Answer:

c=10(g+5)

Step-by-step explanation:

Given that,

The cost of customer smartphone bill is given by the equation as follows :

c=10g+50

Where

g is the number of gigabits of data the customer per month

We need to factor this cost polynomial

The common between 10 and 50 is 10

Taking 10 common. So,

c=10(g+5)

Hence, the required factor is equal to c=10(g+5).

Which is the axis of symmetry of a parabola with equation x^2=-4y?

riadik2000 [5.3K]

Answer:

x = 0

Step-by-step explanation:

Given

x² = - 4y ( divide both sides by - 4 )

y = - $\frac{1}{4}$ x²

Which is a parabola opening vertically down with it's vertex at (0, 0) and symmetrical about the y- axis

Hence equation of axis of symmetry is x = 0

5-year Treasury bonds yield 5%. The inflation premium (IP) is 1.9%, and the maturity risk premium (MRP) on 5-year bonds is 0.4%.

Eddi Din [679]

Answer:

real risk-free rate = 2.7 %

Step-by-step explanation:

Given data

Treasury bonds yield r = 5%

time = 5 year

(IP) = 1.9%

MRP = 0.4%

to find out

real risk-free rate r*

solution

we will find real risk-free rate r* by the given formula that is

Treasury bonds yield = real risk-free rate + IP + MRP + default risk premium + liquidity premium

so here default risk premium and liquidity premium both are zero

put all the other value we get real risk-free rate

real risk-free rate = 5% - 1.9 % - 0.4%

real risk-free rate = 2.7 %

Answer:

The solution is: (1,-3)

Step-by-step explanation:

Given equations are:

x-y=4 Eqn 1

4x+y = 1 Eqn 2

Substitution involves finding value of a variable from one equation and putting in other equation

From equation 1

x = y + 4

Putting in equation 2

$4(y+4) + y = 1\\4y+16+y = 1\\5y = 1-16\\5y = -15\\\frac{5y}{5} = \frac{-15}{5}\\y = -3$

Putting y = -3 in equation 1

$x- (-3) = 4\\x + 3 = 4\\x = 4-3\\x = 1$

Hence,

The solution is: (1,-3)
