The coefficient of xy in the product of (4x^2+2y) and (3x+y^2) is ...
LUCKY_DIMON [66]
Here is your answer! The coefficient of xy is 6. To solve this problem, you need to multiply your two polynomials together. I used the FOIL Method- multiply the First two, the Outside two, the Inside two, and the Last two. You can see how I did it on the picture attached. Next, the answer that you get as a result from FOILing is your polynomial. If you look at the number before xy, that is the coefficient. A coefficient is a number that is right before and attached to a variable. I hope this helps you! :))

Tim earned $300 in five days. After the first day, he earned $10 more each day than the day before. How much did Tim earn on the
Vika [28.1K]
Use the equation 300⇒5x to find how much tim made each day on average. 
x⇒60   so, Day 1: $60, Day 2: $70 etc.. so the equation 300=5x+10 suffices the problem. 300⇒5x+10 ⇒    290=5x
x=58
So, Tim earned $58 his first day. Hope this helped.

I need to find all real values of x from this inequality x^2>2x-2 and also this question x^2>2x+2. I need the answer fast
sergeinik [125]

x^2\gt2x-2

x^2-2x+2\gt0

You are essentially asking at this point where is the quadratic function greater than 0. To get the interval find the roots. Between the roots the function is guaranteed to be LESS THAN zero. Everywhere else the function is greater than 0.

x^2-2x+2=0

Use Vieta's rule to get the roots,

(x-1)(x-1)=0

Both roots are the same so no value is less than 0 which means all values except at the point of root are strictly greater, the point of root is at x_{1,2}=1 which means the set for which the quadratic function is greater than 0 is \mathbb{R}-\{1\} "all real numbers except 1".

To convert this into interval notation use all numbers up to 1 but not including and all numbers after 1 but not including,

(-\infty,1)\cup(1,\infty)

Hope this helps :)

Kaylin bought a soda and two bags of popcorn for $3.00 . HER brother bought three sodas and a bag of popcorn for $6.50
Veseljchak [2.6K]

Answer: price of soda (a) = $2 and price of popcorn (b) = $0.5

Step-by-step explanation:

Let's denote soda = a and popcorn = b

Kaylin bought a soda and two popcorn, writing out an equation for this would be

a + 2b = $3...........equation (i)

And her brother bought 3 sodas and 1 popcorn.

3a + b = $6.50..........equation (ii)

From equation (i),

a + 2b = 3

Making a the subject of formula,

a = 3 - 2b......equation (iii)

Using substitution reaction, put equation (iii) into equation (ii)

3(3 - 2b) + b = $6.50

9 - 6b + b = 6.50

9 - 5b = 6.50

Collecting like terms,

5b = 9 - 6.50

Divide both sides by 5,

b = 5.

Put b = 5 into equation (i)

a + 2(0.5) = 3

a + 1 = 3

a = 2

Therefore, the price of soda is $2 per one and $0.5 for each popcorn.

In the diagrams below, ABC is similar to RST. Use a proportion with sides AB and RS to find the scale factor of ABC to RST. Show
kicyunya [14]

Answer:

The scale factor of triangle ABC to triangle RST is 1/3

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

z ----> the scale factor

To find the scale factor divide the length side of the image (reduced triangle) by the corresponding length side of the pre-image (original triangle)

z=\frac{RS}{AB}

substitute the values

z=\frac{6}{18}

simplify

z=\frac{1}{3}

The scale factor is less than 1

so

Is a reduction
