What the answer to this equation-3+5+2y-7y please show worj
2 answers:
-3+5+2y-7y
• first you combine like terms
• -7y and +2y are like terms because they both end with the variable "y"
•which gives you -5y because a negative and a positive you subtract and keep the sign of the larger number in this case would be -7y
• next you combine 5 and -3, since the numbers have opposite signs, you subtract and keep the sign of the larger number, which in this case would be 5 and the answer to +5-3 is 2.
Final answer: -5y+2

Answer:
a = √11 and b = 6
Step-by-step explanation:
Refer to attached picture for reference
for an right triangle with angle θ
we are given
cos θ = 5/6 = length of adjacent side / length of hypotenuse
hence
adjacent length = 5 units
hypotenuse length = 6 units
the missing side is the "opposite" length which we can find with the Pythagorean equation. in our case:
hypotenuse ² = adjacent ² + opposite² (rearrange)
opposite ² = hypotenuse ² - adjacent ²
opposite ² = 6² - 5²
opposite = √ (6²-5²) = √11
sin θ = opposite length / hypotenuse (substitute values above)
sin θ = √11 / 6
hence a = √11 and b = 6
