➷ You have to find a value that, when added to -4, gives -1

This value is +3

The factored form would be (x - 4)(x + 3)

Expand this out:

x^2 + 3x - 4x - 12

==> x^2 -x -12 = 0

w = -12

➶ Hope This Helps You!

➶ Good Luck (:

Hello!

<em><u>Answer:</u></em>

<em><u>*The answer must have a whole number and a fraction.*</u></em>

Step-by-step explanation:

Lesson: Adding Fractions

First, you add by the whole number.

$1+2=3$

Then you combine by the fraction or number.

$\frac{3}{4}+\frac{2}{3}=\frac{17}{12}$

$3+\frac{17}{12}$

Next, you convert improper fraction into the mixed numbers.

$\frac{17}{12}=1\frac{5}{12}$

$3+1\frac{5}{12}$

And finally, add by the numbers.

$3+1=4$

Final answer: → $4\frac{5}{12}$

Hope this helps!

Thanks!

Have a great day!

Which formula gives the x-coordinates of the maximum values for y = cos(x)?

REY [17]

Answer with explanation:

The given trigonometric Function is,

y= cos x

→The maximum value of , cos x , is 1, at x=0 degree.

Cos x =1

→Cos x = Cos (0)degree,

$x=2 k \pi \pm 0$

→ for, k= An Integer

x=2 k π→→General formula that gives the x-coordinates of the maximum values for y = cos(x)

Ordered Pair =(x,y)=(2 k π, 1)

For, any value of , k in the given equation, y will be always 1.
