F(x)=2x^(2)-5x-20 find f(-9)
Fed [463]

Answer:

<h2>187 </h2>

Step-by-step explanation:

f(x) = 2 {x}^{2}  - 5x - 20

To find f(-9) , substitute the value of x that's - 9 into f (x). That is for every x in f(x) replace it with - 9

We have

f( - 9) = 2 ({ - 9})^{2}  - 5( - 9) - 20 \\  = 2(81) + 45 - 20 \\  = 162 + 25 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    \\  = 187 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

How to solve 2x+4 = 6x - 10
mars1129 [50]

Answer:

Step-by-step explanation:

2x + 4 = 6x - 10

Minus 2x on both sides

4 = 4x - 10

Add 10 on both sides

14 = 4x

Divide by 4 on both sides

14/4 = x

x = 14/4

Simplify fraction

x = 7/2 or x = 3 1/2
