x = 1
y = 1
Step-by-step explanation:
y = x + 4
2x + 3y = 17
Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.
2x + 3y = 17
2x + 3 ( x + 4 ) = 17
Distributive Property
2x + 3 * x + 3 * 4 = 17
2x + 3x + 12 = 17
Combine Like Terms ( 2x and 3x)
5x + 12 = 17
Subtract 12 on both sides of the equation
5x + 12 - 12 = 17 - 12
5x = 5
Divide by 5 on both sides to isolate the variable
5x/5 = 5/5
x = 1
Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"
y = x + 4
y = 1 + 4
y = 5
x = 1
y = 5

If Holly gets 14 % off a shirt , what percent of the original price will still pay
Answers
Answer:
Holly will still pay 86% of the original price.
Step-by-step explanation:
Given
Holly gets 14% off a shirt, soDiscount = 14%To determine
What percent of the original price will still pay.
All we need is to subtract the percentage of discount from 100.
i.e.
100 - Discount = 100 - 14 = 86%
The amount left over would be what remains of the original price after Holly gets 14 % off a shirt.
Thus, Holly will still pay 86% of the original price.

Which equation, together with y =-1.5x +3, makes a system with one solution?
A.

B.
y=-1.5x
C.
2y =-3x + 6
D.
2y + 3x = 6
E.
y=-2x + 3
Answers
Answer:
Its would be E
Step-by-step explanation:
1.5x + 3 = -2x + 3 -1.5x = -2x 0.5x = 0 x = 0
Which is 0,3 and it’s only one solution.
The equation that gives the solution together with y = -1.5x + 3 is
y = -2x + 3
Option E is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 is an equation.
We have,
y = -1.5x + 3 ____(1)
y = -2x + 3 ____(2)
From (1 ) and (2) we get,
-2x + 3 = -1.5x + 3
-2x + 1.5x = 3 - 3
-0.5x = 0
x = 0
Now,
y = -2x + 3
y = 0 + 3
y = 3
Thus,
The solution is (0, 3).

At school 40% of the teachers teach English if 20 teachers teach English how many teachers work at school
Answers
Answer:
Step-by-step explanation:
Change the 40% to a decimal, which is 40/100 or also equivalent to 2/5
Then divide the number of teachers by the percentage/decimal of teachers
20/(2/5) = 100/2 = 50 total teachers
The total number of teachers in the school is 50 teachers
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the total number of teachers in the school be = A
The percentage of teachers in the school who teach English = 40 %
The total number of English teachers = 20 teachers
So the percentage equation is ,
To calculate the total number of teachers
40 percentage of total teachers = 20 English teachers
So ,
( 40 / 100 ) x A = 20
Multiply by 100 on both sides , we get
40A = 2000
Divide by 40 on both sides , we get
A = 50
Therefore , the value of A is 50
Hence , the total number of teachers in the school is 50 teachers

Step-by-step explanation:
Since QT is a midsegment then it is half of RS , that is
QT = [tex]\frac{1}{2}[/tex] RS, substitute values
y = [tex]\frac{1}{2}[/tex] (y + 42) ← multiply both sides by 2 to clear the fraction
2y = y + 42 ( subtract y from both sides )
y = 42

A. g(x)=[1/2]×-3
B. g(x)=[1/2]×+3
C. g(x)=[1/2]×-3
D. g(x)=[1/2]× +3
Answers
To shift a graph to the left you add to the x value
The answer would be B. g(x)=[1/2]×+3
The equation of g(x) = [1/2]x + 3 which is correct option (B)
What is translation of graph?A translation of a graph is a shifting of the graph either horizontally or vertically parallel to the axis.
If g(x) was translated three units to the left to create f(x)= [1/2]x, then
g(x) - 3 = f(x)
g(x) = f(x) + 3 = [1/2]x + 3
So g(x) = [1/2]x + 3
