Answer:

\Huge\boxed{k=2.5}

Step-by-step explanation:

Given -2.1k + 13 + 6.5k = 24 we need to isolate the variable using inverse operations

step 1 combine any like terms

sometimes there are not like terms but in this case there are. When there are like terms (must be on the same side of the = ) you add them together

-2.1k + 6.5k = 4.4k

now we have

4.4k + 13 = 24

Now we want to get rid of the 13

To do so we subtract 13 from each side

13 - 13 cancels out

24 - 13 = 11

now we have 4.4k=11

now we want to get rid of the 4.4

To do so we divide each side by 4.4

4.4k/4=k

11/4.4=2.5

we're left with k - 2.5

Given: y = 3x - 4. What is the x-intercept? (0, -4) ( 4/3 , 0) (0, 4/3 )
Vera_Pavlovna [14]

This equation is in slope-intercept form of y = mx + b form.

The m represented by the coefficient of the x term

represents the slope and b represents the y-intercept.

So our y-intercept is -4 and we can write this as the ordered pair (0, -4).

Create a quadratic equation that has complex solutions
svetoff [14.1K]

Answer:

x^2 + x + 2 = 0.

Step-by-step explanation:

The discriminant b^2 - 4ac is < 0 for complex roots.

So we can choose appropriate values for a, b and c.

Let b = 1,  a = 1 and  c = 2 so b^2 - 4ac = 1 - 4*1*2 = -7.

So our equation is:

x^2 + x + 2 = 0.
