Answer:
Yes
Step-by-step explanation:
B is a subset of A because if A= {0,1,2,3,4} and B= {1,2} B is a part of A and B is a smaller version of A
Don't know if this helps but this is how I learned subsets.
9.5 because 9.5-7 is 2.5. 2.5 times 4/5 is 10/5 which is equivalent to 2. 4/5(2.5-7)=2
For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.
Answer:
I have no clue as to what the options were, but the answer is 61 and three-fifths.
Step-by-step explanation:
<em>Well, the fraction options were a little distorted, so I'll work it out anyway.</em>
<em />
7 • 8 4/5
7(8 + 4/5)
<em>7 • 8 is 56, and 7 • 4/5 is 28/5.</em>
56 + 28/5
<em>28/5 as a mixed-number fraction (I think that's what it's called) is 5 3/5.</em>
56 + 5 + 3/5
61 + 3/5
61 3/5 (61 and three-fifths)
There!
<em>(Sorry about not getting the options...)</em>
Answer: -3
-3(0)-1=-1
-3(-4)-1=11
-3(-6)-1=17
I hope this is good enough:
