Answer:

A the system has no solution

Step-by-step explanation:

Simplifying 2x + -5y = -8

Solving 2x + -5y = -8

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '5y' to each side of the equation. 2x + -5y + 5y = -8 + 5y

Combine like terms: -5y + 5y = 0 2x + 0 = -8 + 5y 2x = -8 + 5y

Divide each side by '2'. x = -4 + 2.5y Simplifying x = -4 + 2.5y

Solution for 2x-5=12 equation:

2x - 5 = 12

2x = 12 + 5

2x = 17 (divide both sides by 2 to get x)

2x/2 = 17/2

x = 8.5

Express the given logarithm in terms of common logarithms. Then approximate its value to four decimal places.

zhannawk [14.2K]

Answer:

3.4594

Step-by-step explanation:

To change the base of a logarithm

• $log_{b}$ x = $\frac{log_{c}x }{log_{c}b }$

where c represents the new base

Changing the base from 2 to 10

$log_{2}$ 11 = $\frac{log_{10}11 }{log_{10}2 }$ ≈ 3.4594

Michael drove his car for 150 minutes at a constant speed of 75 miles per hour and then for another 2 hours at a constant speed

swat32

Answer:

he traveled a total of 349.5 miles.

Step-by-step explanation:

*First we convert the 150 minutes to hours, that is :

$h=\frac{1.150}{60} \\h=2.5$

Now we determine the distance Michael traversed during those 2.5 hours:

$d_{1} =2.5.75 \\d_{1} =187.5\\$

He transversed 187.5 miles.

We also determine the distance he tranversed the two remaining hours:

$d_{2} =2.81 \\d_{2} =162$

He also traveled 162 miles

Finally we add both traversed distances:

$d_{t}=187.5+162 \\d_{t} =349.5\\$

So , he traveled a total of 349.5 miles.
