Here you have black dots at x = {0, 1, 2, 4, 4.5, 5}.

For each of these x-values, there is one and only one associated y-value. This fact tells us that the graph does represent a function.

What is the product of 2x-4 and 3x2-x+4? Write your answer in standard form. Show your work. Is the product of 2x-4 and 3x2-x+4

tatuchka [14]

Answer:

6x^3 - 14x^2 + 12x - 16. no.

Step-by-step explanation:

to solve for standard form, multiply (2x-4)(3x^2-x+4) to get the answer, this is different from (4x-2)(3x^2-x+4) because it multiplies to a completely different number, 12x^3 - 10x^2 + 18x - 8

Cammie can mow 1/2 acre in 25 minutes. If her rate is constant, Cammie says she can mow 1 1/4 acres in one hour. Is Cammie corre

Sergeu [11.5K]

Answer: No, Cammie is not correct. She can mow $1\frac{1}{5}\ acres$ in one hour (See explanation).

Step-by-step explanation:

Convert the mixed number to an impoper fraction:

1. Multiply the whole number part by the denominator of the fraction and add the product to the numerator.

2. The denominator does not change.

Then:

$1\frac{1}{4}=\frac{(1*4)+1}{4}=\frac{5}{4}$

Let be "x" the acres Cammie can mow in one hour.

You know that she can mow $\frac{1}{2}\ acre$ in 25 minutes, then you can set up the following proportion (Remember that 1 hour has 60 minutes):

$\frac{\frac{1}{2}}{25}=\frac{x}{60}$

Solving for "x", you get:

$\frac{\frac{1}{2}}{25}=\frac{x}{60}\\\\(60)(\frac{1}{50})=x\\\\x=\frac{6}{5}$

Convert from improper fraction to mixed number:

1. When you divide 6 by 5, the quotient is 1. This will be the whole number part.

2. The remainder is 1. This will be the numerator.

3. The denominator does not change.

Then:

$x=1\frac{1}{5}$

Therefore, she can mow $1\frac{1}{5}\ acres$ in one hour.
