Please help asap needed kinda quick

x = -2,   x = -8

Step-by-step explanation:

| x+5| =3

When we solve absolute values, we need to separate it into two equations, one positive and one negative

x+5 =3           x+5 = -3

Subtract 5 from each side

x+5-5 = 3-5       x+5-5 = -3-5

x = -2                 x = -8

Since the equation has absolute value, that means that answer can be either positive or negative.

Split the original equation into two equations.

x + 5 = 3 and x + 5 = -3

Now, solve for x in both equations.

Solution #1:

x + 5 = 3

~Subtract 5 to both sides

x + 5 - 5 = 3 - 5

~Simplify

x = -2

Solution #2:

x + 5 = -3

~Subtract 5 to both sides

x + 5 - 5 = -3 - 5

~Simplify

x = -8

Best of Luck!

Step-by-step explanation:

f(4) = 42 + 5 =21, f(-10) = (-10)2 +5 = 105 or alternatively f: x → x2 + 5.

The phrase "y is a function of x" means that the value of y depends upon the value of x, so:

y can be written in terms of x (e.g. y = 3x ).

If f(x) = 3x, and y is a function of x (i.e. y = f(x) ), then the value of y when x is 4 is f(4), which is found by replacing x"s by 4"s .

If f(x) = 3x + 4, find f(5) and f(x + 1).

f(5) = 3(5) + 4 = 19

f(x + 1) = 3(x + 1) + 4 = 3x + 7
