-2x + 7 < 23 which graph ?

Mathematics
1 answer:
Ilya [14]3 years ago
6 0

Answer:

The red one/bottom one. x>-8

Step-by-step explanation:

Subtract 7 giving you 16. Divide by negative 2 which gives you -8, but since your dividing by a negative you have to flip the sign. The Answer is x>-8. The Sign points which way you have to shade, the answer is which point you shade at, and the opened circle means that it is NOT equal to that answer but it is bigger. Closed circle if it is equal to. ;)

The question is in the picture:
rosijanka [135]

Answer:

  b) The measure of angle B is 117°.

Step-by-step explanation:

Angles A and C are vertical angles, so are congruent. Angles C and 27° total 90°, so ...

  ∠C = 90° -27° = 63° . . . . . not 53°

The measure of angle B is the supplement of angle A or C, so is ...

  ∠B = 180° -∠C = 180° -63°

  ∠B = 117°

Only choice B is correct.
