Answer:

x = 11

Step-by-step explanation:

3(2x-4) = 5x-1

6x + (-12) = 5x + (-1)

add -12 to both sides, subtract 5x from both sides. Simplify.

x=11

The cost of renting ice skates at a skating rink is $1.25. The rink charges $3.25 for each hour, x, of skating. Which graph best
posledela

Answer:

A

Step-by-step explanation:

Since the total cost at first will not be 5 exactly, it will turn to 4.5 (4.50). And it will be just below the five, at the first hour. And then from there, just add 3.25 each hour and forget about the 1.25 since 1.25 is used for the beginning only, and not the rest.

Let f(x, y) = (x + y)e x 2−y 2 and R be the rectangle enclosed by the lines x − y = 0, x − y = 2, x + y = 0, and x + y = 3.
dalvyx [7]

Answer:

(1/4)*(e⁶ - 7)

Step-by-step explanation:

a) Given

x − y = 0  if  x = 0  ⇒  y = 0

x − y = 2  if  x = 0  ⇒  y = -2;  if  y = 0   ⇒  x = 2

x + y = 0  if  x = 0   ⇒  y = 0

x + y = 3  if  x = 0  ⇒  y = 3;  if  y = 0   ⇒  x = 3

then we show the region R in the pics 1 and 2.

b) We make the change of variables as follows

u = x + y

v= x - y

If

x - y = 0  ⇒ v = 0

x − y = 2  ⇒ v = 2

x + y = 0  ⇒ u = 0

x + y = 3  ⇒ u = 3

Where u is the horizontal axis and v is the vertical axis, the new region S is shown in the pic 3.

c) We evaluate ∫∫R (x + y)*e∧(x² - y²)dA

The procedure is shown in the pic 4, where we have to calculate the Jacobian in order to use it to get the answer.

The three consecutive terms
Studentka2010 [4]

Answer:

<h3>1</h3>

Step-by-step explanation:

The nth term of an exponential sequence is expressed as ar^n-1

The nth term of a linear sequence is expressed as Tn = a + (n-1)d

a is the first term

r is the common ratio

d is the common difference

n is the number of terms

Let the three consecutive terms  of an exponential sequence be a/r, a and ar

second term of a linear sequence = a +d

third term of a linear sequence = a + 2d

sixth term of a linear sequence = a + 5d

Now if the three consecutive terms  of an exponential sequence are  the second third and sixth terms  of a linear sequence, this is expressed as;

a/r = a + d ..... 1

a = a + 2d ..... 2

ar = a+ 5d .... 3

From 2: a = a + 2d

a-a= 2d

0 = 2d

d = 0/2

d = 0

Substitute d = 0 into equation 1:

From 1: a/r = a + d

a/r = a+0

a/r = a

Cross multiply

a = ar

a/a = r

1 = r

Rearrange

r = 1

<em>Hence the common ratio of the exponential sequence is 1</em>
