Write an equation in slope-intercept form for the line.
(-7,2) and (5,8)
The equation in slope-intercept form for the line that passes from the points (-7,2) and (5,8) is y = (1/2)x -3/2.
We know that, the slope intercept form is given by:-
y = mx + b
Where,
(x,y) is the ordered pair of every point on the line
m is the slope of the line
b is the y-intercept of the line
We know that, slope = (8-2)/(5-(-7)) = 6/12 = 1/2
Putting (-7,2) in (x,y) and m = 1/2 in the slope intercept form, we get,
2 = (1/2)(-7) + b
2 = -7/2 + b
b = -3/2
Hence, the slope intercept form of the line is y = (1/2)x -3/2.

What is the difference between the sum of the measures of the interior angles in an octagon and the sum of the measures of the interior angles in a hexagon?.
The difference between the sum of the measures of the interior angles in an octagon and the sum of the measures of the interior angles in a hexagon is 360°.
Interior angle refers to the angle inside a polygon that is formed by two of its adjacent sides. The sum of the measures of the interior angles of a polygon is given by the equation:
180°(n - 2)
where n is the number of sides
An octagon is a polygon that has 8 vertices and 8 sides. The sum of the measures of the interior angles of an octagon is:
180°(8 - 2) = 180°(6) = 1080°
On the other hand, a hexagon is a polygon that has 6 vertices and 6 sides. The sum of the measures of the interior angles of an octagon is:
180°(6 - 2) = 180°(4) = 720°
Subtracting the sum of the interior angles of the two polygons,
1080° - 720° = 360°

When 32 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution.
The negative solution of the given statement is - 4.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Let the unknown number be 'n'.
∴ When 32 is subtracted from the square of a number, is n² - 32 and the result is 4 times the number which is equal to 4n,
So, n² - 32 = 4n.
n² - 4n - 32 = 0.
n² - 8n + 4n - 32 = 0.
n(n - 8) + 4(n - 9) = 0.
(n - 8)(n + 4) = 0.
n - 8 = 0 Or n + 4 = 0.
n = 8 Or n = - 4.

How do I find angle x?
By using the fact that the internal angles of a triangle always add up to 180°, we will see that x = 100°.
How to find the angle x?Remember that the sum of all the internal angles of a triangle is always equal to 180°.
On the image we can see two triangles, let's define the angle at the right as A. and the angle at the left as B
We can write:
A + B + x = 180°
And for the inner triangle the angles give:
A/2 + B/2 + 140° = 180°
So we have a little system of equations:
A + B + x = 180°
A/2 + B/2 + 140° = 180°
If we multiply the second equation by 2 we get:
A + B + 280° = 360°
With the first equation we can write:
A + B = 180° - x
And replace that in the above equation
(A + B) + 280° = 360°
180° - x + 280° = 360°
Now we can solve this to get the value of x:
180° + 280° - 360° = x = 100°
We conclude that the measure of angle x is 100°

Solve for x. It's telling me right but all have to ask is to just please answer quick
Answer: (7y+237) / 8 = x
Step-by-step explanation:
So your equation is:
(2y+50) + (7x-248) + (5y-17) + (x+44)
First thing to do is combine all the like terms. Lets start with y. So that would be 2y + 5y= 7y and 50 + -17 is 33. The new equation is:
(7y + 33) + (7x-248) + (x+44)
Now we will combine the x. We will do -248+44= -204
and 7x+x= 8x.
Now our new equation is:
(7y + 33) + (8x+-204)
Now we can subtract 33 from -204. That is 237.
Now we have 7y+237 = 8x
To isolate x we need to divide by 8. That will give us this:
(7y+237) / 8 = x

For the parallelogram NELR, we get the value of x as 7°.
We are given a parallelogram NELR.
We know that , the adjacent angles of a parallelogram are supplementary.
So, we get that:
∠ N + ∠ E = 180°
Substituting the values, we get that:
7 x + 33 + 11 x + 21 = 180
18 x + 54 = 180
18 x = 180 - 54
18 x = 126
x = 126 / 18
x = 7°

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant of variation, rate of change, and constant ratio.
Solving for the value of constant of variation
When a quantity varies directly with others, then we have a relation, y = kx, where k is the constant of the proportion —-- 1
Given the relation is y = 5x —-- 2
On comparing both the equation 1 and 2, we have,

Describe the transformation of the parent function f(x) . h(x)=0.25 f(x)
The transformation applied to the parent function is vertical compression by a factor of 0.25.
In mathematics, functions can be manipulated algebraically to obtain graphs of functions through certain transformations. Such transformations are reflections of the x-axis or the y-axis. To flip a function f(x) on the x-axis, multiply the whole function by a negative value to get -f(x), and to flip a function f(x) on the y axis, f(-x ), specify the x variable with a negative value.
Vertical compression helps shrink features vertically. Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values are affected.
It is vertically compressed by a factor of 0.25.

Explanation:
The figure of the triangle is shown below.
If we are finding image of the triangle about X-axis all the x -co-ordinates will remain same, but y co-ordinate will change it's sign.
So, co ordinate of A' = (1, -4)

That is,
(s circle t) (negative 7) : This is a notation for compound function.
A function that takes another function as an argument is referred to as a compound function.
s(t(-7)) is the alternative notation for this compound function, which means that the value obtained from the function t(-7) will be used in the function s. (x).
Now, let's calculate the value of t(-7):
That is,
t(x) = 3x
t(-7) = 3 × (-7) = -21
Next, apply the value of t(-7) for s(x)
That is,
