Answer:   x = -1/2

Step-by-step explanation:

1/2 x - 3/10  =  5/2 x + 7/10

-1/2 x on both sides

-3/10 = 4/2 x +7/10

subtract 7/10 from both sides

-1 = 4/2x

simplify

2x = -1

divide 2 on both sides

x = -1/2

If you where born in 1620 and died in 1730 how old where u before u died?<br><br><br> pls help ;-;
Tema [17]

To make it simple, just subtract the age that you died to the age that you were born.

1730 - 1620 = 110

Which means that you would die at the age of 110 if you were born at 1620 and died on 1730.

Find the slope of the tangent line to the graph of f at the given point. 
jarptica [38.1K]

slope = 13

the slope of the tangent is f'( 4)

given f(x) = x² + 5x , then f'(x) = 2x + 5

and f'(4) = ( 2 × 4 ) + 5 = 13
