Answer:
1) x > -2
2) x < -1
Step-by-step explanation:
1) 2(x - 2) + 7 > -1
2x - 4 + 7 > -1
2x + 3 > -1
2x > -4
x > -2
2) 5 - 4x > 9
-4x > 4
x < -1
Given:
The pair of expressions in the options.
To find:
The two expressions are equivalent for any value of y.
Solution:
Two expressions are equivalent for any value of y, iff they are equivalent.
Clearly, 
is not equivalent to 
or 
. So, options A and B are incorrect.
The expression 
is not equivalent to 
. So, option C is incorrect.
The expression is equivalent to 
.
Therefore, the correct option is D.
Answer:
120 per calories I believe
Answer:
- large: 40 lbs
- small: 20 lbs
Step-by-step explanation:
A system of equations can be written for the weights of the boxes based on the relationships given in the problem statement. One equation will be for the total weight of 1 large and 1 small box; the other will be for the total weight of 70 large and 60 small boxes.
Let L and S represent the weights of Large and Small boxes, respectively. The system of equations is ...
L + S = 60 . . . . . . combined weight is 60 lbs
70L +60S = 4000 . . . . weight of boxes in the truck
__
We can solve this by substituting for s in the second equation.
70L +60(60 -L) = 4000
10L = 400 . . . . . . . . . subtract 3600, simplify
L = 40
S = 60 -L = 20
A large box weighs 40 pounds; a small box weighs 20 pounds.
Product is the multiplication of numbers. The product of the (5x-11)² is (25x²-110x+121).
<h3>What is a Product?</h3>
A product is the multiplication of a number or expression to another expression.
We know in order to find the product of (5x-11)², we need to multiply each of the terms inside the bracket to each term in the second bracket. therefore, the solution of the problem can be given as,
Hence, the product of the (5x-11)² is (25x²-110x+121).
