Answer:
450 feet at ground level
Step-by-step explanation:
The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.
This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.
This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.
Answer:
Step-by-step explanation:
x + 15 = 24
subtract 15 from both sides
x = 24 - 15 = 9
Answer:
y = 3/2x -14
Step-by-step explanation:
do the inverse of -2/3 what is 3/2
and now sole the equation of y+8 = 3/2(x-4)
distribute 3/2 ---> y+8 = 3/2x - 8
subtract 8 from both sided getting you y=3/2x-14
