The reflection of any point across the x axis is the symmetric of this point, having x axis as axe of symmetry
Let :
A(1,3) its symmetric vs. x axis is A'(1,-3)
B(-1,5) its symmetric vs. x axis is B'(-1,-5)
C(-3,-3) its symmetric vs. x axis is C'(-3,3)
D(-4,-4) its symmetric vs. x axis is D'(-4,4)
Symmetry vs. the x axis keeps abscises the same & change just the sign of y value
Answer:
66.42
Step-by-step explanation:
66.42 is already rounded to the nearest hundredth.
2(6y − 3) = 20 + 6y
Use the distributive property, which states a(b - c) = ab - ac
We should get:
2*6y - 2*3 = 20 + 6y
Which can be simplified to:
12y - 6 = 20 + 6y
That means the mistake was in step 2. The student didn't multiply the numbers and instead added the numbers.
Your answer is: <span>Step 2: 12y-6=20+6y</span>
Answer:
UT=17 because both UT and RU are the same length, same with QU and US
Step-by-step explanation:
To determine the time it takes for boulder to reach its maximum height, derive the equation and equate to zero.
h = -16t² + 112t + 30
dh / dt = 0 = -32t + 112
The value of t from the equation above is 3.5 s. Substitute this value of t to the original question,
h = -16(3.5 s)² + 112(3.5 s) + 30 = 226 ft
Thus, the answer is letter D.
