Answer:
17.3 because it was 17.25 so you round
Well I'm not sure what the answer would be since I'm not that smart but I did get the answer of 90, I did this by dividing 72 by 80 which equals .9 and I multiplied that by 100 and got 90.
Answer:
T depends on what y equals. -1/4y, i guess
Step-by-step explanation:
Let x represent the smaller angle. Then the larger one is 20+4x. Since they are complementary, their sum is 90. (All measures are degrees.)
90 = x + (20+4x)
90 = 5x +20
70 = 5x
14 = x
The smaller angle is 14°.
The larger angle is 76°.
Answer:
We conclude the equation is linear because it can be rewritten in the form
.
Hence, option D is correct.
Step-by-step explanation:
The slope-intercept form of the line or linear equation
where
is the slope
is the y-intercept
<u>Important Tip:</u>
The graph of a linear equation is always a straight line.
Convert the given equation in the slope-intercept form
![18x + 9y = -416](https://tex.z-dn.net/?f=18x%20%2B%209y%20%3D%20-416)
subtract 18x from both sides
![18x+9y-18x = - 18x-416](https://tex.z-dn.net/?f=18x%2B9y-18x%20%3D%20-%2018x-416)
simplify
![9y = -18x - 416](https://tex.z-dn.net/?f=9y%20%3D%20-18x%20-%20416)
divide both sides by 9
![y=-2x-\frac{416}{9}](https://tex.z-dn.net/?f=y%3D-2x-%5Cfrac%7B416%7D%7B9%7D)
Now, comparing the equation
with a slop-intercept form of linear equation
- The y-intercept b = -416/9
Therefore, we conclude the equation is linear because it can be rewritten in the form
.
From the attached graph, is also clear that the graph of the equation
is a straight line.
Hence, option D is correct.
