Answer 1
Answer:

Answer:

Livy could be 13 years old, and Cori could be 35 years old.

Step-by-step explanation:

Given : The system of inequalities  describes the relationship between Cori’s age, C, and Livy’s age L.

C + L > 43

C - 4L < 3

We have to determine the ages of Cory and Livy.

We will plot both the inequality in a graph.

Thus, below attachment shows the graph of the two given inequality

Let x axis represent the Cori’s age, C, and y - axis Livy’s age L.

Now we plot the given ages in the graph and those points lies in intersection will given the ages of Cori and Livy.

Thus, Only  (35 , 13) lies in the intersection,

We reject other points as the lies on dotted edges of graphs.

Thus, Livy could be 13 years old, and Cori could be 35 years old.

The function g(x) = 8x2 – 48x + 65 written in vertex form is g(x) = 8(x – 3)2 – 7. What is the vertex of g(x)?(–3, –7)
(3, –7)
(24, –7)
(–24, –7)

Answers

The answer is (3, -7). If the function is written in the form y = a(x – h)^2 + k, the vertex will be (h, k). Let's write the function 8x^2 – 48x + 65 in the form of a(x – h)^2 + k. g(x) = 8x^2 – 48x + 65. g(x) = 8x^2 – 48x + 72 - 72 + 65. g(x) = (8x^2 – 48x + 72) - 7. g(x) = (8 * x^2 – 8 * 6x + 8 * 9) - 7. g(x) = 8(x^2 - 6x + 9) - 7. g(x) = 8(x - 3)^2 - 7. The function is now in the form a(x – h)^2 + k, where a = 8, h = 3, and k = -7. Thus, the vertex is (3, -7).
