Answer:

x =2

Step-by-step explanation:

Solve for x:

6 - 4 x = 2 - 2 x

Add 2 x to both sides:

2 x - 4 x + 6 = (2 x - 2 x) + 2

2 x - 2 x = 0:

2 x - 4 x + 6 = 2

2 x - 4 x = -2 x:

-2 x + 6 = 2

Subtract 6 from both sides:

(6 - 6) - 2 x = 2 - 6

6 - 6 = 0:

-2 x = 2 - 6

2 - 6 = -4:

-2 x = -4

Divide both sides of -2 x = -4 by -2:

(-2 x)/(-2) = (-4)/(-2)

(-2)/(-2) = 1:

x = (-4)/(-2)

The gcd of -4 and -2 is -2, so (-4)/(-2) = (-2×2)/(-2×1) = (-2)/(-2)×2 = 2:

Answer: x = 2

Cot y, if csc y =-10/3 and cos y< 0

fredd [130]

$\csc y=-\dfrac{10}3\implies\sin y=-\dfrac3{10}$

$\cos^2y=1-\sin^2y\implies \cos y=\pm\sqrt{1-\dfrac9{100}}=\pm\dfrac{\sqrt{91}}{10}$

You're told that $\cos y$ , so omit the positive root.

$\cot y=\dfrac{\cos y}{\sin y}=\dfrac{-\frac{\sqrt{91}}{10}}{-\frac3{10}}=\dfrac{\sqrt{91}}3$

An amount of $40,000 is borrowed for 11 years at 7 5% interest compounded annually. If the loan is paid in full at the end of th

valina [46]

Amount to be paid back = $ 88,624.36

Step-by-step explanation:

Principal amount = $ 40,000

Rate of interest = 7.5%

Number of years = 11

$A=P\left(1+\frac{r}{n}\right)^{n t}$

Plugin the values as,

$A=40000\left(1+\frac{7.5}{100}\right)^{11}$

$A=40000(1+0.075)^{11}$

$A=40000(1.075)^{11}$

$A=\$ 88,624.36$

What is 1/10th of 2,871,000?

abruzzese [7]

This is fairly simple. Divide 2,871,000 by 10 and that's your answer!

$\frac{2,871,000}{10} =287,100$

Also, since you're dividing by a factor of 10 (or in this case, 10) you can just take away as many places as are zeros in the number you're dividing from. This works for 10, 100, 1,000, 10,000, etc. In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.

9. In the figure below, the area of Square 1 is

Alinara [238K]

Answer:

25 cm^2

Step-by-step explanation:

The side length of square 1 is sqrt(169) = 13

The side length of square 2 is 48/4 = 12

From the Pythagorean Triple 13 - 12 - 5, the side length of square 3 is 5

Finally, 5 * 5 is 25
