Find the missing value for X

1 answer:

7 0

If we assume that BC is bisecting AD, and that AE is half of AD, we can set up the equation:

$2(19)=5x-7$

Then we can solve directly for x:

$38=5x-7$
$45=5x$
$x=9$

So we have then calculated x which is equal to 9.

Let f(x) = 2x − 6. solve f−1(x) when x = 2. (1 point) −5 4 −2 7

padilas [110]

Find the invers of f(x)
f(x) = 2x - 6
y = 2x - 6
y + 6 = 2x
2x = y + 6
x = (y + 6)/2
f⁻¹(x) = (x + 6)/2

Solve f⁻¹(x) for x = 2
Subtitute x with 2
f⁻¹(x) = (x + 6)/2
f⁻¹(x) = (2 + 6)/2
f⁻¹(x) = 8/2
f⁻¹(x) = 4

The answer is 4

—16t^2 + 64t + 3 Please help as soon as possible 33 points if you do it!!

aev [14]

Answer:

51t^3

Step-by-step explanation:

64+3=67

67 +(-16)=51

t^2 +t= t^3

now you just add them up but they cant be combined because one is a number and the other a variable w an exponent so we just get 51t^3
