Answer:

x=0.6241

Step-by-step explanation:

Square both sides and end up with

75.24+x=75.8641

isolate x

x=75.8641 - 75.24

x=0.6241

The sum of three consecutive even integers is 72. Let x represent the least consecutive integer.

Arlecino [84]

The integers are x, x + 2 and x + 4

x + x + 2 + x + 4 = 72
3x + 6 = 72
3x = 72 - 6 = 66
x = 66/3 = 22

The least consecutive integer is 22
The second consecutive integer is 24
Therefore, the numbers are 22, 24 and 26

a roller skating rink offers a special rate for birthday parties. On the samr day, a party for 10 skaters cost $107 and a party

olga nikolaevna [1]

Answer:

$119

Step-by-step explanation:

Let

x -----> the number of skaters

y -----> the cost for birthday parties

we have the points

(10,107) and (15,137)

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{137-107}{15-10}$

$m=\frac{30}{5}=6\ \frac{\$}{skater}$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=6\\point\ (10,107)$

substitute

$y-107=6(x-10)$

step 3

Convert to slope intercept form

$y-107=6x-60$

$y=6x-60+107$

$y=6x+47$

step 4

How much would a party for 12 skaters cost?

For x=12 skaters

substitute the value of x in the equation and solve for y

$y=6(12)+47$

$y=\$119$

Help me find the answer

labwork [276]

Answer:

f(2) =8

Step-by-step explanation:

f(2) Is when n=2

f(2) = -5 *f(2-1) -7

f(2) = -5 *f(1) -7

We know that f(1) = -3

f(2) = -5 *-3 -7

= 15 -7

= 8
