Answer:
x+(x+30)=72
Step-by-step explanation:
if x is the smaller number and y is the bigger number, then according to the condition (one number is 30 more than the other) y=x+30.
It the sum of the two numbers is 72, then x+y=72.
After substitution y=x+30:
x+(x+30)=72; - the required equation.
⇔ 2x=42; ⇒ x=21 (it is the smaller number)
y=51 (it is the bigger number).
Answer:
2x + 5y + 28 = 0
Step-by-step explanation:
since they are perpendicular,
m1 ×m2 = -1
5/2 × m2 = -1
m2 = -2/5
now,
y -y1 = M (x-x1)
y - (-4) = -2/5 ( x - (-4) )
y +4 = -2/5 ( x + 4 )
5 ( y +4 ) = -2 ( x+4)
5y +20 = -2x - 8
2x + 5y +20 + 8 =0
2x + 5y + 28 = 0
v = -7
All we need to do is get the variable on one side of the equation and simplify:
5 + 4v = -23
4v = -28
v = -7
