Step-by-step explanation:
1- 6(x+8)=5x+4. First calculate the brackets.
2- 6x+48=5x+4 (multiply the number in front of the brackets with the numbers in the brackets) so 6×X= 6x and 6×8= 48
3- 6x-5x= -48+4 put the numbers with x on the left hand side and the others on the right hand side. (when moving from side to the other side you convert + into - or reversed)
4- x= -44 now work out the sums and then you get x

Answer: Choice D. (6,12)</h3>
Explanation:
The translation
tells us to add 1 to the x coordinate and subtract 1 from the y coordinate.
For point R(1,5) we'll arrive at R'(2,4) after applying that translation or shifting mentioned. We have moved the point 1 unit to the right and 1 unit down.
Now apply the dilation with a scale factor of 3, centered at the origin. Basically it means we triple each coordinate. We'll go from R'(2,4) to R''(6,12)
ANSWER
The correct answer is C

EXPLANATION
The ordered pair of the relation are:

The domain is the set of all the x-values for which the function is defined.
These are:

Therefore the correct option is C.
Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)
Let D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}a) find the D U Eb) find the E n F
Juli2301 [7.4K]
the given sets are,
D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}
now,
D U E = { 4 , 6, 7 , 8, 9}
and'
E intersection F = E n F = {6 , 7)
thus, the answer is
D U E = { 4 , 6, 7 , 8, 9} and
E n F = {6 , 7)
