Answer:
First, if we look at these angles, we can see that they are vertical.
Vertical angles are congruent(meaning they measure the same degrees).
So let's set up an equation where -2x - 6 is equal to 40°, because they are vertical angles.
-2x - 6 = 40°
Solve for x!
Get rid of constants by performing the inverse operation of subtraction which is addition(because 6 is negative).
Make sure to apply this to both sides!!
(Add 6 to both sides)
+6 +6
-2x = 46
Now, we isolate x by getting of x's co-efficient.
To do that, we also perform the inverse operations.
The inverse operation of multiplication is division (since -2 is being multiplied by x).
(Divide -2 from both sides)
÷ -2 ÷ -2
x = -23
Therefore, x measures -23°.
Answer:
x = -23
Step-by-step explanation:
Vertical Angle Theorem
A pair of opposite angles formed by intersecting lines.
Vertical angles are congruent.
⇒ -2x - 6 = 40
Add 6 to both sides:
⇒ -2x = 46
Divide both sides by -2
⇒ x = -23

= 2 + 2(2 × 2)
= 2 + 2(4)
= 2 + 8

The graph of the given linear equation, y = 1/2x + 1 (-x+2y=2), is given in the diagram attached below.
What is the Graph of a Linear Equation?The graph of a linear equation is a straight line graph, and it is represented, in slope-intercept form as, y = mx + b, where m is the slope and b is the y-intercept of the graph.
Given the linear equation, -x+2y=2, rewrite in slope-intercept form:
-x+2y=2
2y = x + 2
y = x/2 + 2/2
y = 1/2x + 1

Convert the following functions.

Write the log form from Part A into the expanded log form. **expression must be fully expanded for
Answers
The logarithmic function is the inverse of the exponential function
The logarithmic equivalent of the exponential function is log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)
How to convert the function?The exponential function is given as:
12^3=x^4 y^3 z^6
Take the logarithm of both sides
log(12^3) =log(x^4 y^3 z^6)
Apply the product rule of logarithm
log(12^3) =log(x^4) + log(y^3) + log(z^6)
Apply the power rule of logarithm
3log(12) = 4log(x) + 3log(y) + 6log(z)
Divide through by 3
log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)
Hence, the logarithmic equivalent of the exponential function is log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)

The area of a rectangle is 45 square inches. One dimension is 5 inches. What is the perimeter
Answers
Answer:
28 inches
Step-by-step explanation:
To begin, the area of a rectangle is base · height. Since we are given one of the sides already, you can make an equation to solve for the other value.
5 · x = 45
5x = 45
x = 9
A rectangle has two pairs of parallel sides, or in easier terms, two sets of sides that are the same. So, the perimeter is going to be two lengths plus two widths.
2 · 5 + 9 · 2 = 10 + 14 = 28

Answer: 1
Step-by-step explanation:
We can start by dividing both sides by 5. This gives us
[tex]6 + s = 7[/tex]
Subtracting 6 from both sides gives us
[tex]s = 7-6=1[/tex]
To check, we can put 1 back in the equation:

[tex]5(7) = 35[/tex]

When the shadow of a flagpole is 36 m long, a 1.8-m fencepost casts a shadow that is 3 m long. How tall is the flagpole?
Answers
Answer:
21.6 m long
Step-by-step explanation:
To do this, we find the scale factor of the fencepost and the shadow.
3/1.8 = 1.66666667
So, we know that when we take the original length and multiply it, we get the new one, so:
1.666666667 * x = 36
x being the original length. Now, we divide both sides by 1.66666667 to get x alone and find the original length.
x = 21.6
To double check, we can take the scale factor and multiply it by the original to get the shadow.
21.6 * 1.666666667 = 36
It is correct

Part 1: Determine the limits of a function given a graph
Answers
The value of limits and function values for a, b, c, d, e, f, g, h, i, and j are 3, -1, does not exist, 3, 1, 2, does not exist, 2 +∞, and -∞ and doesn't follow continuity conditions and its jump continuity.
What is the limit?A limit is a value at which a function approaches the output for the given values in mathematics. Limits are used to determine integrals, derivatives, and continuity in calculus and mathematics.
We have a graph of a function:
For [tex]\lim_{x \to -1^{-1}} f(x)[/tex]
As we can see x approaches -1 and it is a left-hand limit.
[tex]\lim_{x \to -1^{-1}} f(x) = 3[/tex]
For [tex]\lim_{x \to -1^{+1}} f(x)[/tex]
The x approaches the +1 and it is the right-hand limit.
[tex]\lim_{x \to -1^{+1}} f(x) = -1[/tex]
For [tex]\lim_{x \to -1} f(x)[/tex]
Since the left hand and right-hand limits are not the same,
[tex]\lim_{x \to -1^{+1}} f(x)[/tex] = does not exist
From the graph:
f(-1) = 3
Similarly, we can find further values of the limits and functions value:
[tex]\lim_{x \to 2^{-1}} f(x) = 1[/tex]
[tex]\lim_{x \to 2^{+1}} f(x) = 2[/tex]
For [tex]\lim_{x \to 2^{}} f(x)[/tex]
Since the left hand and right-hand limits are not the same,
[tex]\lim_{x \to 2^{}} f(x)[/tex] = does not exist
f(2) = 2
[tex]\lim_{x \to -\infty} f(x) = +\infty[/tex]
[tex]\lim_{x \to +\infty} f(x) = -\infty[/tex]
There are three conditions a graph must follow:
1) function value defined at any given point.
2) left-hand limit and right-hand limit must be equal
3) function value at the point and limit value at the same point must be the same.
In the given function the graph doesn't follow these conditions and its jump continuity.
Thus, the value of limits and function values for a, b, c, d, e, f, g, h, i, and j are 3, -1, does not exist, 3, 1, 2, does not exist, 2 +∞, and -∞ and doesn't follow continuity conditions and its jump continuity.
