4 is the answer I guess guyyyysss. Than
Answer:
She needs 112 ounces of Solution A and 48 ounces of Solution B.
Step-by-step explanation:
If a is the ounces of Solution A, and b is the ounces of Solution B, then:
a + b = 160
0.45a + 0.95b = 0.60(160)
Solve the system of equations. Using substitution:
0.45a + 0.95(160 − a) = 0.60(160)
0.45a + 152 − 0.95a = 96
56 = 0.5a
a = 112
b = 48
She needs 112 ounces of Solution A and 48 ounces of Solution B.
Answer:
Y'=3xy-3x-12
Y'=F(-2,-1)=0
Step-by-step explanation:
The function of the equation at the point (-2,-1)
is where the equation make the function go to zero:
Y'=3xy-3x-12
Y'=F(-2,-1)=[3(-2)(-1)]-[3(-1)]-12
F(-2,-1)=[6]-[-6]-12
F(-2,-1)=6+6-12
F(-2,-1)=12-12
F(-2,-1)=0
Solving for y
3xy-3x-12=0
y=4/x+x
Making y=0
So the values make the function go to zero
