Mathematics

Eva8 [605]3 years ago
6 0

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

Solve for x:<br><br> x = <br> Answers: 22.5 30 45
AVprozaik [17]
Answer: 22.5 degrees

Step-by-Step Explanation:

As we can see, we are given a line, which is a straight angle. Hence, it will be of 180 degrees.

=> All the angles sum up to 180.

Therefore,
=> 3x + x + 90 = 180
= 4x + 90 = 180
= 4x = 180 - 90 = 90
=> x = 90/4 = 22.5

Therefore, x = 22.5 degrees

Verification:

=> 3x + x + 90 = 180
= 3(22.5) + 22.5 + 90 = 180
= 67.5 + 22.5 + 90 = 180
= 90 + 90 = 180
=> 180 = 180
=> LHS = RHS

What number is represented by point P?
likoan [24]

Answer:

0.0057

Step-by-step explanation:

  • Narrow it down.
  • The point P is between 5 * 10^-3 and and 6*10^-3
  • When you go to the bottom line, P is on the 7th division from the left.
  • Going from left to right increases P
  • P is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.
  • One of the answers is 5.7 * 10^-3
  • The other answer is .0057
  • I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.
  • If it is not correct, then 5.7 * 10^-3 is the answer.
