Answer-

y = -1x or y = -x

Explanation-

Step 1: Look for a pattern in the x column and the y column.

X = -1, 3, 7, 11
(The pattern is that you add 4 with every number)

Y= 0, -4, -8, -12
(The pattern is that you subtract 4 with every number)

Step 2: Create and (if needed) simplify the slope

Slope = y/x

Slope -> -4/4

Simplified Slope -> -1

Step 3: Put it in slope-intercept form

Slope-intercept form -> y = mx + b

y = -1x + 0 -> y = -1x or y = -x

Answer:

For a single value of x function has more than one corresponding value of y which satisfies the equation.

Step-by-step explanation:

Function: A relationship between a set of inputs and a set of possible outputs, where exactly one output is associated with each input.

It means for an equation to represent a function any single value of x there should be only one corresponding value of y which satisfies the equation.

Now consider the given equation.

$x^2 + y^2 = 8$

If we put x=0 then we get two value of y i.e $\sqrt8$ and $-\sqrt8$ which satisfy the equation and therefore the equation is not a function.

Can someone tell me what 1/2 - 1/6 is would really appreciate it, thanks

timama [110]

Make denominator same first.

1/2 - 1/6

3/6 - 1/6

Now subtract numerators

(3-1) / 6

2/6

Now simplify

1/3

Final answer: 1/3

PLEASE HELP ASAP!<br><br>Construct an angle of 75° and write the steps of construction.

vlada-n [284]

Step-by-step explanation:

Steps of Construction

(i) Draw ray AB.

(ii) Construct ∠BAC = 60°.

(iii) Construct ∠BAD = 90°.

(iv) Bisect ∠CAD, so that ∠CAE = ∠EAD = 15°.

(v) We obtain ∠BAE = ∠BAC + ∠CAE = 60° + 15° =75°.

Hope this Helps!!!!

Answer:

D. x = 3

Step-by-step explanation:

The only way we could get a line of symmetry through this figure is to use a vertical line. The only way to get symmetry would be to put the vertical line though the point x = 3. When we do that, we can see that the end points of the base are both one unit away from the line of symmetry. The end points I'm talking about are the points at the coordinates (2, 4), and (4, 4)
