Answer:

See explanation below

Step-by-step explanation:

Find the value of x in each of the following

1) x-1+5√x-1+3=0

5√x-1 = -x -2

Square both sides

25(x-1) = (-x-2)^2

25(x-1) = x^2+4x + 4

25x-25 = x^2+4x + 4

x^2 +4x + 4 - 25x + 25 = 0

x^2 - 21x + 29 = 0

x = 21±√21²-4(29)/2

x = 21±√441-116/2

x = 21±√325/2

x = 21±18.03/2

x = 21+18.03/2 and 21-18.03/2

x = 19.515 and 1.485

4)  x^4-64=0

x^4 = 64

x = \sqrt[4]{64}

x = 2.83

. (06.03 LC) What is the coefficient of y in the expression 2 ⋅ 4 + 3y? (1 point) 2 3 7 8
masya89 [10]

Coefficient of y = 3

Solution:

Given expression is 2 · 4 + 3y.

To find the coefficient of y:

Coefficient means the number in front of the variable or term.

Here, the number in front of y is 3.

2 and 4 are not in front of y, they are separate term.

So, Coefficient of y = 3.

Hence the coefficient of y in the expression 2 · 4 + 3y is 3.

Help me on this problem please
Ivan

You want the equation for a line that goes through the data points (0, 248) and (5, 277). The slope is ∆y/∆x = (277-248)/(5-0) = 29/5 = 5.8. The first data point is the y-intercept, so your equation in slope-intercept form is

... y = 5.8x + 248 . . . . . . where y is MWh of generation and x is years since 2007.

_____

∆y is read "delta y". It means "the change in y".
