\bf log_4\left( \cfrac{\sqrt{x^5y^7}}{zw^4} \right)\implies log_4(\sqrt{x^5y^7})-log_4(zw^4)
\\\\\\
log_4\left[(x^5y^7)^{^\frac{1}{2}}\right]-log_4(zw^4)\implies

Complete the table of inputs for the given function.
Alecsey [184]

Answer:

a. x = \frac{3}{8}

b. g(0) = 3

c. x = 1

d. g(3) = -21

Step-by-step explanation:

Given

g(x) = 3 - 8x

Solving (a): When g(x) = 0

Substitute 0 for g(x)

g(x) = 3 - 8x

0 = 3 - 8x

Solve for 8x

8x = 3

Solve for x

x = \frac{3}{8}

Solving (b): when x = 0

Substitute 0 for x

g(x) = 3 - 8x

g(0) = 3 - 8 * 0

g(0) = 3 - 0

g(0) = 3

Solving (c): When g(x) = -5

Substitute -5 for g(x)

g(x) = 3 - 8x

-5 = 3 - 8x

Solve for 8x

8x = 3 + 5

8x = 8

Solve for x

x = \frac{8}{8}

x = 1

Solving (d): When x = 3

Substitute 3 for x

g(x) = 3 - 8x

g(3) = 3 - 8 * 3

g(3) = 3 - 24

g(3) = -21

(3,51)(5,59)
slope = (59 - 51) / (5 - 3) = 8/2 = 4

y = mx + b
slope(m) = 4
(3,51)...x = 3 and y = 51
sub and find b, the y int
51 = 4(3) + b
51 = 12 + b
51 - 12 = b
39 = b

so ur equation is : y = 4x + 39...but u need it in standard form

y = 4x + 39
-4x + y = 39
4x - y = -39 <==== this is ur equation...x = number of hrs and y = total velocity
====================
ur x axis is the number of hrs
ur y axis is total velocity in km

y = 4x + 39......slope = 4.....y int = (0,39)....x int is (- 9.75,0) or -9 3/4 for graphing purposes)....so start at (-9.75,0)...and since the slope is 4, go up 4 and to the right 1....plot that...then up 4 and to the right 1...plot that...u will cross the y axis at (0,39)....and just connect ur plotted points and u have ur line......or what u can do since it is asking for the first 6 hrs....sub in 1 for x and solve for y....then sub in 2 for x and solve for y...keep doing this up till 6 and u will have ur line up till 6 hrs
