Answer:
Step-by-step explanation:
an exponential equation has the form y=ar^x where y=final amount, a=initial amount, r=rate, and x=time, in this case
y=200(1.18)^x
4x+8y=40
0.8*8=6.4
4x+6.4=40
40-6.4=33.6
4x=33.6
33.6\4=8.4
X=8.4
9/2 that the answer ok ok
<span>The Gonzalez family drove 342 miles in 6 hours. 342 ÷ 6 = 57 mph</span>
<span /><span>The Wilson family drove 472 miles in 8 hours. 472 ÷ 8 = 59 mph</span>
<span>So your answer is D. Wilson; 59 mi/h</span>
<span>Hope this helps. :)
