Answer:
-5
Step-by-step explanation:
2(-5 +3)^2 = 8
2(-2)^2 =8
2(-4) = 8
8 = 8
To graph a situation that would involve a linear graph, first determine your x and y axes.
The x-axis will be the independent variable, one that does not change based on other variables. An example is time.
The y-axis, the dependent variable, depends on the independent variable.
The model equation for a linear line is y = mx + b.
"m" is the slope, and the "b" is the y-intercept (where the graph crosses the x-axis at x=0).
For example, a situtation could be that Joe starts with $10 in his account and adds $5 every day to his account.
The x-axis is time in days.
The y-axis is amount of money in his account.
The slope, or rate of change is 5.
The y-intercept, the amount of money he has at x=0 (0 days) is $10.
The equation would be y = 5x + 10
To draw this, plot the y-intercept at (0, 10), and the next point would be 5 units up and one unit to the right because the slope is 5, or 5/1 (remember slope is rise over run: "rise" up 5 and "over" to the right 1).
<span>In order to answer this question you have to know two things:
-- "Complementary" angles means that they add up to 90 degrees.
-- "Supplementary" angles means that they add up to 180 degrees.
If you know these two things, then this question should be easy for you.
If you don't know them, then there is no way.
Now that I've told you these two things, you have everything you need
with which to answer the question, and I should not have to go through
the rest of the solution for you.
But you have been so generous with your valuable points, and you do have
an Irish name on March 17, so I guess I should follow it through to the end.
I'd like to dedicate this solution to the memory of the late Sir Robert Briscoe,
the first Jewish Lord Mayor of Dublin. Go raibh maith agat.
<u>Part a).</u>
Angle 'a' is 52 degrees.
Angles 'a' and 'b' are complementary angles.
That means they add up to 90 degrees.
a + b = 90
52 + b = 90
Subtract 52 from each side: <em>b =</em> (90 - 52) =<em> 38 degrees</em>
<u>Part B).</u>
Angle 'A' is still 52 degrees.
Angles 'A' and 'X' are supplementary angles.
That means they add up to 180 degrees.
A + X = 180
52 + X = 180
Subtract 52 from each side: X = (180 - 52) = <em>128 degrees</em> </span>
$ 40,768 per year....there are 52 weeks in 1 year
40,768 / 52 = $ 784 per week <==
