Answer:

f(1) = 2

Step-by-step explanation:

<u>Step 1:  Identify the function</u>

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

<u>Step 2:  Simplify the function</u>

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

<u>Step 3:  Set x to 1 in the function</u>

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

f(1) = 3*1 - 1 - 1

f(1) = 3 - 1 - 1

f(1) = 2

Answer:  f(1) = 2

What is the value of x if:<br> -0.1x + 3/10 = 4/10<br> Solve as linear equation.<br> NEED HELP ASAP
Anika [276]

Answer:

x= -1

Step-by-step explanation:

Solving through linear equation,

-0.1x + 3/10= 4/10

Bring 3/10 to the other side making it minus

-0.1x = 4/10 - 3/10

-0.1x = (4-3)/10

-0.1x= 1/10

Bring -0.1 to the other side n divide

x= 1/10 ÷ -0.1

( Note that -0.1 is the same as -1/10)

x = 1/10 ÷ -1/10

= 1/10*-10/1

= -10/10

= -1

1. (08.01 MC)<br> The graph shows two lines. A and B
Ivahew [28]

Answer:

Part A:

A pair of linear equations can only have one solution or infinitely many solutions. In this case, there would only be one solution as they intersection at only one point.

Part B:

The solution would be (3, 4) because it is the point of intersection between the two linear lines.
