20 points.....10u+4u-8u-3u now state the coefficient of the variable in the expression

1 answer:

5 0

10,4,-8,-3 these are the coefficients. Corrections are numbers that come before a variable so for example, the coefficient in 4x would be 4 so the number next to the variable

Company A: 120 + 0.50x

Company B: 60 + 0.60x

Company A = Company B (solve for x)

(Here, x = miles)

120 + 0.50x = 60 + 0.60x

120 - 60 = 0.60x - 0.50x

60 = 0.10x

600 = x

Solve ln 2 + ln x = 5. Round to the nearest thousandth, if possible.

azamat

Answer:

The value of x nearest to thousandths is, 74.207

Step-by-step explanation:

Solve : $\ln 2 + \ln x = 5$

$\ln$ represents the logarithmic function with base e.

Using logarithmic properties:

$\ln (mn) = \ln m + \ln n$

$\ln x = a$ , then $x = e^a$

$\ln 2 + \ln x = 5$

Apply the logarithmic properties; we have

$\ln 2x = 5$

then;

$2x = e^5$

$2x=148.41315910258$

Divide both sides by 2 we get;

$x = 74.2065796$

Therefore, the value of x nearest to thousandths is, 74.207

(3z+1)(4z+2) simplify

Lorico [155]

You can FOIL (First, Outside, Inside, Last)

(3z+1)(4z+2)

First

(3z+1)(4z+2)

3z * 4z

$12z^{2}$

Outside

(3z+1)(4z+2)

3z * 2

Inside

(3z+1)(4z+2)

4z * 1

Last

(3z+1)(4z+2)

2*1

Combine all the products of FOIL together

$12z^{2}$ + 6z + 4z + 2

Combine like terms

$12z^{2}$ + 10z + 2

Hope this helped!

When Scott got his dog Arfus, it weighed

Leokris [45]

It gained 2 lb. because if you subtract 8-6 you would get 2. So Arfus gained 2 lb.
