Answer: 9

Step-by-step explanation:

First divide both sides by 3

$a^2=9$

Then root both sides( $\sqrt{a^2}=\sqrt{9}$ )

a = 9

Answer:

$a = 3$

Step-by-step explanation:

$3 {a}^{2} = 27 \\ \frac{3 {a}^{2} }{3} = \frac{27}{3} \\ {a}^{2} = 9 \\ a = \sqrt{9} \\ a = 3$

Thepotemich [5.8K]

Answer:

The given statement is False statement

Explanation:

We are given that Jaime has blown out a number of candles equal to his age on each of his birthday till now and he is 9 years old now so the total number of candles blown by him all his life is given by the

arithmetic series

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 and

not the arithmetic series

0 + 1 + 2 + 3+ 4+ 5+ 6+ 7+ 9 as given

so the given statement is false.

My son, Garrett, is 11 years old and has a piggy bank that he wants to fill. He started with 5 one dollar bills. Every Saturday

Debora [2.8K]

Answer:

1) M(x) = 5 + 3x

2) Dependent variable; 3 dollar bills

Independent variable: chores

3) Range is continuous

Domain is discrete

4) Range: 0 ≤ x ≤ 10

Domain: 5 ≤ M ≤ 35

Step-by-step explanation:

We are told he started with 5 number of $1 dollar bills and that every Saturday, he earns 3 more $1 dollar bill.

Thus, total number of $1 bills earned after x number of Saturdays(weekly) is;

M(x) = 5 + 3x

After 10 weeks, total number is;

M(10) = 5 + 3(10)

M(10) = 35

The dependent variable is the 3 more dollar bills earned each Saturday because it depends on chores he completed. While the independent variable is the chores because it doesn't depend on anything.

After 10 weeks, the range and domain will be;

Range: 0 ≤ x ≤ 10

For the; Domain:

For x = 1, M(0) = 5 + 3(0) = 5

M(10) = 35

Thus;

Domain: 5 ≤ M ≤ 35

The range could be all numbers in the interval from 0 to 10. Thus, it is continuous.

Whereas, the domain doesn't contain all the numbers in the interval from 5 to 35. Thus it is Discrete.

enyata [817]

Answer:

$\text{A. }y=1.30x+1.50$

Step-by-step explanation:

The two ringtones will cost her a total of $0.75\cdot 2=1.50$ and is a fixed amount. The relationship between the cost and number of songs only is $y=1.30x$ and therefore the answer is $\boxed{\text{A. }y=1.30x+1.50}$ . You can also directly find the answer by finding the y-intercept (in this case $1.50$ ), as no other answer choices include the term $1.50$ , so A must be the correct answer.
