Step-by-step explanation:
m∠3 = 7x - 10
m∠6 = 5x + 10
m∠3 = m∠6
7x - 10 = 5x + 10
7x - 5x = 10 + 10
2x = 20
x = 20/2 = 10°
I know I got the last one wrong, so I will hopefully get this one right
I am not that great with Proportional and Not Proportional, but
1. Y is 0.5 times x
2. Y is 1.5 times x
Answer:
-17
Step-by-step explanation:
8x -2y= 12
<em>Divide</em><em> </em><em>the</em><em> </em><em>whole</em><em> </em><em>equation</em><em> </em><em>by</em><em> </em><em>2</em><em>:</em>
4x -y= 6
<em>Rewrite the equation into the slope-intercept form (y=mx+c, where m is the gradient while c is the y-intercept).</em>
-y= -4x +6
y= 4x -6
Thus, gradient of given line= 4.
Since parallel lines have the same gradient, gradient of line= 4.
y= 4x +c
<em>To find the y-intercept of the lone, substitute a pair of coordinates.</em>
When x=5, y=3,
3= 4(5) +c
3= 20 +c
c= 3 -20
c= -17
Thus, the y-intercept of the line is -17.
