Cuál es el valor absoluto de/ 9-15 /

1 answer:

6 0

Hi there! The anser is 4

First we need to find the value between the stripes. Hence, we need to subtract 15 from 9. Then we get 9 - 15 = - 4. Finally we have to realise that the absolute value stripes make the value insides those stripes positive. So, we get the following:
I 9 - 15 I = I - 4 I = 4

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?

ale4655 [162]

Answer:

(x + 4)^2 + (y – 9)^2 = 25

Step-by-step explanation:

The standard form for a circle is

$(x - h)^{2} + (y - k)^{2} = r^{2}$ where (h, k) is the center and r is the radius

In your case, h = -4 and k = 9 and r = 5

So, (x + 4)^2 + (y – 9)^2 = 25

I’m not sure what to do..

Answer:

x=291/76

Step-by-step explanation:

Convert:

1/2x(6x+ 1/2)=-0.8x+16-1.2

Remove parenthesis and move terms:

3x+1/4=-0.8x+14.8

Collect the like terms and convert:

3x+0.8x=14.8-1/4

Subtract the fractions:

3.8x=74/5-1/4

Divide both sides by 3.8:

3.8x=291/20

x=291/76
