What is the solution to the equation: 2 ∣ x + 1 ∣ + 3 = 11 ?

Use inverse operations. 11 minus 3 is 8. 8 divided by 2 is 4. 4 minus 1 is 3.

(NOT SURE) x COULD equal 3, but the lines, as far as I know. relate to absolute value. So it could be |-3 + 1| and that would equal 4.

and if you put a variable next to a number, you multiply. so you multiply 2 by 3 plus 1, or 2 times 4, which equals 8. 8 plus 3 equals 11.

there :)

16. What is the measure of ZAOB?
skelet666 [1.2K]
Find angle a2 which is 40 degrees because it is parallel to angle c.

Find the total of d1 and d2.
total of d1 and d2: 180 - 40 - 40 = 100 degrees

Find d1 and d2 separately.
100 divided by 2 = 50 degrees

Use d1 to find b1 to find total of a1 and a2.

b1 is parallel to d1 so b1 = 50 degrees

a1 and a2 = 180 - 50 - 50 = 80 degrees

a1 = 80 divided by 2 = 40

Since a1 and c1 are parallel due to alternate angles, c1 is 40 degrees

Find b2 now which requires you to do total - minus all angles in the triangle with angle b2.

180 - 40 - 50 - 40 = 50 degrees (angle b2)

AOB has b1 and a1.

40 + 50 = 90 degrees (a1 + b1 = AOB)

The answer is 90 degrees

If a crew of 4 workers complete the job in 10 hours, how long will it take 5 workers to complete the same job?
Elanso [62]

Answer:

It will take 8 hours for the 5 workers to complete the same job.

Step-by-step explanation:

The amount of work done is the same for both crews.

Work = time * workers

Work = 10 * 4      


Work = time * 5


Set the two equal

10 * 4 = time * 5

Divide each side of the equation by 5

10*4/5 = time *5/5

8 = time

The graph represents the function f(x) = x2 + 3x + 2.
Bezzdna [24]
For this problem, you have to find the g(x) right?

The f(x) is already given, so all you have to do is multiply both sides by negative 1 (-1) to get the g(x) which is the opposite.

It'll look like this (g(x) = x^2 + 3x + 2)(-1)

Then the answer should be, g(x) = -x^2  - 3x - 2
