Answer:

When you reflect across the x-axis, the x coordinate stays the same. When you reflect across the y-axis, the x coordinate becomes opposite. When you reflect over the origin, both coordinates become opposite.

Step-by-step explanation:

When you look at the coordinate plane, the x-axis is horizontal (side to side) and the y-axis is vertical (up and down). If you reflect across the x-axis, then you are mirroring (flipping) the object over the horiontal line, which means your x value stays the same. If you reflect across the y-axis, you are mirroring (flipping) the object over the vertical line, which means your y value stays the same and the x value must become opposite. When you cross the origin, you are going diagonal across the coordinate plane, which means both the x and y values will become opposite.

Write the sentence as an equation The product of -2 and -30 gives 60

slega [8]

The equation for the product of -2 and -30 gives 60 is:

$-2 \times -30 = 60$

Solution:

Given that, The product of -2 and -30 gives 60

We have to write the sentence as equation

It includes operations such as addition, subtraction, multiplication and division.

From given statement,

The product of -2 and -30 gives 60

Here, "product" means multiplication

Therefore, -2 multiplied with -30 gives 60

Which is written as equation as,

$-2 \times -30 = 60$

Thus the given sentence is translated into equation

Here are your fill-ins:

r = 1 is a zero, so (r-1) is a factor.

r = -1 is a zero, so (r+1) is a factor.

The remainders from synthetic division are 0 each time.

See the attachment for the synthetic division numbers.

_____

The reduced quadratic is ...

... x² -6x +13 = 0

Solving by completing the square, we have ...

... (x -3)² = -4

... x = 3 ± 2i

_____

The quadratic formula would tell you ...

... x = (-(-6) ± √((-6)² -4(1)(13)))/(2·1) = (6±√-16)/2 = 3±2i
