Answer:
x = (22/17), y= (79/17)
Step-by-step explanation:
Just substitute x = 2y - 8 into y = 9x - 7 and solve.
-20 > 4 -2x Write the equation.
-20 -4 > 4-4 - 2x Subtract four from both sides.
-24/-2 > -2x/-2 Divide -2 on both sides.
Now, flip the inequality sign.
12 < x
Hope this helps :)
Answer:
A) 14°
Step-by-step explanation:
If α and β are the two angles other than 90° in a right triangle, then we have the relation between α and β as, α+β=90°.
Therefore, Sin α = Sin (90° -β) =Cos β.
So, we can write the reverse as if Sin α = Cosβ, then we have α + β =90°.
It is given that, Sin (3x-27) = Cos (5x+5).
Hence, we can write (3x-27) + (5x + 5) = 90
⇒ 8x = 90+27-5 =112
⇒ x = 14°
Therefore, option A. is correct. (Answer)
Answer:
Step-by-step explanation:
Common ratio r = a₂/a₁ = -4/(½) = -8
nth term = a₁rⁿ⁻¹ = ½(-8)ⁿ⁻¹
This can be further simplified to (-1)ⁿ⁻¹2³ⁿ⁻⁴
