Answer:
y = -3x + 6
Step-by-step explanation:
We can first find the y intercept by looking at y when x = 0
y intercept = 6
We can then find the slope by looking at the patterns on the tables.
As we can see, the top row's pattern is +4 every time
The bottom row's pattern is -12
Slope = rise/run
-12/4 = -3
Therefore, the equation for the chart is y = -3x + 6
You are correct for 18a through 18c. Nice work.
18a. True (think of it as 21 is less than 27)
18b. False; 0.4 is the same as 0.40
18c. True. Three dollars is much greater than 20 cents
18d. False. 1.9 is the same as 1.90 and can't be smaller than itself
18e. False. The two sides are completely diferrent numbers.
18f. True. The value 6.2 is the same as 6.20
--------------------------------
For problem 19, you have to make the denominators the same. So multiply top and bottom of the first fraction by 10 to go from 4/10 to 40/100
If 40 is in the first box, then 40+40 = 80 is the final numerator. If this is over 100, then 80/100 = 8/10 meaning that 10 goes in the other box.
Answer:
The independent variable is b. The dependent variable is p. The equation that represents the relationship between the variable is b = 6p.
Step-by-step explanation:
If you read it carefully, it says that b is equal to 6 times p. Since p is time with 6 it is dependent and b is independent. Hope this helps, thank you :) !!
To find the y intercept of AB, first find the slope of AB: m=(1-(-1))/(2-14)=-1/6
the equation of line AB is y=-(1/6)x+b
use either of the given two points to find out b: 1=(-1/6)*2+b => b=4/3
BC is perpendicular to AB, so the slope of BC is the negative reciprocal of the slope of AB, therefore, the slope of BC is 6
Equation of BC is y=6x+b
find out b by using the coordinates of point B: 1=6*2+b => b=-11
the equation of BC is: y=6x-11
the x coordinate of point C: 13=6*x -11 =>x=4
Please double check my calculation.
Answer: False.
Step-by-step explanation: 4*3/5=60% of 4 since 3/5=60%
