Do you know how to find rate of change? X&Y intercepts? Zeros?
Rzqust [24]

#Rate of change

Rate of change is slope

If two points be (x1,y-1) and (X2,Y2) then

  • Slope=m=y_2-y_1/x_2-x_1

If a line be ax+by+c=0

  • m=-a/b

#X and y inetercept

If a equation given y=mx+b

  • To find x intercept put y=0
  • To find y inetercept put x=0

#Zeros

To find the zeros spot out the x inetercepts

The x values of the x intercepts are the zeros

If 40% of a number is 80 what is 25% of that number?
olga2289 [7]

Answer:

25% of 200 is 50

Step-by-step explanation

40% of a number is 80

.40 * n = 80

Divide each side by .4

.40 n/.4 = 80/.4

n = 200

The number is 200

Now lets find 25 percent of that number

.25 * 200 = 50

Type the correct answer in each box. Spell all words correctly, and use numerals instead of words for numbers.
Andru [333]

Answer:

Nate made a mistake. He should have got 24 as Least common factor.

Step-by-step explanation:

Given number are 8 and 12.

To find the GCF or LCF we have to list multiples.

For LCF

  • List the multiples of each number until at least one of the multiples appears on all lists.
  • Find the smallest number that is on all of the lists.
  • This number is the LCM.

For GCF

  • List the multiples of each number until at least one of the multiples appears on all lists.
  • Find the Biggest number that is on all of the lists.
  • This number is the GCF

The least common multiple of 8 and 12 is 24.

The Greatest common multiply of 8 and 12 is 4.

Hence, Nate is wrong. Nate should have found 24.
