1/2(x+1)=2 which does a possible four-step process to find the solution of this equation

2 answers:

8 0

First you would distribute, 1/2 * x and 1/2 * 1. So you would end up with (1/2x+1/2)=2. Then you would subtract 1/2 from 2, and you would be left with (1/2x)=1 1/2. Then you would divide 1 1/2 by 1/2. You would then be left with x=3. The last step would be to plug in your answer and make sure it's correct.

Solve by completing the square x squared +14x - 51=0

Nesterboy [21]

$x^2 +14x - 51=0\\ \\\Delta = b^{2}-4ac =14^{2}-4*1*(-51)=196+204=400 \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{-14- \sqrt{400}}{2}=\frac{-14-20}{2}= \frac{-34}{2}=-17\\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{-14+ \sqrt{400}}{2}=\frac{-14+20}{2}= \frac{6}{2}=3$

Anyone please HELP cause I’m getting frustrated

pashok25 [27]

Answer:

U =35.5

Step-by-step explanation:

Since this is a right angle, we can use trig functions

tan theta = opp/ adj

tan U = 5/7

Take the inverse of each side

tan ^-1 tan U = tan ^-1 (5/7)

U = 35.53767779

Round to the nearest tenth

U =35.5

madam [21]

To translate 5 units left, add 5 to every x to move up 10 units, add 10 to whole equaiotn example y=2x+2 move left 5 y=2(x+5)+2 move up 10 y=2(x+5)+2+10

the position of a deep sea probe is -2 3/4 fathoms relative to the sea level. after finishing taking data, it moves to -2 5/8 fa

alisha [4.7K]

Answer:

The first mission

Step-by-step explanation:

The depth readings are

The first mission: - 2 3/4 fathoms
The second mission: - 2 5/8 fathoms

Comparing the readings

- 2 3/4 = - 2 6/8 and - 2 5/8

Absolute values compared

2 6/8 > 2 5/8

Indicating the greater value on the first mission

As per above, the first mission was deeper
