Answer:
True
Step-by-step explanation:
a negative number like -6 which would be found on the left of the number line is not larger than 2 which is found on the right side of the number line.
<span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>−5</span>−<span>(<span><span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>−4</span>)</span></span>
So first
Distribute the Negative Sign:
<span>=<span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>−5</span>+<span><span>−1</span><span>(<span><span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>−4</span>)
</span></span></span></span><span>=<span><span><span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>−1</span><span>(<span><span>(<span>−<span>8a</span></span>)</span><span>(b)</span></span>)</span></span></span>+<span><span>(<span>−1</span>)</span><span>(<span>−4</span>)
</span></span></span></span><span>=<span><span><span><span><span><span><span>(<span>−a</span>)</span><span>(b)</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>8a</span>b</span></span>+4</span></span><span>=<span><span><span><span><span><span>−<span>ab</span></span>+<span>8a</span></span>+</span>−5</span>+<span><span>8a</span>b</span></span>+4
</span></span>
Then after all of that
Combine Like Terms:<span>=<span><span><span><span><span>−<span>ab</span></span>+<span>8a</span></span>+<span>−5</span></span>+<span><span>8a</span>b</span></span>+4
</span></span><span>=<span><span><span>(<span><span>−<span>ab</span></span>+<span><span>8a</span>b</span></span>)</span>+<span>(<span>8a</span>)</span></span>+<span>(<span><span>−5</span>+4</span>)
So now your answer is </span></span></span><span>=<span><span><span><span>7a</span>b</span>+<span>8a</span></span>+<span>−<span>1</span></span></span></span>
Answer: 4,1
Step-by-step explanation:
Answer:
C)√
72
Step-by-step explanation:
We will Simplify the radical by breaking the radicand up into a product of known factors.
When we do this, we figure out that...
A.√
49 = 7
B.√
64 = 8
D.√
121 = 11
BUT C) is different.
√
72 can not be divided into any whole number an exact amount of times.
So instead, this can be solved by writing it as shown:
Exact Form:
6
√
2
Decimal Form:
8.48528137
Thanks for letting me help!!
4 x - 2 y = 6
2 x + y = 5 / * 2 ( we will multiply both sides by 2 )
-------------------
4 x - 2 y = 6
+
4 x + 2 y = 10
---------------------
8 x = 16; x = 2
4 + y = 5
y = 5 - 4; y = 1
In the system of equations D :
8 x = 16; x = 2 ,
8 + 2 y = 10
2 y = 2, y = 1
Answer: D ) is the equivalent system
