Answer:
59.85
Step-by-step explanation:
So if each minute she uses 1.33 calories, you have to multiply it by 45. 45 times 1.33 is 59.85 so there you go. Ellen uses 59.85 calories during a 45-minute class.
Answer:
Step-by-step explanation:
Represent the sofa with S and the love seat with L.
So, we have:
--- Total Cost
Required
Determine the value of L
Substitute 2L for S in the first equation.
Divide both sides by 3
<em>Hence, a love seat costs 117.0</em>
<em></em>
<u>Using Graph</u>
See attachment for graph
S is plotted on the y-axis and L is on the x-axis.
The green line represents while the orange line represents
When the line of the graph is traced to the x-axis, we have:
Associative property!
The property states that when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends!
Hope this helps!
Answer:
slope is 5/4
Step-by-step explanation:
The equation of the line is written in the form
y = mx+b where m is the slope and b is the y intercept
y = 5/4x -7/4
The slope is 5/4 and the y intercept is -74
Answer:
-9 ≤ x < 2
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values span from -9 to 2. Since -9 is closed dot, we include it in our domain. Since -2 is open dot, it is excluded from our domain:
[-9, 2) or -9 ≤ x < 2
