Answer:
20 = AC
Step-by-step explanation:
AB+BC = AC
11+9 = AC
20 = AC
Answer:
He had been in a hospital with friends since his birth
No, line graphs are used only to show change over time
Answer:
If $300 is 200%, half of that would be 100%. Thus, $150 is the correct answer.
Step-by-step explanation:
Answer:
y = 2x
the formula for linear equations are y = mx+c,
where m is the gradient,
and c is the y-intercept
to find m (the gradient):
1. pick to points on the graph (eg. -2,-4 and 2,4)
2 substitute the values into the formula for gradient y2-y1/x2-x1.
m = y2-y1/x1-x2
= -4 -4/-2-2
= -8/-4
= 2
to find c (y-intercept):
- the y-intercept is where the graph cuts the y axis
- in this graph, the y-intercept is 0
hence,
c = 0
substitute m = 2 and c = 0 to y = mx+c,
y = 2x + 0
y = 2x
hence, the equation that best represents the relationship shown in the graph is y = 2x.
