Answer:
y=3/4x-2
Step-by-step explanation:
y=mx+b
the b is the y-intercept so find the y-intercept of the line:
which is -2
the slope you need to find two points and look how many times do you need to rise or run to get the answer: 3/4
Hope this helps!
Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)
Answer:
3:5
Step-by-step explanation:
Let's create a ratio
Mushroom : Cheese
15 : 25
⬆The ratio above can be simplified
Divide both sides by 5
3 : 5
The answer is 3:5
Hope this helps :)
Have a nice day!
Answer:
1000+700+6+160+ 4320
Step-by-step explanation:
- 1 x 1000= 1000
- 7 x 10 = 70
- 6 x 1 = 6
4320+1000+160+70+6
I just did it in order.
Just in case you need that added
The diameter of the table is 42 inches. The radius of the table is half of the diameter of the table, so the radius of the table is 42/2 = 21 inches.
Add on 8 inches to the table radius to get: 21+8 = 29
So the radius of the table cloth is r = 29
Plug this into the area of a circle formula
A = pi*r^2
A = pi*29^2
A = pi*841
A = 841pi
A = 841*3.14
A = 2640.74
The approximate area of the table cloth is 2640.74 square inches.
