Rosa recorded the height (in centimeters) of a pea plant over a 10-day period for a science experiment. Please help me with this
katrin [286]

Answer:

option a)

y = m(0.5) + 1.8

Step-by-step explanation:

Equation

<h3>y = mx + c</h3>

represent the equation of straight line

here m = gradient of straight line

         c = y-intercept

First find the gradient of the graph

<h3>m = y2 - y1 / x2 - x1</h3>

    = 4 - 3 / 4 - 2

    = 1 / 2

Put the values in the equation of straight line

y =mx + c

4 = 1/2(4) + c

c = 2

y = 1/2x + 2

which is approximately equal to y = 0.5x + 1.8

How do you solve them
Andrew [12]
#1)     9=6 - 3 |4p + 9| now we're going to distribute
          
          9= 6 - 12p - 27
         
          9= 6 - 27 - 12p
          
          9= - 21 - 12p
  
          9 + 21= -12p
   
          30= - 12p  Now you are going to divide both side by -12

         -12:30 = -12:-12p

          -5/2= p final answer

#2)  - |1 + 4a| = -13   now you going to change the sign
        
        -1 - 4a = -13

        -4a = -13 + 1

        -4a = -12  now divide both side by -4 

        -4a:-4 = -12:-4

a = 3 final answer
