Step-by-step explanation:

The coefficient of the x term repesents the slope of the graph.

So we have y = 2x +- ( ).

We have to find our number term, so let's substitute x = 4 and y = 3.

(3) = 2(4) +- ( )

3 = 8 +- ( )

To make this right, the number term must be -5.

3 = 8 - 5

So the equation is y = 2x - 5.

Slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

Since we know that the slope (m) is 2 we can start plugging that into the equation:

y = 2x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(4, 3)

3 = 2(4) + b

3 = 8 + b

-5 = b

^^^Plug this into the equation

y = 2x - 5

Hope this helped!

22 less than the quotient of an unknown number and 35 is -25.

Agata [3.3K]

-22+(x/35)=-25
add 22 to both sides
x/35=-3
multiply both sides by 35 to cleaf raction
x=-105

number was -105

What are the zeros of (x-2)(x^2-9)

WARRIOR [948]

$(x-2)(x^2-9)=0\iff x-2=0\ or\ x^2-9=0\\\\x-2=0\ \ \ \ |add\ 2\ to\ both\ sides\\\\\boxed{x=2}\\\\x^2-9=0\ \ \ \ |add\ 9\ to\ both\ sides\\\\x^2=9\iff x=\pm\sqrt9\to \boxed{x=-3\ or\ x=3}\\\\Answer:\boxed{x=-3\ or\ x=2\ or\ x=3}$

Can anybody help me with this problem?

Answer:

Explanation:

According to the Unit Circle, sin π\6 is ½, so we plug this into the cosine function to get this:

cos π\6 - π\6 → cos 0 >> 1

** I do not have Unit Circle video uploaded yet, but if I need to, just notify me in the comments or on of course, You-Tube.

*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.

ANSWER

C. 58°

EXPLANATION

The sum of the interior angles of a triangle is 180°.

We sum all the three angles to obtain,

$8x+(14x+2)+(10x+50)=180$ .
