Can someone please help me understand how to expand 8(3y-4). Please give a detailed explanation.

Answers

Answer 1

Answer:

24y - 32

Step-by-step explanation:

You take the 8 and multiply each term by in the parentheses by 8, so

8(3y - 4) becomes 8 * 3y - 8 * 4 = 24y - 32

Answer 2

Answer:

well, you can multiply them, to simplify the equation, but to expand, try adding or multiplying 2 multiples of 8, in the middle the 4 can change by adding 2+2 or 3+1. For 3y, you can do 3*y.

Answers

Answer:

x=10

y=15

Step-by-step explanation:

Since we know y in terms of x, we can use substitution and say instead of-

5x-4y=-10

5x-4(2x-5)=-10

5x-8x+20=-10

-3x=-30

x=10

Substitute x into the equation-

y=2x-5

y=2(10)-5

y=20-5=15.

Answer:

4(x + 1) and 4(x - (-1))

Step-by-step explanation:

4(-1 + 1) = 4(0) = 0

(4 (-1) + 5) = -4 +5 = -1

4(-1 - 1) = 4(-2) = -8

(5 - 4(-1)) = 5 + 4 = 9

4(-1 - (-1)) = 4(0) = 0

4 (-1 + (-1)) = 4(-2) = 8

Answers

Answer:

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Step-by-step explanation:

So first let's write a graph in vertex form with a vertex of (-5, -1)

We get

a(x+5)²-1

We now need to determine a

we know that when x= -2 y=2 which means we have

a(-2+5)²-1=2

Solve for a

a(3)²=3

9a=3

a=3/9

a=1/3

Now that we know what a is equal to we can write our equation

Veronica cut a triangular piece of cookie cake with side lengths that measure 3.6 cm, 6 cm and 4.8cm.



Did Veronica cut out a right triangle?

Answers

Answer:3.6 + 4.8 > 6

Step-by-step explanation:

The answer is YES, the triangle that is cut down by Veronica is a right triangle.

What is a triangle?

The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given information in the question,

The lengths of the sides of the triangle are given as,

Let Base, b = 3.6 cm

Perpendicular, p = 4.8 cm

Hypotenuse, h = 6 cm

Now, use the equation of Pythagoras' theorem,

h² = p² + b²

6² = 4.8² + 3.6²

36 = 23.04 + 12.96

36 = 36

It satisfies Pythagoras' theorem, which means that it is a right triangle.

An airplane flies with a constant speed of 620 miles per hour. How long will it take to
travel a distance of 310 miles? Give your answer in minutes or hours.

Answers

Answer:

30 minutes

Step-by-step explanation:

Alright lets start by laying out what the problem gives us :

A plane flies 620 mph.

It is asking how long it will take to travel 310 miles.

We need to give our answer in minutes or hours.

So lets take mph and look at the full meaning "Miles per hour"

An hour has 60 minutes in it.

So really it is saying miles per 60 minutes as well as miles per hour

So you could say the plane is traveling 620 miles every 60 minutes.

So now lets look at the number 310.

Just looking at it I can tell you that 310 looks very close to half of 620, in fact it is exactly half!

So lets divide the 620 mph by the 310 miles it is asking and we get 2! Proving that 310 is half of 620.

Alright now lets divide both the number of miles and number of minutes :

620 miles per 60 minutes

divided by 2 both miles and minutes

310 miles per 30 minutes

So this is your answer. After this you get that it would take 30 minutes to travel 310 miles in a plane going 620 miles per hour!

I hope this helps and I could help you understand it. :)
