so if 4 hours of math is 186, one hour is 46.5, therefore when you write a liner equation, you start with y=46.5x and then multiply 19 by 46.5
Answer:
B
Step-by-step explanation:
Given
11 - 4x = (3x - 2)² + 1 ← expand the squared factor using FOIL
11 - 4x = 9x² - 12x + 4 + 1, that is
11 - 4x = 9x² - 12x + 5 ( add 4x to both sides )
11 = 9x² - 8x + 5 ( subtract 11 from both sides )
0 = 9x² - 8x - 6 or
9x² - 8x - 6 = 0 → B
Answer:
z ≈ 145.62
Step-by-step explanation:
using the sine ratio in the right triangle
sin18° = 
= 
( multiply both sides by z )
z × sin18° = 45 ( divide both sides by sin18° )
z = 
≈ 145.62 ( to the nearest hundredth )
If the angles are across from each other and the same degrees, they are vertical angles
if they add up to 90 degrees then they complementary angles
if they add up to 180 degrees they are supplementary angles
if the angles share a side, they are complimentary angles
