Answer:
choice G. (-5, 2)
Step-by-step explanation:
(x + 5)^2 + (y - 2)^2 = 9
(x + 5)^2 + (y - 2)^2 = 3^2
center( -5, 2)
Answer:
the answer is 93
Step-by-step explanation:
mean of x,y,z
x+y+z
3 terms
(x+y+z)/3=mean
so
represent next test score as x
89+94+82+84+98+x
count how many terms ther are (6 terms)
mean is 90
(89+94+82+84+98+x)/6=90
add the like terms
(447+x)/6=90
multiply both sides by 6 to clear fraction
447+x=540
subtract 447 from both sides
x=93
So we notice that they increase by 1
each time
first slot we have all of them so
4 choices=1st slot
3 choices=2nd slot (1 was taken for 1st slot)
2 choices
1 choice
multiply
4 times 3 times 2 times 1=24
answe ris 24 ways
Susana=s
maria=m
m= 3s/5
s+m=56
s+(3s/5)=56
(5s+3s)/5=56
8s=56*5
8s=280
s=280/8
s=35
35 --->5/5
x ---> 3/5
x= (3/5)*35 / (5/5)
x=21
edad de maria= 21 años
