Fluffy, Spot and Skampy have a combined age in dog years of 91. Spot is 14 years younger than Fluffy. Skampy is 6 years older th

WITCHER [35]

Answer: fluffy = 33yrs

Spot = 19 yrs

Skampy = 39 yrs

Step-by-step explanation:

Let fluffy = x

Spot = y

Skampy =z

x + y + z = 91 -------1

x -14 =y ------2

z = x + 6 --------3

Put eqn 2 and 3 in eqn 1

x + x - 14 + x + 6 = 91

3x = 99

x = 33

y = 33-14= 19

z = 33+6 = 39

Answer: $(-\infty, -4]$

Curved parenthesis at negative infinity

Square bracket at -4

====================================================

Work Shown:

$5(x+4) \le 0 \\\\x+4 \le \frac{0}{5} \\\\x+4 \le 0 \\\\x \le 0-4 \\\\x \le -4 \\\\$

The last inequality shown above is the same as saying $-\infty < x \le -4$

Converting this to interval notation leads to the final answer of $(-\infty , -4]$

Note the use of a square bracket at -4 to include this endpoint. We can never include either infinity, so we always use a parenthesis for either infinity.

On a coordinate plane, triangle A B C is shifted 4 units to the right and 2 units up to form triangle A prime B prime C prime. I

zheka24 [161]

Answer:

(x, y) ⟶ (x + 4, y + 2)

Step-by-step explanation:

If you shift a point four units to the right, x ⟶ x + 4.

If you shift it up two units, y ⟶ y + 2.

If you combine the two shifts into one transformation, the rule becomes

(x, y) ⟶ (x + 4, y + 2)

Tereka and Emma each deposit money in savings accounts. The amount of money, in dollars, in Tereka’s account after x years is mo

Over [174]

Given:

Amount of money in Tereka’s account : $T(x)=472(1.04)^x$

Amount of money in Emma’s account : $E(x)=485(1.09)^x$

To find:

The difference between initial amounts Tereka and Emma deposit.

Solution:

Substitute x=0 in the given functions, to get the initial amount of money they deposit.

$T(0)=472(1.04)^0$

$T(0)=472(1)$

$T(0)=472$

So, the initial amount Tereka deposit is $472.

$E(0)=485(1.09)^0$

$E(0)=485(1)$

$E(0)=485$

So, the initial amount Emma deposit is $485.

Difference between the initial amounts Tereka and Emma deposit is

$485-472=13$

Therefore, the difference between initial amounts Tereka and Emma deposit is $13. Emma deposit $13 more than Tereka.
