Honestly? Just review your notes and try to work out the problems yourself before taking a look at the answer. You can also google specific topics that the test will cover and try the practice problems.
Answer:
(3, 2) is the ordered pair for the given system of equations.
Step-by-step explanation:
Given:
2 x+ y = 8.......................(i)
y = - x + 5........................(ii)
<u>Put y = - x + 5 in equation (i)-</u>
<em>2 x + ( - x+ 5) = 8</em>
<em>2 x - x + 5 = 8</em>
<em>x = 8 - 5</em>
<em>x = 3</em>
<u>Now put x = 3 in equation (ii)-</u>
<em>y = - 3 + 5</em>
<em>y = 2</em>
Hence the (3, 2) is the correct ordered pair.
1. Find angle Y. Since the interior angles of a triangle must add up to 180 deg., we have 180 - (98+24) = 58 deg.
Apply the Law of Sines to determine the lengths of sides r and t:
r 7.9 t
--------- = --------- = ---------
sin 98 sin 58 sin 24
Then r = (7.9 sin 98)/ (sin 58) = 9.22. This matches r in the 2nd choice. Determine t using the same method: t = 7.9sin 24 / sin 58.
Does your t value match that in the 2nd possible answer?
<em>PQR = 150°</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>PQR = PQS + SQR</em>
<em>12x - 6 = 16 + 9x + 17</em>
<em>12x - 9x = 16 + 17 + 6</em>
<em>3x = 39</em>
<em>x = 13</em>
<em>PQR = (12×13 - 6)° = (156 - 6)° = 150°</em>
<em>Good luck !</em>
Answer:
a.false
b.true
c.false
d.I really can't get about it.
e.false
Step-by-step explanation:
So,here;
a.9.9.3=35 is given
or,243=35 (which is false)
b.7+7+7=3+3+3+3+3+3+3
or,21=21 (which is true)
c.2/3/2=2/3
or,2*2/3=2/3
or,4/3=2/3(which is false)
e.6+6+6=63
or,18=63 (which is false)
