A football is kicked from the ground and follows the graph of the function y = -x + 5t where y represents height and t represents seconds. At the same time, an arrow is launched from a height of 1 foot and follows the straight path y = 3. At seconds the football and the arrow are at the same height the second time. A. 1.7
B. 1.9
C. 2.1
D. 4.3​

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
