Suzie solves the equation below:
x2 + 4x - 12 = 2
(x - 2)(x + 6) = 2,
by setting x -2 = 0 and x + 6 = 0.
Her solutions are x = 2 and x = -6.
Is Suzie correct? Why or why not?

Answers

Answer 1

Answer:

Suzie's answers are incorrect.

Step-by-step explanation:

x^2+4x-12=2

           +12  +12

x^2+4x=14

(if we put Suzie's answer in for x)-

2^2+4(2)=14

4+8=14

Suzie's first answer is incorrect (4+8=12)

Let's try the next one with Suzie's answer

(-6-2)(-6+6)=2

(-8)(0)=2

This answer is also incorrect. (-8*0=0)

The number of laundries that need to be washed is 46.5%.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

The number of laundries Mr. Barnes washed = 2/7.

This means,

= 2/7 x 100

= 28.5%

The number of laundries her son washed = 1/4.

This means,

= 1/4 x 100

= 25%

We see that,

Her son washed the most laundry.

The number of laundry needs to be washed.

= 100% - (28.5% + 25%)

= 100% - 53.5%

= 46.5%

Thus,

Her son washed the most laundry.

The number of laundries that need to be washed is 46.5%.

What is the image of (2, 1) after a dilation by a scale factor of 4 centered at the
origin?
HELP

Answers

Answer:

The image of the point is (8, 4)

Step-by-step explanation:

If the point (x, y) dilated by a scale factor k centered at the origin, then its image is (kx, ky)

Let us solve the question

∵ The point is (2, 1)

x = 2 and y = 1

∵ The point dilated by a scale factor of 4 centered at the origin

k = 4

→ By using the rule above multiply each coordinate of the point by 4

∵ The image of the point is (kx, ky)

∵ kx = 4 × 2

kx = 8

∵ ky = 4 × 1

ky = 4

The image of the point is (8, 4)

Answers

Given:

The function is

[tex]y=3x[/tex]

Domain of the function is {9, 15, 18, 21, 27}.

To find:

The range of the function.

Solution:

We have,

[tex]y=3x[/tex]

Domain is set of input (x-values) and range is the set of output (y-values).

Domain =  {9, 15, 18, 21, 27}

For x=9,

[tex]y=3(9)=27[/tex]

For x=15,

[tex]y=3(15)=45[/tex]

For x=18,

[tex]y=3(18)=54[/tex]

For x=21,

[tex]y=3(21)=63[/tex]

For x=27,

[tex]y=3(27)=81[/tex]

So, the y-values are 27, 45, 54, 63, 81.

Therefore, the range of the function is {27, 45, 54, 63, 81}.

Answers

Answer:

[tex]\huge\boxed{y= \frac{r-p}{t-q}}[/tex]

Step-by-step explanation:

In order to solve for y in this equation, we can algebraically manipulate it to isolate y one one side of the equation.

Step 1: Subtract [tex]p[/tex] from both sides of the equation.

[tex]ty - qy + p - p = r[/tex] [tex]ty-qy=r - p[/tex]  

Step 2: Factor out the common term [tex]y[/tex] from the left side

[tex]y( t-q ) = r-p[/tex]

Step 3: Divide both sides by [tex]t-q[/tex]

[tex]\frac{y(t-q)}{t-q} = \frac{r-p}{t-q}[/tex] [tex]y = \frac{r-p}{ t-q}[/tex]

Equation 2:

Answers

Answer:

the red skittles be 44 and yellow skittles be 17

Step-by-step explanation:

The computation of the number of each color are in the bowl is as follows;

Let us assume the red skittles be y

And, the yellow skittles be x

The first equation is

x + y = 61

And, the second equation is

y = 2x + 10

Now put the second equation in the first equation

x + 2x + 10 = 61

3x = 51

x = 51 ÷ 3

= 17

And, y = 2 (17) + 10

= 34 + 10

= 44

Hence, the red skittles be 44 and yellow skittles be 17
