Answer:
20 blocks per pound.
Step-by-step explanation:
In this question we have to determine the approximate number of blocks per pound, means we have to determine the slope of the given line in the graph.
Here end points of the line are origin (0,0) and (5,100).
Now the slope will be m = (y - y')/(x - x') = (100-0)/(5-0) = 100/5 = 20
Therefore the answer will be 20 blocks per pound.
Answer:
20 blocks is the answer
Step-by-step explanation:
-4.2 - 0.72x
-0.72x + (-4.2)
-4.2 + 0.72x
-4(0.18x + 1.05)
0.6(-7) - 0.6(-1.2x)
0.6(-7) + 0.6(-1.2x)
The correct options are B, C, E, and G.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
0.6(-7 - 1.2x)
The value of the expression
Therefore any expression equal to this will be the equivalent expression
A.) -4.2 - 1.2x
As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.
B.) -4.2 - 0.72x
This expression will be equal to the desired expression. Thus, this is an equivalent expression.
C.) -0.72x + (-4.2)
On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.
D.) -4.2 + 0.72x
As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.
E.) -4(0.18x + 1.05)
On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.
F.) 0.6(-7) - 0.6(-1.2x)
As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.
G.) 0.6(-7) + 0.6(-1.2x)
On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.

Answer:
-4.2 - 0.72x (second)
-0.72x + (-4.2) (third)
-4(0.18x + 1.05) (fifth)
0.6(-7) + 0.6(-1.2x) (seventh)
Step-by-step explanation:
okay so 0.6(-7 - 1.2x) = -4.2 - 0.72x or -0.72x - 4.2 or -4.2 + (-0.72x) or -0.72x + (-4.2) they are all the same meaning these are all the simplified answers
so the first one is incorrect because it is -4.2 - 1.2x (simplified)
the second one is correct because it is -4.2 - 0.72x (simplified)
the third one is correct because it is -0.72x - 4.2 (simplified)
the fourth one is incorrect because it is -4.2 + 0.72x (simplified)
the fifth one is correct because it is -0.72x - 4.2 (simplified)
the sixth one is incorrect because it is -4.2 + 0.72x (simplified)
the seventh one is correct because it is -4.2 - 0.72x (simplified)
Answer:
y = -3
Step-by-step explanation:
9x + 7y = -12
Let x = 1
9 (1) + 7y = -12
9 + 7y = -12
Subtract 9 from each side
9 -9 + 7y = -12-9
7y = -21
Divide each side by 7
7y/7 = -21/7
y = -3
Answer:
y = -3
Step-by-step explanation:
9x + 7y = -12
9(1) + 7y = -12
9 + 7y = -12
7y = -12 - 9
7y = -21 (divide both sides by 7)
y = -3
Answer:
A trinomial with a leading coefficient of 3 and a constant term of -5 is .
Step-by-step explanation:
To find : A trinomial with a leading coefficient of 3 and a constant term of -5 ?
Solution :
A trinomial is a polynomial with three terms is in the form of .
where, a is the leading coefficient, b is the middle coefficient of x and c is the constant.
A trinomial with a leading coefficient of 3 and a constant term of -5.
Here, a=3,c=-5 and consider b=1,
So,
Therefore, a trinomial with a leading coefficient of 3 and a constant term of -5 is .
A trinomial with a leading coefficient of 3 and a constant term of -5 can be represented as 3x^2 + 4x - 5, where 3 is the leading coefficient and -5 is the constant term.
In mathematics, a trinomial is an algebraic expression made up of three terms. In your case, you are asking for a trinomial with a leading coefficient of 3 and a constant term of -5. An example of such a trinomial could be 3x2 + 4x - 5. Here, 3 (the coefficient of the x2 term) is the leading coefficient, and -5 (the term without any variable) is the constant term.
