Answer:
You will have to change this equation into slope intercept form which will be y=2x-4.
Step-by-step explanation:
To change this equation into slope-intercept form, you have to move the x. Do that by minus 6x on both sides. Once you move the x value, your equation will look like -3y=-6x+12. Now you have to divide all your three numbers by -3. Therefore your answer should be y=2x-4. Then going from there you will be able to graph this simple equation by going two spots to the right on the x-axis, and moving 4 spaces down in the y- axis.
Answer:
3(m+8)
Step-by-step explanation:
first you add m to 8, so you would do m+8. then you triple that, means multiply it by 3. so 3(m+8)
It would take you 35 minutes.
Since it takes 10 minutes to peel 4 potatoes, you can assume it would take 30 minutes to peel 12 potatoes (mulitiplying both numbers by 3). Then you'd add 5, instead of 10 because you are peeling 2 more potatoes than 12, instead of peeling 4, you'd divide 10 by 2 to get half the time it would take to peel half as many potatoes. Finally, add 30 and 5 to get you final answer of 35.
I hope this helps!
Step-by-step explanation:
24p - 60
= 12 * 2p - 12 * 5
= 12(2p - 5).
Answer:
17.8 meters
Step-by-step explanation:
Given:
before expansion railroad rail= 4 km
expansion= 16 cm
railroad makes an isosceles triangle at the center of the rail when it expands
The base of the triangle=4 km
As 1km=100,000 cm
thus 16 cm= 16/100,000 km
each side of this triangle= (4 + 16/100,000) / 2 = 4.0001 / 2 = 2.00008 km
One half of the isosceles triangle makes a right triangle with one of the side =4 / 2 = 2 km
and the hypotenuse = 2.00008 km
Using Pythagoras theorem to find the third side of this right angles triangle:
c^2=a^2+b^2
2.00008^2= 2^2 + b^2
2.00008^2 - 2^2=b^2
b=0.0178 km
b= 17.8 m
hence, approximately 17.8 meters would the center of the rail rise above the ground!
