Identify the slope of the equation 4x - 3y = - 15.

Answers

Answer:

4x

Step-by-step explanation:

Answer: 4/3

First, rewrite in slope-intercept form:

-3y=-5-4x

3y=5+4x

y=5/3+4/3x

y=4/3x+5/3

And so we can see that 4/3 is the slope of the equation.

which choice is equivalent to the expression below ^-216​

Answers

Answer:

B. 6i√6

General Formulas and Concepts:

Algebra II

Imaginary Numbers: √-1 = i

Step-by-step explanation:

Step 1: Define expression

√-216

Step 2: Simplify

Factor:                     √-1 · √216Simplify:                   i · 6√6Multiply:                   6i√6
B because when you take the square root of a negative number, it is imaginary (i). That eliminates A,C,D. When you take the square root of -216, the radical will no longer be negative since you identified it as imaginary. The greatest perfect square that you can take from 216 is 36.( 36 x 6= 216). So the square root of 36 is 6. So 6i radical 6 which is B. You can’t simplify the 6 inside the square root because it is not a perfect square. Hope this helps!

Felix graphed a system of equations that had no solution. The first equation he graphed was y = {c - 7. PLEASE HELP What was the second equation he graphed?
Answer
A y = 3x + 2
B 3y - I= -21
Cy- 2 = {(x + 1)
Dy - 3x = -7

Answers

Answer:

Choice C

Step-by-step explanation:

First when we are looking for a system of equations that has no solution we are looking for two lines that won't intersect and the only lines that would never intersect are parallel lines.

Ok so what we are looking for is an equation with the same slope but different y-intercept. A parallel line should go at the same rate like the other line but shouldn't start at the same point.

[tex]y=\frac{1}{3}x-7[/tex]

Analysing Choice A:

[tex]y=3x+2[/tex]

We just said that the slope has to be the same so this one can't be it.

Analysing Choice B:

For this one we have to put it in slope-intercept-form.

[tex]3y-x=-21\\3y=x-21\\y=\frac{1}{3}-7[/tex]

So we see that the slope is the same for this one and and the y-intercept is also the same which is NOT what we need so on tho the next one.

Analysing Choice C:

For this one we also have to put it in slope-intercept-form.

[tex]y-2=\frac{1}{3}(x+1)\\y-2=\frac{1}{3}x+1\frac{1}{3}\\y=\frac{1}{3}x-\frac{2}{3}[/tex]

We see that the slope are the same and the y-intercept are different so this is the one we are looking for.

Sorry but for the sake of time I won't analyze choice D.

=========================================================

Explanation:

Start at x = 3 on the x axis. Move up until you reach g(x), then move to the left to hit the y axis. You should arrive at y = 3.

That y value is the input to the f(x) function.

Plugging x = 3 into the f(x) function has us draw a vertical line down to f(x) and then go horizontally until we reach y = -2.

The points (-7,8) and (-11, -13) are the endpoints of a diameter on circle P. What is the length of the diameter of circle P? Round to the nearest tenth.​

Answers

The lenght of the diameter of the circle P is 6.4

To solve this particular sum we need to know the concept of Distance formula . Distance formula is nothing but calculating the lenght of a line segment which has two end points .There are various types of distance formulas which we can use to calculate various things.

The different types of distance formulas are :

Distance between 2 points in a 2D Distance between 2 points in a 3D Distance between from a point to plane Distance between two parallel lines

The distance formula is : √{(x₂-x₁)² + (y₂-y₁)²}

Using this formula we will be able to find out the lenght of diameter of the circle P where endpoints are given as (-7,8) and (-11,-13)

(x₁,y₁) = (-7,8)

(x₂,y₂) = (-11,-13)

Substituting the values of  x₁,y₁,x₂,y₂ in the formula we will get

∴ √{(-11+7)²+(-13+8)²}

= √{(-4)²+ (-5)²}

= √{16+25}

= √41

= 6.403

= 6.4 (rounded of to the nearest tenth)

Good, I can see the diagram now!

First calculate circumference of the circle.

C=2π(27)

The force required to stretch a spring by 1 m from its unstretched length is 150 N. What is the force required to stretch the spring by 3 m? 450 N

200 N

600 N

300 N

Answers

Answer:

450 N.

Step-by-step explanation:

By Hooke's law

Force = k * displacement so

150 = k * 1

So k = 150 and the equation is

F = 150 d

So when d = 3

F = 150 * 3 = 450.
