Which line has an x-intercept of 4?
4x+y=8
-4x + y= 8
2x+ 2y = -8
-2x+2y= -8
Answer:
-2x+2y=-8
-2x+2(0)=-8
-2x=-8
x=-8/-2
x=4
(4,0)
=======================================================
Explanation:
If we plug in y = 0 and solve for x, we'll get the x intercept.
Doing so for choice A has us get
4x+y = 8
4x+0 = 8
4x = 8
x = 8/4
x = 2
So the x intercept is 2. We can rule out choice A
Through similar steps, choice B has an x intercept of x = -2, so we can rule that out as well.
Choice C leads to x = -4, so that's not the answer either.
Choice D has an x intercept of x = 4 since,
-2x+2y = -8
-2(4)+2(0) = -8
-8+0 = -8
-8 = -8
So that confirms choice D is the answer.

Find the product or quotient using only positive exponents
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]

The correct matrix addition is (m -1) + (( -12) + 0) = 12 .
Option B is correct.
What is Matrix Addition?To add two or more matrices, the basic process is matrix addition. Matrix addition is only possible if the matrices are in the same order. By order, we mean that the matrices have the same number of rows and columns. As a result, we can add the matrices' appropriate elements. Matrix addition is not possible if the order is changed.
We will add the rows:
Addition of First row
n + (4 -7) = 18
Addition of Second row
(m -1) + (( -12) + 0) = 12
Addition of Third row
(s+ 18) + (-18 - 11)= -28

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.

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.
