Jenny’s mother is 5 years older than twice Jenny's age. The sum of their ages is 62 years. This is represented by the equation x

Salsk061 [2.6K]

Answer:

Jenny´s age is 19 and her mother is 43.

Step-by-step explanation:

1. Plug in the first value of the set

41 is different from 62, so Jenny isn´t 12 years old.

2. Plug in the second value of the set

50 is different from 62, so Jenny isn´t 15 years old.

3. Plug in the third value of the set

59 is different from 62, so Jenny isn´t 18 years old.

4. Plug in the fourth value of the set

Therefore Jenny´s 19 years old.

5. Calculate Jenny´s mother age:

As the sum of their ages is 62 ages, we have the following equation

where

x=Jenny´s age

y=Jenny´s mother age

Therefore Jenny's mother age is 43 years old.

40 POINTS!!!!! A submarine descends to 1/6 of its maximum depth. Then it descends another 2/3 of its maximum depth. If it is now

tia_tia [17]

Its max is 780

2/3 + 1/6 = 5/6

650/5=130

650+130=780

Let n = 60! + 55! + 50! the unit digit of n and a number of digits to the left of the units digits are consecutive zeros before

Archy [21]

n=8320987125437793528348710310901843271933297732006335848276356027645952000000000000

So you can see there are 12 zeros before you hit the first non-zero, which is 2.

Which is the graph of g(x) = (0.5)x + 3 – 4? On a coordinate plane, an exponential function decreases in quadrant 2 and has a ho

Mashcka [7]

Answer:

The graph will be an exponential function that crosses the y-axis at about (0, -4).

Step-by-step explanation:

$g(x) = (0.5)^{x + 3} - 4$

That means that when x = 0...

$g(0) = (0.5)^{0 + 3} - 4$

$g(0) = (0.5)^{3} - 4$

$g(0) = 0.125 - 4$

$g(0) = -3.875$

So, the graph will be an exponential function that crosses the y-axis at about (0, -4).

Hope this helps!
