Answer:

see below

Step-by-step explanation:

The student put 5 in for y and 1 in for x. It should be x=5 and y =1

y = 3x+2

1 = 3*5 +2

1 = 15+2

1 = 17

This is not true so this is not a solution

4. 1 less than twice the square of a number

givi [52]

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D

Two boats are traveling toward a cliff that is 225 feet above sea level. When the two boats are exactly 200 feet apart, the boat

timofeeve [1]

Answer:

$x=23.82^o$

Step-by-step explanation:

$Solve ~for~x, first ~ we~ need ~ to ~know~y$

$tan~36=\frac{225}{y}$

$y=\frac{225}{tan ~36}$

$y=309.6859321$

$tan(x)=\frac{225}{y+200}$

$x=tan^{-1}(\frac{225}{309.6858321}$

$x=23.81898048$

$x=23.82^o$

hope it helps...

The black figure is an ellipse, and the black line segment is its major axis. What is the length of the blue line segment?

andrezito [222]

The answer is: A. 20.3

The explanation is shown below:

1. By definition, the sum of the length of the strings (The length of the blue segment and the length of the red segment) is equal to the length of the major axis (The black segment).

2. Based on this, you can write the following expression, where $x$ is the length of the blue segment:

$x+10.7=31$

3. Now, you must solve for $x$ , as following:

$x=31-10.7$

$x=20.3$

4. Therefore, the answer is the option A.
