Answer:

The values of x and y that satisfy the equation are 2 and 2, respectively.

Step-by-step explanation:

Two complex numbers are identical if and only each pair of respective coefficients are identical on both sides. Then, we need to observe the following conditions:

Real component

$4\cdot x = 8$ (1)

Imaginary component

$2 = y$ (2)

The solution of this system of equations is $x = 2$ and $y = 2$ .

The values of x and y that satisfy the equation are 2 and 2, respectively.

Answer:

x=0

Step-by-step explanation:

The axis of symmetry: $x=\frac{-b}{2a}$ when the equation is $y=ax^2+bx+c$

The given equation is:

$y=x^2-6$

To make the a and b values more easily identifiable, we can rewrite it like this:

$y=1x^2+0-6$

Now, we can tell that a=1 and b=0. Plug these into the equation $x=\frac{-b}{2a}$ :

$x=\frac{-(0)}{2(1)}\\x=0$

Therefore, the equation for the axis of symmetry for the parabola is x=0.

How much was invested in the energy

Fofino [41]

The time it will take before Diego catches up with Linh will be after 8 hours

Let :

Distance traveled = d

Diego :

Travel speed = 75 mph
Travel time = t

Linh:

Travel speed = 60 mph
Travel time = t + 2

Recall :

Distance covered = speed × time

Distance covered by Linh = 60(t + 2)
Distance covered by Diego = 75t

Time when Diego catches up with Linh :

Diego's distance = Linh's distance

75t = 60(t + 2)

Solve for t ;

75t = 60t + 120

Collect like terms

75t - 60t = 120

15t = 120

Divide both sides by 15 to isolate t

t = (120 / 15)

t = 8

Hence, Diego will catch up with Linh after 8 hours.

3(r + 8) = 72. Do I use the Distributive property and multiply 3 by r and 8 and then continue or do I subtract 8 first? Help ple

Annette [7]

Distributive property then subtract...think of it as going the opposite of pemdas when solving for a variable
3r+24=72
3r=48
r=16
