Answer:

1/2

Step-by-step explanation:

1. multiple 3

3b + 1 = 4b - 1

2. subtract 3b from both sides

1 = 1b - 1

3. add 1 from both sides

2 = 1b

4. divide 1 from both sides

Which statements are correct interpretations of this graph?
kupik [55]

Answer:

B. 3 pages are edited every five minutes

D. 6/10 of a page is edited per minute

Step by step:

Three pages are done at an interval of five minutes.

Six tenths of a page is done every minute

0.6 * 5 = 3 per five minutes

The other statements are false.

12/3 = 4, four done every minute, really?

5 pages are edited every three minutes.

This would disprove statement B.

And does not align with the graph.

Hope this helps.

Given the function f(x) = −3x3 + 9x2 − 2x + 3, what part of the function indicates that the left end starts at the top of the gr
shutvik [7]

Answer: The correct option is, The coefficient of the first term.

Step-by-step explanation:

The given function is,

f(x)=-3x^3+9x^2-2x+3

End behavior of the polynomial function : It is defined as the graph of f(x) as x approaches +\infty and -\infty.

The end behavior of the graph depends on the leading coefficient and degree of the polynomial.

As, the degree of the polynomial is '3'. So, the leading coefficient will determine the structure of the graph.

Therefore, the coefficient of the first term will indicate that the left end starts at the top of the graph.

The graph is also shown below.

Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilo
dedylja [7]

Answer:

xy=wz

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = y km/min

Time taken up the hill = x minutes

Speed of Wilmer down the hill = z  km/min

Time taken up the hill = w minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

Distance = Speed \times Time

Distance up the hill = y\times x =xy\ kilometers

Distance down the hill = z\times w =wz\ kilometers

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

xy=wz
