Candice drove 22 miles. 66 divided by 3 is 22. Which means Marcos drove 44 miles.

Which equation can be rewritten as x + 4=x2 assume x>0

antoniya [11.8K]

I'm guessing that x2 is an x to the power of 2, so u can rewrite that as:

x^2 - x - 4

from there you can use completing the square, quadratic function, or factoring.

If the x2 is supposed to be 2x then it would just be as follows:

x - 4

Answer:

y-6 = -7x + 21

Step-by-step explanation:

Find the slope

(-8 - 6)/(5-3)

-14/2 = -7

Now find the formula

y-6=-7(x - 3)

y-6 = -7x + 21

Another way to write it is

y= -7x + 27

Answer:

$\displaystyle y = \frac{1}{4}x - 1$

Step-by-step explanation:

1 = ¼[8] + b

2

$\displaystyle -1 = b \\ \\ y = \frac{1}{4}x - 1$

* Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so −4 becomes ¼.
