k = 1.33 or 1 1/3
Formula of Direct variation. Where y is equal to the product of the constant of variation times x.
y = kx
16 = k * 12
k = 16/12
k = 1 4/12 = 1 1/3
Constant of variation is 1 1/3 or 1.33.
Mixed numbers are basically sometimes a sign of division. You need to turn the mixed number into an improper fraction.
Steps:
Multiply the whole number by the denominator of the fraction and then add that product to the numerator. Leave the denominator as it is before.
Example:
2 1/4
2x4=8
8+1= 9
Answer: 9/4
Then you can divide!
Answer:
Y=mx+b Is a linear equasion because if you plot the x and y on a graph it always shows a straight line.
Step-by-step explanation:
For example, y=7x+9,
When x is 1 y is 16, and
when x is 2 y is 23.
When you put those two points on a graph and connect the dots with a ruler, you get a straight line, and you will automatically find that when x is 3 y is 30.
Answer:
1) d < -2
2) b < 3
Step-by-step explanation:
1) d+3< 1
subtract both sides by 3
d+3 -3 < 1-3
d<-2
2) b+6< 9
subtract both sides by 6
b+6 -6 < 9 -6
b< 3
