The graph of which equation passes through the point
(4, - 3) and has a slope 4
A.5x+4y=8
B.5x - 4y = 8
C.4x + 5y = 8
D.4x - 5y = 8
The equation that passes through the point (4, -3) and has a slope of 4 is option A: 5x + 4y = 8.
To determine which equation passes through the point (4, -3) and has a slope of 4, we can substitute the values of x and y into each equation and check if the resulting equation is true.
Let's substitute x = 4 and y = -3 into each equation:
A. 5x + 4y = 8
Substituting x = 4 and y = -3:
5(4) + 4(-3) = 20 - 12 = 8
The equation is true for points (4, -3).
B. 5x - 4y = 8
Substituting x = 4 and y = -3:
5(4) - 4(-3) = 20 + 12 = 32
The equation is not true for points (4, -3).
C. 4x + 5y = 8
Substituting x = 4 and y = -3:
4(4) + 5(-3) = 16 - 15 = 1
The equation is not true for points (4, -3).
D. 4x - 5y = 8
Substituting x = 4 and y = -3:
4(4) - 5(-3) = 16 + 15 = 31
The equation is not true for points (4, -3).
Therefore, the equation that passes through the point (4, -3) and has a slope of 4 is option A: 5x + 4y = 8.

Plot and connect the points A(4, 6), B(4, 0), C(1, -3), and D(1, 3), and find the area of the parallelogram formed.
Answer:
18 square units
Step-by-step explanation:
The parallelogram has been plotted in the attached figure
The area of a parallelogram is b x h
where b is one side and h is the vertical distance between the two bases
In the figure, we see that base = AB is parallel to the y-axis
This means the y-coordinates of A and B are the same and the distance is obtained by taking the absolute difference between the x-coordinates of A and B
b = |x1 - 2| = |6 - 0| = 6
The height h is a perpendicular line from point D(1, 3) to the base which touches the base at point E
Since this line is horizontal to the x-axis in the figure, the y coordinates of the endpoints of the line are the same i.e y1 =3 and y2 = 3
Therefore h = absolute difference between the x coordinates
= |1-4| = 3
Given b = 6, h = 3
area = 6x 3 = 18 square units

What are the coordinates of S? the image is below
The coordinates of point S are (4, 3.5)
How to find the coordinates of point S?Remember that the coordinates of a point are written in the notation (x, y), such that the first value is the value in the horizontal axis, and the second value is the value in the vertical axis.
Each one of the squares is one unit, then the x-value of the point S is:
x = 4
And for the y-value we can see that the point is halfway between the third and the fourt lines, then:
y = 3.5
Thus, the coordinates of point S are (4, 3.5)

The number of jerseys that the senior class at Legion Academy can purchase for $430, using quadratic equation, is 190.
What is quadratic equation?Quadratic equation is an algebraic equation of the second degree in x, represented in the form of ax²+bx+c=0.
In the quadratic equation, a, b, and c are known values but a ≠ 0 and x is unknown.
Quadratic Equation Formula:x = [-b ± √b² - 4ac]/2a
when ax^2 + bx + c = 0
Equation Model:C = 0 .1x² + 2.4x + 25, where C is the amount, it costs to buy x jerseys.
Simplifying the equation, we get:
x = 0.2 − 2.4 ± 40.4
The two possible values of x are:
1) x = 0.2 − 2.4 + 40.4 = 190
or
2) x = 0.2 − 2.4 − 40.4 = −214

17 The equation 3x + 4 = 16 is modeled below:
The probability that the spinner on the left will land on a 6 and the spinner on the right will land on a shaded area will be 1/9. The correct option is A.
Probability is a branch of mathematics that deals with the measurement and analysis of uncertainty. In other words, probability is the measure of the likelihood or chance that a particular event will occur.
The probability that the spinner on the left will land on a 6 is calculated as,
P₁ = 2 / 12
The spinner on the right will land in a shaded area is,
P₂ = 8 / 12
The total probability will be,
P = ( 2 / 12 ) x ( 8 / 12 )

the ratio of 2/3 to 8 as a fraction in simplest form
To write the ratio of 2/3 to 8 as a fraction in simplest form, we need to divide the numerator and denominator by their greatest common factor (GCF).The GCF of 2 and 8 is 2.So, we divide both the numerator and denominator by 2:2/3 ÷ 8/1 = (2/3) ÷ (8/1) = 2/3 x 1/8 = (2 x 1) / (3 x 8) = 2/24Now, we can simplify the fraction by dividing the numerator and denominator by their greatest common factor again.The GCF of 2 and 24 is 2.So, we divide both the numerator and denominator by 2:2/24 ÷ 2/2 = (2/24) ÷ (2/2) = 2/24 x 1/2 = (2 x 1) / (24 x 2) = 1/12Therefore, the ratio of 2/3 to 8 as a fraction in simplest form is 1/12.
Answer:
How to find Ratio?
Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B. For example, if A is five and B is 10, your ratio will be 5/10
In order to find the ratio of a certain number to another number or the relation of each other, we also need to know the concept of fraction and percentage.

The total angle measurement of a triangle sum above is 180°. So yes, it is possible to only make a right angle triangle but impossible to draw a triangle
What is the triangle?To check if a triangle can be drawn with 25°, 65°, and 90° angles, we use the Triangle Angle Sum Theorem stating that all triangle angles add up to 180 degrees.
If you add all the angles together (25 + 65 + 90 = 180°), We can draw a triangle based on this sum, but we only consider the angles' nature. The triangle has angles of 25°, 65°, and 90°, making it a right triangle. It only applies to right triangle and not others triangle .

Which measure of center is best to describe salaries at the company? Select the statement that BEST explains your choice.
a. the mean, because people who earn too little make the median too small
b. the mean, because most workers earn a salary that is near this value
c. the median, because it is the measure of center with the lower value
d. The median, because people who earn a lot make the mean too large
The best measure of center to describe salaries at the company is the median. The Option D is correct.
Why is median best measure to describe salaries?The reason is that the median is less affected by extreme values or outliers which can greatly affect the mean. In this case, the mean annual salary is $62,000 while the median is only $35,000.
This large difference suggests that there are some very high earners at the company that are pulling up the mean. The median indicates that half of the employees earn less than $35,000 and half earn more which gives a more accurate picture of the typical salary at the company.
