<span>to isolate y first step as follows;
5x - 7y - 10
-7y = -5x -10 (change the 5x to this side as negative)
</span><span>then divide by -7 and you have
-7y = -5x + 10
--- --- ---
-7 -7 -7
then you havd:
y = 5/7x -10/7</span>
The answer to the question is letter C
152,909 rounded to the nearest hundred thousands is 200,000.
Rules of rounding numbers
1) if the number being rounded off is followed by 0, 1, 2, 3, and 4, round the number down.
2) if the number being rounded off is followed by 5, 6, 7, 8, and 9, round the number down.
1 is the number on the hundred thousands place. It is followed by 5. We round 1 up to 2. Thus 2 is now in the hundred thousands place.
Ground: y = 0
- 16t² + 128t + 50 = 0
Apply quadratic equation.
t = 0, 8 (rounded to the nearest second)
8 seconds
Answer:
<E= 147
<F= 33
<D= 90
Step-by-step explanation:
<E and the labeled angles are equal because they are vertical angles
<F and the labeled angles are supplementary so 180-147=33
<D is 90 because the angle next to it is a right angle which we know because it is L shaped and has a square in the corner :D
