Answer:
true for all x
Step-by-step explanation:
3(2x-4)=6(x-2)
Distribute
6x - 12 = 6x -12
Subtract 6x from each side
6x-12 -6x = 6x-12-6x
-12 =-12
Since this is always true, there are infinite solutions
When H<G because if H is 6 and G is 7 , G is bigger than H
X = -2 and y = -5
Explanation: Solve by using the process of elimination.
Step: Solve<span><span><span>−<span>1.5x</span></span>+<span>0.3y</span></span>=1.5
Solving for x = </span><span><span><span><span>−<span>1.5x</span></span>+<span>0.3y</span></span>+<span>−<span>0.3y</span></span></span>=<span>1.5+<span>−<span>0.3y *</span></span></span></span>Add -0.3y to both sides*
<span><span>−<span>1.5x</span></span>=<span><span>−<span>0.3y</span></span>+1.5
</span></span><span><span><span>−<span>1.5x</span></span><span>−1.5</span></span>=<span><span><span>−<span>0.3y</span></span>+1.5</span><span>−1.5 *</span></span></span>Divide both sides by -1.5*
<span>x=<span><span>0.2y</span>−1</span></span>
Step: Substitute <span><span>0.2y</span>−1 </span>for x in <span><span><span><span>1.8x</span>+<span>0.9y</span></span>=<span>−8.1</span></span>:
</span><span><span><span>1.8x</span>+<span>0.9y</span></span>=<span>−8.1
</span></span><span><span><span>1.8<span>(<span><span>0.2y</span>−1</span>)</span></span>+<span>0.9y</span></span>=<span>−8.1
</span></span><span><span><span>1.26y</span>−1.8</span>=<span>−8.1 *</span></span>Simplify both sides of the equation*
<span><span><span><span>1.26y</span>−1.8</span>+1.8</span>=<span><span>−8.1</span>+1.8</span></span>(Add 1.8 to both sides)
<span><span>1.26y</span>=<span>−6.3
</span></span><span><span><span>1.26y</span>1.26</span>=<span><span>−6.3</span>1.26 *</span></span>Divide both sides by 1.26*
<span>y=<span>−5
</span></span>Step: Substitute <span>−5 </span>for yi n <span><span>x=<span><span>0.2y</span>−1</span></span>:
</span><span>x=<span><span>0.2y</span>−1
</span></span><span>x=<span><span><span>(0.2)</span><span>(<span>−5</span>)</span></span>−1
</span></span><span>x=<span>−2 *</span></span><span>Simplify both sides of the equation*</span>
Answer:
$60.9
Step-by-step explanation:
Tax = 2.9% of Cost to be bought
= 2.9 / 100 × 2100
= $60.9
The answer is c the degree of the trinomial
