Answers

Answer:

y=3x+3

Step-by-step explanation:

slope is 3 because rise over run. Rise is 3 and run is 1. 3/1 is 3. and b= y-intercept and the poiunt wehre the line intercepts the y axis is 3. so your answer is y=3x+3

Answer:

y = 3x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line

m = [tex]\frac{3-0}{0+1}[/tex] = [tex]\frac{3}{1}[/tex] = 3

the line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = 3x + 3 ← equation of line

Answer:

gradient m = - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

y = - x - 3 ← is in slope- intercept form

with gradient m = - 1

Answer:

[tex]\rm Slope = -1[/tex]

Step-by-step explanation:

Given :-

A equation of line .[tex]\rm y = -x-3[/tex]

And we need to find out the gradient of the line. The gradient of the line is the " slope " of the line. The given equation is in slope Intercept Form , which is ,

Slope intercept form :-

[tex]\rm\implies y = mx + c [/tex]

Where m is the slope of the line and c is y intercept .

On comparing it to slope Intercept Form , we have ,

[tex]\implies \rm Slope (m) = (-1)[/tex]

Hence the gradient of the line is (-1) .

Step-by-step explanation:

The coefficients of y are opposites. Adding opposites results in a sum of 0. The y-term will be eliminated by adding the equations.

If y varies directly as x and y = 24 when
x= 16, what is y when x = 50?

Answers

Answer:

[tex]y = 75[/tex]

Step-by-step explanation:

Given

[tex]y\ \alpha\ \ x[/tex]

[tex]y=24; x =16[/tex]

Required

Find y when [tex]x = 50[/tex]

We have:

[tex]y\ \alpha\ \ x[/tex]

Express as equation

[tex]y = kx[/tex]

Solve for k

[tex]k = \frac{y}{x}[/tex]

When [tex]y=24; x =16[/tex]

[tex]k = \frac{24}{16}[/tex]

[tex]k = \frac{3}{2}[/tex]

When [tex]x = 50[/tex], we have:

[tex]y = kx[/tex]

[tex]y = \frac{3}{2} * 50[/tex]

[tex]y = 75[/tex]

Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop 0.3, 0.7,0.2, 0.6,0.9 then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration). If 0.6, 0.8, 0.75 was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration). These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows. a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1 b. Add a loop around the code created in Part a that continues until counter equals 3. c. Use the variable numlterations to count how many times your loop iterates. The numerator of a fraction is 9 and the denominator is 6.
