Systems of equations with different slopes and different y-intercepts have one solution?
Step-by-step explanation:
The systems of linear equations can have:
1. No solution: When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.
2. One solution: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system
3. Infinitely many solutions: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.
Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts never have more than one solution.

What are the two ways to determine if something is a function
Answer:
If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function. Using the vertical line test, all lines except for vertical lines are functions.

please help!!!!!!!!!!!
Answer:
x= 40
Step-by-step explanation:
The reason this is so is because a straight line's degree is always 180. And 4(40)-20=140 and 180-40=140. This is how you would work out the right side. This gives you your answer.
Answer:
40
Step-by-step explanation:
[tex]x + 4x - 20 = 180 \\ 5x = 180 + 20 \\ x = 200 \div 5 \\ x = 40[/tex]

The line perpendicular to the given line is?
Answer:
Step-by-step explanation:
Answer:
y=5/2 . *the question doesn't specify a y-intercept for the perpendicular line so just leave it as if it passes through 0.
Step-by-step explanation:
First, you isolate y to put the line in slope intercept form. Then, you take the slope and find the reciprocal(-5/2) then flip the sign giving you a slope of 5/2.

What is the vertical asymptote of the function?
O x=-10
O x=-2
O x = 0
Ox=2
Answer:d
Step-by-step explanation:
The vertical asymptote of the given function is x = 2
What is asymptotes?An asymptote of a curve is a line such that the distance between the curve and the line approaches zero as one or both of the x or y coordinates tends to infinity.
Given function is y = log(x-2)+10
The vertical asymptote for a function is a vertical line x=k and where the function becomes unbounded.
The given function x-2 =0
x =2
y = log (x-2) +10
put x=2, y = 10
Hence, the vertical asymptote is x =2

In Austin, Texas, 8 bats ate 40 grams of insects in one night. At this rate, how many grams of insects could 64 bats eat in one night?
Answer:
320 grams
Step-by-step explanation:
if 8 bats can eat 40 grams, then 64 bats can eat 320 grams because there is 8 times as much bats. so if 8x8 is 64 bats, then 40x8 is 320 grams

The volume (in cubic inches) of a shipping box is modeled by V =2x³ -19x² +39x, where x is the length (in inches). Determine the values of x for which the model makes sense.
Answer:
The values of x for which the model is 0 ≤ x ≤ 3
Step-by-step explanation:
The given function for the volume of the shipping box is given as follows;
V = 2·x³ - 19·x² + 39·x
The function will make sense when V ≥ 0, which is given as follows
When V = 0, x = 0
Which gives;
0 = 2·x³ - 19·x² + 39·x
0 = 2·x² - 19·x + 39
0 = x² - 9.5·x + 19.5
From an hint obtained by plotting the function, we have;
0 = (x - 3)·(x - 6.5)
We check for the local maximum as follows;
dV/dx = d(2·x³ - 19·x² + 39·x)/dx = 0
6·x² - 38·x + 39 = 0
x² - 19/3·x + 6.5 = 0
x = (19/3 ±√((19/3)² - 4 × 1 × 6.5))/2
∴ x = 1.288, or 5.045
At x = 1.288, we have;
V = 2·1.288³ - 19·1.288² + 39·1.288 ≈ 22.99
V ≈ 22.99 in.³
When x = 5.045, we have;
V = 2·5.045³ - 19·5.045² + 39·5.045≈ -30.023
Therefore;
V > 0 for 0 < x < 3 and V < 0 for 3 < x < 6.5
The values of x for which the model makes sense and V ≥ 0 is 0 ≤ x ≤ 3.
The values of x for which the model makes sense are 13/2 and 3
The equation that represents the volume of the box is given as:
[tex]V =2x\³ -19x\² +39x[/tex]
Factor out x from the above equation
[tex]V =x(2x^2 -19x +39)[/tex]
Expand the above equation, as follows
[tex]V =x(2x^2 -6x - 13x +39)[/tex]
Factorize the above equation
[tex]V =x(2x(x -3) - 13(x -3))[/tex]
Factor out x - 3
[tex]V =x(2x -13)(x -3)[/tex]
Equate to 0
[tex]x(2x -13)(x -3) = 0[/tex]
Solve for x
[tex]x = 0[/tex] or [tex]x = 13/2[/tex] or [tex]x = 3[/tex]
The value of x cannot be 0.
Hence, the values of x for which the model makes sense are 13/2 and 3
