The equation of line passes through the points (0, -5) and (5, -2) will be;

⇒ y = 3x/5 - 5

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (0, -5) and (5, -2).

Now,

Since, The equation of line passes through the points (0, -5) and (5, -2).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 2 - (-5)) / (5 - 0)

m = 3 / 5

m = 3/5

Thus, The equation of line with slope 3/5 is,

⇒ y - (-5)= 3/5 (x - 0)

⇒ y + 5 = 3x/5

⇒ y = 3x/5 - 5

Thus, The equation of line passes through the points (0, -5) and (5, -2) will be;

⇒ y = 3x/5 - 5

Answer:

g = 28

Step-by-step explanation:

Hope this helps!!

Answer: 28

Step-by-step explanation: Look at the numerators(the top numbers). Do 8 divided by 2. That equals 4. By doing this, we know that 2 x 4 = 8. Multiply 7 by 4 to get 28. The reason why you multiply 7 by 4 is because if you multiply 4 on top, you have to multiply by 4 on the bottom.

Step-by-step explanation:

The way to get this is that you put them in fraction form 7/15 and then you make it equal to to x/100 and then divide the known part of the fraction which in this case is 100/15 which gives 6.67 (rounded). After you get that you multiply it by 7 which give you 46.69%

How many 1/4 inch cubes does it take to fill a box with width 2 3/4 inches, length 3 1/2 inches, and height 1 1/4 inches

Answers

Answer:

125 cubes brooooo gl

Step-by-step explanation:

In each side first layer for the width, 11 cubes can fit. Sine 1/4 can fit in one 4 times, 4 * 3 = 12. 12 plus 2 (2/4=1/2) is 14. So,

11 + 14 = 25.

25 is one layer. Since the height is 1 1/4 inches, multiply 25 by 5.

125 cubes bro.
