Answer:
7x + 8y - 5
Step-by-step explanation:
Like terms are terms with the same variable as well as the same amount of said variable:
Set the expression:
4x + 3y - 4 + 5y + 3x - 1
4x + 3x + 3y + 5y - 4 - 1
Combine like terms:
(4x + 3x) + (3y + 5y) + (-4 - 1)
(7x) + (8y) + (-5)
7x + 8y - 5 is your answer.

Answer:
x/7 - 2 = y
Step-by-step explanation:
To find the inverse of a function, we switch f(x) and x and then solve for f(x). We thus have
x = 7f(x) + 14
subtract 14 from both sides to isolate the f(x) and its coefficient
x - 14 = 7 f(x)
divide both sides by 7 to isolate the f(x)
(x-14)/7 = f(x)
f(x) is synonymous with y here. so we havt
(x-14)/7 = y
This can also be written as
x/7 - 14/7 = y
x/7 - 2 = y

Step-by-step explanation: hope this helps :)
The composition of the transformations given in the figure is translate 4 units to the left and then reflect over the X axis.
What is Geometric Transformation?Transformation of geometrical figures or points is the manipulation of a given figure to some other way.
Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.
After translation, the original figure is shifted from a place to another place without affecting it's size.
After Reflection, figure is flipped. In other words, a figure becomes it's mirror image.
Consider the point P.
Before undergoing reflection, the figure must be above the X axis.
And the point P will be translated 4 units to the left.
After reflection, since the figure moved towards the other side of the X axis, the figure is reflected across the X axis.
Hence the missing parts are filled.

What is the solutions to the 2 system of equations? The X and Y have to be the same for both equations.
5x+4y=12
3x+6y=8
Answer:
x = 5, y = 7
Step-by-step explanation:
x – y = -2 ——— 1
5x – 4y = -3 —– 2
x = -2 + y ——— 3
3 in 2 ≈ 5(-2 + y) – 4y = -3
-10 + 5y – 4y = -3
y = -3 + 10
y = 7
Putting y = 7 in 3, we have;
x = -2 + (7)
x = 5
Hence (x, y) = (5, 7)

Answer:
she is correct
Step-by-step explanation:
because according to the Pythagorean theorem the interior of a triangle has to be 180 degrees total.
and a straight line has an angle of 180
so the inside of the C angle is 50

If the neighborhood holds 13 total games and all 50 athletes participate, how many 6-player games and how many 2-player games are played? Write and solve a system of equations .
pllzz help 20 pointsss
Answer:
13 points
Step-by-step explanation:
Equation for "There are 50 athletes signed up for a neighborhood basketball competition. Players can select to play in the 6-player games ("3 on 3") or the 2-player games ("1 on 1").
Equation for "If the neighborhood holds 13 total games and all 50 athletes participate"
How many 6 player games?
How many 2 player games?
The answer to this question is:
7 two-player games are played
6 six-player games are played
What are system of equations?
A collection of two or more equations with the same set of unknowns is referred to as a system of equations.
Systems of linear equations in two variables can be solved in one of three ways:
by graphing; by the substitution approach; or by the elimination method.Solution:
Given:
Total games = 13
Total number of athletes participated = 50
Find:
6-player games played = ?
2-player games played = ?
Step-1:
let x denote the total 2-player games played &
y denote the total 6-player games played.
Hence the equation for the total number of games played is:
x + y = 13 ..............eq(1)
Now, the equation for the total number of games played by the athletes is:
2x + 6y = 50............eq(2)
Further eq(2) can be reduced as-
2(x + 3y) = 50
x + 3y = 50/2
x + 3y = 25.........eq(2)
Step-2:
Solving eq(1) and eq(2) by using elimination method as follows:
x + y = 13
x + 3y = 25
Step-3:
In the elimination method positive signs changes to negative and x gets eliminated so we get the y value as:
-2y = -12
y = 6
Substituting y value in eq(1): x+ y = 13
x + 6 = 13
x = 13 - 6
x = 7
Hence we found out that total 7 two-player games and 6 six-player games were played.

Answer:
geometric
common ratio 2/3
Step-by-step explanation:
We know that the sequence is not arithmetic
3-2 =1
2-4/3 = 6/3 -4/3 = 2/3
The common difference is not the same
Now check geometric
The common ratio:
Take the second term over the first term
2/3
Now take the third term over the second term
4/3 ÷ 2
4/3 * 1/2 = 2/3
The common ratio is the same so the sequence is geometric with a common ratio of 2/3

Step-by-step explanation:
Students at a local high school travel to school by car, bus, and bicycle. 1/5 of the 825 students Tavel by car, 48% of the students travel by bus, 0.08 of the students travel by bicycle. The remaining students travel to school by walking. How many students walk to the local high school?
Answer:
198 students walk to the local high school
Step-by-step explanation:
Total number students = 825
1/5 of the students travel by car
48% of the students travel by bus
0.08 of the students travel by bicycle
To find the number of students who wal to school we have to find the exact number of students who travel to school by car, bus and bicycle and subtract the result from the total number of students
Students who travel by car = 1/5×825
= 165 students
Students who travel by bus = 48% × 825
= 48/100 × 825
= 12/25 × 825
= 396 students
Students who travel by bicycle = 0.08 × 825
= 66
So now we add the results fo the equations above and subtract it from the total number of students to get the number of students that walk to school
Students that walk to school = 825 - (165 + 396 + 66)
= 825 - 627
= 198 students
Therefore 198 students walk to the local high-school
