please help me :Tom ate four more pieces of fruit than Janet. Sylvia ate twice as many pieces of fruit as Tom. If x represents the number of pieces of fruit that Janet ate, write an expression to represent the amount of fruit that Sylvia ate.

Answers

J=X
T= X+4
S= 2(X+4). So s is sylvia

Final answer:

If x represents the number of pieces of fruit Janet ate, then Sylvia ate 2 * (x+4) pieces of fruit based on the given question.

Explanation:

The question requires an algebraic expression to show how many pieces of fruit Sylvia ate. According to the question, Tom ate four more pieces of fruit than Janet. If x is the number of fruits Janet ate, then we can represent the number of fruits Tom ate as x + 4.

Next, the question states that Sylvia ate twice as many pieces of fruit as Tom. So, we can represent the number of pieces of fruit Sylvia ate as 2 * (x+4). Hence, this is the expression that represents the amount of fruit that Sylvia ate.

3(4) _ 2(2) = 8
the graph is so easy, please try!!

Answer:

Option A is correct.

x =4 , y = 2

Explanation:

Given the system of equation:

$2x+6y = 20$ ......[1]

$3x-2y = 8$ .....[2]

Multiply equation [2] by 3 both sides we get;

$3 \cdot (3x-2y) = 3 \cdot 8$

Using distributive property: $a\cdot (b+c) = a\cdot b+ a\cdot c$

$9x - 6y = 24$ .....[3]

Add equation [1] and [3], to get eliminate y we get;

$2x+6y+9x-6y= 20+24$

Combine like terms we have;

$11x = 44$

Divide both sides by 11 we get;

$x = 4$

Substitute the value of x =4 in [1] we get;

2(4) + 6y = 20

8 + 6y = 20

Subtract 8 from both sides we have;

6y = 12

Divide both sides by 6 we have;

y = 2

Therefore, the values of x and y are; 4 and 2.

If an equation of the linear function in the figure above is y=mx=b, than m=

Answers

The answer to the math question you have presented above would be 0. If an equation of the linear function in the figure above is y=mx=b, then m is equal to 0. Based on the coordinates you gave me, the logical answer would be 0 because both y and x are zeros. This means that there is no slope.

If an equation of the linear function in the figure above is y = mx + b, than m = -2

Further explanation

Solving linear equation mean calculating the unknown variable from the equation.

Let the linear equation : y = mx + c

If we draw the above equation on Cartesian Coordinates , it will be a straight line with :

m → gradient of the line

( 0 , c ) → y - intercept

Gradient of the line could also be calculated from two arbitrary points on line ( x₁ , y₁ ) and ( x₂ , y₂ ) with the formula :

$\large {m = (y_2 - y_1)/(x_2 - x_1)$

If point ( x₁ , y₁ ) is on the line with gradient m , the equation of the line will be :

$y - y_1 = m ( x - x_1 )$

Let us tackle the problem.

Since the figure is unknown, I will assume it is as shown in the attachment.

First, let us find the equation of solid line passing through points (0 , 2) and (1, 0) by using this formula :

$(y - y_1)/(y_2 - y_1) = (x - x_1)/(x_2 - x_1)$

$(y - 2)/(0 - 2) = (x - 0)/(1 - 0)$

$(y - 2)/(- 2) = (x)/(1)$

$1 (y - 2) = -2 (x)$

$y - 2 = -2x$

$\large {\boxed {y = -2x + 2} }$

From above equation , it can be concluded that if y = -2x + 2 , then m = -2 and b = 2

If the product of 6 and an integer (n) increased by 13, the result is -14 what is the value of n?

Answers

-33, I found the answer by adding 6 with 13...
6+13=19
then I added 19+14=33
Then you know that it has to be a negative so...
-33 is the answer
Hope it helped :)

Final answer:

The value of the integer 'n' in the given equation 6n + 13 = -14 is -4.5

Explanation:

The problem seeks to determine an integer 'n' such that the product of 6 and 'n,' increased by 13, equals -14. This can be represented by the equation 6n + 13 = -14. To solve for 'n,' we begin by isolating it. First, we subtract 13 from both sides of the equation, resulting in 6n = -27. Then, we divide both sides by 6 to determine 'n.' Consequently, the value of 'n' is found to be -27/6, which simplifies to -4.5. However, it's worth noting that 'n' must be an integer, and -4.5 is not an integer. Therefore, there may be an issue with the problem statement or solution.

The vertical height v, in feet, of a snowboarder jumping off of an overhang can be modeled by the function h(t)=15-10t-16t^2, where 15 is the initial height (in feet) of the overhang, -10 is the initial vertical velocity (in feet per second), and t is the time (in seconds). How long does it take the snowboarder to land after jumping off the overhang?"

Answers

Step-by-step explanation:

It is given that, the vertical height v, in feet, of a snowboarder jumping off of an overhang can be modeled by the function as :

$h(t)=15-10t-16t^2$

Where

15 is the initial height of the overhang

-10 is the initial vertical velocity

t is in second

We need to find the time taken by the snowboarder to land after jumping off the overhang. At this condition,

h(t) = 0

So, $15-10t-16t^2=0$

On solving above equation using online calculator, we get the value of t = 0.705 seconds. So, the time taken by the snowboarder to land after jumping off the overhang is 0.705 seconds.

I don't know for sure, but I think there might be an error in the way you copied your function. In all of my dealings with these types of problems, I have learned the formula to be h(t) = 15 + 10t - 16t^2. Notice the plus in front of the "10t". This is due to the fact that if he pushes off of the overhang he would have an upward force of 10 feet per second as soon as his feet left the ground. The only thing pulling him back to Earth is gravity, modeled by the "-16t^2". This is derived from a bit of slightly advanced physics involving the gravitational constant, but let's work under my formula for a second...

Either way, we will wind up using the Quadratic Formula (or possibly factoring if the numbers are easy enough to work with). So let's start.

h(t)= 15 +10t - 16t^2

In order to use the QF or factoring I will need to make h(t)=0. Simply done by:

0= 15 +10t -16t^2

Looking at the numbers, I'd prefer to use the QF so here it is:

$x= \frac{-b + or - \sqrt{b^(2)-4ac } }{2a}$

I know that my answer will need to be positive since you can't have a negative value when dealing with time, so I will eliminate the positive sign from the "+or-" part leaving me with:

$x= \frac{-b -\sqrt{b^(2)-4ac } }{2a}$

And I know that a= -16, b= 10, and c=15. So all that's left to do is substitute and solve.

$x= \frac{-10 -\sqrt{-16^(2)-4*-16*15 } }{2*-16}$

There's a decent amount of math that would be difficult and sloppy for me to do over the computer, but all you need to do is solve the rest of the equation and you would get your answer.

Exact answer: $(5-4 √(15) )/(8)$ or rounded answer: ≈1.31 seconds.

Hope this helps!
