Answer:
20%
Step-by-step explanation:
x times 5 = x2
Ex;
$50 +20%
20% of 50 = 10
Over 5 years, 10% x 5 years = $50
Answer:
3. Likely
Step-by-step explanation:
8 and 10 because 8 x 5 equals 40 and 10 x 4 equals 40. and 10 minus 8 is two
Answer:
the zero of a function is the value of x which makes the final value zero
First Equation:
So let 25 - 2x equal to 0
<em>25 - 2x = 0</em>
x = 12.5
Second Equation:
Let 2x² - 11x - 6 equal to zero
<em>2x² - 11x - 6 = 0 </em>
<em>2x² - 12x + x - 6 = 0 </em><em>(Splitting the middle term)</em>
<em>2x(x - 6) + 1(x - 6) = 0</em>
<em>(2x + 1) (x - 6) = 0</em>
So we can transpose either one of the brackets below the zero
(2x + 1) = 0 or (x-6) = 0
x = -1/2 or x = 6
5. complementary angles = 90°
90 - 40 = 50
50°
6. supplementary angles = 180°
180 - 40 = 140
140°
