copy and complete the table for the equation x^2 3x-2. Create a graph to estimate the solutions for the equation x^2 3x-2=0

Answers

Answer 1

Answer:

Answer:

Unfortunately, I can't see the table so I can't help you there :(

But to create a graph:

We can just plug in different points and connect them! Remember, the squared makes it a parabola, so your graph should have a similar U-shaped look. If you want to see the solutions in the graph, just look for places where y=0, or where there's a point on the x-axis.

What is the value of x in the equation (x + 12) = (x + 14) – 3?

Answers

Answer: There is NO value of 'x' in the given equation.

Step-by-step explanation: We are given to find the value of 'x' in the equation below:

$(x+12)=(x+14)-3~~~~~~~~~~~~~~~~~~~~(i)$

Finding the value of 'x' in equation (i) means to find the value of 'x' for which the equation is TRUE.

The solution is as follows:

$(x+12)=(x+14)-3\n\n\Rightarrow x+12=x+14-3\n\n\Rightarrow x+12=x+11\n\n\Rightarrow x-x=11-12\n\n\Rightarrow 0=-1,$

which can NEVER be true.

So, the given equation has NO solution.

Thus, there is NO value of 'x' in the given equation.

(x + 12) = (x + 14) - 3

subtract 12 from each side

x = x + 14 - 3 - 12

Now if we subtract x from each side we see that x - x = 0. Combine the terms left over and we have -1, so

0 = -1

The answer is NO SOLUTION

If the first term in an arithmetic sequence is 15 and the tenth term is 69. What is the fourth term in the sequence?

Answers

Hello,

$a_(0)=15$ first term
$a_(1)=15+r$ second term
$a_(2)=15+2r$ third term
...
$a_(9)=15+9r$ is the tenth term =69

15+9r=69
==>9r=69-15
==>r=54/9=6
$a_(3)=15+3r=15+18=33$

The hour hand of a clock moves from 3 to 8 o'clock through how many degrees does it move

Answers

The number of degrees does it move is 150 degrees.

The following things should be considered:

Since there are 12 parts.
Each one should we 30 degrees i.e. $= 360/ 30$
Now 8 - 3 = 5
So, the angle should be $= 5* 30$ = 150 degrees.

Therefore we can conclude that The number of degrees does it move is 150 degrees.

There is a picture.
There 12 parts. Each one is 360/12=30°.
8-3=5 we have.
So, the angle will be 5*30=150°.

A boat takes 8 hours to go 6 miles upstream and come back to the starting point. If the speed of the boat is 4 miles per hour in still water, what is the rate of the current? Hint: total time taken = time taken to go upstream + time taken to go downstream

Answers

Let x = velocity of the water current t1 = time taken to go downstream t2 = time taken to go upstream t1 + t2 = 8 t2 = 8 – t1 v = D/t Downstream (4 + x) = 6/ t1 t1 = 6/(4+x) Upstream (4 – x) = 6/t2 Substitute expression for t2 to obtain (4 – x) = 6/ (8-t1) Substituting the expression of t1 to make a single variable equation, obtaining 6 = (4-x)*(8 – 6/(4+x)) Solving for x, x= 3.16 m/s
