If f(x) = (3x + 8)/(2x - A) and f(0) = -2, what is the value of A?

1 answer:

5 0

Using the given info, we can determine that
$(3(0) + 8) \div (2(0) - a) = - 2$
simplify
$8 \div - a = - 2$
multiply both sides by -a
and divide each side by -2
$4 = a$
A = 4

Step-by-step explanation:

v=6t-6

integrating

s= 3t^2 -6t +k

5=3(1)^2 -6(1) +k

5-3+6=k

k=8

s(t) = 3t^2 -6t +8

-5x+7+2x-13<9 Please Explain

olganol [36]

Ok the answer is -5 less than 9 which is true lol

Anyways here’s how I got the answer

-5+7+2x-13 less than 9

Combine like terms in this case it’s -5 and 2, and the other is 7 and -13

-5+2= -3
7-13= -6

Ok now that that’s done here’s the next step

-3x-6 less than 9 solve it

-3x-6 < 9
+6< +6

-3x < 15

Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5

And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)
