Genrish500 [490]

Answer:

The amount of increase per \frac{1}{3}  hour by $1.

Step-by-step explanation:

Julian charges $10 for every \frac{1}{3} hour he walks a dog.

He increases his fee by 10%

Now we have to find 10% of $10

Amount increased = \frac{10}{100} .10 = 1

So the amount increased by $1.

–2x + 2y = -4<br> 3х + Зу = -18
rodikova [14]

Answer:

(-2, -4)

Step-by-step explanation:

–2x + 2y = -4

3х + Зу = -18

Divide the first equation by 2

–2x/2 + 2y/2 = -4/2

-x +y = -2

Divide the second equation by 3

3х/3 + Зу/3 = -18/3

x + y = -6

Add these equation together

-x +y = -2

x + y = -6

-------------------

0x + 2y = -8

2y = -8

Divide each side by 2

2y/2 = -8/2

y = -4

Now we need x

x+y = -6

x-4 = -6

Add 4 to each side

x-4+4 = -6+4

x = -2

Can someone help me w this question? rq?
victus00 [196]

Answer:

C.

Step-by-step explanation:

We can off-the-bat eliminate choices A and B, because the first part of the quadratic formula is a -b. Therefore, the value for b in the quadratic has to be a positive, because the value in the formula is negative. This leaves us with choices C and D. If you look at the discriminant, you will see that our <em>a </em>in the quadratic formula is 3, so your answer choice is C.
