Answer:
y=5x+9
Step-by-step explanation:
Firstly, we have to use the equation y=mx+b, where m is the slope and b is the y intercept.
We know that m=5, x=0 and y=9.
So why not plug them into the equation to find b?
9=5(0)+b
9=0+b
9=b
Therefore, y=5x+9 is your final answer.
Well, it depends on the school. Do you have a list of the classes?
Answer:
There are no real factors for this.
Step-by-step explanation:
We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or
We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.
Let's use the 2nd approach.
Here, a = 9, b = -4 and c = 1.
Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.
Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.
