Step-by-step explanation:

For the first one,

2x < 10

Divide both sides of the inequality by 2,

2x ÷ 2 < 10 ÷ 2

x < 5

Now, for the second one,

x/2 > 3

Multiply both sides of the inequality by 2,

x/2 × 2 > 3 × 2

this will cancel the fraction and will give us,

x > 6

That's it! I hope this explanation was useful enough ;)

Find the limits The answer is - 3/4

Kipish [7]

Hello from MrBillDoesMath!

Answer:

This is a puzzling one! The answer is indeed -3/4 but I was unable to prove it using mathematics appropriate to the "middle school" level. Sorry I couldn't be more helpful.

(To prove it I generated the first few terms of its Laurent series, a Calculus topic. The first few terms are -(3/4) + (41/64x) + and as x approaches minus infinity the term with "x" in the denominator goes to zero, leaving the constant value -3/4 as the answer. )

Thank you,

MrB

Keep in mind that the graph counts in twos.

The factored form of the polynomial deals with the zeros in the graph. Identify the zeros in the graph:

Zeros at:
x = -4, (-4,0)
x = 4, (4,0)

Both values must be inputted into the answer and result in an output of 0, so the answer will be C. (x+4)(x-4).

Proof:

x = 4:
$(4+4) \times (4-4) = 8 \times 0 = 0$

x = -4
$(-4 + 4) \times (-4 - 4) = 0 \times -8 = 0$

Use forward or backward substitute to conjecture a closed formula which describes the nth term of the sequence an = an-1 – n, wh

WINSTONCH [101]

The closed formula for an = an-1 – n will be found using the formula for arithmetic sequence given by:
an=a+d(n-1)
where
a=first term
d=common difference
n=number of terms
From the formula given:
a=4
d=n
thus the formula will be:
an=a+n(n-1)
an=4+n(n-1)

Pls help ASAP I need a good grade

Answer:

t = -41.6

Step-by-step explanation:

To solve for the variable t, you must isolate it on one side of the equation. $-\frac{t}{6.5} =6.4$ , multiply both sides of the equation by -6.5 and you will get t = 6.4 * (-6.5) or t = -41.6.
