Find an equation of the line passing through the points (−8,2) with the slope m= 4/3

Nimfa-mama [501]3 years ago

Answer:

y=\frac{4}{3}x+\frac{38}{3}

Step-by-step explanation:

So we want to find an equation of a line passing through (-8,2) with a slope of 4/3.

To do so, we can use the point-slope form. This is:

y-y_1=m(x-x_1)

So, substitute (-8,2) for x₁ and y₁, and let m be 4/3:

y-2=\frac{4}{3}(x+8)

Distribute the right:

y-2=\frac{4}{3}x+\frac{32}{3}

Add 2 to both sides. Note that 2 can be written as 6/3. Thus:

y=\frac{4}{3}x+\frac{32}{3}+\frac{6}{3}

Simplify:

y=\frac{4}{3}x+\frac{38}{3}

And this is our equation :)

Fudgin [204]

Answers with step-by-step explanation:

1. (7x + x) + 7x

= 7x + 7x + x

= 14x + x

= 15x

2. 5 * (4 * x)

= 5*4x

= 20x

3. 15y + (x + 9y)

= 15y + 9y + x

= 24y + x

4. (6x + 21) + 14

= 6x + 21 + 14

= 6x + 35

5. 3x + 2 + 11x

= 11x+ 3x + 2

= 14x + 2

6. (x + 13y) + 8y

= 13y + 8y + x

= 21y + x

7. (12y + 2x) + 4y

= 12y + 4y + 2x

= 16y + 2x

8. 8 (x4)

= 32x

9. 3 (5x)

= 15x

10. 3x + (7x + 10)

= 3x + 7x + 10

= 21x + 10

11. 5x + (2 + x)

= 6x + 2

12. 4 * x * 10

= 4 * 10 *x

= 40x

13. (x * 12) * 3

= 36x

14. 14x + 9y + 6x

= 20x + 9y

15. 5x + (24 + 14x)

= 19x + 24

If represents the number of bacteria in a culture at time t, how many will there be at time
Crazy boy [7]

Answer:

Population of bacteria at  time t = 6 is 2441

Step-by-step explanation:

The complete question is

If y = 10 (2.5)^trepresents the number of bacteria in a culture at time t, how many will there be at time t = 6

Solution

Given

The population of bacteria after time t is equal to y = 10 (2.5)^t

Population when at time t = 6

We will substitute the value of time in above equation.

y = 10 (2.5)^6\\y = 10  *244.14\\y = 2441.4 = 2441
