The clue to find 'x' is-
As both, the lines here are intersecting at a point to form VERTICALLY OPPOSITE ANGLES.According to this theory (2x+20)=60
So, (2x+20)=60
= 2x=60-20
= 2x= 40
= x=40/2
= x=20 degrees
that angle is equal to the 60 degree angle. that means that angle also equals 60 degrees. 2(20) is 40 and 40 + 20 is 60

2x − 3y = -5 y = 2 + x The value of x in the system of equations is: x = -1. x = -3. x = 1. x = 3.
Answers
Answer: We can solve this system of equations by substituting the expression for y in terms of x from the second equation into the first equation, and then solving for x.
First, we substitute y = 2 + x from the second equation into the first equation, giving:
2x - 3(2 + x) = -5
Simplifying this expression by distributing the -3, we get:
2x - 6 - 3x = -5
Combining like terms, we get:
-x - 6 = -5
Adding 6 to both sides, we get:
-x = 1
Multiplying both sides by -1, we get:
x = -1
Therefore, the value of x in the system of equations is -1.

What is the gradient of the blue line?

Answers
Answer:
1/4
Step-by-step explanation:
Using points (0 ; 1) and (4 ; 2)
m= y2-y1 / x2-x1
= 2-1 /4-0
= 1/4
The gradient of the blue line is, 1/4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the blue line are (3, -3) and (3, -6).
Now,
Since, The equation of line passes through the points (4, 2) and (8, 3).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 2) / (8 - 4)
m = 1 / 4
m = 1/4
Thus, The gradient of the blue line is, 1/4

The graph of this line shows the total amount Katrina earns for working a corresponding number of hours. How much did Katrina earn for working 7 hours?
Answers
The correct statement is that for each hour, the earnings go up by $7. Option A
What is straight line graph?If we have the equation of the line, we can substitute the value of 7 for the number of hours into the equation and solve for the earnings. The equation would typically be in the form of "earnings = slope * hours + y-intercept," where the slope represents the rate of earnings per hour and the y-intercept represents the earnings when no hours are worked.
We can find the slope of the graph to know as said above;
m = y2 - y1/x2 - x1
m = 14 - 0/2 - 0

Answers
Angles at the center of a circle add up to 360 degrees.
The measure of angle GEH in the circle is (d) 116 degrees
The given parameters are:
\(\mathbf{\angle FEG = 64^o}\)
Since line FH is the diameter of the circle;
It means that:
\(\mathbf{\angle FEG + \angle GEH = 180^o}\) --- By angle on a straight line theorem
Substitute 64 for FEG
\(\mathbf{64 + \angle GEH = 180^o}\)
Subtract 64 from both sides
\(\mathbf{\angle GEH = 180^o - 64}\)
Evaluate like terms
\(\mathbf{\angle GEH = 116^o}\)
Hence, the measure of angle GEH in the circle is (d) 116 degrees

Answers
Answer:
a) \(y=1\)
b) \(x=-3\)
Step-by-step explanation:
Recall the forms of vertical and horizontal lines
Horizontal lines come in the form of \(y=0x+b\), so the slope of the equation is zero. The value of b will be the y-value of the point that you're given.
This means that the equation for a would be y=1
Vertical lines come in the form of \(x=a\). For this line, the value of a would be equivalent to the x-value of the given point. Therefore, b. would be \(x=-3\)

In a data distribution that is skewed left.
Answers
The median will be greater than the mean in a left-skewed distribution
We have,
In statistics, skewness is a measure of the asymmetry of a probability distribution around its mean.
A distribution is said to be skewed left if it has a long tail on the left side and the bulk of the data is on the right side.
When the data is skewed left, it means that the distribution is being pulled towards the left side.
This is because there are a few extreme values on the left side that are pulling the mean in that direction.
In contrast, the median is the middle value of the dataset, and it is not influenced by outliers.
For a left-skewed distribution,
The median will be greater than the mean because the mean is being pulled towards the left by the few extreme values.
In a data distribution that is skewed left, the mean will be less than the median.
This is because the mean is sensitive to outliers and is pulled towards the direction of the skewness, while the median is not affected by extreme values and is a more robust measure of central tendency.
Therefore,
The median will be greater than the mean in a left-skewed distribution

The expression that could be used to calculate the amount Trina was charged in interest for the billing cycle is (APR / 365) x 30 days x adjusted balance.
What is the adjusted balance method?The adjusted balance method is one of the methods for computing the finance charge (interest and other fees) for credit cards.
The adjusted balance is the ending balance determined after adjusting the opening balance with purchases and payments.
Credit card interest method = adjusted balance method
Beginning balance = $780
Purchase = $170
Payment = $210
Adjusted balance, AB = $740 ($780 + $170 - $210)
APR = 17% = 0.17 (17/100)

\(x = \frac{9}{ \sin(38°) } ≈30.37\)

The union of sets A and B is {1, 2, 3, 4, 5, 6, 7, 8}.
The union of two sets A and B is the set of all elements that are in A, or B, or both. In this case, the elements in set A are {1, 2, 3, 4, 5} and the elements in set B are {5, 6, 7, 8}.
To find the union of these sets, we simply combine all the elements from both sets but remove any duplicates.
Therefore, the answer that shows the union of sets A and B is {1, 2, 3, 4, 5, 6, 7, 8}, since it contains all the elements from both sets without any duplicates.

Purple is worth 2 points and yellow is worth three points. Pick 9 candies from the bag
Create a system of equations where the combination of the candies gives you a total of 22 points. Make sure you label and define your variables.
Answers
The system of equations where the combination of the candies gives you a total of 22 points are:
x + y = 9
2x + 3y = 22
How can we create system of equations?To create the equations, we shall first define the variables:
x = the number of purple candies
y = the number of yellow candies
Next, we shall use the given information that purple candies are worth 2 points and yellow candies are worth 3 points.
Then, we would make sure that the total number of candies selected is 9.
The first equation represents the total number of candies selected:
x + y = 9
The second equation represents the total number of points obtained:
2x + 3y = 22
Therefore, the system of equations is:
x + y = 9
2x + 3y = 22
This is a system of linear equations.
