2 answers:

4 0

First you have to find slope:
m = -2 - 4/2 - -1
m = -6/3
m = -2

Then plug any points into equation
y = mx + b to get b
-2 = 2(-2) + b
-2 = -4 +b
B = 2

So you're equation is:
y = -2x + 2

Una clase de 32 se dividen para ir al cine y el otro grupo a la piscina. Si la entrada de la piscina cuesta 2,5 euros y la del c

AveGali [126]

Answer:

14 children went to the movies and 18 went to the pool.

14 niños en el grupo del cine y 18 en el grupo de la piscina.

Step-by-step explanation:

We can solve this question using a system of equations.

I am going to say that:

x is the number of children that went to the movies.

y is the number of children that went to the pool.

Class of 32:

This means that $x + y = 32$

To go to the pool, it costs 2.5 euros. To go the movies, it costs 3.5 euros. 94 euros were spent.

This means that $3.5x + 2.5y = 94$

From the first equation:

$y = 32 - x$

Replacing in the second

$3.5x + 2.5y = 94$

$3.5x + 2.5(32 - x) = 94$

$3.5x + 80 - 2.5x = 94$

$x = 14$

$y = 32 - x = 32 - 14 = 18$

14 children went to the movies and 18 went to the pool.

14 niños en el grupo del cine y 18 en el grupo de la piscina.

A tip of $6.30 is what percent of a $35 dollar bill

Kobotan [32]

In other words, it's asking what fraction is $6.30 out of $35. So let's make a fraction.
$\frac{6.30}{35}$

Remember that the fraction sign is a division sign. So 6.30/35 = 6.30<span>÷35, which equals 0.18.

Converting the decimal 0.18 to a percent, multiply by 100 (move decimal two places to the right) and tag the % sign at the end.
0.18 = 18%</span>

Arrange the given polynomial in descending order.<br> 9x? + 9x +3+2x

WARRIOR [948]

20x+3
This shouldddd be the answer sorry if I’m wrong, but if you group all the x variables together they add up to twenty, then you just add “+3” being that it has no x and therefore must be put in some form of separate group!
