Answer:
Option 4. x = 0
Step-by-step explanation:
we know that
The rule of the reflection of a point across the y-axis is equal to
(x,y) -----> (-x,y)
The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the y-value the same
The coordinates of triangle PQR are
P(1, 4), Q(3, 6), and R(5, 2)
Applying the rule of the reflection across the y-axis we have
P(1, 4) -----> P'(-1, 4)
Q(3, 6) ----> Q'(-3, 6)
R(5, 2)----> R'(-5, 2)
The reflection line is the y-axis
Remember that the equation of the y-axis is x=0
therefore
The equation of the reflection line is x=0

<h2>Round 2 scores are higher than round 1 scores.</h2>
The first one adds up to 34 while the second adds up to 36. This puts C and D to false.
Answer:
(-1,9)
Step-by-step explanation:
y = -3x + 6
y = 9
-3x + 6 = 9
-3x = 3
x = -1
y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,
-3(-1) + 6 = 9
(-1,9)
So information you gathered are:
- Region is square with side length 175 km
- There was about 214 plants per square kilometer (km²)
So first we need to find area of region. That would be 175 km × 175 km = 30625 km²
So now we know that for each single square with length 1km, there are 214 plants. So then we would need to multiple density by total area to get approximation for the total number of cactus plant.
( 214 plants / 1 km² )( 30625 km² )
Which is roughly same as ( 200 )( 30000 ) = ( 3 × 10⁴ )( 2 × 10² )
Hope this helps.
