Suppose f(x)=4x-2 and g(x)=-2x+1. Find the value of f(5)/g(-3)

IrinaVladis [17]

Answer:

17/7 (2 3/7 or 2. 428571...)

Step-by-step explanation:

f(x) = 4x-2

Find f(5)

f(5) = 4(5)-3
f(5) = 20-3
f(5) = 17

g(x) = -2x+1

Find g(-3)

g(-3) = -2(-3)+1
g(-3) = 6+1
g(-3) = 7

Find f(5)/g(-3)

f(5)/g(-3)
17/7 (2 3/7 or 2. 428571...)

3. Solve each of the following constant coefficient ordinary differential equations: (10 pts] a) y"+ 3y'- 28y = 0

eduard

Answer:

$y(t) = C_1e^{4t} + C_2e^{-7t}$

Step-by-step explanation:

We are given the following information in the question:

$y''+3y'-28y = 0$

This can be written as:

$(D^2 + 3D - 28)y = 0$

The auxiliary equation obtained is:

$m^2+ 3m - 28 = 0\\ m^2 + 7m - 4m - 28 = 0\\m(m+7)-4(m+7)=0\\(m-4)(m+7)\\m = 4, m = -7$

Thus, the general solution of the equation is:

$y(t) = C_1e^{4t} + C_2e^{-7t}\\\text{where } C_1, C_2 \text{ are constants}$

80% of x is 48 what is x and what is an equation that I can use to solve?<br><br> Please help!!

butalik [34]

X would be 60, I don’t know an equation, but you can divide both sides by 4 and get 20% of c is 12, and then you can multiply both sides by 5 to get that 100% of x is 60, hope this helps!
