B)  If we subtract females who prefer dogs from the total that prefer dogs we will know how many males prefer dogs.

290-180=110

So 110 males prefer dogs.

c)  180 females prefer dogs and 12 prefer fish, so 180+12=192 females do not prefer cats.

A father is 3 times as old as his son and his daughter is 3 years younger than the son. Fi the sum of there ages 3 years ago was
inn [45]

Answer:the present age of the father is 45 years

Step-by-step explanation:

Let x represent the present age of the father.

Let y represent the present age of the son.

Let z represent the age of the daughter.

A father is 3 times as old as his son. This means that

x = 3y

his daughter is 3 years younger than the son. It means that

z = y - 3

The sum of their ages 3 years ago was 63. This means that

x - 3 + y - 3 + z - 3 = 63

x + y + z - 9 = 63 - - - - - - - - - - 1

Substituting x = 3y and z = y - 3 into equation 1, it becomes

3y + y + y - 3 - 9 = 63

5y - 12 = 63

5y = 63 + 12 = 75

y = 75/5 = 15

x = 3y = 3 × 15

x = 45

z = y - 3 = 15 - 3

z = 12

Find all zeros of x^4+x
Yuri [45]

Answer:

-1 and 0

Step-by-step explanation:

X ^4+x = 0;

x*(x^3+1)=0;

x*[(x^3-x)+(x+1)]=0;

x*[x(x-1)(x+1)+(x+1)]=0;

x*(x+1)(x^2-x+1)=0;

Since x^2-x+1=0 has no intersection with the X-axis, there is no x value such that y=0

x=0 or -1
