Although the options are not provided, the true statement is:
x = 5 is a true solution because log₂(16) = 4
In order to check if a solution is true, we may plug it back into the original equation. When we plug x into the equation we get:
log₂(5+11) = 4
log₂(16) = 4
4 = 4

As the left hand side of the equation is equal to the right hand side, the solution is true.

What is the 50th term of the sequence that begins -4, 2, 8, 14....?

vagabundo [1.1K]

Answer:

$a_{50}=290$

Step-by-step explanation:

Notice that we are in the presence of an arithmetic sequence (there is a common difference of 6 between a term and the next). So thisis an arithmetic sequence with first term $a_1=-4$ . and common difference "<em>d</em>" = 6.

Recall now the formula for the nth term ( $a_n$ ) of an arithmetic sequence:

$a_n=a_1+(n-1)\,d$

Then, using our values in the formula, we get:

$a_n=a_1+(n-1)\,d\\a_{50}=-4+(50-1)\,6\\a_{50}=-4+(49)\,6\\a_{50}=290$

Change 5x - y = 3 into slope-intercept form.<br> © by – 5x+3

agasfer [191]

The slope intercept form is $y=5x-3$

Explanation:

The equation is $5 x-y=3$

Now, we shall bring the equation $5 x-y=3$ in the slope intercept form.

The general form of the slope intercept is given by

$y=mx+c$

Hence, we need to rewrite the given equation in this form.

Thus, we have,

$5 x-y=3$

Subtracting both sides of the equation by 5x, we get,

$-y=-5x+3$

Multiplying both sides of the equation by (-), we get,

$y=5x-3$

Thus, the slope intercept form of the given equation is $y=5x-3$

Jen bought 5 CDs for $57.50, what was the unit price

frez [133]

Answer:

$11.50. Each CD cost $11.50.

Step-by-step explanation:

When trying to determine how much each CD cost, we need to know our total cost, $57.50, and how many CDs were bought, 5.

Since 5 CDs cost $57.50, we can divide our total cost by the number of CDs purchased to find the cost of each CD. 57.50 / 5 = 11.50
