Complete the table of values for y=x^2-2

Mathematics
1 answer:
Harrizon [31]3 years ago
5 0

Step-by-step explanation:

a)

For each value of x, we need to solve for y.

Our equation is x² -2. This means that we multiply x by itself ( x * x = x²), and then subtract that value by 2.

Here is a list of the unfilled answers:

x = -2:

-2²-2 = -2 * -2 -2 = 4-2 = 2. -2 * -2 = 4 because two negatives multiplied together makes a positive.

x=-1:

-1²-2 = 1 -2 = -1

x=1

1²-2 = 1-2= -1

x=3:

3²-2  = 9-2 = 7

b)

In this graph, the y represents the vertical part and x represents the horizontal. For each value of y, there is a horizontal line that can be drawn. For example, when y=0, the bolded horizontal line near the bottom of the graph represents that. We then need to find the points on the line representing x²-2 where it touches the horizontal line of y=0. This happens when x=-1.5 and x=1.5, as it is between the positive/negative 1 and 2 values of x

The ages of Aman and Arun are in the ratio 5:7. Four years later the sum of their ages will be 56 years. What are their present
Viktor [21]

Answer:

Aman's age = 20, Arun's age = 28

Step-by-step explanation:

Let x = Aman's age

Let y = Arun's age

- - - -

x+4+y+4=56 (Sum of their age is 56 after 4 years in the future)

x+y+8=56

x+y=48

\frac{x}{y} = \frac{5}{7} (Ages are in the ratio 5:7)

x=\frac{5}{7}y

Now, we can use substitution to find for Arun's age:

x+y=48

\frac{5}{7}y+y=48

\frac{12}{7}y=48

y=28

∴ Arun is 28

To find for Aman's age, we can use substitution:

x+y=48

x+28=48

x=20

∴ Aman is 20

Hope this helps :)
