Graph the linear equation y=2/3x-5
Answer:
As the given equation is a linear equation, to graph it, we simply need to calculate two points on the line, plot these points, then draw a straight line through them.
Given equation:
[tex]y=\dfrac{2}{3}x-5[/tex]
Calculating two points on the line:
[tex]\textsf{when }\: x=0 \implies \dfrac{2}{3}(0)-5=-5 \implies (0,-5)[/tex]
[tex]\textsf{when }\: x=6 \implies \dfrac{2}{3}(6)-5=-1 \implies (6,-1)[/tex]
Plot these points and draw a straight line through them (attached).

What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Mr. Ellis has started a vegetable garden.
He bought 15 bags of soil and 3 bags of fertilizer for 282.72.
He realized he did not have enough supplies so he bought another 5 bags of soil and 2 bags of fertilizer for 107.23.
Let the cost of each bag of soil be x and the cost of a bag of fertilizer be y.
Then we have the linear equations,
15x + 3y = 282.72
5x + 2y = 107.23
On solving the equations 1 and 2, we have
x = 16.25 and y = 12.99
The cost of each bag of soil is $ 16.25 and the cost of each bag of fertilizer is $ 12.99.

jamal is attending a university where fitr tuition one year costs 11,800. he has a scholarship worth 1,500 per year he earns 2,500 per year at his part time job. he plans to take out a loan to cover the remaining tuition costs. Tuition will increase by 100 each year. If he completes collage in 4 years , how much money will jamal need to borrow
Answer:
Jamal will have to borrow 31,800.
Step-by-step explanation:
Total tuition for the full four years = 11,800 + 11,900 + 12,000 + 12,100 = 47,800
Total money from scholarship = 1,500 × 4 = 6,000
Total income received = 2,500 × 4 = 10,000
Total money to borrow = 47,800 - 6,000 - 10,000 = 31,800

The terms that can be used to best describe the relationship between 60 degree angle and the angle labelled y degree is:
Vertically opposite angles.Equal angles.Angles equating to 60 degree.Since vertically opposite angles are equal, y° = 60°.
[tex]\rule[225]{225}{2}[/tex]
Answer:
Vertical angles
Step-by-step explanation:
The 60° angle and the angle marked y° are vertical angles. Vertical angles are equal. They are formed by two lines crossing (intersecting lines) I like to think of them like a pair of scissors, opening and closing! The angles get bigger or smaller together. The angle marked x° and the unmarked angle are another pair of vertical angles.

What is an Equilateral Triangle?An equilateral triangle has three sides that have the same length. The triangle is defined as the plane two-dimensional figure with three sides having the sum of the three angles of 180 degrees.
Since the figure is missing in the question so I have attached the figure of the points on the graph for better understanding.
The given coordinates are as follows:-
a (-3, 2)
b (-6, -2)
c (0, -2)
Use the distance formula,[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] , to find ab.
ab = √[(−6−(−3))² + (−2−2)²]
ab = √25
ab = 5 units
Therefore the distance between A and B is 5 units.

How to determine the true solution?The equation is given as:
x^2 + 7x + 12 = 12
The first step in solving the equation is to equate the equation to 0.
i.e.
x^2 + 7x + 12 - 12 = 0

Percy is not correct because he applied the zero product property to a factored expression that was not equal to 0. He should have subtracted 12 from both sides to get x2 + 7x = 0 before factoring. The correct solutions are 0 and -7.
find the value of x PLS HELP I WILL GIVE BRAINLIEST if its right :D
Answer:
x=21
Step-by-step explanation:
For simplicity's sake, I started by naming the angles. Please reference the attachment.
For this, we're using parallel lines with one intersecting line (transversal) to give us valuable information about the angles.
First, based on the Corresponding Angles Theorem, corresponding angles, such as A and B, are congruent.
This means that angle B can also be represented by the expression 6x-19.
Furthermore, since angles B and C are on the same line, they must be supplementary, meaning that they add up to 180 degrees.
This said, we can set up an equation to solve for x because B+C=180
6x-19+3x+10=180
Combine Variables
9x+10-19=180
9x-9=180
Add 9 to both sides to isolate x
9x=189
Divide both sides by 9
x=21
This problem could have also been solved with various other theorems such as, but not limited to:
Keep in mind a prerequisite for all of these theorems except the vertical angles theorem are that it must be for a transversal cutting/intersecting 2 parallel lines.
The Alternate Exterior Angles Theorem states that alternate exterior angles are congruent (A and D)
The Alternate Interior Angles Theorem states that alternate interior angles are congruent (C and E)
The Vertical Angles Theorem states the vertical angles- angles across from each other- are congruent (B and D)
The Same Side Exterior Angle Theorem states that same side exterior angles supplementary (A and F)
The Same Side Interior Angle Theorem states that same side interior angles are supplementary (E and B)

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. David invested $230 in a savings account that offers a 3% return on the investment. The value of David's investment will be at least $415 after a period of years. Hint: Use the formula A = P(1 + r)t, where A is the amount after t years, P is the amount invested, r is the rate of interest, and t is the time period. Use a calculator to compute the answer, and round it off to the nearest year.
The value of David's investment will be at least $415 after a period of 20 years
Compound interestThe formula for calculating the compound interest is expressed as:
A = p(1+r)^t
Given the following parameters
A = $415P = $230r = 3% = 0.03Substitute
415 = 230(1+0.03)^t
415/230 = 1.03^t

Hello!
First we should figure out what 7 x 800 is.
7x800 is 5,600.
Next, start step 1.
7 x 8 is already 56, so you would multiply 1 in the box
(7x8x1)
Second, step 2.
56 x 100 is 5,600, so you would put 100 in the box.
(56x100)
Finally, step 3.
Put your total in the box
(TOTAL: 5,600)

~~~PicklePoppers~~~Using the quadratic regression model, which is the best estimate of the profit when 350 pounds of food are produced? $5,150 $5,300 $10,150 $11,000
The best estimate of the profit when 350 pounds of food are produced is $5300
How to determine the best estimate?The quadratic regression is given as:
[tex]f(x) = -0.0817x^2 + 102.24x - 20421[/tex]
When 350 pounds are produced, it means that:
x = 350.
So, we have:
f(350) = -0.0817(350)^2 + 102.24(350) - 20421
Evaluate
f(350) = 5354.75
Approximate
f(350) = 5300
Hence, the best estimate is $5300
