Answer:
y=3x.........1
y=x^2-10.......2
substituting value of eq 1 to 2
3x=x^2-10
x^2-10-3x=0
x^2-3x-10=0
x^2-5x+2x-10=0
X(x-5)+2(x-5)=0
(x-5)(X+2)=0
then
X=5 or X=-2
again
y=??
when X=5
y=3×5=15
when X=-2
y=-6
Answer:
64 cars
Step-by-step explanation:
total number of cars that the parking lot can hold = 8/3 × 24 = 64 cars
Domain : (-5, -4, -2, 0, 1)

Answer:
Trapezoid
21 is the perimeter.
24 is the area.
Step-by-step explanation:
Let's do the perimeter first, 8 + 4 = 12.
Now we have to get the side lengths. We can do this by using the Pythagoras Theorem by making an imaginary line to form a right triangle. The lengths are 2 and 4. So, 4 + 16 = 20. Square root of 20 + square root of 20 = ~9
12 + 9 = 21
21 is the perimeter.
Now, let's solve the area. The a is 4, b is 8. So 4 + 8 = 12/2 = 6. The height is 4 so 6 * 4 = 24.
24 is the area.

Answer:2/7
Step-by-step explanation: A reciprocal is the "mirror image" of a fraction so the reciprocal is the fraction upside down.
