Let x and y be the two numbers.
x = y - 4
2y = 5x - 10
solve the system of equations:
2y = 5(y - 4) - 10
2y = 5y - 20 - 10
-3y = -30
y = 10
x = 10 - 4 = 6
Answer:
D)
Step-by-step explanation:
It looks like the most sense
Answer:
for two lines to be perpendicular m2 = -1/m2
using the formula y= mx+c
m1 = 0
for the lines to be perpendicular to each other(m2 = -1/0 )
Note: -1/0 is undefined
using the formula y-y1 = m(x-x1)
y -6 = -1/0(x-2)
cross multiply
0 = -1(x-2)
0 = -x+2
x =2(equation of the line)
The answer is 9 I am so smart XD
To figure this out we keep in mind two rules
1. A triangles sum of angles is 180
2. An angle of a triangle can not be 0
So the answer is the following
2, 3 & 4
