How many solutions does the equation −4a + 4a + 3 = 8 have? Zero One Two Infinite solutions

1 answer:

7 0

Hi there!

Let's solve this equation step by step!
$- 4a + 4a + 3 = 8$

First we collect the terms (the variables 'a', which add up to 0).
$3 = 8$

Obviously, this expression is FALSE, since 3 doesn't equal 8. Therefore the equation does not have any solutions. Whatever value of 'a' you plug into the equation, the right side of the equation will always be 5 bigger. Hence, the answer is zero.

Find the area of the triangle defined by the coordinates (-3, -4), (-7, 0), and (-3, 4).

mr Goodwill [35]

The area of a Triangle is 1/2BH (B=Base length, H=Height)
When looking at the points, we can figure out the following:

The distance between the two points at the base is 8 (to get from -4 to 4 you must add 8) and the height is 4 (to get from -4 to 0 as well as 0 to 4, the distance is 4).

Now we plug in our values:
Area= 1/2(8)(4)
=1/2(32)
=16 Units squared

Therefore, your answer is 16 units squared.

I hope this Helps!

Given:

Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.

The money that he has saved so far is 30% of the cost of the bike.

We need to determine the total cost of the bike.

Total cost of the bike:

Let x denote the total cost of the bike.

The total cost of the bike is given by

$30\% \ of \ x=150$
