If two lines represent the same line, then what is the nature of its solution?
Step-by-step explanation:
If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent .
Answer:
Infinite
Step-by-step explanation:
Solution between 2 lines is considered the point of their intersection. Now, since two lines are same (not only parallel but same), it tends to have infinite solutions.

Natalie and Lexi are recycling aluminum cans to earn money for camp. Natalie's barrel of cans weighs 115 lb., and Lexi's barrel of cans weighs 98 lb. If the barrels each weigh 8 lb. when empty, how many pounds of cans have they collected?
Answer:
197 pounds of cans
Step-by-step explanation:
Find how many pounds of cans they have collected by subtracting 8 from both of their barrel weights:
115 - 8
= 107
98 - 8
= 90
Add these two weights together:
107 + 90
= 197
So, they collected 197 pounds of cans

Factor X squared minus 2X -80
Answer:
(x - 10)(x + 8)
Step-by-step explanation:
x² - 2x - 80
Consider the factors of the constant term (- 80) which sum to give the coefficient of the x- term (- 2)
The factors are - 10 and + 8 , since
- 10 × 8 = - 80 and - 10 + 8 = - 2 , then
x² - 2x - 80 = (x - 10)(x + 8)

There are 5 cocoa pods in a bag.
The mean weight of the 5 cocoa pods is 398 grams.
A sixth cocoa pod is put into the bag.
The mean weight of the 6 cocoa pods is 401 grams.
Work out the weight of the sixth cocoa pod that is put into the bag
Answer:
416 g
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex] , then
[tex]\frac{sum}{5}[/tex] = 398 ( multiply both sides by 5 )
sum of 5 pods = 1990 g
let x be the weight of the sixth pod , then
[tex]\frac{1990+x}{6}[/tex] = 401 ( multiply both sides by 6 )
1990 + x = 2406 ( subtract 1990 from both sides )
x = 416
That is the weight of the sixth pod is 416 g

30PTS PLEASE I NEED HELP Factor completely: 64y^3 -729z^3
Answer: (4y-9z)( 16y^2 + 36yz + 81z^2 )
=======================================================
Explanation:
We'll use the difference of cubes factoring rule
a^3 - b^3 = (a-b)(a^2+ab+b^2)
In this case,
a^3 = 64y^3 which leads to a = 4yb^3 = 729z^3 which leads to b = 9zSo,
a^3 - b^3 = (a-b)(a^2+ab+b^2)
64y^3 - 729z^3 = (4y-9z)( (4y)^2 + (4y)(9z) + (9z)^2 )
64y^3 - 729z^3 = (4y-9z)( 16y^2 + 36yz + 81z^2 )

A shipping container is in the shape of a right rectangular prism with a length of 9 feet, a width of 12 feet, and a height of 14.5 feet. The container is completely filled with contents that weigh, on average, 0.83 pounds per cubic foot. What is the weight of the contents in the container, to the nearest pound
Answer:
1,300 lb.
Step-by-step explanation:
V = 9 × 12 × 14.5 = 1566 ft³
1,566 × 0.83 = 1,299.78 ≈ 1,300 lb.
What is an equation of the line that passes through the points (-2,8) and (1, -1)?
Answer:
y = -3x + 2
Step-by-step explanation:
y2 - y1 / x2 - x1
-1 - 8 / 1 - (-2)
-9/3
= -3
y = -3x + b
-1 = -3(1) + b
-1 = -3 + b
2 = b
Need answer asap algebra 2
Answer:
A
Step-by-step explanation:
The vertex is at (2,1) The two is the important feature to start with. That means that the point is 2 away from the y axis. That goes to the left to get to the y axis.
The get the mirror image of that 2, you have to go two to the right to get to the point that mirrors (0,4). The y value has to be the same as the y intercept. So x must be 4 and y needs to be 4.
The answer is (4,4)
In case you are interested, the graph (given below) is y = 0.75 (x - 2)^2 + 1
The y intercept is 0,4 and the vertex is 2,1

Answer:
n=4
Step-by-step explanation:
3n - (2+n) = 6
Distribute the minus sign
3n -2-n = 6
Combine like terms
2n-2 =6
Add 2 to each side
2n-2+2 = 6+2
2n = 8
Divide by 2
2n/2 = 8/2

The equations y=x22−8 and y=2x−2 are graphed below. What are the solutions to the equation x22−8=2x−2?
A
x=−8 and x=−2
B
x=−6 and x=10
C
x=−4 and x=4
D
x=−2 and x=6
Answer:
x= -2 and x = 6
Step-by-step explanation:
The solutions are where the two graphs intersect
x=6, y= 10 is one point
x=-2 and y = -6 is the other point
The intersection points of both the equations are the solutions
From the graph the points are
(6,10)(-2,-6)Hence
x=-2 and x=6 are the solutions

3х - 6 = 6x - 9
Answer:
x=1
Step-by-step explanation:
3х - 6 = 6x - 9
Subtract 3x from each side
3х-3x - 6 = 6x-3x - 9
-6 = 3x-9
Add 9 to each side
-6+9 = 3x-9+9
3 =3x
Divide by 3
3/3 = 3x/3
1 =x
Answer:
3x-6=6x-9
3x-6x=-9+6
-3x=-3
-3x÷-3=-3÷-3
x=1

Step-by-step explanation:
Exterior angle thm:
40 + 3x = 5x - 10
3x - 5x = -10 - 40
-2x = -50
x = 25
5x - 10
5(25) - 10
125 - 10
115
180 - 115
65
Answer:
65
Step-by-step explanation:
The sum of the measures of the angles of a triangle equals 180°.
3x + 40 + m<1 = 180
3x + m<1 = 140
<1 and the angle measuring 5x - 10 are supplementary angles, so the sum of their measure is 180°.
m<1 + 5x - 10 = 180
Solve for m<1 and substitute in equation above.
m<1 = 190 - 5x
3x + 190 - 5x = 140
-2x = -50
x = 25
m<1 = 190 - 5x
m<1 = 190 - 5(25)
m<1 = 190 - 125
m<1 = 65

Evaluate the piecewise function at the indicated values from the domain:
In this question, we given a piece-wise function, that has different definitions depending on the domain.
Evaluate the function at x = 0.
The exercise asks for us to evaluate the function at [tex]x = 0[/tex]
We have to look at the definition, and see which definition includes [tex]x = 0[/tex]. The equal sign at [tex]x = 0[/tex] is on the second definition, that is:
[tex]f(x) = 1, 0 \leq x < 2[/tex]
