Where is the picture lolzzzzz
You re write the equation, so when the equations are added one of the variables are eliminated
In order to answer this one, it's really really really really helpful if you know what the law of cosines says. In fact it's absolutely necessary.
The law of cosines says if you know two sides of a triangle and the angle between them then you can use that information to find the length of the third side.
In the picture you know the lengths of two sides and you know the angle between them. So you can use the law of cosines to find the length of the third sidethat. That's side AC.
Answer:
x + 3y = -12
Step-by-step explanation:
y = mx + b
m is the slope = rise / run:
rise = 1
run = 3
the line is downhill so its negative
m = - 1 / 3
b is the y intercept which is when the line cross over the y axis: - 4
y = - 1/3x - 4
multiply both sides by 3
3y = -1x - 12
add x to both sides
x + 3y = -12
<span>Presumably, the opposite of decimals are fractions because by dividing the two numbers you get the decimal value of the fractional form of the number. Refer to the example below.
How do you write 39/100 into a decimal form is by simply dividing 39 to 100. </span>
<span>Hence, </span>
1. 39 / 100 = 0.39 -> Hence this is the decimal form.
<span>0.39 is the decimal form of the given value. </span>
<span>Other examples can include: </span>
<span><span>1. </span> 100 / 1000 = 0.1</span> <span><span>
2. </span> 45 / 10 = 4.5</span><span>
