Which interval or union of intervals represents the values for which ​f(x)​ is ≤ 0? Select the correct choice below and fill in
boyakko [2]

Answer:

(-∞, -1]∪{5}

Step-by-step explanation:

We know that:

f(x) ≤ 0 is true if the graph of the function is intersecting the x-axis or below the x-axis.

So we can just look at the graph, we can see that in the interval:

(-∞, -1]   (the value x = -1 is included, that is why we use the symbol ] instead of the parenthesis)

the graph is below or intersecting the x-axis

and this also happens at x = 5 or just denoted as {5}

Then the correct notation is:

(-∞, -1]∪{5}

Part A,
I would assume the triangles are similar so
6y=4y+18
minus 4y both sides
2y=18
divide 2
y=9

Part B
sub for y
6(9)=54
the angle is 54

4. I actually forgot proofs, let me think
dunno this one
I would say cory is wrong



3rd attachment
5. since 8≠9, it is not a bisector of any sort nor is it equidistant from T and R
answer is point A is not on a bisector


4th attachment
it is not perpendicular in any way
if we assume that TXA=RXA, then the first and last options are right


5th attachment
7.
those 2 triangles are equal because of Side-angle-side
they have to be equal 2x=3x-5
minus 2x both sides
0=x-5
add 5
5=x
x=5

8.
it would be isocelseese
because the 2 sides are equal

Simplify 7 square root of 3-4 square root of 6 plus square root of 48 minus square root of 54
raketka [301]

Answer:

B) 11√3 - 7√6

Step-by-step explanation:

√48 can be simplified to <em>4√3</em>, and √54 can be simplified to <em>3√6</em>.

The equation is now <em>7√3 - 4√6 + 4√3 - 3√6</em>.

This can be grouped into <em>(7√3 + 4√3) + (-4√6 -3√6)</em>.

We get 11√3 - 7√6.
