Answer:
In BOLD.
Step-by-step explanation:
f(x) = (x - 1)(x + 7)
Convert to vertex form.
= x^2 + 6x - 7
= (x + 3)^2 - 9 - 7
= (x = 3)^2 - 16
So the vertex is at (-3, -16)
Also, as the vertex is a minimum the graph is increasing on interval x > -3.
From the graph we see:
The graph is positive on the interval
where x < -7 and x > 1.
- and negative where
-7 < x < 1.
Answer:
Cost of ordering t-shirts the same at both sides is 7
The cost is $85
Step-by-step explanation:
let x equal the number of tshirts
Hence:
15 + 10x = 50 + 5x
10x-5x= 50-15
5x = 35
35/5x
x = 7
Therefore the cost of ordering t-shirts the same at both sides is 7
The cost is $85
The Probability of choosing a green marble out of total 29 marbles is 11/29.
What is the Probability?
Probability defines the likelihood of occurrence of an event. There are many real-life situations in which we may have to predict the outcome of an event. We may be sure or not sure of the results of an event. In such cases, we say that there is a probability of this event to occur or not occur.
Total number of marbles = 11 Green + 18 Silver = 29 marbles
Number of Green marbles = 11
Probability = Number of green marble / Total number of marbles
= 11 / 29
Thus, The Probability of choosing a green marble out of total 29 marbles is 11/29.
