EXPLANATION
Let us find the gradient of the line:
by rewriting it in the slope intercept form.
We divide through by 4 now;
This is now in the form;
where
is he slope.
This implies that the slope of the line that is perpendicular to this line will be the negative reciprocal of .
Thus the perpendicular line has slope,
.
Let the perpendicular line have equation,
When we substitute the slope we have;
We substitute the point. 
to find c.
We substitute c to obtain;

Answer:
he can paint 8 chairs
Step-by-step explanation:
he has 78/10 liters of paint he uses 6/10 which makes it 72/10 and each chair needs 9/10 paint 9 times 8=72
Answer:
-5
Step-by-step explanation:
ab = dc
x+15= 3x+25
2x = -10
x = -5
substituting in ad and bc
-10+18 = 8
3-(-5)=3+5=8
Translating that problem into an equation with x as a variable we get 3x + x +10 = 22. Combine like terms to get 4x + 10 = 22. Subtract 10 on both sides to get 4x = 12. Divide by 4 on both sides to get x = 3.
Now to plug in. The first number was represented by 3x. So substituting 3 for the x we get 3(3) = 9. And again for the second number represented by x+10, 3+10 = 13.
Your numbers are 9 and 13. To check just add them together. 13 + 9 is 22, I'll save ya the effort.
The answer is 2
