It's the third choice. Since the symbol is not greater than or equal to -3 so it must got left..

On the first day after the new moon, 2% of the Moon's surface is illuminated. On the second day, 6% is illuminated. Based on thi

maxonik [38]

Answer:

50%: day 13

100%: day 26

Step-by-step explanation:

We are given two days and the amount of the moon that is illuminated. The two days are points on a straight line.

(1, 0.02), (2, 0.06)

y = mx + b

m = (0.06 - 0.02)/(2 - 1) = 0.04

y = 0.04x + b

0.02 = 0.04(1) + b

b = -0.02

y = 0.04x - 0.02

We want y = 50% = 0.5

0.04x - 0.02 = 0.5

0.04x = 0.52

x = 13

y = 100% = 1

0.04x - 0.02 = 1

0.04x = 1.02

x = 25.5

Match the function with the graph. a. Y=√ x+4 b. Y=√ x-1 c. Y= √ x-1+4 d. Y=√ x+1

Musya8 [376]

Answer:

c. $y = \sqrt{x - 1} + 4\\$

Step-by-step explanation:

The x-1 is there because you can see that the starting point is 1 left from the y axis, and +4 because it starts four points above the x axis.

Which expression is equivalent to (4 + 6i)2?

larisa86 [58]

$\bf \textit{recall that }i^2=-1\\\\
-------------------------------\\\\
(4+6i)^2\implies (4+6i)(4+6i)\implies 16+24i+24i+36i^2
\\\\\\
16+48i+36(-1)\implies 16+48i-36\implies -20+48i$

Solve for x X - 1/2 (8 - x) = x + 3(4 - x) - x A) -32/9 B) -9/32 C) 32/9 D) 9/32

Greeley [361]

Option C

$x = \frac{32}{9}$

Solution:

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

We have to solve for "x"

From given,

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

Solve for brackets

Use distributive property

a(b + c) = ab + ac

Therefore,

$x - 4 + \frac{x}{2} = x + 12 - 3x - x$

Combine the constants

$x + \frac{x}{2} = x - x - 3x + 12 + 4\\\\x + \frac{x}{2} = -3x + 16$

Move the variables to left side of equation

$x + \frac{x}{2} + 3x = 16$

Combine the like terms

$2x + x + 6x = 32\\\\9x = 32\\\\x = \frac{32}{9}$

Thus option C is correct
