Answer:
x < -7
Step-by-step explanation:
-5x + 7 > 42
Subtract 7 from each side
-5x + 7-7 > 42-7
-5x > 35
Divide each side by -5, remembering to flip the inequality
-5x/-5 <35/-5
x < -7
Answer:

Answer:
Yesenia has qty 1 of 10s and qty 7 of 1s
Misty has qty 6 of 10s and qty 8 of 1s
<u>Step-by-step explanation:</u>
Note that there are two different types of blocks: 1s and 10s. Let x represent the number of 10s and y represent the number of 1s.
<u>Value of the blocks </u> <u>Number of blocks</u>
Yesenia: 1x + 7y 8
Misty: <u> </u> <u> </u>
Total: 8x + 5y 22
Start with the number of blocks that Misty has: 22 - 8 = 14
Next, how many 1s can be added to Yesenia's to make 5? 15 - 7 = 8
How many blocks are left over from Misty's 14? 14 - 8 = 6
********************************************************************************************
Fill in the information:
<u>Value of the blocks </u> <u>Number of blocks</u>
Yesenia: 1x + 7y 8
Misty: <u> 6x + 8y </u> <u> 14 </u>
Total: 8x + 5y 22
Answer:
-6
Step-by-step explanation:
f(x) = -x-1
Find f(5), <u><em>this means that anywhere you see </em></u><u><em>x</em></u><u><em>, you substitute in </em></u><u><em>5</em></u><u><em>.</em></u>
f(x) = -x-1
f(5) = -(5)-1
<u>Take note of the signs.</u>
f(5) = -6
