Graph: y = 3x - 5
Plz help
Answer:
The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!
hope this helped!
Answer:
Step-by-step explanation:
y=3x-5 is a line
pick any 2 points for example
(x=0, y=(3*0)-5=-5) so one point is (0,-5)
(x=2, y=(3*2)-5= 1) so another point is (2, 1)
draw a line trough points (0, -5) and (2, 1)
It took a submarine 30 seconds to sink 225 feet, moving at a constant speed. The captain wants to know the submarine's speed.
What is a submarine's speed in feet per second?
Answer:
Speed per second= 7.5 feet per second
Step-by-step explanation:
Giving the following information:
We have a distance (225 feet), and a time (30 seconds). Also, we know that the speed was constant.
All we have to do is divide the distance by the time and determine the speed per second:
Speed per second= distance / time
Speed per second= 225 / 30
Speed per second= 7.5 feet per second

the larger number is 3 less then 4 times the smaller number. the sum of the numbers is 17 find the smaller and larger number
Answer:
Smaller number = 4
Larger number = 13
Step-by-step explanation:
Smaller number = x
Larger number = 4x - 3
Sum of the numbers = 17
x + 4x -3 = 17 {Combine like terms}
5x - 3 = 17 {add 3 to boht sides}
5x = 17 + 3
5x = 20 {Divide both sides by 5}
x = 20/5
x = 4
Larger number = 4x - 3
= 4*4 -3
= 16 - 3
= 13

Which equation represents a line which is parallel to x = 0?
1. X=1/5y
2. Y=x
3. Y=-7
4. X=-8
The equation represents a line that is parallel to x = 0 will be y = x.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given that there is an equation that represents a line that is parallel to x = 0. The equation will be calculated as below:-
y = mx + c
y = x slope will be equal to 1.
Therefore, the equation represents a line that is parallel to x = 0 will be y = x.

A square has an area of 100 square meters what is the perimeter of the square
Answer:
40?
Step-by-step explanation:
10 x 10= 100
but this is perimeter so it would be 10 by 4 sides
10x4=40
Answer:
40
Step-by-step explanation:
A square has equal sides, area is length times height, meaning the square root of 100 is one side of the square. [tex]\sqrt{100}[/tex] = 10, because 10(10) = 100
Now one side is 10 meters, a square has 4 equals sides so:
10(4) = 40
Or u can do it the long way, 10 + 10 + 10 + 10 = 40

Systems of equations with different slopes and different y-intercepts have more than one solution. (5 points)
Always
Sometimes
Never
Answer:
The correct answer would be never
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.

Vertical asymptote at x= -6 and 6. The zero is 0
Step-by-step explanation:
20 blue fish and 50 total
9514 1404 393
Answer:
asymptotes: x=±6, y=0; zero: x=020 blue fishStep-by-step explanation:
1. The vertical asymptotes are where the denominator is zero.
x² -36 = 0
(x -6)(x +6) = 0 ⇒ x = 6 or x = -6 . . . vertical asymptotes
The horizontal asymptote is the function value when x is large. Since the numerator is lower degree than the denominator, the ratio becomes near 0 as x gets large. The horizontal asymptote is y = 0.
The function value is zero when the numerator is zero:
6x = 0 ⇒ x = 0 . . . . the zero of the function
A function graph is attached, with vertical asymptotes and zero shown.
__
2. You can work this problem by considering the ratios.
If 60% of fish are red, then 40% are blue. The difference in numbers is 60% -40% = 20% of the total number of fish. That difference is 10 fish.
The number of blue fish is 40% of the total, which is 2×20% = 2×10 fish.
There are 20 blue fish.

Find the equation of the line
passing through the points (3,1) and (7,-7)
Answer:
y = -2x+7
Step-by-step explanation:
equation of line formula:
[tex]y = mx + c[/tex]
m = slope, c = y-intercept
1) find the slope using the given coordinates
slope formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
i) (3,1)
x1=3
y1=1
ii) (7,-7)
x2=7
y2=-7
substitute the values into the formula
[tex]m = \frac{ - 7 - 1}{7 - 3} [/tex]
[tex]m = \frac{ - 8}{4} [/tex]
[tex]m = - 2[/tex]
so now half of the equation is complete as we have the the value of m. substitute the value of m into the slope formula.
[tex]y = - 2x + c[/tex]
2) find the value of c
to find the value of c, we must substitute either coordinate into the half equation. so, i choose the coordinate (3,1). if you substitute the coordinate (7,-7) , you will get the same value of c.
(3,1)
x = 3
y = 1
[tex]y = - 2x + c[/tex]
[tex]1 = - 2(3) + c[/tex]
[tex]1 = - 6 + c[/tex]
[tex]1 + 6 = c[/tex]
[tex]c = 7[/tex]
substitute the value of c into the half equation and that is your straight line equation
[tex]y = - 2x + 7[/tex]
