Ask questions in the comment section if you have questions. I'm happy to help! <3

Step-by-step explanation:

What the question is telling you is that x and y and proportional, almost like a ratio.

<h2>x : y</h2><h2>-3 : 6</h2>

Now we have to find y when x is four.

<h2>-3 : 6</h2><h3>     to </h3><h2> 4 : y</h2><h2 />

Let's create a proportional equation...

<h3>(-3 / 6) = 4 / y</h3><h3>- 1 / 2 = 4 / y</h3>

What can we divide by four to create -1/2?

<h2>y = -8.</h2>

kykrilka [37]

Answer:

I think the sides of polygon are 6

Step-by-step explanation:

Because to form a polygon we need to the first to form a horizontal and vertical line,to find the number in that line,and join the line based on the numbers given, then you will get a polygon with 6 side

What value of k makes the statement true?<br> x² (2x³ + 7x²yª) = 2xªyª + 7x³y8?
Nina [5.8K]

By apply the distributive property of multiplication, the value of k which makes the statement true is 1.

<h3>What is the distribution property?</h3>

Mathematically, the distributive property of multiplication is given by tis expression:

x(y + z) = xy + xz.

Next, we would apply the distributive property of multiplication to the given equation by distributing to the left-hand side using xy⁴:

k(2x⁴y⁴ + 7x³y⁸) = 2x⁴y⁴ + 7x³y⁸

Dividing both sides by the common factor, we have:

k = (2x⁴y⁴ + 7x³y⁸)/(2x⁴y⁴ + 7x³y⁸)

k = 1.

In conclusion, the value of k which makes the statement true is 1.

Which of the following is an arithmetic sequence? -7/11 6/11 -5/11 4/11....
Anastasy [175]

Answer:

the right answer is \frac{3}{4} ,-\frac{3}{5},- \frac{3}{6} ,-\frac{3}{7}

Step-by-step explanation:

to find the reason for the sequence, the following formula must be used;

q = t2 / t1

where t2 is equal to the second value of the sequence and t1 to the first value.

q= t2/t1

q = \frac{-\frac{3}{5} }{-\frac{3}{4} } = \frac{12}{15} =\frac{4}{5}

Can u guys help me with these two problems?? for the first one I got 76 ,but I don't think is right.
Elina [12.6K]

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is x.

180 = 44 + 90 + x

180 = 134 + x

x= 46

The angle y of the other triangle plus the angle x of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

90 = x + y

90 = 46 + y

y=44

To find ?, we have

180 = 58 + 44 +?

180 = 58 + 44 +?

? =78

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

180 = x + 50 + 25\\180 = x+ 75\\x=105

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

180 = 36 + 105 + y

180 = 141+ y

y=39

?=39
