Assuming you are asking

does -2x+y=6 and y-2x=4 have a solution

look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values

there is no solution
these 2 lines are paralell

NO SOLUTION

A quadrilateral has angles that measure 74°, 93°, and 117°.

Tamiku [17]

We know the sum of all the angles in a quadilateral is equal to 360. so,
it would be: 360 - (74+93+117)

= 360 - 284
= 76 degrees

So, Your final answer is 76 degrees.

Hope this helps!

Write a quadratic equation with roots of 3/4 and -4

Vaselesa [24]

A quadratic equation given roots is solved by using the relation

${x}^{2} - (sum \: of \: roots)x + product \: of \: roots$

from the question,

sum of the root will be

$\frac{3}{4} + ( - 4) = \frac{3}{4} - 4$

$= \frac{3 - 16}{4}$

$= \frac{ - 13}{4}$

and also, product of the roots will

be

$\frac{3}{4} \times ( - 4) = - 3$

now substituting the sum of roots and product of roots into the equation

${x}^{2} - ( - \frac{13}{4} )x - 3$

$= {x}^{2} + \frac{13}{4} x - 3$

as the quadratic equation for the root 3/4 and -4

Please HELP ASAP!!! The dot plot show the number of hours teenagers spent on two different websites last week. Which statement i

Delvig [45]

Answer:

(F.) the mode of the data for website K is greater than the mode of the data from website L

Step-by-step explanation:

Mode simply means the parameter that occurs the most.

In website K, the one that occurs the most is 8 hours while in website L, the one that occurs the most is 2 hours.

This means that mode of website K is greater than that of website L.

Thus,statement F is correct

Range is the difference between the highest value and the lowest value..

For website K, Range = 14 - 1 = 13

For website L, Range = 13 - 1 = 12

Thus,range of both websites are not the same and as such statement G is wrong.

For a symmetrical distribution, the left and right hand sides of the centre value line of the distribution have to mirror each other.

In this case neither website K nor L have that. Thus, statement H is not correct.

Skewed to the left means that more o

dot points are found to the left of the graph.

For website L, more dot points are located to the left while for website K, it's not the case. Thus, statement J is not correct
