Answer:

C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a = 3.

Step-by-step explanation:

Given the points (5, 15) and (-5, -15) are plotted using the equation y = a•x, this shows a proportional relationship between y and x.

Thus using any of the points, say (5, 15), x = 5, and y = 15, thus:

a = y/x = 15/5

a = 3

Therefore, the value of a, which is 3, is the number that the x-values, 5 and -5, are multiplied by to get the corresponding y-values, 15 and -15.

As we can see, if we multiply each of the x-values by 3, it will give us their corresponding y-values.

Use the properties of exponents to determine the value of aa for the equation:
Phantasy [73]

Answer:  a = -2/3

Step-by-step explanation:

Let's start by multiplying both sides by x to simplify:

$4^{1/3} = x^a \times x$

$4^{1/3} = \underbrace{x \times x \times x \times \cdots \times x}_{a\ \textrm{times}} \times \,x$

$4^{1/3} = \underbrace{x \times x \times x \times \cdots \times x \times x}_{a+1\ \textrm{times}}$

4^{1/3} = x^{a+1}

Looking only at the exponents, it seems like 1/3 = a+1, so a = \boxed{-2/3}.

Aliyah $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?
MaRussiya [10]
Each pencil cost $2.

Explanation: She had $24 before buying the pencils and after she had $10. 24-10=14 so the total she spent on pencils was $14. She bought 7 pencils so you divide 14 by 7 (14/7=2) which equals 2. So each pencil cost $2.

Vikentia [17]

Answer:

3x^2 + 3  -->  6, 15, 30, 51

2x^2 - 1    -->  1, 7, 17, 31

x^2 + 2     -->  3, 6, 11, 18

Step-by-step explanation:

Let's start with the first equation; 3x^2 + 3

Substitute 1 (the first digit in a sequence) for x.

3(1^2) + 3

3(1) + 3

3 + 3 = <u>6</u>

3(2^2) + 3 Then the second digit.

3(4) + 3

12 + 3 = <u>15</u>

Since the two numbers we have so far are 6 and 15, there is only one sequence this could match. 6, 15, 30, 51.

2(1^2) - 1

2(1) - 1

2 - 1 = <u>1</u>

This equation represents 1, 7, 17, 31.

These same steps apply to the other equation as well.

1^2 + 2, then 2^2 + 2, then 2^2 + 2, and so on. (But we don't need to do extra work to figure that out.)
