Answer:

1) 17

2) 15 because then the associated lines would be coinciding

Step-by-step explanation:

1.) 17

2.)

2x - 4y = 10

3x - 6y = r

Step 1

First lets try to substitute r with 10

and that looks like

*Look at the second image*

And it has No Solution because they are parallel

so we can cross out B and C

Step 2

So lets try to substitute r with 15

and that looks like

*Look at the First image*

It might look like there is only one line but there are actually 2 and they are on top of each other

So that means that they are not parallel but they are coinciding

So we can cross A out and that means the answer is D

Step 3

So the answer is 15 because then the associated lines would be coinciding

Find the solution of the differential equation that satisfies the given initial condition.

andriy [413]

$\displaystyle \frac{dy}{dx} = \frac{x}{y} \ \Rightarrow\ y \,dy = x\, dx\ \Rightarrow\textstyle \ \int y \,dy = \int x\, dx\ \Rightarrow\ \frac{1}{2}y^2 = \frac{1}{2}x^2 + C \Rightarrow \\ \\
y(0) = -3\ \Rightarrow\ \frac{1}{2}(-3)^2 = \frac{1}{2}(0)^2 + C\ \Rightarrow\ C = \frac{9}{2},\\ \\
 \text{so } \frac{1}{2}y^2 = \frac{1}{2}x^2 + \frac{9}{2}\ \Rightarrow\ y^2 = x^2 + 9 \ \Rightarrow \ \\ \\
y = -\sqrt{x^2 + 9}\ \text{ since $y(0) = -3 \ \textless \ 0$}$

m_a_m_a [10]

Answer:

2t + n + 3d = 65

3t + 2n + 5d = 85

t + n + td = 40

Step-by-step explanation:

tubs of popcorn = t

plates of nachos = n

drinks = d

The Smiths: 2t + n + 3d = 65

The Langes: 3t + 2n + 5d = 85

The Radfords: t + n + td = 40

So, the correct answer would be the one including all 3 of these equations. :)

Store A sells a watch for $50 and offers a 5% discount Store B sells the same watch for $60 and offers a 20% discount. From whic

erastova [34]

Answer:

You should buy the watch from Store A because it's cheaper

Step-by-step explanation:

Store A sells a watch for $50 with a 5% discount.

Let's calculate the sale price. The 5% discount is

5/100*$50 = $2.50

The sale price is $50 - $2.50 = $47.50

Now for Store B. The price of the watch was $60 with a 20% discount.

Calculate 20% of $60:

20/100*$60 = $12

The sale price is $60 - $12 = $48

Thus, you should buy the watch from Store A because it's cheaper
