Match each equation to equivalent equation. -4x+3y=20 -6x-2y=10. 2x +5y=18

Answer:

4x + 10y = 36  ≡  to 2x + 5y = 18

As you can see, the the coefficients on the first one are double those in the second.

12x - 9y = -60  ≡  to -4x + 3y = 20

In this case, the terms in the first one are all the same, but multiplied by -3

And by simple elimination we can say:

-24x - 8y = 40 ≡ -6x - 2y = 10

In this case, the terms of the first equation are equal to those of the latter, but all multiplied by 4.

How would you explain to someone the rules of a horizontal translation where we are subtracting from the inputs(within the paren
chubhunter [2.5K]

Answer:

Ok, we know that we can write a horizontal translation as:

y' = f(x - A)

where if A is positive, this moves the graph of f(x) A units to the right.

Why is this?

Ok, let's compare:

y = f(x)

and

y' = f(x - A)

in y, when x = 0 we have f(0).

While to have this same point in y', we need to evaluate in x = A.

f(A - A) = f(0).

Then the value f(0) is now at x = A, this means that the point moved A units to the right.

And you can do this for all the values, so you will find that the entire graph of f(x) has ben moved A units to the right.

Find what equals to x and what equals to y
Nuetrik [128]

Answer:

x=15√2  y=90 degrees.

Step-by-step explanation:

Thanks to the Pythagorean Theorem we know that with any right triangle, A^2+B^2=C^2. In this case we can use 15^2+15^2=sqrt of 450. The square root of 450 is 15 times the square root of 2. Thus x=15√2. Now we need to find y. All angles in a triangle add up to 180 so if we have 45+45+y=180 then y=90.

How many times as many circles will there be at stage 21 compared to stage 20
babymother [125]

Answer:2^{10}\ circles

Step-by-step explanation:

Given

Stage 20 has 2^9 circles

Considering at each consecutive stage circle doubles itself

So at stage 21, there will be 2\times 2^9=2^{10} circles
