Which equation has infinitely many solutions?

1 answer:

3 0

1-2x=-(2x-1) is the equation that has infinitely many solutions because -(2x-1) can be simplified using the distributive property as -2x+1 which is the same as 1-2x but just the order switched.

A jellyfish travels 3/5 mile in 1/6 hour and a walrus travels 5/6 mile in 3/10 hour.

Answer:

The jellyfish travels faster than the walrus

Step-by-step explanation:

Given data

A jellyfish travels 3/5 mile in 1/6 hour

Distance= 3/5 mile

time= 1/6 hour

speed= distance/time

speed= 3/5/1/6

speed= 3/5*6/1

speed= 18 mile per hour

a walrus travels 5/6 mile in 3/10 hour.

Distance= 5/6 mile

time= 3/10 hour.

speed= distance/time

speed= 5/6/3/10

speed= 5/6*10/3

speed= 50/18 mile per hour

A graph is a straight line through the point (0, 5). Can the graph represent a proportional relationship? Explain.

Snezhnost [94]

Answer:

The graph cannot represent a proportional relationship

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and <u><em>the line passes through the origin</em></u> (0,0)

That means----> The x-intercept and the y-intercept of the line must to be the origin (0,0)

If the given line passes through the point (0,5), then the line not passes through the origin

therefore

The graph cannot represent a proportional relationship

Answer:

Step-by-step explanation:

Given

log_3x = 3/2 can be rewritten as

3^1.5 = x

You calculator will give you the simplest answer to this. Look around for a key that looks like ^ or y^x or x^y.

Then you put the base (3) into your calculator and press your y^x key and put in 1.5

Answer:

x = 5.1962
