Svetlanka [38]2 years ago
5 0

Answer: x=40

Step-by-step explanation x-0.3x=28

Add similar elements x-0.3x=0.7x

0.7x=28

Multiply both sides by 10

0.7x · 10= 28  · 10

Refine

7x=280

Using f(x) = 2x + 7 and g(x) = x - 3, find f(g(x)).
Eva8 [605]

Answer:

2x+1

Step-by-step explanation:

that's a hard question

we know that g(x)= x-3

so f(g(x))= f(x-3)

we put it in the equation :

f(x-3)= 2(x-3) +7 = 2x-6+7 = 2x +1

Multiply (6 − 7i)(3 − 6i).
Leviafan [203]

Answer:

-24 - 57i

Step-by-step explanation:

i'm assuming that this is a question about imaginary numbers and that i²= -1

we can expand the binomial by using the FOIL method (see attached)

(6 − 7i)(3 − 6i)

= (6)(3) + (6)(-6i) + (-7i)(3) + (-7i)(-6i)

=18 - 36i - 21i + 42i²   (recall that i²= -1)

= 18 - 57i + 42(-1)

= 18 - 57i - 42

= -24 - 57i
