Your equation is 14-2x=-32

Step 1- subtract 14 on both sides 
 
then your equation is 2x=-46

Step 2- divide 2 on both sides 
   
then you get x= 23

x=23

Candice spent 5 1/4 hours doing her homework. Her brother, Ronald, spent 1/2 that number of hours doing his homework. How many hours did Ronald spend on his homework?

Answer:  Ronald spent 2\dfrac{5}{8} hours on his homework.

Step-by-step explanation: Given that Candice spent 5\dfrac{1}{4} hours doing her homework. Her brother, Ronald, spent half of that number of hours doing his homework.

We are to find the number of hours that Ronald spent on his homework.

Since Ronald spent half of the time as his brother Candice, so the number of hours that Ronald spent on his homework is given by

H_r=\dfrac{1}{2}\times5\dfrac{1}{4}=\dfrac{1}{2}\times\dfrac{21}{4}=\dfrac{21}{8}=2\dfrac{5}{8}.

Thus, Ronald spent 2\dfrac{5}{8} hours on his homework.

QUESTION POSTED AT 28/01/2020 - 01:05 AM

You are going on a field trip in a school bus. A special detector placed on one of the bus's tires counts the number of rotations completed by the tire during the journey. The tire's diameter is 1 meter, and it made 8000 rotations during the trip. How far did the bus travel? Give an exact answer.

The way tires on wheels work is that when the wheel turns one complete
turn, it moves (forward or backward) by a distance that's the circumference
of the tire.

Now, we know that the circumference of a circle is (π) times the diameter.
The diameter of the tire on this bus is 1 meter.  So its circumference is
(π · 1 meter), and every time it turns once, the bus moves 1 meter down
the road.

If the tire rotated 8,000 times, then the bus moved 8,000π meters,
or 8π kilometers.

THAT's the exact answer.  If you want to know how far that actually is,
then you take some number that's approximately π and multiply it by
8 km.  You can never get an exact answer like that, because you can
never write the exact value of π with digits.

In school, we often use  ' 3.14 ' for π .  If you do that, then the bus
traveled

                   (8 km) x (3.14)  =  25.1 kilometers .

When you do that, you have to remember that it's approximate.
If you want an exact answer, then you have to leave π in the answer.

HELP! I'm stumped. A bag contains 100 marbles: 30 red, 30 blue, 30 green, plus a mix of 10 yellow and orange marbles. To be certain that you have 10 marbles of the same color, what is the minimum number you would need to remove (without looking) from the bag?

Well, consider the unluckiest case: In whatever order, you manage to remove nine of the red marbles, nine of the blue ones, nine of the green and all of the yellow and orange mix. So far, you've removed 37 of the marbles (9+9+9+10 = 37), yet you don't have 10 of any single color. If you remove just one more marble, it will be red, blue, or green, and you will have 10 of the same color. So the answer is 38 marbles.  :)

QUESTION POSTED AT 28/01/2020 - 01:02 AM

Terri is analyzing a circle, y2 + x2 = 36, and a linear function g(x). Will they intersect? y2 + x2 = 36 g(x) graph of the function y squared plus x squared equals 36 x g(x) −4 −4 −2 −2 2 2 Yes, at positive x-coordinates or zero Yes, at negative x-coordinates or zero Yes, at negative and positive x-coordinates or zero No, they will not intersect

Answer:

The graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

Step-by-step explanation:

The equation of circle is given as:

x^2+y^2=36

also the graph of the function g(x) is given by:

We are given a set of values in a table as:

  x         g(x)

−4       −4

 −2        −2

   2          2

Hence, the function g(x) could be computed with the help of slope intercept form of a equation as:

y=mx+c; where m denotes the slope of the line and c denotes the y intercept.

when x=-4 g(x)=y=-4

-4=-4m+c

also when x=-2 then y=g(x)=-2

-2=-2m+c

on solving the above two equations using elimination method we get,

m=1 and c=0

hence, y=g(x)=x

Now we are asked tgo find whether the graph of the circle and g(x) intersect each other or not.

Clearly from the graph we could see that the graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

Let x = the ones digit
Let y = the tens digit

x+2y=12
x=2y
x+y=12 substitute x for 2y to get:
(2y)+y=12 add like terms to get:
3y=12
3y=12 divide both sides by 3 to get:
y=4
x+y=12 substitute y for 4 to get:
x+4=12 subtract 4 from both sides to get:
x=8
so if x=ones
and y=tens
then the answer is 48

That would be C.

20x + 5y = 50

y = -20/5x + 50/5
y = - 4x + 10
now in y = mx + b form. the m represents ur slope and the b represents ur y intercept. So here, u have a slope of -4 and a y intercept of 10.

Since 68% of the sample ranges from the plus minus first standard deviation from the mean, then interval wherein it will occur will be between 53.5% to 60.5%. I got this answer through adding and subtracting one standard deviation (3.5) from the mean (which is 57).

QUESTION POSTED AT 28/01/2020 - 12:09 AM

What are the possible numbers of positive, negative, and complex zeros of f(x) = 3x4 − 5x3 − x2 − 8x + 4? Positive: 2; negative: 2; complex: 4 or 2 or 0 Positive: 1; negative: 3 or 1; complex: 2 or 0 Positive: 3 or 1; negative: 1; complex: 2 or 0 Positive: 2 or 0; negative: 2 or 0; complex: 4 or 2 or 0

Using Descartes' Rule of Signs, we observe whether each consecutive term has a + or - sign:
f(x) = 3x4 − 5x3 − x2 − 8x + 4

Signs are: + - - - +

There are 2 sign changes (from +3 to -5, then from -8 to +4). This means that there are either 2 or 0 positive roots. (We take the number of sign changes, which is 2, and subtract by 2s to get all possible numbers of positive roots.)

For negative roots, we first invert all the odd-powered terms in f(x):

3x4 + 5x3 − x2 + 8x + 4

Signs are: + + - + +
There are 2 sign changes, from +5 to -1, and from -1 to +8. Therefore, there are either 2 or 0 negative roots.
Since the overall degree of f(x) is 4, the total number of roots must sum up to 4. There are either 2 or 0 positive roots, and 2 or 0 negative roots, and everything that remains will be a complex root. The possibilities are:
2 positive, 2 negative, 0 complex
2 positive, 0 negative, 2 complex
0 positive, 2 negative, 2 complex
0 positive, 0 negative, 4 complex.
Therefore we can have either 0, 2, or 4 complex roots.

The correct answer is the last choice.
