2/3 x - 1/5 x = x - 1

Change the fractions to have the same denominators:

10/15 x - 3/15 x = 15/15 x - 1

Simplify the left side of the equation:

7/15 x = 15/15x - 1

Get everything to the right side of the equation:

0 = 8/15 x - 1

Move the (1) to the left side:

1 = 8/15x

Multiply 15 to both sides:

15 = 8x

Divide both sides by 8

15/8 = x

Answer is x=8/15

Answer:

Step-by-step explanation:

In the graphing calculator, I tried out the different answers, and I think this graph matches yours pretty closely. x is multiplied by a number greater than one, and it looks like instead of expanding/stretching open, it folded in more, which is compressing.

Find an equation of the curve that passes through the point (0, 4) and whose slope at (x, y) is x/y.

jolli1 [7]

1/2y^2=1/2x^2+8. The curve's slope at (x,y) is x/y, so dy/dx=x/y. To solve this differential equation, rearrange it to: y*dy=x*dx, and by integrating both sides, we get 1/2y^2=1/2x^2+C (some constant). Plug in (0,4) into this equation, 8=0+C, so C=8. The curve's equation is 1/2y^2=1/2x^2+8.

If two triangles are congruent, which of the following statements must be true? Check all that apply.

bonufazy [111]

Answer:

All statements are correct for two congruent triangles

Step-by-step explanation:

If two triangles are congruent than the rules states that

Triangles are congruent when all corresponding sides and interior angles are congruent. The triangles will have the same shape and size, but one may be a mirror image of the other.

As the fig shows two triangle

Δ PQR

Δ LMN

All three corresponding sides of triangle are congruent

all three corresponding angles are congruent

Both triangle are of same size

Both are of same shape

hence all the statements are CORRECT

-5x=60

The first thing we want to do is to divide -5 on both sides. We do this because -5x, is the same as -5 times x and we want to do the inverse of that.

After we divide on both sides, we get x=60/-5

We know that 60 divided by -5 is -12.

Therefore our answer is: x=-12

----------------------------------------------------------------------------------------------------------

5= n + 2

We always want to get the variable to be alone, so if we subtract by 5 we would be doing the opposite of getting the variable alone. Although, if we subtract by 2 on both sides, we would get the variable alone and the answer would be 3=n

Therefore our answer is: False

----------------------------------------------------------------------------------------------------------

2(x-7)

By looking at this question, we see x being subtracted by 7. Then we see that 2 is being multiplied to that.

Therefore our answer is: C

The product of a number and 4 increased by 8

In these types of questions, it's smart to break it up. We will start with the product of a number and 4. We know that a number is a variable and if we look at the multiple choice answers we can see that the variable they chose to use is n. We also know that a product is when numbers get multiplied. So that means 4 and n get multiplied which turns into 4n.

For the other part of the problem, we know that increased by 8 means added my 8. Now that we got our answers, we put then together.

Therefore our answer is: A 4n+8
