What is the value of 2y- 6 if y = 12
Answer:19
Step-by-step explanation:
The answer is 19 because you need to do 12*2 and then subtract 6. 24-6=19
Answer:
18
Step-by-step explanation:
1.) 2y -6
2 ) 2(12) - 6
3.) 24 - 6
Answer ~ 18
1.) 12 equals y so put 12 in place of y
2.) Using PEMDAS, multiply 12 × 2 which equals 24.
3.) Then you subtract 6 from 24 which equals 18.
An equation and the first step in its solution are shown.
Equation: x2 + 3x – 9 = 0
Step 1: x2 + 3x + h = 9 + h
What value of h is used to solve the equation by the method of completing the square?
Answer:
The answer is either 1.5 or 0.667
Step-by-step explanation:
x2+3x-9=0
x2+3x=9
6x=9
x=1.5
or
x=667
the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]
Given :
An equation and the first step in its solution are shown.
Equation: [tex]x^2 + 3x -9 = 0[/tex]
Step 1: [tex]x^2 + 3x + h = 9 + h[/tex]
In completing the square method , we take the coefficient of x and divide it by 2 and then square it
coefficient of x is 3
divide it by 2 , so we get [tex]\frac{3}{2}[/tex]
Then we square it [tex](\frac{3}{2} )^2\\\frac{9}{4}[/tex]
Then we add it on both sides of the equation
[tex]x^2 + 3x + \frac{9}{4} = 9 + \frac{9}{4}[/tex]
So, the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]

Solve for x: -243 = -9(10 + x)
I will reward Brainliest
Answer:
x = 17
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-243 = -9(10 + x)
Step 2: Solve for x
Divide -9 on both sides: 27 = 10 + xIsolate x: 17 = xRewrite: x = 17Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -243 = -9(10 + 17)Add: -243 = -9(27)Multiply: -243 = -243Here we see that -243 does indeed equal -243.
∴ x = 17 is the solution to the equation.
Write the phrase "9 increased by a number x" as an algebraic expression
Answer:
9+x
Step-by-step explanation:
To write 9 increased by a number x, you need to know that when it says "increased by" it means adding.
So it is saying 9 is being added by x, or 9+x as an algebraic expression.
The phrase "9 increased by a number x" as an algebraic expression would be; 9+x
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We need to write the given phrase "9 increased by a number x" as an algebraic expression
Let the unknown number = x
To write 9 increased by a number x, we need to know that when it says "increased by" it means adding.
So it is saying 9 is being added by x, then
We can write it 9+x as an algebraic expression.

Jackie needs to save $125 to go to a concert. He has saved $35. He makes $7.50 an hour at his job.
Let x representing the number of hours.
Which equation and solution can be used to show how many hours jackie must work in order to have enough money to go to the concert?
A. 125x + 35 = 750; x = 5.75
B. 35 - 7.5x = 125; x = 6
C. 7.5x + 35 = 125; x = 12
D. 35x + 125 = 750; x = 18
Answer:
C
Step-by-step
Answer:
Answer is C
Step-by-step explanation:
First Jackie needs to save $125
y = 125
He already saved $35, this is our constant
He makes $7.50 an hour on his job,
Our variable x is hours
125 = 7.50x + 35
If we solve for x, we get x = 12
