Answer:
Original figure: (-6,-5)
final figure: (-6, 5)
Step-by-step explanation:
the point would fall at (-6, 5) because it is reflecting across the x-axis (the horizontal one) and since it is the original point is 5 away from the x-axis, the final point would be at 5 as well. the y-coordinate doesn't change because it is only reflecting over the x-axis. the shape would essentially be flipped if you reflected it over the x-axis, so the point would be on the bottom of the figure instead of the top. Hope this helps I tried my best to explain!
Answer:
Step-by-step explanation:
v(5v-7)=0
We multiply parentheses
5v^2-7v=0
a = 5; b = -7; c = 0;
Δ = b2-4ac
Δ = -72-4·5·0
Δ = 49
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
v1 = −b−√Δ/2a
v2 = -b+√Δ/2a
√Δ = √49 = 7
v1 = -(−7)−7/2*5 = 0/10 = 0
v2 = -(−7)+7/2*5 = 14/10 = 1+2/5
In one hour he would cycle 18Km, therefore in a 1/4 hour the cyclist would ride a 1/4 of 18 = 4.5Km.
So what you can do is take 49 and divide it by 2 cause times is multiplication so if you take 49 and divide that by 2 you would get 24.5. Now if you plug so like 24.5 · 2 would would get 49.
~Good Luck~
Answer:
t = -18, 18
Step-by-step explanation:
Take the square root of both sides of the equation.
... t = ±√324 = ±18
