Answer:
9.7cm
Step-by-step explanation
According to the sine rule;
a/sinA = c/sinC
8/sin55 = c/sin82
Cross multiply
csin55 = 8sin82
c(0.8192) = 8(0.9903)
c = 8(0.9903)/0.8192
c = 7.9221/0.8192
c = 9.67
Hence the value of c to the nearest tenth is 9.7cm
Answer:
A
Step-by-step explanation:
7x² - 4x - 8 - [ -3x² - 3x - 3]
In subtraction, flip the sign of all terms in the minuend
7x² - 4x - 8
<u> 3x² + 3x + 3</u>
4x² - x - 5
1.)divide by 5 on each side to obtain
Abs(2x+3)=45
2x+3=45 or 2x+3=-45
2x=42 or 2x=-48
x=21 or x=-24
Answer: (14, 5)
===========================================================
Explanation:
Translating 5 units to the right means x becomes x+5. Whatever the x coordinate is, we add on 5.
Translating 4 units down means we go from y to y-4.
Overall, the point (x,y) becomes (x+5, y-4).
We can write the compact notation 
So for the specific point given, we can say:
The point (9,9) shifts to (14, 5)
It is simple, each y=3x so, lets just say that you have 8y, that would be equal to 24x. In other words, just multiply the number of y's, by 3
