Answer:
Step-by-step explanation:
<u>Given formula:</u>
- 4y= -kx - 2, where slope is 4
<u>Slope-intercept formula is:</u>
- y = mx + b, where m is the slope
<u>Finding slope by bringing the formula to the same format as above:</u>
- 4y = -kx - 2
- y = -k/4x - 1/2
<u>Slope is -k/4 and comparing it with the given:</u>
Basically, we are trying to find the third number in the pattern. The pattern is - -4, -2, -12, -14 and so on. We can see that the third number is -12, which is a₃. Therefore, the answer is C) -12. Hope this helped!
The answer is 60.
You must first solve what is in parentheses.
3 (20)
60
Answer:
180
Step-by-step explanation:
Area of troiangle=180
A+B+C=180
22+90+B=90
112+B=180
B=180-112
B=68
perimeter=A+B+C
22+90+68=180
What you should do first is simplify the equation into the y = mx + b format. Move 2x to the other side. Know that in doing this, 2x must become the opposite of what it currently is (-2) in order for the equation to remain true. We also have to take away the '10' because the line is parallel, not exactly the same, which means a different y intercept. This looks like:

Next, simplify y to make things easier. This can be done by dividing both sides by 5, like so:

What you should also know is that if a line is parallel to another, then this means the slope has to be the same because they both have the same changes in rise and run. With this in mind, simply plug in the x and y values.



Add 2 to both sides to isolate b.

Which means that -2 = b.
Now that we have the y intercept, we can write the equation of the line, which is
.
