Step-by-step explanation:
Answer:
3.) D
4.) B
Step-by-step explanation:
Answer: x° = 20
Steps:
100 + x + 3x = 180
x + 3x = 80
4x = 80
x = 80/4
x = 20
Check:
100 + x + 3x = 180
100 + 20 + 3(20) = 180
100 + 20 + 60 = 180
180 = 180 ✅
Answer:
x = ( k+c)/5
Step-by-step explanation:
5x - c = k
Add c to each side
5x -c+c = k+c
5x = k+c
Divide by 5
5x/5= ( k+c)/5
x = ( k+c)/5
Answer:
y=
Step-by-step explanation:
Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept
y=mx+b
2=
(8)+b
2=4+b
B=-2
y=
