Given: f(x)=x^2 g(x)=x-1 Find f(g(2))+g(f(-1))

Mathematics
1 answer:
Marina CMI [18]2 years ago
8 0

Answer:

-1

Step-by-step explanation:

First, we need to work out the left-hand side.

  • find g(2) → g(2) = 2 - 1 which is 1
  • next, find f(1) → f(1) = 1³ which is 1

Now, we can work out the right hand side.

  • find f(-1) → f(-1) = -1³ which is -1
  • then, find g(-1) → g(-1) = -1 - 1 = -2

Finally we can work out the full sum: 1 + -2 = -1.

Hope this helps!

Suppose that y is inversely proportional to square root of x.
FromTheMoon [43]

Answer:

i) k = 36.8

ii)y = 36.8/square root of x

iii)y = 1.4

Step-by-step explanation:

If y is inversely proportional to square root of x;

then the two variables are related by,

y = k/ square root of x

i)Value of k when...x = 8 and y = 13,

substitute into the equation above..so as to find the value of k

13 = k/square root of 8

;k = 13 × square root of 8

;k = 36.8

ii)Then substitute the value of k with...36.8

y = 36.8/square root of x

iii)If x = 27...then y =;

y = 36.8/27

y = 1.4

I don't know this please help no links Brainliest

The slope-intercept equation is y=mx+b.

The slope formula is \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Our three points are (5,5), (-5,-7) and (0,-1)

Using our slope formula our slope becomes \frac{-7-5}{-5-5} =\frac{12}{10} =\frac{6}{5}

Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, y=\frac{6}{5}x-1. When we solve for x and y, we get -1=0+b, or b=-1.

When we plug that back into the equation, we gety=\frac{6}{5}x-1.

Two consecutive odd negative integers have a product of 483, find the integers ...?
irinina [24]
In order to find this you need to assume that they are declared as X and as X + 2. This makes the formula for calculating it x (x+2)=483, and this, based on the formulas for calculation, equals

 x^2+2x-83=0

From this we can see that a negative X is -23, which when +2 is added results in -21.
