Answer:
78
Step-by-step explanation:
Substitute x = - 3 into the expression
6(2(- 3)² - 5)
= 6(2(9) - 5)
= 6(18 - 5)
= 6(13)
= 78
Answer: x = -7
Step-by-step explanation: to do the problem -3x - 11 = 10, first separate the x from everything else, except the -3. To do this, you have to get rid of the 11, and since it is negative, you have to add it to both sides of the equation. This gets rid of the 11 on the left side, and adds 11 to the right side, making the right side equal 21. Last, divide -3 from both sides to get x on the left, and -7 on the right. This makes x = -7
The slope of the line is -2 and 6x + 3y = 5 also has a slope of -2
20
If you see 1/10 of it means part of it and the answer will be less.
If you see is 1/10 of it means it is part of and the answer will be more.
700,000 + 20,000 + 80
there are no exponents
hope this helps
