Complete the table of values for y=x^2-2
Harrizon [31]

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

Find the value of x :)))))
Nataly [62]

Answer:

A x =30

Step-by-step explanation:

(y+x)  and (y-x)  make a straight line so they add to 180 degrees

(y+x)  + (y-x) = 180

Combine like terms

y+y+x-x=180

2y=180

Divide by 2

2y/2 = 180/2

y= 90

(y+x)  and 2x  make a straight line so they add to 180 degrees

y+x+2x = 180

Combine like terms

y+3x = 180

Since we know y we can substitute it in

90+3x = 180

Subtract 90 from each side

90-90+3x= 180-90

3x = 90

Divide by 3

3x/3 = 90/3

x= 30
