Find two consecutive even integers such that four times the first plus three times the second is 20

1 answer:

8 0

2 consecutive even integers : x and x + 2

4(x) + 3(x + 2) = 20
4x + 3x + 6 = 20
7x + 6 = 20
7x = 20 - 6
7x = 14
x = 14/7
x = 2

x + 2 = 2 + 2 = 4

so ur first number (x) = 2 and ur second number (x + 2) = 4

Which point below is not on the graph of p(x) = +36- X?

natka813 [3]

Answer:

We have the following equation: y = 36 - x. And we need to find which of the following points belong to the graph:

(-13,7)

(-35, 1)

(11,5)

(27,3)

If any of the points belong to the equation, then the equality will be met.

Then:

(-13,7) :

7 = 36 - (-13)

7 = 36 + 13

7 = 49 ❌

(-35, 1) :

1 = 36 - (-35)

1 = 71❌

(11, 5) :

5 = 36 - 11

5 = 25 ❌

(27,3)

3 = 36 - 27

3 = 9 ❌

None of the points belong to the graph. Therefore, all points are NOT on the grah of p(x) = 36 - x.
