Answer:

  (-3, 3)

Step-by-step explanation:

Substitute for y:

  x+6 = -2x -3

  3x = -9 . . . . . . . add 2x -6 to both sides

  x = -3 . . . . . . . . divide by 3

  y = (-3) +6 = 3 . . substitute for x in the first equation

The solution is ...

  (x, y) = (-3, 3)

a line passes through (9, –9) and (10, –5).write an equation for the line in point-slope form. rewrite the equation in standard
Cerrena [4.2K]
The equation of the line in point-slope form is given by:
 y-yo = m (x-xo)&#10;
 Where,
 (xo, yo): point that belongs to the line
 m: slope of the line
 The slope is given by:
 m = \frac{y2-y1}{x2-x1}
 Substituting values:
 m = \frac{-5-(-9)}{10-9}
 Rewriting:
 m = \frac{-5+9}{10-9}
 m = \frac{4}{1}
 m=4
 Now we choose an ordered pair:
 (xo, yo) = (10, -5)&#10;
 Substituting values we have:
 y-(-5)=4(x-10)
 y+5=4(x-10)
 We now rewrite the equation in its standard form:
 y = mx + b&#10;
 Where,
 b: cut with the y axis.
 We have then:
 y = 4x - 40 - 5&#10;&#10;y = 4x - 45
 Answer:
 point-slope form:
 y+5=4(x-10)
 or
 y+9=4(x-9)
 standard form
 y = 4x- 45

What is x² + 7x - 30​
Aleonysh [2.5K]

Are you looking for the value of x?

We can complete the square/factor:

x^2+7x-30=0

(x+10)(x-3)=0

By the zero product property rule, we have two equations, x+10=0 and x-3=0.

So the zeroes of x are -10 and 3

Hope this helped. Comment below if this didn't make sense.
