Write the equation of the line, given the y- and x-intercepts.
Archy [21]
The formula would be:
<span>y = mx + b
</span><span>
Now, let's look at the information we know. 
m = slope 
b = y-intercept
y-intercept = -6
x-intercept = -2
</span>
First, we would need to determine the slope. The formula for slope is m = \frac{ y_{2} - y_{1} } { x_{2} - x_{1} }

Plug your coordinates in and solve it. 
\frac{0 + 6}{-2 - 0} = 6/-2 = -3

Now, since we have the slope and y-intercept, we are ready to plug them into the formula. 
y = -3x - 6

I hope this helps!

If you start at vertex A and use the "shortest route" algorithm, what would be the second path to
MAVERICK [17]

Answer:

Shortest distance=|AC|/\sqrt[2]{2}.

Kindly find the attached for the figure

Step-by-step explanation:

This problem can be addressed using right-angled,

Let have right angle triangle with the shortest distance=hypotenuse;

hypotenuse=|AC|

using pythagoras theorem, we have

|AC|^2=|AB|^2+|BC|^2

Let |AB|=|BC|

|AC|^2=2|AB|^2

|AB|=|AC|/\sqrt[2]{2}

Shortest distance=|AC|/\sqrt[2]{2}

12x + 7 &lt; -11 AND 5x – 8 &gt; 40
statuscvo [17]

Answer:

x and x> 9\frac{3}{5}

Step-by-step explanation:

12x+7<-11 subtract 7 from both sides 12x<-18 divide both sides by 12 x<1.5

5x-8>40 add 8 to both sides 5x>48 divide both sides by 5 x>9.6

Use simple interest to find the ending balance​
Elena-2011 [213]
Answer: 7788.50

Solving steps:
P = 7400, R = 10.5%, T = 6

F = P + P rt
P = 7400
R = 10.5%
T = 6

F = 7400 + 7400rt

7400 x (12 + 6 x 0.105/12

7400 x (12 + 0.63)/12

7400 x 12.63/12

93462/12
