Answer:
4 km
Step-by-step explanation:
1000m:3m = 4000m:12m
<span>For this case what you should do is write the following function:</span>
<span> y = (a / b) * 100</span>
<span> Where,</span>
<span> A: amount of successful free throws</span>
<span> B: total amount of free throws</span>
<span> Substituting values we have:</span>
<span><span> y = (21/30) * 100</span></span>
<span><span> The result is:</span></span>
<span><span> Y = 70% (as we expected)</span></span>
<span><span> Answer:</span></span>
<span><span> a rational function that can model the player's free throw percentage is:</span></span>
<span><span> <span>y = (21/30) * 100</span></span>
</span>
Y = 5 - 3x....so sub in 5 - 3x for y in the other equation
5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1
now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2
check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)
so ur solution is (1,2)
