Which of the statements about the x-axis are true?

1 answer:

3 0

The x axis is a horizontal line that intersects the y axis at the origin
in an ordered pair, x is the first number

I is true because they do intersect at the origin
II is false because x axis is horizontal
III is false because x is the first number
IV. is true because it is horizontal and it does pass through the origin

I and IV are true

Describe the process of rewriting the expression Please Help

Mazyrski [523]

Answer:

$x^{\frac{21}{4} }$

Step-by-step explanation:

Given expression is:

$(\sqrt[8]{x^7} )^{6}$

First we will use the rule:

$\sqrt[n]{x} = x^{\frac{1}{n} }$

So for the given expression:

$\sqrt[8]{x^{7}}=(x^{7} )^{\frac{1}{8} }$

We will use tha property of multiplication on powers:

$=x^{7*\frac{1}{8} }$

$= x^{\frac{7}{8} }$

Applying the outer exponent now

$(x^{\frac{7}{8} })^6$

$= x^{\frac{7}{8}*6 } \\= x^{\frac{42}{8} }\\= x^{\frac{21}{4} }$

7x−4≥−15+2x solve in interval notation

Leviafan [203]

Answer:

[-11/5,∞)

Step-by-step explanation:

1. Add 4 to both sides: 7x-4+4≥-15+2x+4

2. Simplify: 7x≥2x-11

3. Subtract 2x from both sides: 7x-2x≥2x-11-2x

4. Simplify: 5x≥-11

5. Divide both sides by 5: 5x/5≥-11/5

6. Simplify: -11/5

17. Solve the equation using square roots. x^2 + 5 = 41 a.+-36 b.no real number solutions c.6 d.+-6

Kipish [7]

Solve your equation step-by-step.

x^2+5=41

Subtract 5 from both sides.

x^2+5−5=41−5

x^2=36

Take square root.

x=±√36

x=6

or

x=−6

So your answer suppose to be C and D.
But if you were to put only one answer in the answering box, then just say C)

On the weekend for every 2 minutes you spend watching puppy videos you spend 9 minutes watching regular tv. If you spend 572 min

harkovskaia [24]

Answer:

104 mins, 468 mins

Step-by-step explanation:

Let the time spent on puppy videos = 2x

Where x is the number of weekends.

Time spent on regular TV = 9x.

So total time spent is 572 mins

i.e 2x + 9x = 572

i.e 11x = 572

So x = 52.

So time spent on puppy videos = 2 X 52

= 104 mins

So time spent on puppy videos = 9 X 52

= 468 mins.
