Answer:
y = -2x -7
Step-by-step explanation:
y + 5 = -2 (x +1)
y + 5 = -2x -2 . move 5 to the other side by subtracting from both sides.
y = -2x -7
It would be like this , this is how you would graph it
Answer:
-50
Explanation:
At sea level would be 0 so anything above would be a positive number and anything below a negative number.
Answer:
45
Step-by-step explanation:
<u>First we want to understand the Base Angles Theorem</u>
The Base Angles Theorem tells us that the base angles or the two bottom angles of an isosceles triangle are congruent.
Using this theorem, we can say that angle A and angle G are congruent meaning m∠A = m∠G. We can then write both of them as x.
We can create the equation ∠N + ∠A + ∠G = 180 degrees.
Knowing ∠N and knowing ∠A + ∠G = 2x, we can rewrite the equation into
<em>90 + 2x = 180</em>
We can then solve for x,
<em>90 + 2x - 90 = 180 - 90</em>
<em>2x = 90</em>
<em>2x / 2 = 90 / 2</em>
<em>x = 45 </em>degrees
The point P(1, 3) is one unit up of the line y = 2, a refrection image of P(1, 3) across the line y = 2 will be one unit down of the line y = 2.
Therefore, the coordinate of the refrection image is (1, 1).
