Step-by-step explanation:
pythogoras theorem = Q²=P²+R²
P=P
Q= 57.6
R=33.8 =
(57.8)²=(P)²+(33.8)²
=3,340.84=(P)²+1142.44
=3340.84-1142.44=P²
=2,198.4=P²
She work 11 hours for $253. We can find hourly rate by divide 253 by 11 to get 23 dollars per hour
So it’s $23/hour * 17 hours = $391
Step-by-step explanation:
a.
if x=-1 then,
y=2*(-1)-1
y=-2-1
y=-3
if y=-1 then,
-1=2x-1
-2x=-1+1
-2x=0
x=0
if x=1 then,
y=2*1-1
y=2-1
y=1
if y=3 then,
3=2x-1
-2x=-1-3
-2x=-4
-2/-2x=-4/-2
x=2
b.
if x=0 then,
0+y=-2
y=-2
if x=1 then,
y+1=-2
y=-1-1
y=-3
if x=2 then,
y+2=-2
y=-2-2
y=-4
if x=3 then,
y+3=-2
y=-2-3
y=-5
