Answer:
-22
Step-by-step explanation:
-3•f(-8)+7•g(2)=
The value of f(x) at x=-8 is
f(-8) = -2
The value of g(x) at x=2 is
g(2) = -4
Substituting these values into the equations
-3 * -2 +7*-4
6 -28
-22
<u>ANSWER: </u>
If x = 
and x = -3 are the roots of the equation, then values of a and b are 3, -6
<u>SOLUTION:
</u>
Given, quadratic equation is 
and its roots are -3 ,
We know that, for any quadratic equation of form 
with roots 
then,
Sum of roots 
= 
Product of roots ( 
= 
Now, for given quadratic equation 
= -3 and 
=
hence Sum of roots = 
on solving we get "a" = 3
Now product of roots = 
b = -6
hence, the values of a and b are 3, -6.
Answer:
Step-by-step explanation:
In probability, "OR" means "+" and "AND" means "*".
The total amount of people is:
32 + 54 + 78 + 112 + 96 = 372
Number of diabetic patients are 54
Number of eye patients are 112
Since we want "OR", we will add the two probabilities:
P(diabetic or eye problem) = 54/372 + 112/372 = 83/186
Answer:
43.75

It you want to find the speed of the cat, all you have to do is divide 35 by 0.8.
Answer:
5 video games.
Step-by-step explanation:
In order to find the total number of video games that Tracy can buy with the money, she has we first need to find how much money she has left after buying the clothes. To do this we subtract the amount she spent on clothes by the initial total that Christina had.
120 - 68 = 52
Now that we know Christina has a remaining $52, we can divide this amount by the value of each individual game ($10) in order to calculate how many she can actually afford.
52 / 10 = 5.2
Finally, we can see that she can afford to only buy 5 video games.
