The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

Answer:
So first y intercept
SO the first part where the line hits the Y axis is 2
So the y intercept is 2 Which leaves 2 choices .
Now from that y-intercept or from any point, find the slope by just rising or running till you reach a point which in this case would be

Suppose Anthony Ianni attempted 18 baskets in a basketball game. If the ratio of baskets made to baskets missed is 1:5, how many baskets did Ianni make?
Answers
Answer:
Number of baskets Lanni make = 3 basket
Step-by-step explanation:
Given:
Total attempt = 18 times
Ratio(Basket make : Basket missed) = 1:5
Find:
Number of baskets Lanni make
Computation:
Number of baskets Lanni make = Total attempt x [Basket make ratio]
Number of baskets Lanni make = 18 x [1/(1+5)]
Number of baskets Lanni make = 3 basket

What is the 10th term in -9,-6,-1,6,15
Answers
Answer:
90
Step-by-step explanation:
This is an increasing sequence, with -9 as its first term. The first increase is +3, then +5, +7, and +9. The differences increase by 2 each time. The sixth term will be 15 + 11, and the seventh would be 15 + 11 + 13. We can follow this pattern to get to the tenth term. 15 + 11 + 13 + 15 + 17 + 19 = 90

Answers
Answer:
See below.
Step-by-step explanation:
All statements of congruent angles and congruent segments are correct.
A similarity statement can be written ...
Write a similarity statement ...
ABCD ~ HJKL
The reason written in the problem is incorrect. The polygons are similar, not congruent, so you cannot state that they are congruent as a reason for them to be similar.
This is the correct reason:
"The reason as why the two shapes are similar is that each angle A, B, C, D is congruent to each corresponding angle H, J, K, L, respectively, and the lengths of corresponding sides are proportional."
"A similarity ratio is a ratio that compares the lengths of the corresponding sides of two similar polygons. The ratio is written in the same order as the two
polygons."
For the similarity ratio, we use two corresponding sides.
AB = 8; HJ = 12
AB/HJ = 8/12 = 2/3
The similarity ratio of ABCD to HJKL is 2/3.

A test is worth 60 points. Multiple-choice questions are worth 2 points, and
short-answer questions are worth 5 points. If the test has 15 questions, how
many multiple-choice questions are there?
O A. The number of multiple-choice questions minus the number of
short-answer questions is 60.
OB. The number of multiple-choice questions times the number of
short-answer questions is 15.
C. The number of multiple-choice questions plus the number of
short-answer questions is 15.
D. The number of multiple-choice questions plus the number of
short-answer questions is 60
Answers
Answer:
C. The number of multiple-choice questions plus the number of
short-answer questions is 15.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of multiple-choice questions
y is the number of short-answer questions.
Multiple-choice questions are worth 2 points, and short-answer questions are worth 5 points.
This means that:
[tex]2x + 5y = 60[/tex]
The test has 15 questions.
This means that:
[tex]x + y = 15[/tex].
Which means that option C is the correct answer.
Answer:
C. The number of multiple-choice questions plus the number of short-answer questions is 15.
Step-by-step explanation:
x + y = 15

1. Anakin is saving for a Xbox One. He currently has $165 saved and earns $40 per week doing chores around the house. If an Xbox costs $500 plus 10% sales tax, how long will it take for him to save that amount? Write your answer in a complete sentence.
2. Write an equation in slope-intercept form for the previous scenario. Define the domain and range for Anakin. Graph the equation on the coordinate plane. Circle the point at which he has saved enough to purchase the Xbox.
3. For the following system of equations, complete a table of at least 5 points for each equation, then graph the system on the coordinate plane. Describe the solution. y = -3x + 4 6x + 2y - 8 = 0
4. Solve the following system of equations: y - 3x + 15 = 10 6 - 4x = y
5. Create and solve a system of equations for the following scenario: Luke and Leia are selling hot dogs and hamburgers at a minor league baseball game. At the end of the day they determine they have sold a total of 45 items and earned $195. If hot dogs cost $4 and hamburgers cost $5, how many did they sell of each?
6. Graph the following system of linear inequalities. Identify at least two points in the solution: y < 5 - 2x x + 5y > -7
Answers
Step-by-step explanation:
The price of Xbox one = $500
Sales tax = 10%
The total cost of Xbox one = 500 + (10% × 500 )
= 500 + (0.010 × 500)
= 500 + 50
= $550
Anakin currently has = $165
He earns per week = $40
Let the time (in weeks) will take for him to save the amount be t
165 + (40t) = 550
40t = 550 - 165
40t = 385
t =
t = 9.625 ≈ 10 weeks
It will take 10 weeks to save the amount.

The length of a photograph of Mr. Lemley playing golf is 1475 inches. If the area
of the photo is 33/20 square inches, what is the width of the photograph? *
Answers
Answer:
1.12 × 10^-3
Step-by-step explanation:
The computation of the width of the photograph is as follows:
As we know that
Area of the rectangle = length × width
33 ÷ 20 square inches = 1475 inches × width
So, the width is
= Length ÷ area
= 1475 inches ÷ (33 ÷ 20 square inches)
= 1.12 × 10^-3

(B) 48 feet
(C) 177 feet
(D) 707 feet
Answers
Answer:
47 feet
Step-by-step explanation:
Shawn is placing a fence around a circular garden with diameter of 15 foot
π = 3.14
Therefore the circumference can he calculated as follows
= π × diameter
= 3.14 × 15
= 47.1 feet
Hence the circumference to the beatesr tenth is 47 feet
