Answer:

C- y=2|x+2|

Step-by-step explanation:

When the number is inside the absolute value bars, the value shifts- so a positive two would move left two, and a negative two would move right two. If the number was outside of the equation, the shape would move up or down- a positive two would move the shape up two, and a negative two would move the graph down two.

The cereal box shown below is a rectangular prism. Find the surface area of the cereal box. ​
Fiesta28 [93]

Answer:

580 cm^2

Step-by-step explanation:

First, find the area of the front and back. 20*10=200

There are 2 sides with 20*10 ( front and back) so we can multiply by 2. 200*2=400

Then, the sides. 3*20=60*2=120

Then, the top and bottom 10*3=30*2=60

400+120+60=580

Amy and Ben share £21 between them in the ratio 5 : 2. How much does Amy get?
Alika [10]

Answer:

✑ \underline{ \underline{ \sf{First ,\: Let's \: learn \: about \: the \: ratio}}} :

Let us consider , there are 30 boys and 40 girls in a school. So, the ratio of number of boys to number of girls = \sf{ \frac{30}{40} =  \frac{3}{4}   = 3:4} and read as 3 is to 4. We can say , the ratio compares two of more quantities of same unit. Until two quantities have same units , it is meaningless to compare by ratio. So, to find the ratio of two quantities , it is necessary to express them in same unit or of same kind. Since , they are in division form. So ,ratio is unit less quantity. Thus , the ratio is a comparison of two quantities of the same kind in division which doesn't have any units. For example : \sf{ \frac{a}{b}} is a ratio and is read as ' a is to b ' in which ' a : is antecedent and ' b ' is called consequent.

✎ \underline{ \underline{ \sf{Now \: let's \: solve : }}}

☪ \underline{ \sf{Solution}} :

£ 21 is to be divided between Amy and Ben in the ratio 5 : 2. So, let Amy get £ 5x and Ben get £ 2x.

Then , According to the question , \text{5x +2x = 21}

Solve for x :

⇝ \sf{7x = 21}

⇝ \sf{ \frac{7x}{7}  =  \frac{21}{7} }

⇝ \sf{x = 3}

The value of x is 3. Now , substitute the value of x in 5x :

Amy received £ 5x = 5 × 3 = £ 15 .

☥ \boxed{ \boxed{ \tt{Our \: final \: answer \: is \bold{£ \: 15}}}}

Hope I helped ! ツ

Have a wonderful day / night ♡

Solve the following system of linear equations by graphing.
Oksanka [162]

Answer:

See Explanation

Step-by-step explanation:

For y=-\frac{1}{2}+3: (0,3) (2,2)

The equation is in slope intercept form. y=mx+b

The y intercept is 3.

The slope is 1/2.

Moving one unit down and 2 units to the right, we get (2,2)

For y=2x-2: (0,-2) (1,0)

The y intercept is -2.

The slope is 2.

Moving 2 units up and 1 unit to the right, we get (1,0)

What is the slope of the line that<br> contains the points (13,-2) and (3.-2)
Allushta [10]

Points are

  • (13,-2)
  • (3,-2)

\boxed{\sf Slope(m)=\dfrac{y_2-y_1}{x_2-x_1}}

\\ \sf\longmapsto m=\dfrac{3-13}{-2+2}

\\ \sf\longmapsto m=\dfrac{-10}{0}

\\ \sf\longmapsto m=0
