Answer:

The answer is 5a-35.

Step-by-step explanation:

So, since you told me to explain, if a number is right next to a parentheses without any signs you multiply it.

But instead of doing 5 times 7a, you multiply both of them separately.

5 times a is pretty much just 5a. 5 times -7 is -35.

As a result, you will be left with 5a-35.

If you have anymore questions, let me know.

Answer:(-4,3)

Step-by-step explanation:

Here, Every equation has same slope (-4) and same y-intercept (3), so we don't need to calculate those.

Now, as coordinates are in left-portion, and also touches the line, it would be: y ≥ -4x + 3

A vine called the mile a-minute weed is known for growing at a very fast rate. It can grow up to 0.25 inches

jek_recluse [69]

Answer:

$\displaystyle =\frac{0.5\text{ ft}}{\text{day}}$

The weed grows at a rate of 0.5 feet per day.

Step-by-step explanation:

The weed grows at a rate of 0.25 inches per hour.

And we want to convert this rate into feet per day.

We have that:

$\displaystyle \frac{0.25\text{ in}}{\text{hr}}$

We knowt that there are 12 inches in one foot.

And since we want to cancel the inches, we can write our conversion factor as ft / 12 in.

We also know that there are 24 hours in one day.

And since we want to cancel the hours, we can write our conversion factor as 24 hr / day.

Hence:

$\displaystyle \frac{0.25\text{ in}}{\text{hr}}\cdot\frac{\text{ft}}{12\text{ in}}\cdot \frac{24\text{ hr}}{\text{day}}$

Multiply and cancel common terms. So:

$\displaystyle =\frac{0.5\text{ ft}}{\text{day}}$

The weed grows at a rate of 0.5 feet per day.

Write the first five terms of the sequence defined by the explicit formula.

AlexFokin [52]

Answer:

(a) 112, 28, 7, (7/4), (7/16)

Step-by-step explanation:

The sequence is given by the explicit formula

$a_{n} = 112 (\frac{1}{4} )^{n-1}$

The terms of the sequence are :

$a_{1} = 112 (\frac{1}{4} )^{1-1} = 112 (\frac{1}{4} )^{0} =112$

$a_{2} = 112 (\frac{1}{4} )^{2-1} = 112(\frac{1}{4} ) =28$

$a_{3} = 112 (\frac{1}{4} )^{3-1} = 112(\frac{1}{4} )^{2} = 7$

$a_{4} = 112 (\frac{1}{4} )^{4-1}=112(\frac{1}{4} )^{3} = \frac{7}{4}$

$a_{5} = 112 (\frac{1}{4} )^{5-1}=112 (\frac{1}{4} )^{4} = \frac{7}{16}$
