Hello,
1) Finding the slope of the line passing throught the 2 points:
m=(-8-6)/(7-2)=-14/5.
A perpendicular line has a slope of -1/m=5/14
So the line searched has for equation:
y+1=(x-2)*5/14
or 10x-28y+73=0
Answer:
C
Step-by-step explanation:
(My answer is in the picture. Hope it helps ^-^)
Answer:
2 to the 20th power over 3 to the 12th power
Step-by-step explanation:
Numerator: base = 2. Power=5*4=20
Denominator :base 3 Power=3*4=12
Answer:
X=6
Step-by-step explanation:
add 5 on both sides then 5=1=6 so X=6
DENOTING
Eqn 1: 3x+4y=58
Eqn 2: 1x+3y=36
TRANSLATING
(Multiply Eqn 2 by 3)
Eqn 3: 3x+9y=108
ELIMINATION
(Subtract Eqn 3 from Eqn 2)
Eqn 4: -5y=-50
Divide both sides by -5 to derive the value of y.
y=10
SUBSTITUTION
(Substitute the value of y to any of the first two equations)
3x+4(3)=58
3x=58-12
3x=46
x=46/3 or 15 1/3
