What is an equation of the line that passes through the point (2,-5) and is parallel
to the line 6x + y = 6?
Step-by-step explanation:
Hey there!
Given equation is; 6x + y= 6.
6x + y -6=0........……(i)
Slope (m1) = (-coefficient of X)/(coefficient. of y)
Slope (m1) = (-6)/(1)
Therefore, slope of the equation is -6.
As per the condition of parallel lines, slope of 1st equation is equal to 2nd equation.
Therefore, m1=m2= -6
The another straight line passes through the point (2,-5). So to find the equation, use one-point formula.
(i.e (y-y1) = m2(x-x1)).
So, the equation is;
(y+5) = m2(x-2)
Now, we know that m1=m2= -6. Let's keep its value on it.
y+5 = -6(x-2)
Or, y+5 = -6x +12
Or, 6x+ y -7 = 0
Therefore, the equation which is parallel to 6x + y= 6 equation and passes through the point (2,-5) is 6x+y-7=0.
Hope it helps...

a vehicle uses 1 1/8 gallons of gas to travel 13 1/2 miles. at this rate how many miles can the vehicle travel per gallon of gas
Answer:
The vehicle can travel 12 miles per gallon of gas.
Step-by-step explanation:
The number of gallons used by a vehicle = 1 1/8 gallonsi.e.
[tex]1\frac{1}{8}=\frac{9}{8}[/tex] gallons
The number of miles traveled by a vehicle = 13 1/2 milesi.e.
[tex]13\frac{1}{2}=\frac{27}{2}[/tex] miles
Thus,
Total Gallons =9/8 gallons
Total Distance in miles = 27/2 miles
Hence:
Unit Rate = [27/2 miles] / [9/8 gallons]
= 12 miles per gallons ∵ [tex]\frac{27}{2}\div \frac{9}{8}=12[/tex]
Therefore, the vehicle can travel 12 miles per gallon of gas.

Answer:
[tex]\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7[/tex]
Step-by-step explanation:
Given
[tex]\frac{3x^6}{6x^{-1}}[/tex]
Required
Solve
In laws of indices, we have:
[tex]\frac{x^m}{x^n} = x^{m-n}[/tex]
So, the expression becomes:
[tex]\frac{3x^{6 - (-1)}}{6}[/tex]
[tex]\frac{3x^{6 +1}}{6}[/tex]
[tex]\frac{3x^7}{6}[/tex]
Divide 3 and 6 by 3
[tex]\frac{1x^7}{2}[/tex]
[tex]\frac{x^7}{2}[/tex]
This can be rewritten as:
[tex]\frac{1}{2}x^7[/tex]
Hence:
[tex]\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7[/tex]
