Answer:

Step-by-step explanation:

2x - 3 is a linear expression. y = 2x - 3 is the equation describing y.

If x = 1, y = 2(1) - 3 = -1

If x = 2, y = 2(2) - 3 = 1

and so on.

Isn't there more to this problem that merely "2x - 3"?

Solve the following system of equations by the substitution method.

Masja [62]

Let

Eqn 1 be 8x = 2y + 5

And,

3x = y + 7
therefore

Eqn 2 is x= 1/3(y+7)

Sub 2 into 1 gives:

8(1/3(y+7)) = 2y + 5

8/3(y) + 56/3 = 2y + 5

2/3(y) = –41/3
2y=–41
y= –41/2

X= –9/2.

Therefore, {(-9/2, -41/2)} is your solution set. As the notation is equal to (x,y)

Nutritionists recommend that people eat

mixer [17]

The amount of grams of fiber that Jodi should eat to meet the recommended daily amount of fiber is 12 grams.

<h3>How many more grams of fiber should Jodi eat?</h3>

The first step is to convert milligrams to grams.

1 milligram = 0.001 grams

25,000 x 0.001 = 25

Now subtract the recommended amount from the quantity eaten:

25 - (8 + 4 + 1 ) = 12 grams
