For the function f(x)=|4x−2|+10, evaluate f(−3).

Orlov [11]

Answer:

$f(-3)=24$

Step-by-step explanation:

So we have the function:

$f(x)=|4x-2|+10$

To find f(-3), substitute -3 for x:

$f(-3)=|4(-3)-2|+10$

Multiply within the absolute value:

$f(-3)=|-12-2|+10$

Subtract:

$f(-3)=|-14|+10$

The absolute value of -14 is 14. Thus:

$f(-3)=14+10$

Add:

$f(-3)=24$

And we're done!

Solve each system of equations by substitution: X + Y = 75 10x + Y = 48

Nimfa-mama [501]

Answer:

X= -3;

Y=78

Step-by-step explanation:

A: X+Y=75

B: 10X+Y=48

B-A: (10X+Y)-(X+Y)=48-75

10X+Y-X-Y= - 27

9X=-27

X= -3;

Now

A is : -3+Y=75

Y=75+3=78
