It should look like a vertical line on the 2 of the x axis and everything to the right would be shaded.
Hello :
1 ) the 1 quadrant : the sine, cosine and tangent are <span> positives
2) the 2 </span> quadrant : the sine is positive but cosine and tangent are negatives
3 ) the 3 quadrant : the tangent is positive but cosine and sine are negatives
4 ) the 4 quadrant : the cosine is positive but tangent and sine are negatives
The slope/ gradient of the line is -2/3 or answer c
Answer:
Step-by-step explanation:
So since triangle jkl and wyz are similar angles j and w must equal each other, angles k and y must equal each other, and angles l and z are equal. So to find x just set 4x-13 equal to 71
4x-13=71
add 13 to both sides to cancel the -13 from the left
4x=84
and divide both sides by 4 to cancel the 4 on the left
x=21
(1) 5x=-2+7y
(2) x-7y=-34
Using the method of substitution:
Isolating x from the equation (2):
(2) x-7y=-34
x-7y+7y=-34+7y
x=7y-34 (3)
Replacing x by 7y-34 in the first equation:
(1) 5x=-2+7y
5(7y-34)=-2+7y
Solving for y:
35y-170=-2+7y
35y-170+170-7y=-2+7y+170-7y
28y=168
28y/28=168/28
y=6
Replacing y by 6 in equation (3)
(3) x=7y-34
x=7(6)-34
x=42-34
x=8
Answer: The solution of the system of equations is: x=8 and y=6
