14x + 6 = 10 + 14x - 4

14x + 6 = 14x + 6

infinitely many solutions because both sides of the equation are equal

if Jazzy sells her old bike for $104 and some toys for 68 she uses the money for four month karate lessons the cost of lessons is the same each month which strip diagram shows how to find Jazzy's cost for one month of karate lessons.lend a hand please also this is 4th grade

Answers

Answer:

C

Step-by-step explanation:

She sells her bike for 104 dollars

She sells toys        for  68 dollars

Total                             172

The question is a bit ambiguous. There are 4 divisions. So I would assume that you need to divide 172 by 4. If you do that you get 43

I think that what they are getting at is the answer is C. There are 4 months shown. And 1 month would be 43 dollars. She has enough for 3 more months.

How can you find the slope of the line that passes through the points (0, 0) and (2, 4)? Explain.

Answers

The slope formula is y2 - y1 / x2 - x1.

We have two points:

(0,0) (2,4) and points are written in the form (x,y).

From this information we can determine:

y2 = 4
y1 = 0
x2 = 2
x1 = 0

Substitute these into the slope formula:

y2 - y1 / x2 - x1

4 - 0 / 2 - 0

4 / 2

Slope = 2

The slope of the line that passes through the points (0, 0) and (2, 4) is m = 2

The slope(m) of the line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

For the line that passes through the points (0, 0) and (2, 4)

x₁ = 0, y₁ = 0, x₂ = 2, y₂ = 4

Substitute x₁ = 0, y₁ = 0, x₂ = 2, y₂ = 4 into the equation [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m = \frac{y_2-y_1}{x_2-x_1} \\\\m = \frac{4-0}{2-0} \\\\m = \frac{4}{2} \\\\m = 2[/tex]

The slope of the line that passes through the points (0, 0) and (2, 4) is m = 2
