Answer:
Step-by-step explanation:
Given equation is 2x+y=4 .so slope(m1) = - coefficient of x / coefficient of y= -2/1=-2
- we have slope of the line perpendicular to the other line is m1*m2=-1\
- then slope of the line perpendicular to the line 2x+y=4 is -2*m2=-1\
- then -2/-1=m2 therefore m2 =2 .
What do you need with this, I am happy to help I just do not know how?
Answer:
4th option
Step-by-step explanation:
Given that the relationship is proportional then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 48 , x = 2.5 , then
48 = 2.5k ( divide both sides by 2.5 )
19.2 = k
y = 19.2x ← equation of proportion
Answer:
Q = (9, 4 )
Step-by-step explanation:
Use the midpoint formula and equate to the coordinates of the midpoint.
M = (
) , (
)
let the coordinates of Q = (x, y ) , R = (- 7, 0 ) , then
= 1 ( multiply both sides by 2 )
x - 7 = 2 ( add 7 to both sides )
x = 9
and
= 2 ( multiply both sides by 2 )
y = 4
Thus Q = (9, 4 )
