Answer:

x = -1

Step-by-step explanation:

30 = 2.5(10)(-2x)  - you multiply by each

30 = 25 - 5x        - then pass 25 to the other side and subract

5x = - 5x               - then divide 5 / -5

x = -1                     - and you have the answer

Answer:

x= -1

Step-by-step explanation:

distribute 2.5 through the parenthese

30=25-5x

move variable to the left hand side an change its sign

5x+30 =25

move constant to the right hand side and change the sign

5x=25 -30

calculate the difference

5x= -5

divide both sides of the equation by 5

x= -1

Hope this helps!!! I would really appreciate a brainliest???

Is 69/100 and 6/10 equivalent fractions
zubka84 [21]
No. If you divide 69 by 100 you would get 0.69. If you divided 6 by 10 you would get 0.6. Therefore 69/100 and 6/10 is not equivalent.

The two polygons above are similar. The scale factor of the smaller polygon to the larger polygon is 3. The area of the smaller
Softa [21]
You would think it was 3 * 12 = 36. Not so. All polygons have to be broken down into some figure that will give 2 dimensions that are at right angles to each other. That would mean that
d1 * d2 = Area for the small polygon
3d1 * 3d2 = area of the larger polygon

What that means is that the area of the larger one is 9 times the smaller one.
Area large = 12 * 9 = 108 square units. <<<<< answer.

If you find this hard to be leave try it with a square.
Suppose you have a square (the small one) that is 3 cm by 3 cm
The small one has an area of 3*3 cm^2 = 9 cm

Now you have another square that is 3 times larger. That means that each side is 3*3 = 9
So s = 9
Area = s^2
Area = 9^2 = 81 cm^2
81 is 9 times larger than 9 just as you would think.

How would you describe the relationship between the real zeros and x-intercepts of the function y = log (x-2)?
lakkis [162]

Answer:

When you set the function equal to zero, the solution is x = 3; therefore, the graph has an x-intercept at x = 3.

Step-by-step explanation:

The given function is y=\log (x - 2).

So, for real zeros and x-intercept, the y-coordinate must be equal to zero.

Then it becomes 0 = \log (x-2)

⇒ x - 2 = 1 {Since log 1 = 0}

⇒ x = 3

Therefore, when you set the function equal to zero, the solution is x = 3; therefore, the graph has an x-intercept at x = 3. (Answer)
