Write equivalent expressions of 18m+42n​
serious [3.7K]

Answer:

See explanation

Step-by-step explanation:

Given:

18m + 42n

These two variables are not the same, so we can't add the two terms. However, we can factor out a number out of this expression.

The GCF of 18 and 42 is 6.

We can draw 6 out of this expression to get 6(3m + 7n).

This is an equivalent expression.

We can also draw 2 out to get 2(9m + 21n).

We can also draw 3 out to get 3(6m + 14n).

We can also draw 1/2 out to get (1/2)(36m + 84n).

There are endless possibilities, but these are a few. You get the idea!

The graph shows the level of ibuprofen, y units, in a patient’s bloodstream x hours after the ibuprofen was taken. Select the co
ElenaW [278]

The graph is missing, so i have attached it.

Answer:

From 0 hours to 2 hours.

Step-by-step explanation:

From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.

Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.

After that point, the curve begins to to go down. Since we are concerned with increase, we will make do with the first statement.

Thus, we can say the period at which the level of ibuprofen increased was from 0 hours to 2 hours.

Write the equation of the parabola that has the vertex at point (1,3) and passes through the point (−1,5).
Andrei [34K]

Answer:

y = \frac{1}{2} x² - x + \frac{7}{2}

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (1, 3 ), thus

y = a(x - 1)² + 3

To find a substitute (- 1, 5) into the equation

5 = a(- 1 - 1)² + 3 ( subtract 3 from both sides )

2 = 4a ( divide both sides by 4 )

a = \frac{1}{2} , thus

y = \frac{1}{2} (x - 1)² + 3 ← expand factor using FOIL

y = \frac{1}{2} (x² - 2x + 1) + 3 ← distribute parenthesis

  = \frac{1}{2} x² - x + \frac{1}{2} + 3

  = \frac{1}{2} x² - x + \frac{7}{2}
