Use the table to draw the graph of height(y-axis) against week(x-axis).
The graph is a straight line. 
Find the gradient of the graph as the first step.
Gradient = (y2-y1)/(x2-x1)

              = (17-12)/(4-2)
              = 5/2
Use this gradient to find the equation of the line. Use one of the point from the table (e.g. (8,27)) and another general point (x,y).

∴5/2=(y-27)/(8-x)
   5/2 (x-8) = y-27
    (5/2)x - 20 = y-27
    
   y=(5/2)x - 20 + 27

  y = (5/2)x + 7

The answer is A

Answer:
y = \frac{5}{2} x + 7

Explanation:
The general form of the linear equation is:
y = mx + c
where:
m is the slope
c is the y-intercept

1- getting the slope:
slope can be calculated as follows:
m = \frac{y2 - y1}{x2 - x1}

I will use the points (2,12) and (8,27) to get the slope. You can choose any other two points and you will get the same answer.
m = \frac{27-12}{8-2} =  \frac{5}{2}

The equation of the line now is:
y = \frac{5}{2} x + c

2- getting the y-intercept:
To get the y-intercept (c), we will use any of the given points, substitute in teh equation and solve for c.
I will use the point (6,22) as follows:
y = \frac{5}{2} x + c

22 = \frac{5}{2} (6) + c

22 = 15 + c
c = 7

Based on teh above, the equation of the line is:
y = \frac{5}{2} x + 7

Hope this helps :)

Answer:

A=38.88 or 38.9

Step-by-step explanation:

If both are similar then the 9 and the 7.2 are the same

9-7.2= 1.8

9x6=54

7.2-1.8=5.4

7.2x5.4=38.88 or 38.9

Solve the system of equations using substitution.
Lynna [10]

Answer:

(6,12)

Step-by-step explanation:

Substitute the value of y into y=2x:

x+6=2x

x=6

Substitute x into the equation of y=2x

y = 2*6 = 12

(6,12)

Eight less than four times a number is less then 56. What are the possible values of that number?
Mashutka [201]

Answer: B. X<12

Step-by-step explanation:

First we need to find out what number multipled by 4 is less than 56

4 x 12 = 48

56-48 = 8

And 4 is lower/less than 12 so that's why it's B
