Answer:23,87
Step-by-step explanation:
call the 2 numbers x and y
average of 2 numbers being 55 means (x+y)/2 = 55
if the positive difference of the two numbers is 64 then x-y=64
since you have two equations and two variables you can solve for x and y
(x+y)/2 = 55 --> x+y=110
x-y=64 --> x=64+y
x+y=110 and x=64+y --> 64+y+y=110
y=23
x=87
the two numbers are 23 and 87
It add by the number in the first column.
1 + 1 = 1
2+1=3
3+2=5
5+4=9
Answer: C, 20
33 - 3 = 30
^the three who like both
x + 2x = 30
^students who only like computing
^students who only like PE
3x = 30
x = 10, so twice that is 20.
*hope i explained it well!!
Answer:
1978$
Step-by-step explanation:
Hope you day is going well!
So we are given the following function: .
Before we can solve this problem, we need to know the following:
- Given g (x) = f (x) + k; The graph of g(x) equals f(x) shifted k units vertically. If k > 0, the base graph shifts k units upward, and if k < 0, the base graph shifts k units downward.
- Given g(x) = f (x - k); The graph of g(x) equals f(x) shifted k units horizontally.
If k > 0, the base graph shifts k units to the right, and if k < 0, the base graph shifts k units to the left.
- The reflection of the point (x,y) across the x-axis is the point (x,-y).
- The reflection of the point (x,y) across the y-axis is the point (-x,y).
Know we can solve the problem!
1. . <em>Translated left by 2 units. </em>
2. <em>Translated down by 2 units</em>
3. <em>Reflected across the x-axis and the y-axis </em>
4. <em>Translated up by 2 units </em>
5. <em>Translated right by 2 units</em>
6. y = (x + 2)2 <em>Reflected across the x-axis</em>
