143 / 6x+12 = 132 / 72
143 / 6x+12 = 11 / 6

crossmultiply:
66x + 132 = 858
66x = 726
x = 11

Find two consecutive odd integers whose product is 99

Illusion [34]

Let x be the first odd number.

Second odd number will be x+2

Proof:

If 3 (was) the first odd number, 3+2 would be the next which is 5.

So,

(x) (x+2) = 99
xsquare + 2x = 99
xsquare +2x - 99 = 0
xsquare +11x - 9x -99 = 0
x(x +11) -9(x + 11) = 0
(x+11) (x-9) = 0

So the two odd numbers were 9 and 11

Can you deposit 1750 into investment account that will produce 6.05% annual interest the money was left in the car for two years

PSYCHO15rus [73]

Step-by-step explanation:

Find out how much you get money from the annual interest:

100% = 1750

1% = 1750 ÷ 100 = 17.5

6.05% = 17.5 x 6.05 = 105.87

Find out how much you get from interest in 2 years.

105.87 x 2 = 211.74

What is the inverse of the function f(x) = 4x + 8?

Viktor [21]

Answer: FIRST OPTION.

Step-by-step explanation:

Given the following function:

$f(x)= 4x + 8$

Follow this steps in order to find its inverse:

1. Rewrite the function with $y=f(x)$ :

$y= 4x + 8$

2. Solve for "x":

$y-8= 4x\\\\x=\frac{y-8}{4}\\\\x=\frac{y}{4}-2$

3. Now you must exchange the variables:

$y=\frac{x}{4}-2$

4. And finally, rewrite the function with $h(x)=y$ :

$h(x)=\frac{x}{4}-2$

Therefore, the inverse function is $h(x)=\frac{x}{4}-2$

Maria works in a factory that produces new cars. She is having trouble with one of the machines. In order to work properly, the

Dovator [93]

Answer:

Maria did her job properly. Both gears are perpendicular.

Step-by-step explanation:

Recall that given vectors a and b, they are perpendicular if and only if $a\cdot b$ =0. If $a=(a_1,a_2),b=(b_1,b_2)$ . Then $a\cdot b = a_1b1_+a_2b_2$ .

IN our case a=(5,-1,2) and b) (1,-3,-4). So,

$a\cdot b = 5\cdot 1 + (-1)\cdot(-3) + 2\cdot(-4) = 5+3-8 =0$

So both gears are perpendicular.
