Answer:

1st Option

Step-by-step explanation:

All angles in a triangle must add up to 180°.

Step 1: Set up equation

40° + 60° + 16x = 180°

Step 2: Rewrite

60° + 16x + 40° = 180°

Answer:

Option: A.

Step-by-step explanation:

Hey there!

In the given triangle;

60° +16x° + 40° = 180° { Sum of interior angle of a triangle}

100° + 16x= 180°

16x = 180° - 100°

$x = \frac{80}{16}$

Therefore, X= 5°.

So, Option A (equation) is used for solving the value of"X".

Hope it helps...

Find the solution using the Quadratic Formula. (show work) 2x + 8x+ 5 = 0 a. 47 ſ6 b. -27 56 c. -2± √3

Answer:

The roots of the equation for the given quadratic equation is $-2\pm \frac{\sqrt{6}}{2}$ .

Step-by-step explanation:

Given quadratic equation as :

2 x² + 8 x + 5 = 0

The roots of the quadratic equation ax² + bx + c = 0 as can be find as :

x = $\frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}$

x = $\frac{-8\pm \sqrt{8^{2}-4\times 2\times 5}}{2\times 2}$

or, x = $\frac{-8\pm \sqrt{64-40}}{4}$

Or, x = $\frac{-8\pm \sqrt{24}}{4}$

Or, x = $\frac{-8\pm 2\sqrt{6}}{4}$

∴ x = $-2\pm \frac{\sqrt{6}}{2}$

Hence The roots of the equation for the given quadratic equation is $-2\pm \frac{\sqrt{6}}{2}$ . Answer

PRE-ALGEBRA HELP PLEASE!

Colt1911 [192]

PART A) the initial value of the function is 150 at 0 weeks, that means that there are still 150 songs to be downloaded at the beginning.
 The rate of change is -30 songs each week, that is because the amount of songs left to be downloaded decrease by 30 each week.

PART B:
 lets use 2 points of the graph p1(0, 150), p2(1, 120)
calculate the slope:
m = (y2- y1)/(x2 - x1) = (120 - 150)/(1 - 0)
m = -30
and now use line equation in form point-slope:
y - y1 = m(x - x1)
y - 150 = -30(x - 0)
y = -30x + 150
