Okay (-6,3) is dog one. Remember that. And (-6,-3) shows the position of the two dogs at the park. Both dogs positions are reflected across the Y-axis. But they are a little different from each other, the dogs of course. So the y-axis is the same but going across the x-axis is different. I know the answer to this question and it’s actually really easy. The answer would be (0,0). The reason for this is, is because two things can’t reflect across the y-axis, and x-axis at the same time. It’s a trick question. Brainliest?

A 37 inch tv sells for $400. This is a $45 less than five times the cost of a 19 inch tv. Find the cost of the 19 inch tv.

adell [148]

Answer:

A 19 inch tv cost $89

Step-by-step explanation:

37 inch tv : 400 = 5x - 45

19 inch tv : x

We have the equation:

5x - 45 = 400

5x = 445

x = 89

Prove: Quadrilateral ABCD is a parallelogram.

Brilliant_brown [7]

Answer:

Step 3.

m∠ AEB = m∠ CED .........By Vertical Angles Theorem.

Step-by-step explanation:

Vertical Angles Theorem:

Vertical angle theorem states that vertical angles, angles that are opposite each other and formed by two intersecting lines,are congruent.

If two lines intersect each other we have two pair of vertical opposite angles. As shown in the figure.

Here,

∠ 1 and ∠ 2 are vertical opposite angles and also they are equal.

∠ 3 and ∠ 4 are also vertical opposite angles and also they are equal.

For,

step 3. m∠ AEB = m∠ CED

Therefore, the reason for step 3 of this proof is Vertical Angles Theorem.

Simplify the answer

Andru [333]

Answer:

- 20 + 8i

Step-by-step explanation:

Noting that i² = - 1

Given

[(6i + 9) + (4i - 5)] × 2i ← evaluate the terms inside the square bracket

= ( 6i + 9 + 4i - 5 ) × 2i

= (10i + 4) × 2i ← multiply each term in the parenthesis by 2i

= 20i² + 8i

= 20(- 1) + 8i

= - 20 + 8i

A line passes through the point (5,-11) and has a slope of -2 Find an equation of this line.

Vsevolod [243]

Formula: y = mx + b

m being the slope

Slope given: -2, plug it in

Y = -2x + b

Now find y intercept (b)

Plug in the point (5,-11)

-11 = -2(5) + b

-11 = -10 + b, b = -1

Solution: y = -2x -1
