Answer:
(21, 5)
Step-by-step explanation:
y = -x
y = -(-7)
y = 7
The point is reflected, so it is equidistant on both sides of the reflection line. It takes 14 units to get to the reflection line, -7 + 14 = 7 (the reflection line).
So, another 14 on the other side would be 14 + 7 = 21

There is only one sign changed in the whole equation so possibly the answer must be one. correct me if I'm wrong
Answer:
The length is 600 ft
Step-by-step explanation:
We can solve this by applying the Pythagorean theorem
a^2 + b^2 = c^2
The hypotenuse (diagonal path) is 750
750 represents c, 750^2 is 562500
We also know the width (one side of the triangle)
450 can represent a, 450^2 is 202500
202500 + b^2= 562500
We can subtract 202500 on both sides to isolate the b^2
b^2= 360000
Square root both sides of the equation
B= 600
The length is 600 ft
Answer:
the area is 92.4
Step-by-step explanation:
you just multiply the base and height to get the area
Answer:
a = sqrt(7)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
a^2 +3^2 = 4^2
a^2 +9 = 16
a^2 = 16-9
a^2 = 7
Taking the square root
a = sqrt(7)
