21x - 27 = 0 (add the 3x + 18x together since they’re like terms)

21x = 0+27 (move the -27 to the other side of the = and when you do the sign will become the opposite eg “-“ will become “+” and a multiply will become a divide)

x = 27 ÷ 21

x = 1.29 or 9/7

what you have to do it try and get x on its own on one side of the = so you shift all the other things to the other side i guess

Answer:

I. 6x2 + 25x + 24 = 0 6x2 + 16x + 9x + 24 = 0 2x (3x +8) + 3 (3x + 8) = 0 (2x + 3) (3x +8) ... < y=1; = x<y I. 10x2 + 33x + 27 = 0 => 10x2 + 15x + 18x + 27 = 0 => 5x (2x + 3) + 9 (2x + 3) = 0 => (5x +9) (2x +3) ... x = —9/5, –3/2 II. ... (b) 62 (d) is TX TX II.

What is the equation of the line that passes through the point (4,7) and has a slope of o?

Svetlanka [38]

Answer:

The equation of the line that passes through the point (4,7) and has a slope of 0 will be:

$y=7$

Step-by-step explanation:

As we know the equation of a line in a slope-intercept form of an equation is

$y = mx + b$

Here,

m is the slop

b is the y-intercept

so

substituting the point (4,7) and slope m=0

$y = mx + b$

$7=0(4)+b$

$7=0+b$

$b=7$

Therefore, the equation of the line that passes through the point (4,7) and has a slope of 0 will be:

$y = mx + b$

$y=0x+7$

$y=7$

The elves and reindeer are getting ready for a meeting with Santa.

Feliz [49]

Let $e$ and $r$ be the number of elves and reindeers, respectively.

We know that:

$r+e=14$ (so far 14 of them have arrived)

$4r+2e = 38$ (each reindeer has 4 legs and each elf has two)

If we multiply the first equation by 2 we have $2r+2e=28$ , and if we subtract this equation from the second we have $2r=10$ which implies $r=5$ .

So, there are 5 reindeers and 9 elves (remember that they have to sum up to 14).
