Answer:

x=5

Step-by-step explanation:

Answer:

C) 5

Step-by-step explanation:

2^3=3x-7

2*2*2=3x-7

8=3x-7

3x=8+7

3x=15

x=15/3

x=5

Answer:

It's true when x = a positive number.

Step-by-step explanation:

I don't know how to explain this, so here we go.

The definition of absolute value is the distance a number is away from 0.

In other words, all numbers are now positive or 0.

If |-x| = x, it means x would have to be positive because, well, to prove that, we have to see what it couldn't be a negative number

if x was a negative number (-1), this is what we would get

|-(-1)| = -1

|1| = -1

1 = -1

That's not right!

And this happens in any negative number you do.

Because the absolute value of something cannot be negative

I cannot stress that enough

Since it is the absolute value of -x, x has to be positive, if it isn't, then there is no solution for x.

Any number greater than or equal to zero is a possible answer for the absolute value of something, but the absolute value of something cannot be a negative number

I hope this helps, let me know if you have any questions.

Answer:

-9 is the correct answer

Answer: 1 or D

Step-by-step explanation:

Answer:

1). The average speed is 17 mps (m per second). I know this because if you divide 34 m by 2, (in order to get the m per second) you will get 17 mps. Thats how i got my answer.

2). It would take 2.5 hours to travel 130km. I know this by dividing 139 by 52. I chose to do this because if you travel 52km/h, then dividing 130km by 52 will give you an answer

Answer:

A linear equation is an algebraic equation of the form y=mx+b. Where m is the slope and b is the y-intercept. A linear equation most times is called a "linear equation of two variables," where y and x are the variables.

Step-by-step explanation:

Answer:

the slope is 9/10 and the y-intercept is (0,3) I hope it helps

Answer:

the value of x is 2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

Given 3 parallel lines intersected by 2 transversals then the parallel lines divide the transversals proportionally, that is

[tex]\frac{3x}{4}[/tex] = [tex]\frac{7.5}{2.5x}[/tex] ( cross- multiply )

7.5x² = 30 ( divide both sides by 7.5 )

x² = 4 ( take the square root of both sides )

x = [tex]\sqrt{4}[/tex] = 2

Answer:

Answer:

x²-4x+7

-x²-6x-12

Step-by-step explanation:

1.) the first thing we do is expand the exponent (or mulitply  (x-2)(x-2) the images below will show you how to do that

We get x²-4x+4 and then just need to add three

x²-4x+7

2.)

We do the same thing (expand the exponent) and get x²+6x+9

which means so far we have

-(x²+6x+9)-3

carry out the negative sign and subtract 3

-x²-6x-12

Given:

The figure of triangle ABC.

To find:

The measure of angle A.

Solution:

From the given figure, we get

[tex]\angle ABC+120^\circ=180^\circ[/tex]                 (Linear pair)

[tex]\angle ABC=180^\circ-120^\circ[/tex]

[tex]\angle ABC=60^\circ[/tex]

According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.

[tex]\angle A+\angle ABC=105^\circ[/tex]          (Exterior angle theorem)

[tex]\angle A+60^\circ=105^\circ[/tex]

[tex]\angle A=105^\circ-60^\circ[/tex]

[tex]\angle A=45^\circ[/tex]

Therefore, the measure of angle A is 45 degrees.

Answer:

289.38 m^2

Step-by-step explanation:

(9.6)^2 x 3.14 = 289.38 m^2

The area of the circle is [tex]289.38\ m^2[/tex]

Since the  radius of 9.6 meters and we use 3.14 for π

We know that

The area of the circle is

[tex]= \pi r^2\\\\= 3.14\times (9.6)^2\\\\= 289.38\ m^2[/tex]

We simply applied the given formula so that the area of the circle could come

Therefore we can conclude that The area of the circle is [tex]289.38\ m^2[/tex]

Answer:

3 and 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

15y = 45x + 60 ( divide all 3 terms by 15 )

y = 3x + 4 ← in slope- intercept form

with slope m = 3

Given

6y = 12x + 36 ( divide all 3 terms by 6 )

y = 2x + 6 ← in slope- intercept form

with slope m = 2
