1. GCF is a factor that is shared by all terms within a polynomial for example, if we have a polynomial of the form A*B + A*C, the GCF is A since both terms have A as a factor 2. after we factor out the GCF, it is placed outside the parentheses, in front of the rest of the polynomial. using our previous example, A*B+A*C = A(B+C) 3. we can verify that our factoring is correct by distributing the GCF to the polynomial within the parentheses
Two negatives added or multiplied make a positive.
Answer:
x= 1.75 y= 6.75
Step-by-step explanation:
substitution method
For palarell lines, slope are equal.
slope of first line = (y2 - y1)/(x2 - x1) = (-7 - 9)/(-12 - 8) = -16/-20 = 4/5
equation of a line passing through a point is given by: y - y1 = m(x - x1); where (x1, y1) = (-5, -15) and m = 4/5.
Therefore equation of the line is y - (-15) = 4/5(x - (-5))
y + 15 = 4/5(x + 5)
Answer:
+25;+18;-10
Step-by-step explanation:
Ok so let's break down the scenario step by step:
- His uncle gave him $25 so that means it's positive so <em>+</em><em>25</em><em> </em>
- Now he earned $18 so that means it is also positive so <em>+</em><em>18</em>
- And now he spent $10 which means it is negative so <em>-</em><em> </em><em>10</em>
(And of you want to find out the amount left with him,
(25+18)-10
=43-10
=$33)
Hope this helps :)
