Answer:
I believe the slope of question 6 is zero
Step-by-step explanation: This is becaucse it horizontal to the y-axis
7x +3 you add like terms which is 2x, and 5x that equals 7x the y’s cancel out. Then all you have left is 3
Answer:
-3(3z+91)
Step-by-step explanation:
Hope this helps :)
−12(7z+4)+15(5z−15)
= -3(4(7z+4)-5(5z-15)
= -3(28z+16-25z+75)
= -3(3z+91)
Answer:
The error she made was that she was adding x and 2.75. She should subtract 2.75 from x.
Another mistake that she made was that she sold each for $7 assuming that she would make a profit of 78, but she should see each necklace for $12.5 so that she could make a profit of $78.
Step-by-step explanation:
The error she made was that she was adding x and 2.75.
She should write the equation as 8 (x - 2.75) = 78; as she spends $2.75 to make a necklace.
By using the correct equation: 8 (x - 2.75) = 78
=> 8x - 22 = 78
=> 8x = 78 + 22
=> 8x = 100
=> x = 100/8
=> x = 12.5
Another mistake that she made was that she sold each for $7 assuming that she would make a profit of 78, but she should see each necklace for $12.5 so that she could make a profit of $78.
Hope this helps you.
