Answer: 2

Step-by-step explanation: The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula

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

m = (1 - (-3))/(3 - 1)

m = 4/2

m = 2

We want to create a linear equation to model the given situation.

A) c(r) = $6.00 + $1.50*r

B) 19 rides.

We know that the carnival charges $6.00 for entry plus $1.50 for each ride.

A) With the given information we can see that if you ride for r rides, then the cost equation will be:

c(r) = $6.00 + $1.50*r

Where c(r) is the cost for going to the carnival and doing r rides.

B) If you have $35.00, then we can solve:

c(r) = $35.00 =  $6.00 + $1.50*r

Now we can solve the equation for r.

$35.00 =  $6.00 + $1.50*r

$35.00 -  $6.00 = $1.50*r

$29.00 = $1.50*r

$29.00/$1.50 = r = 19.33

Rounding to the next whole number we get: r = 19

This means that with $35.00, Dennis could go to 19 rides.

Answer:

Step-by-step explanation:

The quadrilaterals that must have at least one pair of parallel sides include all of the following except trapezoid. This implies Rectangle, Square, Parallelogram, Kite, Rhombus

A quadrilateral is a four-sided polygon with four edges and four corners in geometry. The word comes from the Latin words quadri, a variant of four, and latus, which means "side." A quadrilateral is a closed shape that has four sides, four vertices, and four angles. It's made by connecting four non-collinear points. The sum of quadrilateral interior angles is always 360 degrees.

A rectangle is a quadrilateral with four right angles in Euclidean plane geometry. It can also be defined as an equiangular quadrilateral because all of its angles are equal; or a parallelogram with a right angle. A square is a rectangle with four equal-length sides.

A parallelogram is a simple quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposite or facing sides are equal in length, and its opposite angles are equal in size.

Answer:

-3(n + 2)= 15

Step-by-step explanation:

Based on this question, we know that the equation involves multiplication. Here we start our equation with -3!

Then it says "times the sum of a number and two" So let's just say the "number" is "n". The word "sum" means the answer to an addition problem, thus we know that we are adding "n" and 2. Let's put that in parenthesis!

-3(n+2)

And it says "is fifteen" which also means "equals to fifteen"

Therefore, the answer is:

-3(n + 2) = 15

Answer:

(2,2)

Step-by-step explanation:

To draw a graph you find the y value for a couple of x values. For a linear equation like the one given, two points are enough because the graph is always a straight line.

First graph

First, convert the equation into the y=... form:

x - y = 0 => y = x

No choose two x values at random, e.g., 0 and 5:

for x=0, you find y=0, so (0,0) is a point on  the graph

for x=5, you find y=5, so (5,5) is a point on the graph

Now plot these two points and draw a line through them.

Second graph

First, convert the equation into the y=... form:

x + y = 4 => y = 4 - x

No choose two x values at random, e.g., 0 and 5:

for x=0, you find y=4, so (0,4) is a point on  the graph

for x=5, you find y=-1, so (5,-1) is a point on the graph

Now plot these two points and draw a line through them.

Explanation:

So the equation it's asking you to do is like y=kx ,

so your k is 2/3.

y=2/3x

Then for x it's 3 1/2.

y= 2/3(3 1/2)

now your "y" is any variable to hold the other too.
