6v+4w-4
Because you do -*-6v=positive 6v then -*-4w=positive 4w and then -*4=-4 and that takes care of the parenthesis
Basically you multiply the outside number or sign by all things inside the parenthesis
So in this problem you multiplied the negative sign by all the things inside the parenthesis
Answer:
Step-by-step explanation:
Answer:
<h2>A) y= -x + 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line<em>:</em>
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
==========================================
We have the points (-1, 2) and (4, -3).
Calculate the slope:
Put the value of the slope an the coordinates of the point 9-1, 2) to the equation of a line:
<em>subtract 1 from both sides</em>
Finally:
Answer:
(0, -3) and (3, 0)
Explanation:
1st equation: y = x² -2x - 3
2nd equation : y = x - 3
Using substitution method:
x² -2x - 3 = x - 3 <em>exchange sides</em>
x² - 2x - x - 3 + 3 = 0 <em>simplify</em>
x² - 3x = 0 <em> take common factor</em>
x(x - 3) = 0 <em>simplify</em>
x = 0, 3
Solve for y:
when x is 0, y = x - 3 = 0 - 3 = -3
when x is 3, y = x - 3 = 3 - 3 = 0
