I would go with A... But im not quite sure :) Good luck
Answer:
x=4, y=9/7
Step-by-step explanation:
We will use the property that the opposite sides of a rectangle are equal
3(3y-1)=2(y+3)
9y-3=2y+6
7y=9
y=9/7
2x=4(x-2)
2x=4x-8
2x=8
x=4
Answer:
(-7)(-1.2)=8.4
(7)(-1.2)=-8.4
(2.5)(-2)=-5
(-2 1/2)(2)=5
Step-by-step explanation:
First,a negative multiplied by another negative will have a product that is positive.
Also, -2 1/2 is the same as -2.5
Answer:
110.9 feet
Step-by-step explanation:
The function that models the flight of the ball is
where f(x) is the vertical distance in feet and x is the horizontal distance the ball travels
If the ball hits the ground, then f(x)=0
The solution is given by the quadratic formula:
We substitute a=-0.02, b=2.2, and c=2 to get:
This implies that:
Since we are dealing with time,
To one decimal place, we have 110.9 feet
Answer:
180°
Step-by-step explanation:
Well we know that AB is 90° and considering CB is the exact same I guess it's 90° too so 90+90=180°
