X + 2y = 10 . . . (1)
6y = -3x + 30 . . . (2)
From (2), 3x + 6y = 30
3(x + 2y = 10)
3 x (1)
Since, the second equation is a multiple of the first equation, the system will have an infinitely number of solutions.
Answer:
16
Step-by-step explanation
6 = x/4 + 2
subtract 2 from both sides
4 = x/ 4
since its dividing x and 4 you need to multiply 4 on both sides
16 = x
Answer:
Yes, the given table represent an exponential function.
Step-by-step explanation:
Given table is :
x y
1 4
2 16
3 64
4 256
Now we need to identify if the given table represent an exponential function or not. To find that we need to check if we can write the numbers in y-column in form of exponential function 
.
We see that y-values are basically powers of 4 so we can write the related function as 
.
Which is clearly in form of .
Hence yes, the given table represent an exponential function.
We are given with two equations 2x − 3y = −1 and <span>11x − 9y = −13. The problem says that when the first equation is multiplied by -3 which results to -6x + 9y = 3, the sum of the resulting equation and the second one is equal to 5x = -10. We verify this: -6x + 11x = 5x while -9 y and 9 y cancels out. 3+-13 equals -10. Hence the total is really 5x = - 10.</span>
Answer:
Which of the following is a linear function?
- y = x^3 + 1
- (5/6)x = y − 4
- y = 8x^2
- y =(1/5)x
<u>2. (5/6)x = y − 4 and 4. y =(1/5)x</u> are the right answers.
Step-by-step explanation:
Linear function is in the form <u>y=ax+b</u><u>.</u>
