Answer:

y-coordinate of the solution is, -5

Step-by-step explanation:

Given the system of equations:

y = 6x-11

y= x^2+4x-10

Equate these two equations we have;

6x-11 = x^2+4x-10

Subtract 6x from both sides we have;

-11 = x^2-2x-10

Add 11 both sides we have;

0= x^2-2x+1

Using the identity rule:

(a-b)^2 = a^2-2ab+b^2

then;

x^2-2x+1 = 0

⇒(x-1)^2 = 0

⇒x-1 = 0

⇒x = 1

Substitute the value of x in y = 6x-11 we have;

y = 6(1)-11 = 6-11 = -5

therefore, the  y-coordinate of the solution is, -5

pantera1 [17]
The area of a circle can be found using:
pi x r^2 (where r is the radius)

If the area of the circle is 255pi, then:
pi x r^2 = 255pi

Now we need to make r the subject:

r^2 = 255 (cancel the pi on both sides)

r = square root of 255

r = 15.96871942

Answer: 15.96871942 feet
Hope the answer helps :)

Answer:

56

Step-by-step explanation:

So you just need to find 7 + what is equal to 63. To find this we have to do inverse operation, which means the opposite operation. So, we do 63-7 which is equal to 56. Therefore, the solution to the equation, or x is equal to 56 (C).

Hope this helps !!

1/3(9x-15)=4x<br> Please help me
aivan3 [116]

Answer:

Step-by-step explanation:

1/3(9x-15)=4x

Multiply each term by 3

9x - 15 = 3(4x)

9x - 15 = 12x

12x - 9x = -15

3x = -15

x = -15/3

x = -5
