Hey there! :)

Answer:

m (slope) = 3/5.

Step-by-step explanation:

Find the slope of the line using the slope formula:

$m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$

Plug in two points from the graph. We can use the points (-5, -2) and (0, 1):

$m = \frac{1- (-2)}{0 - (-5)}$

Simplify:

m = 3/5.

In the equation y = mx + b, the m value represents the slope. Therefore:

The slope of this line is 3/5.

If a seed is planted, it has a 95% chance of growing into a healthy plant. If 7 seeds are planted, what is the probability that

denpristay [2]

Answer:

$\frac{51998079}{1280000000}$ or around 0.0406

Step-by-step explanation:

We need to choose 2 seeds that will not grow - there's

7 * 6 / 2 = 21 possibilities (choose one, chose second one, divide by 2 because each choice was counted twice).

The probability of each of those possibilities happening is:

$(5\%)^2 * (95\%)^5 = \frac{2476099}{1280000000}$

because two need to fail to grow and the rest need to grow properly.

The full probability is

$\frac{51998079}{1280000000}$

The differential equation

Mazyrski [523]

As the question points out, the equation is indeed separable:

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{6x+9}{12y^2+16y+6}$

$\implies2(6y^2+8y+3)\,\mathrm dy=3(2x+3)\,\mathrm dx$

Integrate both sides to get

$2(2y^3+4y^2+3y)=3(x^2+3x)+C$

$\implies F(x,y)=\underbrace{(-3x^2-9x)}_{G(x)}+\underbrace{4y^3+8y^2+6y}_{H(y)}=C$

Find the x- and y-intercepts of<br> 5x - 3y = 12<br> .

irga5000 [103]

X = (12/5,0)
y = (0,-4)

substitute 0 in for y & solve for x , to find the y-intercept substitute 0 in for x and then solve . ( I hope that makes sense)

HELP PLEASE FIND X AND SHOW YOUR WORK

PtichkaEL [24]

Answer:

Step-by-step explanation:

Straight lines are 180 degrees, so the angle inside of the triangle next to the 127, is 53 degrees. (180-127= 53)

So to find "x", we need to figure out what the full number is.

59+53 = 112.

180-112= 68.

Now that we have the degree of the full angle, we can make an equation to find x.

x*2 = 68

(Divide 2 from both sides to isolate the variable)

x = 34

I hope this helped!
