When −46+87+46 is rewritten as −46+46+87, it shows that only change in positions of 87 and 46.
Change in order of sum of numbers doesn't change the result.
And when only order changes of added numbers, it will be a Commutative Property of Addition.
This propery could be shown by a simple expression
a+b = b+a.
So, first answer will be "The property used to rewrite this expression is the <u>Commutative Property of Addition.</u>
Now, let us evalute the expression by applying order or operations.
According to order of operations, we would could go from left to right.
−46+46+87.
So, first we add -46+46 = 0 ( by Additive inverse property )
0+87 = 87 ( by Identity Property of Additon) .
Therefore, answer for second part is ..
When the expression is evaluated, the solution is<u> 87.</u>
Answer:
A and D
Step-by-step explanation:
I could be wrong but the solutions are the points of intersection between the two functions. By looking at it. I can see that its about -3.3 and 5.2
Hope this helps!
Given:
The expression is 2(-9x+21) - (14-10x).
Explanation:
Simplify the expression by using distibutive property of multiplication.
So equivalnet expression is,
-8x + 28
Solution:
<u>Note that:</u>
- Slope = m = 4
- Given point: (x₁,y₁) = (1,1) [x₁ = 1; y₁ = 1]
- Formula: y - y₁ = m(x - x₁)
<u>Use the formula to convert the line in point slope form.</u>
- y - y₁ = m(x - x₁)
- y - 1 = 4(x - 1)
The equation of the line (In point slope form) is y - 1 = 4(x - 1).
Answer:
154
Step-by-step explanation:
11 * 14
= 154
