To turn a fraction into a decimal, divide the numerator by the denominator. For example, to turn 5/10 into a decimal, divide 5 with 10 and you will get 0.5. So, the decimal for 5/10 is 0.5.
Hope it helps:)
Answer:
Step-by-step explanation:
<em>(a).</em> 2( 2 )³ + a ( 2 )² - b ( 2 ) + 12 + ( 18 ) = 0
16 + 4a - 2b + 30 = 0
4a - 2b = - 46
<em>2a - b = - 23</em> ....... <em>( 1 )</em>
2 ( - 4 )³ + a ( - 4 )² - b ( - 4 ) + 12 = 0
- 128 + 16a + 4b + 12 = 0
16a + 4b = 116
<em>4a + b = 29</em> ........ <em>( 2 )</em>
<em>( 1 )</em> + <em>( 2 )</em>
6a = 6 , <em>a = 1</em>
4(1) + b = 29 , <em>b = 25</em>
<em>(b).</em> 2x³ + x² + 25x + 12 = 0
= <em>- 4</em> ( given: f(x) is divisible by x + 4 )
= <em>0.5</em>
= <em>3</em>
Answer:
25
Step-by-step explanation: 90-65=25
The origin is the point (0,0) where the x and y axis intersect. To get to the point (-1,1) start at the origin, move one unit to the left and one unit up. To get to the point (1,-1.5) start at the origin and move one unit right and down one and a half. To get to the point (2, 1/4) start at the origin and move 2 units right and up one fourth of the way to 1.
Part a will equal 0.05 and part b is 2.2125
