Draw a graph which joins the points (100, 120) and (50, 95) and has a slope = 2
Draw a graph which joins the points (120, 100) and (95, 50) and has a slope = 2
Draw a graph which joins the points (120, 100) and (95, 50) and has a slope = 0.50
Draw a graph which joins the points (100, 120) and (50, 95) and has a slope = 0.50
A graph of y against x means that x is the independent variable and y is the dependent variable. Notice that the charge (y) depends on the number of minutes (x). Therefore, the points that we are going to join to make our graph will have coordinates (x, y)
We know that the company charges $120 for 100 minutes, so x=100 and y=120. Therefore, our first point will be (100, 120)
We also know that the company charges $95 for 50 minutes, so x=95 and y=50. Therefore, our second point will be (50, 95)
Now, to find the slope between our tow points, we are going to use the slope formula:
where
are the coordinates of the first point
are the coordinates of the second point
We know from our points that ,
,
, and
. So let's replace those values in our formula to find
Now that we have our slope, we can use the point-slope formula to complete the equation of the line joining our two points
Answer:
Draw a graph which joins the points (100, 120) and (50, 95) and has a slope = 0.50
Step-by-step explanation:
A=2800,B=120,C=140,D=6
Answer:
A=2,800 B=120 C=140 D=6
Step-by-step explanation:
4*7 is equal to 28, then 40*70 is equal to 2,800.
when you multiply a 2-digit number always multiply the first digit from the first number with the first digit from the second number and think of them as single digits, for example, I don't know how to do 30*40, first, take the 3 and the 4 then multiply them. 3*4 equals 12, then you take the 0s and add them to the number, and now we have 1200! The same goes for 42*73, I hope this helps!
uarts = ____ cups
Answer:
Step-by-step explanation:
=>
Cross Multiplying
=> x * 3 = 5 * 17
=> 3x = 85
Dividing both sides by 3
=> x = 85/3
=> x = 28.3 (To nearest tenth)
Answer:
Step-by-step explanation:
The proportion is given,
We need the x variable isolated on one side, so we can find the value of x that makes the proportion true.
Multiply both sides of the equation by 5.
Simplify the equation.
The value of x that makes the proportion true is 28.3 (rounded to nearest tenth place).
