Solving for y, we add 5y to both sides and subtract 4, getting 9x-4=5y. Dividing both sides by 5, we get 9x/5-4/5=y. Since the slope is 9/5 (since 9/5*x=9x/5), we multiply it by -1 and find the reciprocal of it to get -5/9 as the perpendicular slope, so -5x/9+b=y. Plugging 1 in for x and -6 in for y, we get -5*1/9+b=-6 and by adding 5/9 to both sides we get -5-4/9=b , and since in y=mx+b y and x are variables, we end up with y=-5x/9+(-5-4/9) for slope intercept form.
To get it into standard form, we need it in ay+cx=b with a, b, and c being constants. Adding 5x/9 to both sides, we end up with y+5x/9=(-5-4/9) for standard form
Answer:

Step-by-step explanation:
Given:
- radius = 7 metres
- height = 2 metres
- π = 3.14
To Find:
Solution:
Use the formulae of the volume of cylinder:

where,
- π = 3.14
- r = radius
- h = height
According to the question:
- radius = 7 metres
- height = 2 metres
Substitute the values onto the formulae in order to find out the volume:






<u>Hence,we can conclude that:</u>
The volume of the cylinder is approximately
307.7m³.
Answer:
In Step 4, the inequality sign should be flipped.
Step-by-step explanation:
Whenever you multiply or divide both sides of an inequality by a negative number, you need to flip the inequality sign. So, in Step 4, when you divide both sides by -10, the sign should be flipped.
The final answer should be:
