Hello :
<span>1/5x-2=1/3x+8
let ; y = </span><span>1/5x-2 ..... (1)
y=1/3x+8 .....(2)
by (1) : 1/5 x =y+2
x = 5y +10....(*)
by (2) : 1/3x = y-8
x = 3y-24 ....(**)
(*) :5y-x = -10
(**) : 3y-x =24 ......( last answer )
</span>
Answer:
d is the answer i believe
Step-by-step explanation:
Answer:
525 feet.
Step-by-step explanation:
Difference in height
= 375 - (-150) Remembering that - * - = + :-
= 375 + 150
= 525 feet.
Answer:
The slope is : -8/1
Step-by-step explanation:
2-y=8x
We need to get “y” by itself , so subtract “ 2 “ from both sides
-y=8x-2
Then we still have to get “ y” by itself , but it’s Negative “y” now! Divide both sides by “ negative one “ (-y is just like -1y).
-y/-1 = 8x/-1 (-2/-1)
* I put the -2/-1 on () just to organize it *
y = -8x +2
2: y-intercept
-8: slope
[ y = -8x + 2 ] and this called the y-intercept form .✨
Answer:
4/3π(0.973r³)
Step-by-step explanation:
Volume of a sphere = 4/3πr³
Given the radius of dodge ball rd = r
radius of tennis ball rt = 0.3r
Taking their difference
Volume difference = 4/3πrd³ - 4/3πrt³
Volume difference = 4/3π(r)³ - 4/3π(0.3r)³
Volume difference = 4/3π(r³ - 0.027r³)
Volume difference = 4/3π(0.973r³)
Hence the differmce in volume is 4/3π(0.973r³)
