Divide -7.4 by -3.8 and you get 1.947 and then I just rounded to 1.95. So x= 1.95

Answer:

1st quarter := 2488.23

2nd quarter = 1646.50

3rd quarter = 1893.98

4th quarter = 1152.93

Step-by-step explanation:

Forecast demand in the next four quarters

intercept ( a ) = 3116.67 - (- 168.25 * 6.5 ) = 4210.29

Slope ( b ) = ( 219041.15 ) - ( 12 * 6.5 * 3,116.67 ) / 650 - ( 12 * ( 6.5)^2 )

= -24059.11 / 143 = -168.25

Forecast demand = a + bt = 4210.29 + 168.25t

1st quarter := 2488.23

2nd quarter = 1646.50

3rd quarter = 1893.98

4th quarter = 1152.93

1). 5x-3x+7 = 3x-1

2x + 7 = 3x - 1

3x-2x=7+1

x=8

$4r + \frac{2}{4} r + 14 = 5r - \frac{3}{4} r + 1 - 3\\ \\5r-4r-\frac{3}{4} r - \frac{2}{4} r = 14-1+3\\ \\r-\frac{5}{4}r =16\\ \\\frac{4}{4}r-\frac{5}{4}r =16\\ \\-\frac{1}{4}r=16\\ \\ r=-64$

What value of n makes the statement true?<br> 6x^n• 4x^2=24x^6<br> n =

aleksandr82 [10.1K]

Answer:

n =4

Step-by-step explanation:

6x^n• 4x^2=24x^6

Combine like terms

24 x^n *x^2 = 24 x^6

We know that a^b * a^c = a^(b+c)

24 x^(n +2) = 24 x^6

Divide each side by 24

x^(n +2) = x^6

The bases are the same so the exponents are the same

n+2 = 6

Subtract 2

n+2-2 = 6-2

n=4
