Answer:
A
Step-by-step explanation:
The Explication 0 (7+4i)+(7-4i) = 14
I got 5. If you divide 210 by 3, you get 40 miles an hour. You then divide 200(miles) by 40(how fast your going) to get 5.
Answer:
<em>y = x ÷ 2</em>
Step-by-step explanation:
We are given a table of values, which will be represented as ordered pairs (x,y) below:
(2,1) (4,2) (8,4) (10,5) (16,8)
We are required to select one of the functions that match the numeric relationship between x and y.
We could test them one by one, but at simple observation, we can note the values of y are half of the values of x:
2/2=1
4/2=2
And so on. Thus the only function that divides the value of x by 2 to find the value of y is:
y = x ÷ 2
You can go through the set and test each one out:
x=0:
2(0)+3 ≥ 7? Or 3≥7? No
x=0.6:
2(0.6)+3≥7? 4.2≥7? No.
x=2:
2(2)+3≥7? 7≥7? Yes.
x=4:
2(4)+3≥7? 11≥7? Yes.
x=6:
2(6)+3≥7? 15≥7? Yes.
The set is {2, 4, 6}.
Answer:
c) <u>m = 5p-4</u>
Explanation:
Given that function A is : x → +4 → ×2.
A(x) = 2(x+4).
Given that function B is: x → ÷5 → +1.
B(x) = x/5 + 1.
To find the working variables for:
m → Function A → Function B → 2p + 1.
Create this composite function: B(A(x)) = 2(x+4)/5 + 1
Then set x equal to m and solve for the working equation to 2p + 1
_______________
(simplify)
2(m+4)/5 + 1 = 2p + 1
-1 -1
________________
2(m+4)/5 = 2p
÷2 ÷2
___________
(m+4)/5 = p
×5 ×5
_________
(m+4) = 5p
-4 -4
________
<u>m = 5p - 4</u>
