Simply plug your y intercept in for b. You’ll get y= -3x+4. Draw a simple graph and plot your y coordinate first at 4. Since your slope is -3, then from your point 4 on the graph go down 3 spaces and to the right 1 space. Continue on until you get a line. Also, from 4, go up 3 spaces and to the left 1 space to complete the line.
Answer:
x=20
Step-by-step explanation:
use proportions
121:11
or 11:1
take 10 and multiply it by 11 to get the length of the other side.
110
set the equation equal to that length
5x+10=110
-10 on both sides
5x=100
÷5 on both sides
x=20
Answer:
Step-by-step explanation:
Let's let B represent the amount of blue cubes, Y represent the amount of yellow cubes, and G represent the amount of green cubes.
We know that there are three times as many blue cubes as yellow cubes. In other words:
We also know that the are as five times as many green cubes as blue cubes. So:
If Sarah takes a random cube, the chance it will be a yellow cube will be the total amount of yellow cubes over the total amount of cubes. In other words:
We can simplify this. Let's substitute 5B for G. This yields:
Combine like terms:
We can then substitute 3Y for B. This gives us:
Multiply:
Again, add:
We can now cancel out the Y:
So, the chance of Sarah picking out a yellow cube is 1/19 or about 5.3% chance.
And we're done!
