Answer:
x = 15
Step-by-step explanation:
The two angles form a straight line so they add to 180
6x-5+6x+5 = 180
Combine like terms
12x= 180
Divide by 12
12x/12 =180/12
x = 15
3,415.72 - 1,838.28 = 1577.44

What is the slope of the line that passes through the points (5, 6)(5,6) and (5, 9) ?(5,9)? Write your answer in simplest form.
Answer:
Step-by-step explanation:
Slope is defined as the "Rise" over the "Run" of a straight line. The Rise is the change in y, and the Run is the change in x. For the given points:
(5,6) and (5,9) the Rise and Run are (going from left to right).
Rise (9-6) = 3
Run = (5-5) = 0
The slope is 3/0, which is undefined (can't divide by zero).

Answer:
47.2°
Step-by-step explanation:
Triangles PRQ and SRQ are congruent by HL. In these right triangles, the acute angles are complementary.
angle PRQ = angle SRQ = 90° -42.8° = 47.2°
The measure of angle PRQ is 47.2°.
“ Use what you know about function notation to complete the statements “ PLS HELPP
Step-by-step explanation:
I don't know the options to pick from.
the 2 main possibilities coming to my mind are
y = f(x)
or
(x, f(x)) or (x, y)
there is no specific function coming to mind. the functional values bounce around above and below the x-axis (positive and negative y-values) with not detectable pattern related to the x values.
the other 2 questions can be found directly in the table :
f(3) means f(x) with x=3, and that is -2
and f(x) = -5 is true, when x = 4

Valery and Manuel ride their bikes 40 miles every Saturday. Valery rides at an average speed of 9.6 miles per hour (mph).
Valery increases her speed by 4% the next time she rides her bike. Her goal is to ride faster than Manuel.
Is the 4% increase enough to ride faster than Manuel? yes or no.
As part of your explanation, identify Valery's new speed. Then explain why or why not she met her goal.
Answer:
9.984, can't tell.
Step-by-step explanation:
9.6 increased by 4% is
9.6 * 1.04 = 9.984 mph.
We don't know from this how fast Manuel rides.
May is going to the grocery store to buy bananas and oranges. The bananas can only be purchased in groups of 65 and the oranges can only be purchased in groups of 5. If May wants to buy the same amount of bananas and oranges, then what is the lowest quantity of bananas that May can buy?
Answer:
65
Step-by-step explanation:
65 is a multiple of 5, so May can purchase 1 group of 65 bananas and 13 groups of 5 oranges to have 65 of each.

Step-by-step explanation:
a and b are two similar solids. the volume of a is 400cm^3
work out the volume of b
Answer:
1350 cm³
Step-by-step explanation:
we have given that,
• Height of A = 10 cm.
1350
• Volume of A = 400cm³.
• Height of B = 15 cm.
• Both A and B solids are similar.
from above told concept we get,
→ V(A) / V(B) = (Height of A)³ / (Height of B)³
Putting all given values we get,
→400/ V(B) = (10)³/(15)³
→400/V(B) = (1000/3375)
→ V(B) = (400*3375) / 1000
→ V(B) = (4 * 3375) / 10
→ V(B) = 1350 cm³. (Ans.)
Hence, Volume of B will be 1350 cm³.
Alejandro has just gotten a new job. The relationship between the number of hours he works, xx, and his total earnings, yy, is represented by the graph below.

Number of Hours
Total Earning (in dollars)
x
y
0
Number of Hours
Total Earning (in dollars)
(4 , 90)
The unit rate is 4 hours per dollar
The unit rate is 22.5 hours per dollar
The unit rate is $90.00 per hour
The unit rate is $22.50 per hour
The statement that is true about the graph as it relates the unit rate is:
d. The unit rate is $22.50 per hour
How to find Unit RateUnit rate of a relationship between two variables, x and y, that are proportionally related can be found using k = y/x, where k is the unit rate.
Given that:
x = hours he worked
y = his total earnings
We are told that (4, 90) is a point on the graph.
Using the point, (4, 90), we can find the unit rate as shown below:
k = y/x = 90/4
k = 22.5
Therefore, the statement that is true about the graph as it relates the unit rate is:
d. The unit rate is $22.50 per hour

sqrt( 74)
8.602
Step-by-step explanation:
To find the distance between the two points we use the formula
d = sqrt( ( x2-x1)^2 +(y2-y1)^2)
= sqrt( ( 3- -2)^2 + ( -2 -5)^2)
= sqrt( (3+2)^2 + ( -7)^2)
= sqrt( 5^2 (-7)^2)
= sqrt( 25+49)
= sqrt( 74)

Which of the following is equivalent to:
−−(2+5)−(3−7)?
Answer:
You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!

Ms. Rowlen went Black Friday shopping and she bought a flat screen TV that originally costs $259.00. She used her super Savings Coupon of 45%, how much did Ms. Rowlen pay for the TV?
If she used a coupon of 45%, the price markdown would be 116.55. You must subtract the markdown from the original cost to discover the amount she had to spend.
259.00 - 116.55 = 142.45
So, Ms Rowlen had to spend 142.45 on the TV.
4x²-8xy
factorise completely
Answer:
4x (x - 2y)
Step-by-step explanation:
Pull out what factors they both have and put it outside the parentheses, put the rest inside after dividing.
The factoring of the algebraic form 4x² - 8xy is 4x(x - 2y).
INTRODUCTION~Algebraic Forms and their ElementsAlgebraic form is a mathematical form whose presentation involves symbols or letters to represent unknown numbers.
Elements of Algebra:1. Variables, Constants and Coefficients
Pay attention to the algebraic form 3x + 2y + 3
From the algebraic form above, x and y are variables (variables), while the number 3 is a constant. A variable is a substitute symbol for a number whose value is not clearly known. While constants are terms of an algebraic form in the form of numbers and do not contain variables.
And what is meant by the coefficient is the constant factor of a term in algebraic form. The coefficient on the 3x term is 3, on the 2y term it is 2.
2. Terms and Factors
» The term is part of the algebraic form which is limited by the operation of addition (+) or difference (-). The term one is an algebraic form that is not connected by the operation of addition or difference.
Example: 2x, 2a², -4xy, . . .
» Term two is an algebraic form that is connected by an operation of sum or difference.
Example: 2x + 3, a² - 4, 3x² - 4x, . . .
» Similar terms in algebraic form are terms that have the same variable and the same power.
Example:
2a is similar to 3a, 4a, etc.
» Factors are part of the algebraic form that is restricted to multiplication operations.
Example: 5n = 5 × n, 5 and n are factors of 4n, respectively.
Calculation Operations on Algebraic Form1. Addition and subtraction of algebraic forms can only be done on similar terms.
2. Multiplication and division of algebraic forms.
Multiply two terms by constants or variables.
Example:
3 (4y + 5)
= (3 × 4y) + (3 × 5)
= 12y + 15
Division of two terms with a variable or constant, for example:
(8y+4)/2 = 8y/2 + 4/2 = 4y + 2
DISCUSSION4x² - 8xy
= 4xx - 8xy
= 4xx + 2 × 4xy
= 4x (x - 2y)
Conclusion:So, The factoring of the algebraic form 4x² - 8xy is 4x(x - 2y).

A system of equations is created by using the line represented by 2x+4y = 0 and the line represented by the data in
the table below.
What is the x-value of the solution to the system?
Step-by-step explanation:
the answer 0 I think that's it
Answer:
2
Step-by-step explanation:
The slope of the line represented by the table is ...
m = (y2 -y1)/(x2 -x1)
m = (-4 -8)/(3 -(-1)) = -12/4 = -3
The y-intercept of that line is ...
b = y -mx
b = 8 -(-3)(1) = 5
Then the slope-intercept equation of the line represented by the table is ...
y = mx +b
y = -3x +5
Substituting that into the equation for the given line, we have ...
2x +4(-3x+5) = 0
2x -12x +20 = 0
20 = 10x . . . . . . . . add 10x and simplify
2 = x . . . . . . . . . . divide by 2
The x-value of the solution to the system of equations is x = 2.
