Answer:

(4,4)

Step-by-step explanation:

4x-2y=8

y=1/2x+2

Since the second equation is solved for y, I will use substitution

4x - 2(1/2x +2) = 8

Distribute

4x - x -4 = 8

Combine like terms

3x -4 = 8

Add 4 to each side

3x-4+4 = 8+4

3x = 12

Divide each side by 3

3x/3 = 12/3

x = 4

Now we need to find y

y=1/2x+2

y = 1/2(4) +2

y = 2+2

y =4

The solution is (4,4)

Find the vertex and axis of symmetry for f(x)=2x^2-1

vfiekz [6]

<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>

Solution:

Given is:

$f(x) = 2x^2 - 1$

We have to find the vertex and axis of symmetry

The general equation is given as:

$f(x) = ax^2 + bx + c$

Comparing with given equation,

a = 2

b = 0

c = -1

The axis of symmetry is given as:

$x = \frac{-b}{2a}$

$x = \frac{0}{2(2)}\\\\x = 0$

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

$f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1$

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)

the probability of spinning an odd number on a spinner is 62 percent . What is the probability of not spinning an odd number?

Viktor [21]

Subtract the percent of getting odd from 100 percent.

100 - 62 = 38%
