110% OF WHAT NUMBER IS 880? SHOW EVERY STEP PLZ:)

Nookie1986 [14]

So 110% of x is 880 means 1.1x=880

so 1.1x=880
multiply both sides by 10
11x=8800
divide both sides by 11
8800=88 times 100 88=8 times 11
8800/11=800
x=800

If f(x)=x*−81 and g(x)=(x−9)−1(x+9), find g(x)×f(x).

Nostrana [21]

F(x) = x²-81

g(x) = (x-9) -1(x+9)

= (x-9) -x-9

g(x) • f(x)

= [x²-81 ] • [ (x-9) -x-9 ]

=[ x²-81 ] • [ (x-x -9-9) ]
= [ x²-81 ] •[0-18]
= [ x²-81] •[ -18]

= -18•x² +-81•-18
= -18x²+1458

Progress:

JulsSmile [24]

Answer:

Option (1)

Step-by-step explanation:

Given inequality is.

4x + 5 ≥ 13

We will further solve this inequality,

(4x + 5) - 5 ≥ 13 - 5

4x ≥ 8

$\frac{4x}{4}\geq \frac{8}{4}$

x ≥ 2

Therefore, on a number line solution of x will be all values of x greater than equal to 2.

Which will be represented by and arrow starting with a solid point from x = 2 directing towards numbers greater than 2.

Option (1) will be the answer.
