Answer: x = -0.3

Step-by-step explanation:

Given expression

1 - 3 (9x + 3) = 3x + 1

Expand parentheses and apply the distributive property

1 - 27x - 9 = 3x + 1

Combine like terms

(1 - 9) - 27x = 3x + 1

-8 - 27x = 3x + 1

Subtract 3x on both sides

-8 - 27x - 3x = 3x + 1 - 3x

-8 - 30x = 1

Add 8 on both sides

-8 - 30x + 8 = 1 + 8

-30x = 9

Divide - 30 on both sides

(-30)x / (-30) = 9 / (-30)

(-30)x / (-30) = 3 / (-10)

$\boxed{x=-0.3}$

Hope this helps!! :)

Cos (A+B) =1/5 COS (A-B) = 3/5 Then find tan (A-B)

Soloha48 [4]

Answer:

tan (A-B) = ± 4/3

Step-by-step explanation:

COS (A-B) = 3/5

COS² (A-B) = (3/5)² = 9/25 = 1 - sin² (A-B)

sin² (A-B) = 1 - 9/25 = 16/25

sin (A-B) = ± 4/5

tan (A-B) = sin (A-B) / cos (A-B) = (± 4/5) / (3/5) = ± 4/3

11 9/10 First you have to add 10 3/5 and 12 1/2. You get 22 11/10. That is an improper fraction. There are one 10 in 11. So you add 1 1/10 to 22. You get 23 1/10. Now you have to subtract 23 1/10 and 35. You get 11 9/10

Answer:

Step-by-step explanation:

Maybe you want to evaluate ...

16 - 14 ÷ 2 + (3 +2)²

The parentheses are evaluated first.

16 -14÷2 +5²

Then the exponential term.

16 -14÷2 +25

The division is evaluated next.

16 -7 +25

Finally, the sum is evaluated.

= 9 +25

= 34

Short-term classes: Does taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student’s likelihood of

NemiM [27]

Answer:

Option b

Step-by-step explanation:

Given that For a particular course, the pass rate for the 16-week format is 59%. A team of faculty examine student data from 40 randomly selected accelerated classes and determine that the pass rate is 78%.

we have to find whether taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student’s likelihood of passing the course

Since pass rate for 16 weeks is 59% we check whether for 8 weeks is more than this.

So correct null and alternative hypotheses for this research question

would be:

b.H0: p = 0.59; Ha: p > 0.59

Option b is right.

Needing help with some of my college summer HW

Arte-miy333 [17]

B. Half the speed of the car. and C. The number of different colors on the page.

Variables are symbols for unknown values, so you have to find the statements that contain an unknown value.

A. 27 ⇒ The point value is known, so there is no variable.

B. $\frac{1}{2}$ X ⇒ Since the speed of the car is unknown, the variable X represents the speed of the car. This variable is multiplied by $\frac{1}{2}$ or divided by 2 to get half the speed of the car.

C. X ⇒ The number of different colors is not known, so the variable X represents the number of different colors.

D. 80 ⇒ There is nothing unknown in the statement.
