Answer:

Hello,

answer B

2

Step-by-step explanation:

\dfrac{2}{x} -\dfrac{x}{x+5} =\dfrac{10}{x^2+5x} \\\\we\ suppose\ x\neq 0\ and\ x\neq -5\\\\\text{Reducing to the same denominator}\\\dfrac{2(x+5)-x^2}{x(x+5)} =\dfrac{10}{x^2+5x} \\\\Simplify\ by\ x^2+5x\\\\2x+10-x^2=10\\\\-x^2+2x=0\\\\-x(x-2)=0\\\\roots\ are\ 2 \ and\ 0\ (to\ be\ excluded)\\\\Root=2\\

PLEASE HELP ME!<br> Find m∠FEC.<br><br> Answer Options:<br> A. 69<br> B. 50<br> C. 57<br> D. 37
Anna35 [415]

Answer:

Option (A)

Step-by-step explanation:

Measure of an angle formed between a chord and a secant is equal to the half of the difference of the intercepted arcs.

m(∠FEC) = \frac{1}{2}[m(\text{arc FC})-m(\text{arc})FD]

(15 + 6x)° = \frac{1}{2}[(24x - 6)^{\circ}-(9+7x)^{\circ}]

30 + 12x = (24x - 7x) - (6 + 9)

30 + 12x = 17x - 15

17x - 12x = 30 + 15

5x = 45

x = 9

m(∠FED) = (15 + 6x)

               = 15 + 6(9)  

               = 69°

Option (A) will be the correct option.

Eight times a number plus five times another number is -13 the sum of the two numbers is 1 what are these numbers
m_a_m_a [10]

The two numbers are -6 and 7

<em><u>Solution:</u></em>

Given that eight times a number plus five times another number is -13

The sum of two numbers is 1

To find: the two numbers

Let the two numbers be "a" and "b"

From given information,

Eight times a number plus five times another number = -13

eight times a number "a" + five times another number "b" = -13

8a + 5b = -13 ---- eqn 1

Also given that sum of two numbers is 1

sum of two numbers = 1

a + b = 1 ---- eqn 2

<em><u>Let us solve eqn 1 and eqn 2 to find values of "a" and "b"</u></em>

From eqn 2,

a = 1 - b ----- eqn 3

Substitute eqn 3 in eqn 1

8(1 - b) + 5b = -13

8 - 8b + 5b = -13

8 - 3b = -13

-3b = -13 - 8

-3b = -21

<h3>b = 7</h3>

Substitute b = 7 in eqn 3

a = 1 - 7

<h3>a = -6</h3>

Thus the two numbers are -6 and 7

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
ikadub [295]

Answer:   4095

<u>Step-by-step explanation:</u>

He sold 1 car on the first day so the first term (a) is 1. The amount doubles each month so the ratio (r) is 2.

Input those values into the Sum formula:

S_n=\dfrac{a(1-r^n)}{1-r}\\\\S_{12}=\dfrac{1(1-2^{12})}{1-2}\\\\.\quad=\dfrac{1-4096}{-1}\\\\.\quad=\dfrac{-4095}{-1}\\\\.\quad=4095
