Answer:
There is no answer to this question.
Step-by-step explanation:
First of all the variable is not in the equation.
Second of all, y=mx+b has only variables, it can only be simplified to
4(x² - 2) = 28
1. Distribute the 4
4x² - 8 = -28
2. Plug in 3 and -3
4(3)² - 8 = 28
4(-3)² - 8 = 28
3. Square 3 and -3
4(9) - 8 = 28
4(9) - 8 = 28
28 = 28
The reason both answers are the same is because whenever you put a negative number to an even power, the result becomes positive because any negative multiplied by a negative number is always positive.
28 = 28
Answer:
x = 8, y = 4
Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° = , thus
sin60° = = = ( cross- multiply )
x × = 8 ( divide both sides by )
x = 8
--------------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° = , thus
tan60° = = = ( multiply both sides by y )
4 = y × ( divide both sides by )
y = 4
Answer:
the two similar are the two side ones
