Answer:

1 1/2

Step-by-step explanation:

-2 1/4 = -\frac{(2*4)+1}{4}= -\frac{9}{4}

-1 1/2 = -\frac{(1*2)+1}{2}=-\frac{3}{2}

-2  1/4 ÷ -1 1/2 = -\frac{9}{4} * -\frac{2}{3}

                      = \frac{3}{2}

                     = 1 1/2

Use KCF method

Keep the first number.

Change division to multiplication

Flip the second number

2x+4y=24<br> -12x+8y=-16
EleoNora [17]
Dividing the first equation by 2
X + 2y = 12
Dividing the equation 2 by 4
-3x + 2y = -4
subtracting both equations
4x = 16
X = 4
Also 4 + 2y = 12
2y = 8
Y = 4

PLEASE HELP!!!!!!!! (ALGEBRA II)
qwelly [4]

Answer:

-4     4     4.5     8     20.5     32

Step-by-step explanation:

f$ \circ  $ g(x) = f(g(x))

Given,   f(x) = 2x²

and       g(x) = x - 2

Now f(g(x)) = f(x - 2) = 2(x - 2)²

We know that (a - b)² = a² - b² + 2ab

Using this we expand f(g(x)). We get:

                        f(g(x)) = 2{x² - 4x + 4}

Similarly,        g(f(x)) = g(2x²) = 2x² - 2

Now, f(g(-2))    = 2[(-2)² - 4(-2) + 4]     = 2(16)                           = 32.

Also, g(f(-2))   = 2[(-2)² - 2]                = 2(2)                             = 4.

f(g(3.5))  = 2{(3.5)² -4(3.5) + 4} = 2[12.25 - 14 + 4] = 2(2.25)    = 4.5.

g(f(3.5))  = 2{(3.5)² -2} = 2{12.25 - 2}                     = 2(10.25)   = 20.5.

f(g(0))     = 2{0 - 4(0) + 4}  = 2(4)                                               =  8.

g(f(0))     = 2{0 - 2}                         = 2(-2)                                 = -4.

Arranging them in ascending order, we get:

-4     4     4.5     8     20.5     32 would be the sequence.

the equation of a line is y=-1/2x+6. Write an equation in point-slope form for the same line. Explain the steps that you used.
Citrus2011 [14]
Y = -1/2x + 6.....the slope is -1/2 and the y int = 6 or (0,6)

y - y1 = m(x - x1)
slope(m) = -1/2
(0,6)....x1 = 0 and y1 = 6
now we sub
y - 6 = -1/2(x - 0) <==

** You basically just label ur variables and sub them into the point slope form
