Answer:
11
Step-by-step explanation:
-4x + 7 ; x = -1
-4x (-1) + 7
4 + 7 = 11
The answer should be D
Number more than 3: 4, 5 and 6
Frequency of each number greater than three:
4- 20
5-30
6-38
Add them you get 88
Total frequency: 200
Therefore: 88/200 = 0.44
Answer:
x = -8/3
y = 4
Step-by-step explanation:
I assume you want to solve for x and y.
The best way to do this with the two formulas given is elimination. This means add the two equations together.
6x + 5y = 4
-6x + y = 20
The 6 x and -6x will cancel each other. By adding the like terms of the two together you will come out with
6y = 24
Now solve for y by dividing both sides by the 6.
y = 24/6 = 4
Now that we have y, you can plug it into one of the equations and solve for x.
Let's use -6x + y =20.
So plug in the 4 for y to get -6x + 4 = 20
Subtract the 4 from both sides then solve for y by dividing both sides by the -6.
-6x = 16
x = -16/6
You can reduce that down so that x = -8/3.
