Answer:
X = 13/2
Step-by-step explanation:
7(x-2)=3(x+4)
Distribute
7x - 14 = 3x + 12
-3x from both sides
4x -14 = 12
Add 14
4x = 26
Dive by 4
X = 13/2

Answer:
[tex]\displaystyle 31[/tex]
Step-by-step explanation:
Angles Y and X form a linear pair, therefore you use the Linear Pair Theorem to solve for x:
[tex]\displaystyle 180° = [2s - 4]° + [s + 91]° → 180° = [87 + 3s]° → 93 = 3s; 31 = s[/tex]

What percent of the large square is shaded?
Answer:
48%
Step-by-step explanation:
a little less than half is shaded
The percent of the shaded square will be 48%.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
A large square is shown in figure.
Now,
In a figure,
The number of small squares = 100
And, Number of shaded squares = 48
Hence, The percent of shaded square = 48/100 × 100
= 48%

PLS HELP. Find the value of each variable.
6. x=100
7.x=75
8.x=30
10.x=112
11.x=58 y=58
Answer:
6) x = 70°
7) x = 75°
8) x = 30°
10) x = 112°
11) x = 58° , y = 58°
Step-by-step explanation:
6) two congruent sides means two congruent angles
x + x + 40 = 180 2x = 140
7) two congruent sides means two congruent angles
both base angles measure 75 degrees
8) isosceles triangle (has two equal sides) 75(2) + x = 180 150 + x = 180
10) two congruent angles means two congruent sides
44 + 2n = 180 2n = 136 n = 68
angles n and x form a linear pair and equal 180
180 - 68 = 112
11) isosceles triangle so ∡x = ∡y 64 + x + x = 180
64 + 2x = 180 2x = 116 x = 58

Estimate the values of x when y=1
Step-by-step explanation:
if one were to put the y value the equation they could find out what x is for a certain value of y
putting the value of y(1), we get the equation
1=4x-1
2=4x
x=0.5
the value of x when y is 1 is =0.5
NOTE: I got this explanation on brainy on someone else I am not taking the credit
a) The graph of y = 4x - 1 is shown in attached image.
b) By using the graph at y = 1 the value of x is 1/2.
What is Linear expression?A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The function is,
y = 4x - 1
Now, The graph of function y = 4x - 1.
And, At y = 1;
By the graph the value of x = 1/2.
And, In mathematically;
At y = 1
The value of x is;
y = 4x - 1
1 = 4x - 1
4x = 2
x = 2/4
x = 1/2
Thus,
a) The graph of y = 4x - 1 is shown in attached image.
b) By using the graph at y = 1 the value of x is 1/2.

Answer:
Option D
Step-by-step explanation:
From the picture attached,
Coordinates of point C → (1, 3)
Coordinates of point C'→ (-1, -3)
Option A.
rotation 180° counterclockwise about the origin.
Rule for the rotation is,
(x, y) → (-x, -y)
By this rule,
C(1, 3) → C'(-1, -3)
True
Option (B)
Reflection across the origin
Rule for the reflection is,
(x, y) → (-x, -y)
By this rule,
C(1, 3) → C'(-1, -3)
True
Option C
Rotation 180° clockwise about the origin
Rule for the rotation is,
(x, y) → (-x, -y)
By this rule,
C(1, 3) → C'(-1, -3)
True.
Option D
Reflection across the line y = -x
Rule for the reflection,
(x, y) → (-y, -x)
By this rule,
C(1, 3) → C'(-3, -1)
False.
Therefore, Option D will be the answer.

What is the value of x in the equation x - y = 30, when y = 15?
4
8
80
200
Answer:
x = 45
Step-by-step explanation:
1. Replace y with 15
x - 15 = 30
2. Add 15 to both sides
x - 15 + 15 = 30 + 15
3. Combine like terms
x = 45

Pete bought a shirt on sale for $
18
18, which is one-half the original price. What was the original price of the shirt?
Solution:
Step 1. Read the problem. Make sure you understand all the words and ideas. You may need to read the problem two or more times. If there are words you don’t understand, look them up in a dictionary or on the Internet.
In this problem, do you understand what is being discussed? Do you understand every word?
Step 2. Identify what you are looking for. It’s hard to find something if you are not sure what it is! Read the problem again and look for words that tell you what you are looking for!
In this problem, the words “what was the original price of the shirt” tell you what you are looking for: the original price of the shirt.
Step 3. Name what you are looking for. Choose a variable to represent that quantity. You can use any letter for the variable, but it may help to choose one that helps you remember what it represents.
Let
p
=
p= the original price of the shirt
Step 4. Translate into an equation. It may help to first restate the problem in one sentence, with all the important information. Then translate the sentence into an equation.
The top line reads:
Step 5. Solve the equation using good algebra techniques. Even if you know the answer right away, using algebra will better prepare you to solve problems that do not have obvious answers.

p=36, which means the original price was
$36
$36. Does
$36
$36 make sense in the problem? Yes, because
18
18 is one-half of
36
36, and the shirt was on sale at half the original price.Step 7. Answer the question with a complete sentence.
The problem asked “What was the original price of the shirt?” The answer to the question is: “The original price of the shirt was
$36
$36.”

The degree of the polynomial function f(x) is 3.
The roots of the equation f(x) = 0 are - 1,0, and 4
Which graph could be the graph of f(x)?
Answer: Top right corner
This graph shows a curve going through x = -1, x = 0 and x = 4 on the x axis. These are the three roots or x intercepts.
The graph in the bottom right has a root of x = -4, but that's not one of the listed roots in the instructions. So we rule this graph out.
The other two graphs only have two roots, and not three, so we rule them out as well.
Step-by-step explanation:
If the degree of a polynomial function is an odd number, the ends of the graph will go in opposite directions. (one going up and one going down)
The graph must pass the x-axis at the points -1, 0, 4.
Only the top-right graph satisfies our conditions.

Answer:
No
Step-by-step explanation: If right press thanks and rate 5/5 plz
Answer:
Not proportional.
Step-by-step explanation:
To find out if the fractions are proportional, you have to cross multiply each fraction to see if each number multiplied is the same. 2 * 4 = 8 and 1 * 9 = 9. The numbers are not the same here so it is not proportional.
