What do the differences between the points (as shown on the graph) represent? On a coordinate plane, point B is at (2, 7) and point D is at (4, 14). StartFraction 7 over 2 EndFraction is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph. StartFraction 2 over 7 EndFraction is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph. StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1.

A set of 4 consecutive odd integers has a sum of 216. What are the integers?​

Answers

Answer:

Hope this helps!!

Step-by-step explanation:

So the four consecutive odd integers are: 51 , 53 , 55 and 57 .

If the first integer is n, then the other three are n+2,n+4 and n+6

and we have:

216=n+(n+2)+(n+4)+(n+6)=4n+12

Subtract 12 from both ends and transpose to get:

4n=204

Divide both sides by 4

to get:

n=51

So the four consecutive odd integers are:

51,53, 55 and 57.

Answers

Answer:

y = 4x + 14

Step-by-step explanation:

slope-intercept form: y = mx + b

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

To write the equation in y = mx + b form, we need to find the slope(m) and the y-intercept(b) of the equation.

To find the slope, take two points from the table(in this example I'll use points (0, 14) and (1, 18)) and input them into the slope formula:

[tex]\frac{18-14}{1-0}[/tex]

Simplify:

18 - 14 = 4

1 - 0 = 1

[tex]\frac{4}{1}=4[/tex]

The slope is 4.

To find the y-intercept, input the values of the slope and one point(in this example I'll use point (1, 18)) into the equation format and solve for b:

y = mx + b

18 = 4(1) + b

18 = 4 + b

14 = b

The y-intercept is 14.

Now that we know the slope and the y-intercept, we can write the equation:

y = 4x + 14

Question 2 An exponential model y = a.6 passes through the points (0,9) and (3,243). What are the values of a and b?​

Answers

Answer:

a = 9, b = 3

Step-by-step explanation:

The exponential function is

y = a [tex]b^{x}[/tex]

Find a and b by using the points it passes through

Using (0, 9 ) then

9 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 )

a = 9

y = 9 [tex]b^{x}[/tex]

Using (3, 243 ) then

243 = 9b³ ( divide both sides by 9 )

27 = b³ ( take the cube root of both sides )

b = [tex]\sqrt[3]{27}[/tex] = 3

y = 9[tex](3)^{x}[/tex] ← exponential equation

volume=(length*width*height)/3

Since the base of the triangle is a square, we simply know that the length and width is equal.

H = 6 ft

Solution:

V = (2*2*6)/3V = 8 ft^3

The correct answer is 8 ft^3
