Answer:
a) 5
Step-by-step explanation:
Put them into slope intercept form AKA y=mx+b: -5=m1+b <em>and</em> 5=m3+b
Subtract the equations to get -10=-2m
Divide both sides by two to get: 5=m
Hope this helps! (^-^)
Subtract the 7 from both sides,
you are left with
11=y
Y² + 16 = 212
<span>y</span>² <span>= 196 </span>
<span>y = -14 and 14</span>
The answer is 15.525. All you have to do is divide 279.45 by 18 which gives you 15.525.
