How do I solve 5x - 4 = -19

ira [324]

Undo what has been done to the variable. That means to do the opposite done to the variable.
5x-4=-19
+4=+4
5x=-15
5 is being multiplied to the variable so you divide it from both sides.
x=-3

Picture with question help plz

kirill [66]

Let $a_{1}$ = -9, $a_{2}$ = -12 and so on.

-15 = -9 + (-6)

-15 = -9 + 2(-3)

Let -3 be the common difference, or <em>d</em>.

$a_{n}$ = -9 + n(-3)

= -9 - 3n

Answer:

m = 12

Step-by-step explanation:

For f(x) = 2x² you want to find the slope m using ...

m = (f(x+h) -f(x))/h

at x=3.

Filling in the function definition and its arguments, we have ...

m = (2(x+h)² -2x²)/h = (2x² +4hx +2h² -2x²)/h = 4x +2h

The value of this as h goes to zero is ...

m = 4x

At x=3, the slope is ...

m = 4·3 = 12

_____

The attached graph shows a numerical estimate of the slope (f'(3)=12) and the line with that slope through the point P(3, 18). The line certainly appears to be tangent to the curve at that point.
