Answer:
n=14
Step-by-step explanation:
-6=(n/-14)-5
-6+5 = n/-14
-1= n/-14
cross multiplication and striking of negative sign from both side.
n=14
Answer: x=3, y=4
Step-by-step explanation:
We are going to use the elimination method to solve this since the x values have inverse of each other. We are going to add the 2nd equation to the 1st and we will get: y=-4 then plug y=-4 into one of the equations, then solve for x. 4(x)+5(-4)=-8, 4x-20=-8, 4x=12, x=3. So x=3, y=4
Answer:
12 and 4
Step-by-step explanation:
12 × 4 = 48
12 ÷4 = 3

Answer:
y=-1/2x+7/2
Step-by-step explanation:
two lines are perpendicular if the product of the slopes is equal to -1
the slope for y=2x+4 is 2
2*x=-1
x=-1/2
the formula for the slope is
(y2-y1)/(x2-x1)=m
we know y1 and x1
(y+5)/(x+3)=-1/2
y+5=x+3/2
2y+10=x+3
2y=x-7
y=-1/2x+7/2
