Answer:

b = -3, or (0, -3)

Step-by-step explanation:

As we move from (3,1) to (6,5), x increases by 3 and y increases by 4. Thus, the slope of this line is m = rise / run = 4/3.

Starting wth y = mx + b, we substitute 4/3 for m, 3 for x and 1 for y. Doing this results in:

1 = (4/3)(3) + b, which results in b = -3. Then the equation of this line is

y = (4/3)x - 3. The y-intercept is b, and b = -3.

Answer:

(1-5)/(3-6)= -4/-3= 4/3

y - 5= 4/3(x - 6)

y - 5 = (4/3)x - 8

y = (4/3)x- 3

y-int (0,-3): -3

Find the measure of each acute angle in the figure.

Artist 52 [7]

Answer:

Angle 1 = 46°

Angle 2 = 44°

Step-by-step explanation:

Given:

Angle 1 = (4x - 2)°

Angle 2 = (3x + 8)°

Angle 3 = 90°

Find:

All acute angle

Computation:

Using angle sum property

Angle 1 + Angle 1 + Angle 1 = 180°

(4x - 2)° + (3x + 8)° + 90° = 180°

7x + 6 = 90

7x = 84

x = 12°

So,

Angle 1 = (4x - 2)° = 4(12) - 2 = 46°

Angle 2 = (3x + 8)° = 3(12) + 8 = 44°

A colony of 85 bacteria doubles in size every 126 minutes. What will the population be 378

SVETLANKA909090 [29]

Answer:

680 Bacteria

Step-by-step explanation:

378 is evenly divisible by 126, which is equal to 3.

The first 126 minutes, the 85 bacteria will double to 170 bacteria.

The second 126 minutes (252 minutes total), the 170 bacteria will double to 340 bacteria.

The final 126 minutes (378 minutes total), the 340 bacteria will double to 680 bacteria total.

It's 12 points of u get this right<br>

earnstyle [38]

Answer:

y = -2x + 8

Step-by-step explanation:

When two points are given, the equation of the line passing through the points is given by:

$\frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1}$

where: $(x_1,y_1)$ and $(x_2,y_2)$ are the two points passing through the line.

Here, $(x_1,y_1) = (2,4)$ and $(x_2, y_2) = (3,2)$ .

Substituting in the formula, we have:

$\frac{y - 4}{2 - 4} = \frac{x - 2}{3 - 2}$

⇒ $\frac{y - 4}{-2} = \frac{x - 2}{1}$

⇒ y - 4 = -2x + 4

⇒ y = -2x + 8 is the required equation of the line.
