The measures of two complementary angles are (3y − 1)° and (4y + 7)°. Determine the value of y. (Type number only)

blondinia [14]

Answer:

y = 12

Step-by-step explanation:

Complementary angles sum to 90 , so

3y - 1 + 4y + 7 = 90

7y + 6 = 90 ( subtract 6 from both sides )

7y = 84 ( divide both sides by 7 )

y = 12

Answer:

$\large\boxed{a=-3,\ b=-7\ and\ c=3}$

Step-by-step explanation:

$ax^2+bx+c=0$

We have:

$-3a^2=7a-3$ <em> subtract 7a from both sides</em>

$-3a^2-7a=7a-7a-3$

$-3a^2-7a=-3$ <em>add 3 to both sides</em>

$-3a^2-7a+3=-3+3\\\\-3a^2-7a+3=0\to a=-3,\ b=-7, c=3$
