Y=2x+5
sub 2x+5 for y in other equaiton
10x+3(2x+5)=19
distribute
10x+6x+15=19
minus 15 from both sides
16x=4
divide both sides by 16
x=1/4
sub back
y=2x+5
y=2(1/4)+5
y=1/2+5
y=5.5=11/2
solution is (1/4,11/2) or in decimal, (0.25,5.5)

<u><em>Answer:</em></u>x = −4 and x = 1
<span>
<u><em>Explanation:</em></u><u>The two formula's given are:</u>
f (x) = -x+0.5 and g (x) = x²+3x-4
By graphing the two in a graphing tool or graph paper we can find the solutions by looking at <u>the points of intersection</u> and taking the x values of those two points of intersection.
<u>Looking at the graph below:</u>
x=-4 and x=1 are the solutions to the problem.</span></span>

Answer:
8 hours
Step-by-step explanation:
rental fee = 12 + 4/hr
spent = 44
44 = 12+4(hr)
32 = 4(hr)
32/4 = hr
hr = 8
