Find y.<br> 30<br> 20 <br> Need help asap
Neporo4naja [7]

Answer:

y = 10

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = \frac{1}{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{y}{20} = \frac{1}{2} ( cross- multiply )

2y = 20 ( divide both sides by 2 )

y = 10

The domain of this function is {-12,-6,3,15}. Y=-2/3x+7
Evgen [1.6K]

Considering the given function, the table is completed as follows:

x|y

-12|15

-6| 11

3|5

15|-3

<h3>Which is the function?</h3>

The function is defined by:

y = -\frac{2}{3}x + 7

Hence, when x = -12:

y = -\frac{2}{3}(-12) + 7 = 15

When x = -6:

y = -\frac{2}{3}(-6) + 7 = 11

When x = 3:

y = -\frac{2}{3}(3) + 7 = 5

When x = 15:

y = -\frac{2}{3}(15) + 7 = -3

A line with a negative slope is perpendicular to one of the lines shown. What is its slope? Use the graph shown below. The Slope
goblinko [34]

Answer:

  • The slope for the red line is decreasing and hence the slope must be negative. -1x or simply -x
  • The slope of the blue line is increasing and hence positive: 1/2x
  • The solution to the equation is the intercept (2,3)

If log(x + y) = log 3 + ½log x + ½log y, prove that x² + y² = 7xy​
Free_Kalibri [48]

Answer:

See Explanation

Step-by-step explanation:

log(x + y) = log3 +  \frac{1}{2} logx+  \frac{1}{2} logy \\  \\ log(x + y) = log3 +    logx ^{\frac{1}{2}} +   logy ^{\frac{1}{2}}\\  \\  log(x + y) = log3 +    log(xy) ^{\frac{1}{2}} \\  \\ log(x + y) =  log[3(xy) ^{\frac{1}{2}}] \\  \\ x + y = 3(xy) ^{\frac{1}{2}} \\  \\ squaring \: both \: sides \\  {(x + y)}^{2}  =  \bigg(3(xy) ^{\frac{1}{2}} \bigg)^{2}  \\  \\  {x}^{2}  +  {y}^{2}  + 2xy = 9xy \\  \\  {x}^{2}  +  {y}^{2}  = 9xy - 2xy \\  \\   \purple{ \bold{{x}^{2}  +  {y}^{2}  = 7xy}} \\ thus \: proved
