Answer:
Step-by-step explanation:
The graph of a linear relationship consists of the x and y values. The y values are plotted on the vertical axis against the x values on the horizontal axis. A change in the values of x lead to a corresponding change in the value of y. The correct options are
. I. The graphs of all linear relationships are a line. They are sometimes called straight line graphs
III. The tables of all linear relationships have a constant rate of change. This represents the slope
The true statement is
I and III only
Answer: y = 2x-2 / you pass the y-intercept -2 and go up by 2/1
Step-by-step explanation:
Answer:
$29,900
Growth
22%
Step-by-step explanation:
Initial value is when t = 0
v(0) = 29900(1.22)^0
v(0) = 29900(1)
v(0) = 29900
-------------------------
Growth
because 1.22 is greater than 1
----------------------------
Yearly value change
1.22 - 1 = 0.22
0.22 * 100 = 22
22%
<span>437 = (21 + x)(21 - x), then x = 2, -2</span>
Let x be the length and y be the width2x + 2y = 40x + y = 20change that into y = mx + b formy= 20 – x
Area =xy = x (20-x) = 20x - x^2Area=-x^2+20xcomplete the square:Area=-(x^2 – 20x + 100) +100=-(x - 10)^2 + 100This is an calculation of a parabola that opens downward with vertex at (10,100), which means maximum area of 100 happens when x, the length=10)Dimensions of the rectangle with maximum area? 10 yds. by 10 yds., a square.
