/tex]
[tex]y = -x + 1 + 6[/tex]
[tex]y = -x + 7[/tex]
Thus, the equation is:

what is the range shown in this table
Answer:
14
Step-by-step explanation:
Range is, basically, the span of all y-values.
To find range, you take the highest y-value and subtract from it the lowest y-value.
Here the highest "y" is 7 and the lowest is -7, so the range is 14.

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.

Part a: The value of x such that the both lines are parallel to each other is (x = 12).
Part : The value of y such that the both lines are parallel to each other is (y = 108).
What is defined as the corresponding angles?Corresponding angles are generated when two parallel lines have been intersected by a transversal. The definition of corresponding angles states that when two parallel lines intersect with a third, the angles that take up the same relative position at every intersection are said to be corresponding angles to one another.In the given figure;
Part a: For making the lines w and t parallel to each other; their corresponding angles must be equal.
Thus,
4x + 60 = 9x
Solving;
9x - 4x = 60
5x = 60
x = 12
Thus, the value of x for which both lines w and t are parallel is 12.
Part b: For making the lines u and v parallel to each other; their corresponding angles must be equal.
Thus, 9x = y
Put x = 12.
y = 9×12
y = 108.
Thus, the value of y for which both lines u and v are parallel is 108.

Using the given table of an exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Type your answers in as numbers. Example: Growth Factor: 3.5, Rate of Increase: 2.5. (Do not input your rate of increase as a percent.)
Answer:
Growth rate is -0.25
Growth factor is 0.75
Step-by-step explanation:
The general form of an exponential equation is;
y = a(1 + r)^x
Where a is the initial value
r is the growth rate
For x = 3; we have
168.75 = 400(1 + r)^3 •••• (i)
For x = 2, we have
225 = 400(1 + r)^2 •••••(ii)
Divide i by ii
That will be;
168.75/225 = 1 + r
1 + r = 0.75
r = 0.75-1
r = -0.25
The growth rate is -0.25
The growth factor is 1-0.25 = 0.75

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

Find the value of “X”
Answer:
x = 27
Step-by-step explanation:
(3x - 17) + (x + 40) + (2x - 5) = 180
6x = 17 - 40 + 5 + 180
6x = 162
x = 27
Answer:
The value of x is 27°.
Step-by-step explanation:
Given that total angles inna triangle is 180°. In order to find the value of x, you have to add up all the expressiobs to form 180° :
(3x - 17)° + (x + 40)° + (2x - 5)° = 180°
6x + 18° = 180°
6x = 180° - 18°
6x = 162°
x = 162° ÷ 2
x = 27°
4x+8=7.2+5x
solve for x
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
