Answer:

x=29, y= 14

Step-by-step explanation:

y=16-2(move the 2 over to isolate y.) y=14. now input 14 in the bottom equation. x= 2(14)+1, 2×14=28, 28+1=29. x=29, y=14

For the 51-deg angle, y is the opposite leg, and 12 is the hypotenuse.
The trig ratio that relates the opposite leg and the hypotenuse is the sine.

sin A = opp/hyp

sin 51 deg = y/12

y = 12 * sin 51 deg

y = 9.3

1=10^0 into logarithmic form

Tatiana [17]

Answer:

$0 = log_{10} 1$

Step-by-step explanation:

Base for the exponent and for the logarithm are the same!

10^0 is the <u>exponential</u> form where 10 is the base and 0 the exponent

$log_{10} 1$ is the l<u>ogarithm</u> form where 10 is the base

To solve $log_{10} 1 =$ ask the question :

To what power should I raise the base 10 to obtain the number 1 ?

The answer to the power 0 therefore

$log_{10} 1 = 0$

$1 = 10^{0} -is-the- exponential -form\\0 = log_{10} 1 - is -the -logarithmic -form$
