Answer:
Step-by-step explanation:
f(x) = x^3 - 3x^2 - 28x + 60
x(x^2-3x-28)+60
Factor the inside of the parenthesis
Multiples of 28: (1X28),(2X14),(4X7). 7-4=3, 7 & 4 is the correct multiple.
x(x-7)(x+3)+60
Roots: 0,7,-3,6
Also you can plug your function into Desmos and see where it crosses the x-axis.
Answer:
the above is a function
Step-by-step explanation:
function is a mapping from a set A to B, which associative every element of A with unique image in B.
Here, f(-3)=6, f(-5)=6
f(3)= -2, f(-5)=1
all elements have image.
so this is a function.
Answer:
Mike is right. 152 is larger than 33 + 53/
Step-by-step explanation:
First we need to add 53 + 33 to see if it will equal up ro 152. So 53 + 33 = 86.
86 is less than 152, so Mike is correct and Karen is wrong, as usual.
First step is square root both sides leaving with
x-6=+/-3
closest one is A
answer is A
Answer:
answers below and explained
Step-by-step explanation:
a) 2 (2 times 3) + 5 (3)
2 (6) + 5 (3)
12 + 15
= 27
b) a = 3 + 3
a = 6
c) 3(2a+1) - 6a + 7 = 10
6a + 3 - 6a + 7 = 10
3 + 7 = 10
