7x - y= -5. Standard form is when it is written with x and y on the same side, but x is not negative or a fraction. To find the slope and y intercept, you must change the first two equations to slope intercept. You get y=7x-5 for the first one and y=11/3x+5 for the seccond equation. Take the 5 as your y intercept and the 7 as your slope and you get y=7x+5. Now you need to change it into standard form. When all is said and done, your final answer should be 7x - y = -5.
<u>Answer:</u>
The answer is D : 4.
<u>Step-by-step explanation:</u>
<em>=2x-3>11-5x</em>
<em>=2x-3+5x>11</em>
<em>=7x-3>11</em>
<em>=7x>11+3</em>
<em>=7x>14</em>
<em>=7x/7>14/7</em>
<em>=x>2</em>

<em>By simplifying the problem, you can see that "x" </em><em><u>must</u></em><em> be greater than 2. Therefore, eliminating all other possible answers that are shown, but 4. </em>

The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches
The dimension of the mirror is given as:
From the center of the mirror to the floor of the wall, the distance is:
So, the distance to the top of the mirror will be:
Substitute 24 for height
Convert feet to inches
The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.
So, we have:
Convert feet to inches
Hence, the distance is 21 inches

Answer:
Answer is $10,144.50
Step-by-step explanation:
15% of 220 =33
220- 33 = 187
8.5% of 187 =15.89
187+15.89=202.89
202.89 x 50 =10,144.50
