Answer:
y=6-3x
Step-by-step explanation:
factor out common terms 2(3x+y)=12divide both sides by 2
3x+y=[tex]\frac{12}{2}[/tex] simplify 3x+y=6 subtract 3 from both sides
y=6-3x

Solve the equation 5x+(-2)=6x+4
Answer:
x = -6
Step-by-step explanation:
Step 1: Write out equation
5x + (-2) = 6x + 4
Step 2: Simplify
5x - 2 = 6x + 4
Step 3: Subtract 5x on both sides
-2 = x + 4
Step 4: Subtract 4 on both sides
-6 = x
Step 5: Rewrite
x = -6
Answer:
x = -6
Step-by-step explanation:
[tex]5x+(-2)=6x+4[/tex]
Open the parenthesis
[tex]+(-2) =-2\\\\5x -2 =6x+4[/tex]
Collect like terms and simplify
[tex]5x-6x =4+2\\-x =6[/tex]
Multiply through by -1
[tex]-1(-x)=-1(6)\\\\x = -6[/tex]
YALL I NEED HELP W MY HW. its asking for an example of something thats NOT A FUNCTION. i have no ideas !!! help plsss !!
Answer:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

You have $12 to spend on ride tickets (t) at the fair. Each ticket (t) costs $2. Write an
Inequality that represents the number of tickets you can purchase.*
(1 Point)
Answer:
12 less than or equal to 2
Step-by-step explanation:
The inequality for the given statement is $12 ≤ $2(n).
What is inequality?The equations with inequalities are those who have unequal sides on both sides. Unlike the equation, we compare the two values when we work with inequality. The equal sign is substituted between by being less than (or less than or equal to), larger than (or greater or equal to), or not equal to sign.
As per provided data from the question,
Total money to spent on the ride tickets = $12
Price of each ticket for a ride =$2
So, the inequality will be : $12 ≤ $2(n), here n is the number of rides.

Note : 100k = N1
So , N1.10 = 110k.
Thanks.
<3
Answer: E. N1.10
Step-by-step explanation:
18 words cost a total of 35k
48 - 18 = 30 additional words cost 2.5k each: 30 × 2.5 = 75k
35k + 75k = 110k

make y the subject of the formula x=a-2by squared
Answer:
y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]
Step-by-step explanation:
Given
x = a - 2by² ( subtract a from both sides )
x - a = - 2by² ( multiply through by - 1 to clear the leading negative )
a - x = 2by² ( divide both sides by 2b )
[tex]\frac{a-x}{2b}[/tex] = y² ( take the square root of both sides )
y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]
Making y the subject of the formula, [tex]x = a - 2by^2[/tex] , the answer would be:
[tex]\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]
Given the formula: [tex]x = a - 2by^2[/tex],
Required:
Making y the subject of the formula
This is done as shown below:
[tex]x = a - 2by^2[/tex]
Subtract a from both sides[tex]x - a = - 2by^2[/tex]
Divide both sides by -2b[tex]\frac{x - a}{-2b} = y^2[/tex]
Take the square root of both sides[tex]\sqrt{\frac{x - a}{-2b}} = y\\\\\\\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]
Therefore, making y the subject of the formula, [tex]x = a - 2by^2[/tex] , the answer would be: [tex]\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]

You are graphing Rectangle ABCD in the coordinate plane. The following are three of the vertices of the
rectangle: A(-5,–8), B(-5,0), and C(-2,0).
Answer:
The answer is -2, -8.
Step-by-step explanation:
Since the three coordinates of the vertices are A(-5,–8), B(-5,0), and C(-2,0), the fourth vertices of the rectangle will be D(-2, -8)
What is rectangle?It is described as a type of two-dimensional geometry where the angle between neighboring sides is 90 degrees. A quadrilateral of that kind is it. in two-dimensional planning geometry, the space occupied by the rectangle.
The following formula may be used to determine the area of a rectangle:
Rectangle area = length x width
It is given that the three coordinates of the rectangle are A(-5,–8), B(-5,0), and C(-2,0).
We have to find the fourth vertices coordinates of the rectangle will be D(-2, -8)
Let the fourth vertices coordinates of the rectangle will be (x,y).
Since the parallel side of the rectangle is the same. Plotting the graph we will obtain the coordinates of the D.
Thus, the fourth vertices of the rectangle will be D(-2, -8)

Answer:
4 2/4
Simplified: 4 1/2
Step-by-step explanation:
This is the answer because:
1) Since you Bob runs 3/4 mile each day, you have to multiply 3/4 with 6 because they are asking how far did Bob jog in 6 days.
2) 3/4*6 is equal to 18/4 which equivalent to 4 2/4 the simplified version is 4 1/2
The number N was increased by 20%, and then the result was again increased by 20% By what percent is the final result greater than the
original number?
E. 44%
F. 40%
G. 20%
H. 10%
Answer:
44%
Step-by-step explanation:
Suppose the original number is 100.
It is increased by 20 %, so the result will be 120.
The resulting number is again increased by 20%, which is increased by 120 *20/100, which is increased by 24. The final result will be 120+24 that is 144.
The final result is increased by 44 compared to the original number 100.
So, increase by 44%.
