Answer:

O = 4 Diamond = 18 Δ = - 5

Step-by-step explanation:

The O is 4 because in clue 2 we see that 3 x 4 = 12

Now we can solve clue 1.

Diamond + 2 = 5 * O

Diamond + 2 = 5 * 4

Diamond + 2 = 20 Subtract 2 from each side

Diamond = 20 - 2

Diamond = 18

And now we can solve clue 3 for the Δ

2 * O = Diamond + 2 * Δ

2 * 4 = 18 + (2 * Δ)

8 = 18 + (2 * Δ) Subtract 18 from both sides.

8 - 18 = (2 * Δ)

- 10 = (2 * Δ) Divide each side by 2

- 10 / 2 = (2 * Δ) / 2 The 2 on the right will cancel

- 10 / 2 = Δ

-5 = Δ

So O = 4 Diamond = 18 Δ = - 5

Which number completes this number sentence? [ ? ] > -6 A.-8 B.-7 C.-6 D.0

Xelga [282]

Answer:

It is 0

Step-by-step explanation:

Unlike the positive side of the number line which increases its value as it goes up in numbers, the negative side of a number line increases its value as it goes goes down in numbers as the more closer a negative number is to the positive side of infinity, the greater value it has. In this instance, zero is the greater number than -6 and all other negative numbers.

Which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4

evablogger [386]

Answer:

$r(x)=(4x)^7$

Step-by-step explanation:

For a horizontal compression, we multiply whole numbers greater than 1 in front of $x$ of the given function.
For horizontal expansion, we multiply by the reciprocal of the number for horizontal compression, in front of $x$ of the function.

For example,

If we wanted to horizontally compress $y=x^2$ , we would multiply by 4 to get $y=(4x)^2$ , and

if we wante to horizontally expand $y=x^2$ , we would multiply by $\frac{1}{4}$ to get $y=(\frac{1}{4}x)^2$

Since this question asks for horizontal compression, we multiply the $x$ of the function by 4. So the function we need is $f(x)=(4x)^7$ . The second choice is correct.
