Mike and Menna were instructed to graph the function y = 12 x + 1. Their graphs are shown.
KATRIN_1 [288]

Answer:

The function is y = 2x + 1.

And mike graphed the function correctly.

Menna took the point where the function touches x-axis incorrectly.

Instead of (-1/2,0), Menna took it as (-2,0)

Step-by-step explanation:

The equation y = mx +c indicates a straight line whose slope is m

And y-intercept is c.

y-intercept is nothing but the distance between origin and point where the graph crosses the y-axis (0,c).

Now, this graph crosses x-axis when y = 0.

⇒ mx + c = 0;       ⇒ x = \frac{-c}{m}.

Now, by comparing y = 2x + 1 with y = mx + c.

m=2 and c=1

⇒ the graph should crosses y-axis at (0,c) = (0,1)

And touch x-axis at (\frac{-c}{m} , 0) = (\frac{-1}{2},0)

⇒ mike graphed the function correctly.

Menna took the point where the function touches x-axis incorrectly.

Instead of (-1/2,0), Menna took it as (-2,0)

A square has a diagonal length 18 in. What is the side length of the square?
Elenna [48]

Answer:

9\sqrt{2} inches

or

12.728 inches

Step-by-step explanation:

Use Phytagorean Theorem

a^{2} +b^{2} =c^{2}

Since both all sides of a square are equal, this means that a^{2} and b^{2} are equal.

So that leaves us with:

a^{2} +a^{2} = 18^{2}

Simplify

2a^{2} = 324

Divide both sides by 2

\frac{2a^{2} }{2} =\frac{324}{2}

Simplify

a^{2} = 162

Find the square root of both sides

\sqrt{a^{2} } =\sqrt{162}

a = 9\sqrt{2}

(or if you want the decimal, rounded to the 3rd decimal place: 12.728)

Mandy has an IQ of 115. We know that the mean () IQ is 100 with a standard deviation of 15. There are 100 people in Mandy’s Alc
Alex787 [66]

Answer: 16

Step-by-step explanation:

Given : Mean : \mu=100

Standard deviation : \sigma =15

The value of z-score is given by :-

z=\dfrac{x-\mu}{\sigma}

For x= 115

z=\dfrac{115-100}{15}=1

The p-value : P(z>1)=1-P(z

Now, the number of people smarter than Many is given by :_

100\times0.1586553=15.86553\approx16

Hence, there are 16 members smarter than Mandy.

Kendra charges $11 to shovel a driveway. She shoveled 4 driveways on Saturday and then some more on Sunday. She made $143 for th
White raven [17]

Let number of driveways , she shoveled on Sunday = x

And for 4 driveways , Kendra charges = 4*11=44

Therefore,

143 = 44 + 11x

And that's the model for the given situation .

Subtracting 44 from both sides,

143-44 = 11x

99 = 11x

Dividing both sides by 11

x = 9

Therefore she shoveled 9 driveways on Sunday .
