Answer:

3

Step-by-step explanation:

f(x) = 2x^2 + 1

f(-1) means that wherever you see an x on the right hand side, you substitute -1.

f(-1) = 2(-1)^2 + 1 = 2 + 1 = 3

9. What is 74 as a mixed number? ​
Fittoniya [83]

Answer:

Here we will show you how to convert the improper fraction 74/9 to a mixed number (aka mixed fraction). We start by setting up the fraction below.

   74  

   9  

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 74 by 9 and keep only what is to the left of the decimal point:

74 / 9 = 8.2222 = 8

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

74 - (9 x 8) = 2

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 74/9 as a mixed number is:

8

   2

I have to solve this proportion x+2/4=8/4
Eva8 [605]

Answer:


Step-by-step explanation:

Isolate the x. Note the equal sign, what you do to one side, you do to the other.

Subtract 2/4 from both sides

x + 2/4 (-2/4) = 8/4 (-2/4)j

x = 8/4 - 2/4

Simplify

x = (8 - 2)/4

x = 6/4

Simplify. Change the improper fraction into mixed fraction

x = 6/4 = (4/4 + 2/4) = 1 2/4

1 2/4 simplified = 1 1/2

1 1/2 is your answer
