Well, 10 can go into 56, 5 times, so your whole number would be 5.
Then 50 (where did i get 50 from? 5 times the ten is 50) minues 56 is 6. So it would be :
5 and 6/10 (your denominator stays the same)
But it needs o be simplafied to its lowest terms. They are both divisable by 2, SOO 6 divided by 2 is 3, and 10 divided by 2 is 5 So, your new fraction is:
5 and 3/5 in which it cant be simplafied anymore.
<em>~ 5 3/5 </em><em>is your answer :)</em>
the slope would be the change in Y over the change in X,
-7-1= -8, 3-(-1)= 4, -8/4 or -2 is the slope
Answer:
C
Step-by-step explanation:
converting 8 ft to inches
8 * 12 = 96inches
if 96 inches = 443.2 m
1 inch = (443.2 * 1)/96 = 4.6m
which is closest to option c
Because of the relatively large coefficients {9, 42, 49}, applying the quadratic formula would be a bit messy. Instead, I've chosen to "complete the square:"
9x^2 + 42x + 49 = 0 can be re-written as 9 [ x^2 + (42/9)x ] = -49
Dividing both sides by 9, we get [ x^2 + (42/9)x ] = - 49/9
Completing the square: [ x^2 + (42/9)x + (21/9)^2 - (21/9)^2 ] = -49/9
[ x + 21/9 ]^2 = 441/81 - 441/81 = 0
Then [ x + 21/9 ] = 0, and x = -21/9 (this is a double root).
The answer is g(x) = x^2 + 13x + 30
You can get this is multiple ways. Firstly, you could factor to find the zeroes and then move the answers to the left and redistribute the parenthesis.
You could also put the equation into vertex form and shift the number inside the parenthesis by 4.
Either will give you the exact same answer.
