Answer:
3+2c
Step-by-step explanation:
To translate the phrase into an algebraic expression, you have to analyze the information provided. Three dollars more than twice the cost of a bowl of soups means that given that c is the costs of a bowl of soup, you have to multiply c for 2 as the phrase says twice the cost. Also, it says three dollars more which means that you have to add 3. According to this, the expression is: 3+2c.
So we know that:
3(-8 + 4v) = 8v
To find v, first simplify the left hand side:
-24 + 12v = 8v
Then group the "v's" over to the right:
-24 = -4v
-6 = -v
So v = 6
Hope this helped
Answer:
69
Step-by-step explanation:
It's 69 because 69 is in the middle of all of this data when it is put in order from least to greatest.
To determine which values of x we would use for creating a graph of a parabola, we need to know where the line of symmetry, or the axis of symmetry is. For that we can use the equation:
y=(x-h)+k, where we know h and k.
From this equation we can see that the line of symmetry is passing trough x=h.
And now we can determine which values do we need to add to h and to subtract from h to get values of x to create the table of values to plot a parabola.
