Hope this helps
Step-by-step explanation:
Page 1:
I'm not sure about the first page but here is what I think.
Increased by a value of 3.
Figure 0, is most likely 2 blocks.
Starting value = 2
Growth = 3
y= 3x + 2
Fill in the values to get y.
For example, 3(52) + 2
The rate of change is 3
The y - intercept is 2
The equation of the line is y= 3x + 2
Page 2:
I assuming that the y-intercept is -5 considering it is with 0.
Looking at 10 I see 25. What times 10, subtracted by 5 will get you 25?
3
So I assume that the equation is 3x - 5. Apply this equation to 6 and 0 to see if it is correct.
3(6) - 5 = 13. Now apply this to the other values to get the rest of the chart.
Not sure what the x means in the last input
Red Line
<em>Slope:</em> 3
<em>y-intercept:</em> 4
<em>Equation:</em><em> </em>y = 3x + 4
Blue Line
<em>Slope: </em> (-1/3)
<em>y-intercept: </em>-4
<em>Equation: </em>y = (-1/3) - 4
35 and 41 are two consecutive numbers
I think it's would be opened downwards I'm not sure sorry
Solve for z:
42 = -7 (z - 3)
42 = -7 (z - 3) is equivalent to -7 (z - 3) = 42:
-7 (z - 3) = 42
Divide both sides of -7 (z - 3) = 42 by -7:
(-7 (z - 3))/(-7) = 42/(-7)
(-7)/(-7) = 1:
z - 3 = 42/(-7)
The gcd of 42 and -7 is 7, so 42/(-7) = (7×6)/(7 (-1)) = 7/7×6/(-1) = 6/(-1):
z - 3 = 6/(-1)
Multiply numerator and denominator of 6/(-1) by -1:
z - 3 = -6
Add 3 to both sides:
z + (3 - 3) = 3 - 6
3 - 3 = 0:
z = 3 - 6
3 - 6 = -3:
Answer: z = -3
