Are 4/3 and 3/4 Parrallel lines?
Answer:
No
Step-by-step explanation:
if you mean that:
[tex]m_{1} = \frac{4}{3}[/tex]
[tex]m_{2} = \frac{3}{4}[/tex]
And ask if m1 is parallel to m2. Then no.
Two lines are only parallel if their slopes are the same.
And since 4/3 is not equal to 3/4. Then the lines are not parallel.

help with math pls thanks so much
Answer:
2/5
Step-by-step explanation:
The y-intercept is the number being added or subtracted in the equation when you have y = mx + b. For example, in the equation y = 9x - 4, the y-intercept is -4, and in the equation y = 3x + 7, the y-intercept is 7. The number being added in this case is 2/5, so it is the y-intercept.

The local approximation to the function g at x=1/2 is y=4x+1. What is the value of g(1/2) + g'(1/2)?
Given :
The local approximation to the function g at x = 1/2 is y = 4x+1.
To Find :
The value of g(1/2) + g'(1/2).
Solution :
It is given that at g( y ) = 3x + 1 , at x = 1/2.
Differentiating g( y ) w.r.t x ,we get :
g( y )' = 3
So, g( y ) + g( y' ) = 3/2 + 1 + 3
g( y ) + g( y' ) = 11/2
Hence, this is the required solution.

b is 125
Step-by-step explanation:
Here is a right-angled triangle.
y cm
8.2 cm
12.3 cm
Work out the value of y.
Give your answer correct to 1 decimal place.
Answer:
9.1
Step-by-step explanation:
Let,
hypotenuse = 12.3 cm
perpendicular = 8.2 cm
base = y cm
(hypotenuse)^2 = (perpendicular)^2 + (base)^2
(12.3)^2 = (8.2)^2 + y^2
151.29 = 67.24 + y^2
151.29 - 67.24 = y^2
.: y^2 = 84.05
y = √84.05
y = 9.1

Graph a sine function whose amplitude is 4, period is π , midline is y=−3, and y-intercept is (0, −3). The graph is not a reflection of the parent function over the x-axis.
Use the sine tool to graph the function.
The first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
Answer:
y=4sin(2x) - 3
Step-by-step explanation:
Recall the form of a sinusoidal function is Asin(Bx + C) + D, where A is the amplitude, B is the frequency (could also be viewed as the period), C is the horizontal (phase) shift, and D is the vertical shift. Also, recall sin(x) has a period of 2π.
You start with the parent function (sin(x)).
Then, knowing the amplitude is 4: 4sin(Bx + C) + D
Then, knowing the period of the regular sine function is 2π, to get to a period of π, divide by 2 (the period of the curve changes by a factor of 1/2), so your B coefficient is 2: 4sin(2x + C) + D
There is no phase shift, so omit C: 4sin(2x) + D
Since the midline is y = -3, that is your vertical shift (D): 4sin(2x) - 3
Graph of y = 4sin(2x) - 3 is below:
Answer: The graph is shown below.
Explanation:
The midline is y = -3 and the y intercept is (0,-3). This is point A in the diagram below.
The period is pi units, which means that going from midline to peak (or valley) is 1/4 of this distance. So it's pi*(1/4) = pi/4 = 0.79 units approximately from x = 0 to x = 0.79; which is the x coordinate of point B. Point B is one of the infinitely many maximum points. Notice that the vertical distance from A to B is 4 units, which is the amplitude.
Extra info:
The equation of this sine curve is y = 4sin(2x)-3

y = x + 8
4x – 2y = -12
Answer:
x = 14
y = 22
Step-by-step explanation:
y = x + 8
4x - 2y = -12
Solve
_____________
Since we see that the first equation has y alone, we can substitute it into the values of y in the second equation.
4x - 2(x + 8) = -12
Distribute :
4x - (2(x) + 2(8)) = -12
4x - 2x +16 = -12
Combine like terms :
2x + 16 = -12
Subtract 16 from both sides :
2x = -28
Divide 2 from both sides to get x alone :
x = 14
Now that we know what x is, substitute it in the first equation to get y :
y = (14) + 8
y = 22
Answer:
(2 , 10) or x = 2 & y = 10
Step-by-step explanation:
y = x + 8
4x – 2y = -12
1. Substitute x + 8 in for the y in the other equation.
2. Solve for x
3. Take the solution for x and substitute the number in for the x in y = x + 8.
4. Solve for y.
5. Your answer is the result.
4x - 2(x + 8) = -12 Distributive Property
4x - 2x - 16 = -12 Combine like terms
2x - 16 = -12 Isolate the x, so start by moving -16
+ 16 +16
2x + 0 = 4 Delete the 0. It is a place holder you don't need
2x = 4 Isolate the x by dividing both terms by 2.
2 2
x = 2
y = x + 8 Substitute the 2 in for x and solve the one step equation.
y = 2 + 8
y = 10

Step-by-step explanation:
two friends have a conversation mario tells roberto "the money i have is twice that you have" roberto answer "if you give me 6 dollars will we both have the same amount" how much money have each of them?
Answer:
Before anyone gives anyone money, Mario has 24 dollars and Roberto has 12 dollars. After they give each other money, both of them have 18 dollars.
Step-by-step explanation:
Mario has twice as much as Roberto, BUT if Mario gives Roberto 6 dollars, then they have the same amount.
M = 2R
M - 6 = R + 6
To isolate M, you need to add 6 on both sides.
M - 6 + 6 = R + 6 + 6
M = R + 12
M = 2R
Substitute M for the value above that we found.
R + 12 = 2R
Now we subtract R on both sides, so that only one side has the variable R.
R - R + 12 = 2R - R
12 = R
M = 2R
Substitute for the value of R.
M = 2 x 12
M = 24
can someone tell me how to solve 8th grade slope! I'll put you as brainliest!!
Answer:
Step-by-step explanation:
Well, the formula to find slope is y2-y1 / x2-x1
Here's an example:
(2,12) (4,24)
12-24 / 2-4 =
-12/-2 or 6
You would use:
(y=mx+b) to find an entire equation, including the y intercept
Let me know if this helps, and if it doesn't, I hope I'll be able to explain it better.
