7x+12+6x-2=-4
7x-6x=-4-12+2
13x=-14
x=-14 divide 13
x=-14 over 13 put 14 over 13 in a fraction
Answer:
We have to find point that partition line segment AB with end points (-5,3) (-1,-5) in ratio 1:3
Assume (-5,3) as ( a,b)
Assume (-1,-5) as (c,d)
Assume ratio 1:3 as m:n
Step-by-step explanation:
Remember this formula
Partition point =( mc + na)/m+ n , ( md+ nb)/m+n
=[ (1)(-1)+ 3(-5)]/1+3, ( 1(-5) + 3(3))/1+3
= -1 -15)/4,( -5 + 9)/4
= -16/4, 4/4
= -4, 1
Answer:
x²
Step-by-step explanation:
Let "d" represent the divisor (what goes in the blank). Then you have ...
... (x²y)/d = y
Multiplying by d gives ...
... x²y = yd
And dividing by y gives the desired value:
... x² = d
The divisor is x².
Answer: 24 cm
Step-by-step explanation:
The formula for calculate the area of a triangle is:
Where b is the base and h is the height.
Then if the base of the triangle is 5 times the height:
Substitute the above into the formula and solve for the height. Therefore, you obtain that the height is:
