For the first blank, since the output increases by 5 for each increase of 1 for the input, the answer is 13+2(5) = 23.
For the second blank, since the output increased by 10 compared to 23, the input increased by 2. So, the answer is 5 + 2 = 7.
We know the output is of the form 5x+b for some constant b. If we test input of 1 and an output of 3, we get an input of 1 gives 5+b, which is equal to 3, meaning b=-2. So, the answer is 5x-2.

Answer:

please find the solution:

Step-by-step explanation:

please find the correct question:

Given value:

$\to 4x \equiv 2(mod\ n) \ \ \ \ \ \ \ \ \ \ \ \ _{where} \ \ n=6\\\\\to 4x \equiv 2 (mod 6)$

$\to 4x-2$ should be divisible by 6 we are also given that $0 \leq x < n$ and start with x = 0

$\to 4x-2$ =-2 which is not divisible by 6

x= 1

$\to 4x-2$ = 2 not divisilble by 6

x= 2

$\to 4x-2$ = 6 which is divisible by 6

x=3

$\to 4x-2$ = 10 not divisible by 6

x=4

$\to 4x-2$ = 14 not divisible by 6

x=5

$\to 4x-2$ = 18 which is divisible by 6

so such x are x = 2 and x = 5

Which of the following points is a solution of y > |x| + 5? A) (1,7) B) (0,5) C) (7,1)

bearhunter [10]

Answer:

Step-by-step explanation:

We can plug in all of the x and y values to check if the point is a solution to the inequality.

Point A: x = 1, y = 7

7 > |1| + 5

7 > 1 + 5

7 > 6

This is a true statement, which means that this point is a solution to the inequality. We don't have to check any more points since we have found our answer.

Can you help me explain

stepladder [879]

Answer:

x = 10

Step-by-step explanation:

We need to isolate X.

3x - 7 = x + 13

subtract 13

3x - 7 - 13 = x

combine like terms

3x - 20 = x

subtract 3x

- 20 = x - 3x

Combine like terms

- 20 = - 2x

Divide by -2

10 = x
