Answer:

0

Step-by-step explanation:

The slope of the line is 0 as it is parallel to x-axis.

Slope = (y2 - y1)/(x2 - x1)

= (2-2)/(4-(-2))

= 0

Answer:

Slope = 0

Step-by-step explanation:

Taking any two points.

(x1,y1) = (3,0)

(x2,y2) = (-1,0)

Now,

\displaystyle Slope = \frac{y_2-y_1}{x_2-x_1} \\\\Slope = \frac{0-0}{-1-3} \\\\Slope = \frac{0}{-4} \\\\Slope = 0\\\\\rule[225]{225}{2}

Hope this helped!

Which situation below would represent a negative rate of change:
uranmaximum [27]

Answer: John's situation

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each situation.

John’s situation:

The amount of money that John has (y) is equal to his school account (40) minus the product of the number of days (x) and the amount he spends per day( 3)

y =40-3x

As days pass by, John has less money (negative rate of change)

Judy's situation

The amount of money that Judy has in her savings account (y) is equal to the product of the number of days (x) and the amount he saves per day (20/2)

y = x (20/2)

PLEASE HELP WILL MARK BRAINLIEST!!
Gre4nikov [31]

Answer:

Explanation below.

Step-by-step explanation:

1. a. \sqrt{x} =12

  b. \sqrt{x} ^{2}=12^{2}

  c. x=144

2. a. \sqrt{x^{2} } =\sqrt{196}

   b. x= 14

3.  

\sqrt{x} -4 +4= 8+4\\\sqrt{x} =12\\x= 3.46410161514  \\or  \\2\sqrt{3}

4.

2(x^{2} +3)=398\\x^{2} +3= 199\\x^{2} =196\\x=14

Which is bigger 3/4 or 2/3
tia_tia [17]
When we make it into a common denominator, find a common multiple between the denominators. For this instance, it is 3/4=9/12 2/3=8/12 When we see it with a common denominator, 3/4 is bigger than 2/3.

Can anyone tell me why by direct substitution of x, the equation (circled ones) equals to the indeterminate form, 0/0? When you
Katena32 [7]

Answer:

See explanation and hopefully it answers your question.

Basically because the expression has a hole at x=3.

Step-by-step explanation:

Let h(x)=( x^2-k ) / ( hx-15 )

This function, h, has a hole in the curve at hx-15=0 if it also makes the numerator 0 for the same x value.

Solving for x in that equation:

Adding 15 on both sides:

hx=15

Dividing both sides by h:

x=15/h

For it be a hole, you also must have the numerator is zero at x=15/h.

x^2-k=0 at x=15/h gives:

(15/h)^2-k=0

225/h^2-k=0

k=225/h^2

So if we wanted to evaluate the following limit:

Lim x->15/h ( x^2-k ) / ( hx-15 )

Or

Lim x->15/h ( x^2-(225/h^2) ) / ( hx-15 ) you couldn't use direct substitution because of the hole at x=15/h.

We were ask to evaluate

Lim x->3 ( x^2-k ) / ( hx-15 )

Comparing the two limits h=5 and k=225/h^2=225/25=9.
