Drag each tile to the correct box.
serg [7]

Answer:

The functions ordered from least to greatest y-intercept are

1) h(x) -----> y-intercept -1

2) g(x) ----> y-intercept 1

3) f(x) ----> y-intercept 2

Step-by-step explanation:

we know that

The y-intercept (or initial value) is the value of y when the value of x is equal to zero

Part 1) Find the y-intercept of g(x)

Remember that the initial value of the fuction is equal to the y-intercept

a=1 -----> is the initial value

therefore

The y-intercept of g(x) is 1

Part 2) Find the y-intercept of f(x)

Observing the table

For x=0

f(x)=2

therefore

The y-intercept of f(x) is 2

Part 3) Find the y-intercept of h(x)

Observing the graph

For x=0

h(x)=-1

therefore

The y-intercept of h(x) is -1

Help please! I’m struggling ah sksjkdkkdkd <br> -Alyssa
Maurinko [17]

He would weight 3.745 kg. Dividing it by 1,000 which is what a kg is more to a gram, 1,000 g = 1 kg. If the problem looked like 3,745. then move the dot over by how many zero's there is in 1,000, which is 3. 3.745. And sorry, but I am not sure about your other problem. But if I were to guess, I would say 34 units.

Trench Warfare<br> Define in own words
Andrei [34K]

Answer:

Trench warfare was a technique used to fight in World War 1. As they could hide/defend there. Get supplie there. They could even have medical areas there, but the problem was a stalemate as that was such a thing that no one attacks and they stay without moving on in the battle.

Haley is comparing the cost of a fresh lobster dinner at two different restaurants. The first restaurant charges $29 for the mea
Svetllana [295]

First restaurant price: 29 + 6l = x

x = final cost

l = kilo of lobster

Second restaurant price: 41 + 3l = x

We want them to be the same price, so: 29 + 6l = 41 + 3l

Subtract 3l from each side

29 + 3l = 41

Subtract 29 from both sides

3l = 12

Divide both sides by 3

l = 4

So, if she buys 4 kilograms of lobster from either place, it will cost the same.

It would cost $53.
