Answer:

Answer D

Step-by-step explanation:

there needs to be a filled circle since the symbol says "or equal to".

then the arrow needs to point to the left indicating that the answer to x is less that 7, so the answer is D

Answer: D

Step-by-step explanation: To graph x ≤ 7 on a number line, we start with a closed dot at 7. The reason we use a closed dot in this problem is that not only is <em>x</em> less than 7 but it's also equal to 7.

We then draw an arrow going to the left to

represents all numbers less than -7.

The line underneath the sign means that you are including

that number as a solution to the inequality.

Write 85% as an frotion in simpfulest form

luda_lava [24]

85% is the same as 85/100.

85/100 means you can take a 5 out.

17/20 is completely simplified.

Hope this helps!

Does the following infinite series converge or diverge? 1/3+2/9+4/27+8/81+...

PilotLPTM [1.2K]

Note that A and D are ludicrous choices, so you can throw them away outright. (Any divergent series cannot have a sum, and any convergent series must have a sum.)

The sum is certainly convergent because it can be written as a geometric sum with common ratio between terms that is less than 1 in absolute value.

$S=\dfrac13+\dfrac29+\dfrac4{27}+\dfrac8{81}+\cdots$
$S=\dfrac13\left(1+\dfrac23+\dfrac{2^2}{3^2}+\dfrac{2^3}{3^3}+\cdots\right)$

We can then find the exact value of the sum:

$\dfrac23S=\dfrac13\left(\dfrac23+\dfrac{2^2}{3^2}+\dfrac{2^3}{3^3}+\dfrac{2^4}{3^4}+\cdots\right)$

$\impliesS-\dfrac23S=\dfrac13$
$\implies\dfrac13S=\dfrac13$
$\implies S=1$

So the answer is B.

Use the information given to enter an equation in standard form.

Greeley [361]

Answer:

y = -2x + 25

Step-by-step explanation:

A standard equation can be in slope-intercept form: y = mx + b

m is the slope, b is the y-intercept.

Plug in the given slope.

y = -2x + b

To find b, plug in the given point (9, 7).

7 = -2(9) + b

Multiply.

7 = -18 + b

Add 18 to both sides to find b.

25 = b

Plug this into your standard equation.

y = -2x + 25

Check by plugging in the given point again.

7 = -2(9) + 25

7 = -18 + 25

7 = 7

Your answer is correct!

Hope this helps!

What is the range of numbers that will win the game for your player?

Vikki [24]

Well range is the difference between the highest and lowest numbers so 20-7 is 13
