Answers

Zeros can be observed graphically or solved for algebraically. A linear function can have none, one, or infinitely many zeros. If the function is a horizontal line ( slope = [latex]0[/latex]), it will have no zeros unless its equation is [latex]y=0[/latex], in which case it will have infinitely many.

Answers

Answer:

set them equal to eachother, i gotta look at my notes tho

Step-by-step explanation:

I think it's like this

3x-26=2x+24

We simpilfy the equation to the form which is simple to understand.

3x-26=2x+24

We move allterms containing X to the left and all others terms to the right

+3x-2x=+24+26

We simplfiy left and right sideof the eqution.

+1x=+50

We divide both sides of the equation by 1 to get x.

x=50

Which equation represents the linear relationship between x and y that is shown in the
table below?

Answers

Answer:

y= 5-x

Step-by-step explanation:

We notice that when we put 5 for x we get 0 which means that we must be subtracting the given x value by constant

y= 5-x makes sense, try plugging in any x value given in table and you will get its y counterpart back.

For eg, when x= -1

y= 5- (-1) = 6 (negatives add)

Answer:

The height of the square pyramid is 24 unit.

Step-by-step explanation:

Given that:

Edge of the square pyramid = 14 unit Slant height of the square pyramid = 25 unit

To Find:

The height of the square pyramid.

We know that:

In pythagoras theorem.

H² = P² + B²

Where,

H = Hypotenuse = 25 unitP = Height = Let xB = Base = 14/2 = 7 unit

Finding the height of the square pyramid:

⇒ H² = P² + B²

⇒ (25)² = x² + (7)²

⇒ 625 = x² + 49

⇒ x² = 625 - 49

⇒ x² = 576

⇒ x = √576

⇒ x = 24

Hence,

The height of the square pyramid = 24 unit

What is the distance between two points(0,0)(-3,5)

Answers

Step-by-step explanation:

Think of it like a right triangle. Do you have a graph handy?

Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.

Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?

All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.

9+25=34

√34 is our hypotenuse & distance between the points

There is a bag of tiles where 8 are red, 5 are blue, 4 are orange, and 3 are green. If one is picked at random, replaced, and another marble is picked, what is the probability that they are both orange? in a percent or fraction

Answers

Answer:

There would be 1/25 chance (4%).

Step-by-step explanation:

So there's 4 orange marbles and there's 20 total marbles since:

8 Red + 5 Blue + 4 Orange + 3 Green

With this, the chance of drawing an orange marble is 4/20, or 1/5. Because the marble is replaced back after being picked, the same chance would occur for the second picking.

To combine these chances, multiply them together for the answer.

1/5 * 1/5 = 1/25 (4%)

8+5+4+3=20
(1/20)*(1/20)=1/40
