Answer:  There is no graph that I can see.  I created one showing each line.  

Step-by-step explanation:  A straight line has the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x is zero).  The two lines with slope 25 will rise much more quickly than the ones with a slope of 5.  You could eliminate two lines based on that alone.  With the two remaining lines, look at the y-intercept seen on the graph (the value of y when x=0).  The options are 5 and -5.  The correct line will be the one with the expected intercept.

Answer:

x=1     y=3

Step-by-step explanation:

x+5y=16

x+3y=10

2y=6

y=3

x+15=16

x=1

verify

1+9=10

Answer:

x = 1 , y = 3

Step-by-step explanation:

x + 5y = 16 → (1)

x + 3y = 10 → (2)

Subtract (1) from (2) term by term to eliminate x

0 + 2y = 6

2y = 6 ( divide both sides by 2 )

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

x + 5(3) = 16

x + 15 = 16 ( subtract 15 from both sides )

x = 1

if it pasts the vertical line check

Step-by-step explanation:

so if there are 2 dots on the same line of a graph it's not a function. or if it's based on x's and y's there can not me x's that are the same number. they can't repeat but y's can!

Answer:

D. [tex]-\frac{\sqrt{2} }{2}[/tex]

Step-by-step explanation:

So, on a regular coordinate plane, coordinates are written (x,y)

well, in trig, coordinates are written (cosθ, sinθ).

if sinθ=[tex]\frac{\sqrt{2} }{2}[/tex] in the second quadrant, then look for the "y-value" that says

if you don't have a unit circle to look at, then it helps to know that the fraction [tex]\frac{\sqrt{2} }{2}[/tex] is ONLY found with ITSELF OR THE NEGATIVE OF ITSELF. it is never paired with another number.

this means that this number will only be seen in the coordinates

[tex](\frac{\sqrt{2} }{2} ,\frac{\sqrt{2} }{2})\\(-\frac{\sqrt{2} }{2},\frac{\sqrt{2} }{2})\\(-\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})\\(\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})[/tex]

use this knowledge along with knowing the signs in each quadrant:

Q1: (+,+)

Q2: (–,+)

Q3: (–,–)

Q4: (+,–)

Answer:

=4/15

=0.26

Step-by-step explanation:

Answer:

x = 4/15

Step-by-step explanation:

Step 1: Multiply both sides by x.

Step 2: Divide both sides by 45.

Therefore, x = 4/15.

Answer:

y = 2/3

Step-by-step explanation:

so 12y-3=5, add the 3 to the 5 to get 12y=8. Then divide the 12y by 12 and the 8 by 12. In so you geet y=2/3

Answer:

y is equal to 2 thirds (y = 2/3)

Step-by-step explanation:

12y − 3 = 5

Substitute the given options to see which one will provide a true statement:

If y = 2:

12y − 3 = 5

12(2) − 3 = 5

24 − 3 = 5

21  = 5  (False statement, so it's not the right answer).

If y = 1:

12(1) − 3 = 5

12− 3 = 5

9 = 5  (False statement).

If y = 2/3:

12(2/3) − 3 = 5

8 - 3 = 5

5 = 5 (True statement).

If y = 13:

12(13) − 3 = 5

156 - 3 = 5

153 = 5 (False statement).

Therefore, the correct answer is: y = 2/3.

Step-by-step explanation:

x, y are the 2 numbers.

x/y = 9/11

x - y = 6

x = y + 6

now we use that in the first equation

(y + 6)/y = 9/11

y + 6 = 9y/11

11y + 66 = 9y

2y = -66

y = -33

x = y + 6 = -27

but the second equation could also be

y - x = 6

then

x = y - 6

and that in the first equation leads to

(y - 6)/y = 9/11

y - 6 = 9y/11

11y - 66 = 9y

2y = 66

y = 33

x = y - 6 = 27

Step-by-step explanation:

Given the linear function, w(x) = 3/5x + 2, where the slope, m = 3/5, and the y-intercept is (0, 2).

Start by plotting the y-intercept on the graph. Then, use your slope, m = 3/5 (rise 3 units, run 5 units) to plot other points on the graph.  

Attached is an edited screenshot of your given problem, which shows the plotted points on the graph using the techniques explained in this post.

Answer:

I don't know if you have given the full question.

Step-by-step explanation:

but from what you have typed I understood that ( -x ) = - ( x)

positive × positive = positive

negative × negative = positive

positive × negative = negative

so from this we derive -x = -x ( when we open the bracket negative 1 is multiplied to x)

Answer:

it is solved at jemrare dot com

Step-by-step explanation:

This problem can be solved using distance formula;

s=vt

Here we suppose;

Speed of Tourists=v1=4 km/h

speed of bus=v2=60km/h

Total time to be taken by the tourists to reach the camp without bus=t

Time taken by tourists when bus used=t-2h20min=t-140min

let the total distance is ‘x’ but half is travelled without bus and other half by bus!

for first half distance=s1 =x/2

for second half distance=s2=x/2

Using s=vt formula for first half;

Answer:

Should be D.

Step-by-step explanation:

Because you can't factor the equation you use the quadratic formula. By using it you should get 4 plus or minus the square root of -4 all over 2. Simplified would be 2 plus or minus i

The correct answer is: 28 children and 122 adults

Answer Wen is incorrect. The reason being is that the function does not continue in both directions from the origin. Since we cannot have a negative value of people, we cannot use all values of x as inputs in the equation. Therefore, it is not continuous.
