If f(x)=2x^2-3x what is the value of f(5)

To find f(5), all you need to do is substitute 5 in for x in f(x). This allows us to find our answer:

f(5) = 2(5)^2 - 3(5)

f(5) = 50 - 15

f(5) = 35


The answer is f(5) = 35.

The answer is 35

Here's how I got my answer:

Step 1: Replace all x's with 5. Leaving us with 2(5)^2-3(5)

Step 2: Solve 5^2, which is 25. That leaves us with 2(25)-3(5)

Step 3: Solve 2(25), which is 50. That leaves us with 50-3(5)

Step 4: Solve 3(5), which is 15. That leaves us with 50-15

Step 5: Simplify 50-15 to get your answer, 35.

Select the correct answer. Which relationship does the graph represent?
vladimir2022 [97]

Answer:

D

Step-by-step explanation:

perimeter of square = 4 length of its sides

x represents the side lengths

y represents the perimeter of the a square

y = ax + b

a = slope = y2-y1 / x2 -x1

= 8-4 / 2-1 = 4

y = 4x + b

from any point (1,4 )

4 = 4 .(1) + b

b= 0

y = 4x

Find all real numbers X such that 18x-9>9 or 2x-4>-10
mixer [17]
So what we are going to do is the next thing:Consider 18x-9>9 1. add 9 to both sides 2. divide both sides by the coefficient of x (that is 18 in this case) Now Consider 2x-4>-10 1. Then add 4 to both sides 2. divide both sides by the coefficient of x (that is 2 in this case) The final solution would be x < 1 Hope this can fit what you are looking for
