I have written 2x-18=-2y+12
Then I added 18 is that correct so far.

Answers

Answer:

[tex]3[/tex]

Step-by-step explanation:

[tex]2x-18=-2y+12[/tex]

[tex]y=12[/tex]

[tex]2x-18=-2(12)+12[/tex]

[tex]2x-18=-24+12[/tex]

[tex]2x-18=-12[/tex]

[tex]2x-18+18=-12+18[/tex]

[tex]2x=6[/tex]

[tex]\frac{2x}{2} =\frac{6}{2}[/tex]

[tex]x=3[/tex]

Answer:

x = 3

Step-by-step explanation:

=> 2x-18 = -2y+12

Given that y = 12

Putting in the above equation to get the value of x

=> 2x-18 = -2(12)+12

=> 2x-18 = -24+12

=> 2x-18 = -12

Adding 18 to both sides

=> 2x = -12+18

=> 2x = 6

Dividing both sides by 2

=> x = 3

a number t decreased by 2 is at least 7

Answers

Answer:
t - 2 ≥ 7; t ≥ 9

Explanation:
“a number t” = t
“decreased by 2” = - 2
“Is at least 7” = ≥ 7
So, t - 2 ≥ 7

To solve for t - 2 ≥ 7, add 2 to both sides of the equation

t - 2 ≥ 7
t - 2 + 2 ≥ 7 + 2
t ≥ 9

So, t ≥ 9

x-7
2x2 - 32
DA. 7
B. 4
D C.-7
OD. -2
0 E. -4
F. 2

Answers

Answer:

B and E

Step-by-step explanation:

Given the rational expression

[tex]\frac{x-7}{2x^2-32}[/tex] ← factorise the denominator

2x² - 32 ← take out a common factor of 2 from each term

= 2(x² - 16) ← (x² - 16) is a difference of squares

= 2(x - 4)(x + 4)

The expression can now be written as

[tex]\frac{x-7}{2(x-4)(x+4)}[/tex]

The denominator of the expression cannot be zero as this would make the expression undefined. Equating the denominator to zero and solving gives the values that x cannot be.

2(x - 4)(x + 4) = 0

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 4 = 0 ⇒ x = - 4

These are the values of x that make the expression undefined.

x = 4 → B

x = - 4 → E

Solve the equation.4[x+1/3]=20

Answers

Answer:

[tex]x=\frac{14}{3}[/tex]

Step-by-step explanation:

Open the brackets.

[tex]4x +\frac{4}{3}=20[/tex]

[tex]4x=\frac{56}{3}[/tex]

[tex]x=\frac{14}{3}[/tex]

Answer:

So first we need to divide both sides by four. The four on the left side will cancel out and the right side will become 5. Next we have

x+1/3=5

Now we need to subtract both sides by 1/3. The 1/3 will cancel out and the 5 will become 4 2/3.

All we will be left with is x

x = 4 2/3

The total cost for a bucket of popcorn and 4 movie tickets is $56. The total cost for the same size bucket of popcorn and 6
movie tickets is $80. The cost of a bucket of popcorn is $8. Which equation represents the relationship between y, the total
cost of the popcorn and movie tickets, and x, the number of movie tickets that are purchased?
y = 12x + 8
y = 12x - 8
y = 14x + 8
y = 14x - 8

Answers

Answer:

y = 12x + 8

Step-by-step explanation:

You can come to this conclusion by plugging in the amount of tickets bought as x in each equation, making sure the the answer y is $56 if x = 4 and $80 if x = 6

in a triangle, what is the 3rd angle measure if the other two angles are each 60

Answers

the answer is 60. i hope this helps if it does please mark brainliest

Answer: 60 degrees

Explanation: the two other measures add up to 120 degrees. The triangle sum property states that every triangle always adds up to 180 degrees. So, 180 - 120 = 60 degrees. Therefore, the third angle measures 60 degrees.

What is the factored from of y2+6y-16

Answers

Answer:

(y + 8)(y - 2)

Step-by-step explanation:

Given

y² + 6y - 16

Consider the factors of the constant term (- 16) which sum to give the coefficient of the y- term (+ 6)

The factors are + 8 and - 2, since

8 × - 2 = - 16 and 8 - 2 = 6, thus

y² + 6y - 16 = (y + 8)(y - 2)

(y-2)(y+8) Is the answer because if you think about what two number add up to 6 and multiply to -16 it’s -2 and 8

Answer is (y-2)(y+8)

a₁ = 6

Step-by-step explanation:

The sum to n terms of a geometric sequence is

where a₁ is the first term and r the common ratio

Here [tex]S_{8}[/tex] = 1530 and r = 2, thus

[tex]\frac{a_{1}(2^{8}-1) }{2-1}[/tex] = 1530 , that is

a₁ (256 - 1) = 1530

255a₁ = 1530 ( divide both sides by 255 )

Answers

Answer:

x is 3

y is -1

Step-by-step explanation:

Solving for x:

2x+y=5

Subtract y from both sides

2x= -y+5

Subtract 5 from both sides

2x-5= -y

Multiply both sides by 4

8x-20= -4y

5x+4y=11

Subtract 4y from both sides

5x= -4y+11

Subtract 11 from both sides

5x-11= -4y

Combine equations:

5x-11=8x-20

Subtract 5x from both sides

-11=3x-20

Add 20 to both sides

9=3x

3x=9

Divide both sides by 3

x=3

Solving for y:

2x+y=5

Subtract y from both sides

2x= -y+5

-y+5=2x

Multiply both sides by 5

-5y+25=10x

5x+4y=11

Subtract 4y from both sides

5x= -4y+11

-4y+11=5x

Multiply both sides by 2

-8y+22=10x

Combine equations:

-8y+22= -5y+25

Add 8y to both sides

22=3y+25

Divide both sides by 25

-3=3y

3y= -3

Divide both sides by 3

y= -1
