Which line has an x-intercept of 4?
4x+y=8
-4x + y= 8
2x+ 2y = -8
-2x+2y= -8
Answers
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.
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
Answers
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.

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

[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]
