Answer:
125i.
Step-by-step explanation:
5^3 is 125 i^2 is -1 so i^8 is positive and you have 1 i left.
Answer:
Step-by-step explanation: i think that u forgot the chart sorry i can not help
:(
I: y=(1/2)x+5
II: y=(-3/2)x-7
substitution:
fancy word for insert the definition of one variable in one equation into the other
-> isolate a variable, luckily y is isolated (even in both equations) already
-> substitute y of II into I (=copy right side of II and replace y in I with it):
(-3/2)x-7=(1/2)x+5
-3x-14=x+10
-3x-24=x
-24=4x
-6=x
-> insert x back into I (or II):
y=(1/2)x+5
=(1/2)*(-6)+5
=-3+5=2
elimination: subtract one equation from the other to eliminate a variable, again y is already isolated->no extra work required
I-II:
y-y=(1/2)x+5-[(-3/2)x-7]
0=(1/2)x+5+(3/2)x+7
0=(4/2)x+12
-12=2x
-6=x
-> insert x back into I (or II):
y=(1/2)x+5
=(1/2)*(-6)+5
=-3+5=2
Answer:
The system of inequalities is equal to
Step-by-step explanation:
Let
x-----> the number of hours that Malik works at a hardware store
y-----> the number of hours that Malik works as a lifeguard
we know that
-----> inequality A
-----> inequality B
Using a graphing tool
The solution is the shaded area
see the attached figure
He should have found the GCF of 7 and 9, not 3 and 9.
