Solve the Quadratic Equation: 2(x - 5)^2 = 18

Answers

Answer:

x=2 or x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x2−20x+50=18

Step 2: Subtract 18 from both sides.

2x2−20x+50−18=18−18

2x2−20x+32=0

Step 3: Factor left side of equation.

2(x−2)(x−8)=0

Step 4: Set factors equal to 0.

x−2=0 or x−8=0

x=2 or x=8

Answer:

1. x = 8

2. x = 2

Step-by-step explanation:

2 • (x - 5)2 -  18  = 0

2.1     Evaluate :  (x-5)2   =    x2-10x+25

3.1     Pull out like factors :

 2x2 - 20x + 32  =   2 • (x2 - 10x + 16)

3.2     Factoring  x2 - 10x + 16

The first term is,  x2  its coefficient is  1 .

The middle term is,  -10x  its coefficient is  -10 .

The last term, "the constant", is  +16

Step-1 : Multiply the coefficient of the first term by the constant   1 • 16 = 16

Step-2 : Find two factors of  16  whose sum equals the coefficient of the middle term, which is   -10 .

     -16    +    -1    =    -17

     -8    +    -2    =    -10    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -8  and  -2

                    x2 - 8x - 2x - 16

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-8)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-8)

Step-5 : Add up the four terms of step 4 :

                   (x-2)  •  (x-8)

            Which is the desired factorization

2 • (x - 2) • (x - 8)  = 0

4.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

During an exploratory activity, a student measured the diameter and circumference of several circular objects. She recorded her data in the table below. What equation best represents this data?

y = 6.28x
y = 3.14x + 6.28
y = 3.14x
y = 6.28x + 3.14

Answers

Answer:

y=3.14x

Step-by-step explanation:

if you graph this on a calculator you can just visually see what line lines up with all the points. but you can also plug in one of the points into the equations to see if its true or not and if its true choose that equation. like use the first points (2, 6.28) and plug them into the equations and see which one is true.

The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

Given that, a student measured the diameter and circumference of several circular objects.

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

From the table we have (2.0, 6.28) and (5.3, 16.64)

Now, slope = (16.64-6.28)/(5.3-2.0)

= 10.36/3.3

= 3.14

Substitute m=3.14 and (x, y)=(2.0, 6.28) in y=mx+c, we get

6.28=3.14(2.0)+c

c=0

Substitute m=3.14 and c=0 in y=mx+c, we get

y=3.14x

The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

The answer is D
Substitute x= 0 and y=2 into the equation,
Left hand side= 2
Right hand side= 3(0)+2= 2

Because LHS= RHS, (0,2) is the solution of the equation y=3x +2

Therefore, the equation y=3x+2 represents the graph.

Step-by-step explanation:

Well what is the question?

Liam walked from his house to the school in 17 minutes. He arrived at the school at 7:50 a.m. Stephanie started walking 5 minutes after Liam left his house. She arrived at the school at 7:52 a.m. How long did it take Stephanie to walk to the school?​

Answers

Answer:

14 minutes

Step-by-step explanation:

If Liam got to school at 7:50, and it took him 17 minutes, that means he left at 7:33. Five minutes after 7:33 is 7:38, so that's when Stephanie left. She arrived at school at 7:52 am, so what we have to do is subtract 7:38 from 7:52 in order to get 14 minutes elapsed.

Which of the following equations represents the line that is graphed on the coordinate grid below?

y=−1/3x−6y is equal to negative 1 third x minus 6

y=−3x+6y is equal to negative 3 x plus 6

y=−3x+2

Answers

Answer:

y = -(1/3)x + 2

Step-by-step explanation:

Keeping in mind the equation of a line: y = mx + c

Notice three discernible points on the graph: (0,2), (3,1), (6,0).

The first and last points mentioned represent the intercept on y-axis and the intercept on x-axis respectively.

Therefore, when x = 0, y = 2. And 2 = m(0) + c

c = 2

Also, when y = 0, x = 6. And 0 = 6m + 2

6m = -2. And m = -(2/6) = -(1/3)

Therefore, y = -(1/3)x + 2

The table below shows the amount of flour and eggs you need for making different-sized batches of cookies using the same recipe.

Cups of flour Number of eggs

Batch A 3 2

Batch B 9 6

Batch C 12 8


Write an equation to describe the relationship between f, the cups of flour, and e, the number of eggs.


So to do this we have to divide cups of flour and Number of eggs.

So that means we can divide 3 / 2 = 1.5

9 / 6 = 1.5

12 / 8 = 1.5

So that means f is the cups of flour and e is the number of eggs.

So we can said we can put f / e =1.5

Cups of flour / Number of eggs = 1.5

So the answer is f / e = 1.5

f/e=1.5

Answer:

2x - 10 = 10 - 3x

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4
