65% of 39 is 60 the answer is 60
Answer:
its (-1/2,-5/2),(2,5)
Step-by-step explanation:
Substitute 2x2−3 for y into y=3x−1then solve for x.
So what they are saying is the sum of 2x +13=75
Therefore we can just solve for 2x, our unknown value.
2x+13=75 now subtract 13 and divide by 2 from both sides of equation to not change the equation
x+13-13=75-13
This leaves us with
x=(75-13)/2=31 therefore x=31 or our unknown value is 31.
I hope this helped. Any questions please just ask. Thank you.
When doing trigonometric ratios remember SOHCAHTOA
SOH = sin=opposite/hypotenuse CAH= cos = adjacent/hypotenuse
TOA = tan = opposite/adjacent
The answer is A) tanY = 7/4 tanZ = 4/7
