Answer:

Step-by-step explanation:

Use the 2 points for which you have both an x and y coordinate to write the equation of the line containing those 2 points.  When you get the equation, sub in the x value of 6 and solve for y.  

Begin by finding the slope of the line:

m=\frac{-13-(-5)}{-4-0}=\frac{-13+5}{-4}=\frac{-8}{-4}=2

Then use one of the points in point slope form to write the equation in slope-intercept form.  I used (0, -5).  But either point you choose will give you the exact same line...promise.

y - (-5) = 2(x - 0) and

y + 5 = 2x and

y = 2x - 5

Now sub in the x value of 6 for x and solve for y:

y = 2(6) - 5 and

y = 12 - 5 so

y = 7

Mr. Torres took his students to the dolphin show. Each row in the stadium had 11 seats. One adult sat at each end of a row, and
Katena32 [7]

Answer:

3

Step-by-step explanation:

The given data shows that only 1 row was in use. We also know that Mr. Torres is an adult. So for the ease, lets use A for Adult and S for student.

The seating must fulfill the requirements that 4 students must be between adults such that it would be "A-S-S-S-S-A"

On a row of 11 seats, this should be the searing arrangements.

A-S-S-S-S-A-S-S-S-S-A ( for 1 row).

Mr. Torres could be any A .

Which point is a solution to the inequality shown in this graph? (0,1) (3,-1)
Sonbull [250]

All points in the shaded area are answers to the inequality.  Thus you need to find the point which is in the shaded area of the graph.

Only the point (3, -1) is within range.  Thus answer D is correct.

What is the multiplicative rate of change of the exponential function represented in the table? 1.5 2.25 3.0 4.5
Sati [7]
Use the geometric sequence formula to solve for rate:
an=a1r^(n-1)

6.75=4.5r^(2-1)
6.75=4.5r
6.75/4.5=r
r= 1.5
and if you want to make sure just multiply each number by 1.5 and see if it gets you the next number
4.5 4.5×1.5=6.75 (holds true)
6.75 6.75×1.5=10.125 (holds true)
10.125 10.125×1.5=15.1875 (holds true)
15.1875

1.5 is the multiplicatice rate hope that helps :)
