Answer:

The answer is negative nine

Step-by-step explanation:

When it comes to x = ?, divide the ANSWER by the mulitplicand. Example, -4x = 36 can be translated to 36 = -4 TIMES X, which here you have to use your head. Negatives cancel each other and the answer is positive, therefore -4 * -9 = 36.

Since it’s an inequality you will NOT be looking for what X equals.

Starting with -4x<36 (just assume it’s the less than equal to sign)
Divide both sides by -4 (because the 4 is negative you will also flip the sign)
Now you have
X (greater than or equal to) -9
This is your final answer

x (> or =) -9

Ania scored a total of 120 points this season so far and averaged 15 points a game. How many games has she played?

arlik [135]

She played 8 games. Since she earned a total of 120 points and 15 points per game you would divide 120/15=8

Which is true for

IceJOKER [234]

Hi!

Your answer is C.

The vertex is the point where two different rays meet, forming an angle.

It can also simply be the point where 2 straight lines simply meet.

Option A is NOT correct because a vertex is not angle, it is a part of an angle.

Option B is NOT correct because, if there's only one segment, we cannot form a vertex.

Line AB contains points A (−6, 3) and B (2, −5). Line AB has a slope that is

nirvana33 [79]

Slope of a line contatining the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)

so slope between (-6,3) and (2,-5) is
(-5-3)/(2-(-6))=(-8)/(2+6)=-8/8=-1

the slope is -1

A sequence is defined recursively using the formula f(n+1)=-0.5f(n). If the first term of the sequence is 120, what is f(5)?

kumpel [21]

Answer:
f (5) = 7.5

Explanation:
The function given is:
f (n+1) = -0.5 f (n)

We are also given that:
first term is 120
This means that:
f (1) = 120

We will get the other terms by substitution as follows:
f (2) = -0.5 f (1) = -0.5(120) = -60
f (3) = -0.5 f(2) = -0.5(60) = 30
f (4) = -0.5 f(3) = -0.5(30) = -15
f (5) = -0.5 f(4) = -0.5(-15) = 7.5

Therefore, f (5) = 7.5

Hope this helps :)
