First, take two points, and find the slope.
So now we have an equation:
y = 3/2x + b
Plug in the point (2,2) and solve for b.
2 = (3/2)(2) + b
2 = 3 + b
b = -1
The final equation that represents the relationship is y = 3/2x - 1.
A standard equation for a line is usually written as y=mx+b, m being the slope and b the y-intercept. We already have the slope, 7. To find the y-intercept we need to make an equation. The coordinates (1,2) will help us. We can plug the x from our point into the equation as well as our y. 1 is the x and 2 is the y. Therefore our equation is 2=7(1)+b. Now we solve. 7×1=7, so 2=7+b. Then we subtract 7 from both sides to get rid of the 7 on the right side. In addition, the 7 is positive so subtracting will get rid of it.
2=7+b
-7 -7
2-7 is -5. Therefore -5 is b.
Now we can make an equation.
y will remain y.
x will remain x.
m = 7
b = -5
y=7x+(-5) or y=7x-5
I hope this helped! (:
Answer:
Step-by-step explanation:
2πr=44
2×22/7×r=44
r=44×7/44=7
diameter=2×7=14
so obviously first of all find three sherical objects or balls of varioius sizes to make it easier get a large medium and small sized.
then on scratch paper sketch those objects (im assuming by the looks of it you would trace them if not just draw them then take measuring tape or a ruler across to measure said object) now you arent told what units to measure in but id assume to stick with one unit either inches or cm
mesure the length across which is the circumference
now you would just have to do your calculations by finding the radius and volume and surface area
remember volume is (*units) cubed and suface area is (*units) sqared
100+100+114 +x+x = 540
314 + 2x = 540
X= 113
Hope this helps!
