Step-by-step explanation:
(1) Create a table containing a few values of x and y
y - 3 = ½(x + 2)
y = ½(x + 2) + 3
x y
-10 -1
-6 1
0 3
6 7
10 9
(2) Plot your points
Draw dots at the coordinates of each point.
(3) Draw the graph
Draw a smooth line through the points.
Extend the line in both directions to the edges of the plot area.
Your graph of y - 3 = ½(x+2) should look like the figure below.
Have a beautiful day!
Answer:
9 dollars
Step-by-step explanation:
Solve with a system of equations
Let adult tickets be a and student tickets be s
1. 8a + 13s = 176
2. 4a + 4s = 68
3. s = 17 - a
Equation 2 is friendlier, so let's divide all the numbers by 4.
a + s = 17
Equation is s = 17 - a
Substitute s in equation 1
8a + 13(17-a) = 176
8a + 221 - 13a = 176
221 - 5a = 176
5a = 45
a = 9
The price of an adult ticket is 9 dollars
Hope this helps :)
Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is

There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
The answer is 76/98 because 22+76 is 98
