Answer:36cm
Step-by-step explanation:
Answer: -4
Work: So, to get -4, we need to simplify the equation. If you see any equation with +(- that's subtraction. So, with the rule, this equation is basically 8-12, and that's -4.
Answer:
-4x +3
Step-by-step explanation:
Given the functions f(x) = -2x + 3 and g(x) = 2x We are to find the composite function (f*g(x))
(f*g(x)) = f(g(x))
f(g(x)) = f(2x)
f(2x) = -2(2x) + 3
f(2x) = -4x +3
Hence f(g(x)) = -4x +3
Answer:
Yes, this equation has a solution. According to Intermediate Value Theorem at least one solution for [0,2]
Step-by-step explanation:
Hi there!
1) Remember a definition.
Intermediate Value Theorem:
If 
is continuous on a given closed interval [a,b], and f(a)≠f(b) and f(a)<k<f(b) then there has to be at least one number 'c' between 'a' and 'b', such that f(c)=k

(Check the first graph as an example)
2) The Intermediate Value Theorem can be applied to determine whether there is a solution on a given interval.
Let's choose the interval ![[0,2]](https://tex.z-dn.net/?f=%5B0%2C2%5D)
Proceed to the other point: 2
3) Check the 2nd Graph for a the Visual answer, of it. And the 3rd graph for all solutions of this equation.
Answer:
c
Step-by-step explanation:
C. BD= 20
Use similar triangles to write a proportion and then cross multiply to solve.
AE: AC = AD:AB
(ONCE YOU KNOW AB YOU CAN SUBTRACT AD FROM AB TO GET BD =20)
So, 15:40 = 12: AB=32. now 32-12 = 20 so BD = 20
