Can anyone help me on what’s -4 - (-3) plsss it’s for my math test

ololo11 [35]

Answer:

-1

Step-by-step explanation:

It is negative 1 because the signs for the -3 are the same so you keep the -4, change the - to a +, then flip the negative 3.

Hope this helps!

A parabola opens up and passes through (-4, 2) and (6, -3). How do you know that (-4, 2) is not the vertex

Ainat [17]

Answer:

Step-by-step explanation:

The minimum is at the vertex of this parabola because it opens up.

Now if (-4, 2) is the minimum then all the y values on the parabola must be > 2,

But we are given that y = -3 is on the graph ( the point (6,-3) - that is y < 2 here,

Therefore (-4, 2) cannot be the vertex .

Help me please. How to prove this ?

podryga [215]

Answer:

First, you want to divide the numerator and denominator by the cosine(x), and afterwards, it looks like this...

$\frac{tan~x+1}{tan~x-1}$

Include 45 as one of the parameters and correlate with tan.

$\frac{tan~x+tan~45}{tan~x-tan~45}$

Next, you want to multiply the numerator and denominator by the conjugate of the denominator, in this case, tan x + tan 45.

Lastly, simplify, and you have the answer as tan(45 + x)
