We have the following system of linear equation:

(1) x+6y=29
(2) 2x-4y=-6

Let's apply elimination method by multiplying (1) by -2, then:

-2(x+6y)=-2(29)
∴ -2x-12y = -58

Next let's subtract (1) and (2):

(1) -2x-12y = -58
(2) 2x-4y=-6
_______________________
-16y=-64
∴ y=4

Finally, substituting this value in (1) we have that:

x+6(4)=29
∴ \boxed{x=5}

Use the change of variables s=x+3y, t=y to find the area of the ellipse x2+6xy+10y2≤1.
MArishka [77]

t=y\implies s=x+3t\implies x=s-3t

Then

x^2+6xy+10y^2=(s-3t)^2+6(s-3t)t+10t^2=s^2+t^2\le1

which is a disk of radius 1, hence with area \pi.

Who can help me on my math I’m failing can y’all please help me on some questions.
Gemiola [76]

Answer:

7 quarters, 8 nickels

Step-by-step explanation:

So the system of equations you have is:

x + y = 15

0.25x + 0.05y = 2.15

Here's how to solve:

first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:

25x + 5y = 215

Then, you can divide both sides by 5 to simplify it more:

5x + y = 43

Now, you have the system of equations:

5x + y = 43

x + y = 15

Now subtract the two equations:

4x = 28

divide both sides by 4

x = 7

plug x = 7 into the equation x + y = 15 to solve for y:

7 + y = 15

subtract 7 from both sides

y = 8

So you know that there are 7 quarters and 8 nickels.

Mandy is trying to subtract 4 - 12, and she has asked you for help. How would you explain the process of solving the problem to
mojhsa [17]
To solve 4-12 on a number line you would need to start on 4 then move 12 places to the left since 12 is negative. Twelve would be negative because you cant take away 12 from 4 . When you move 12 places to the left you would get -8
