sometimes i use a thingy called calculator soup and it should have a measurement calculator
First, find slope of point A and B using slope formula:
<u>y2-y1</u> = <u>7-0 </u>= <u>-7</u>
x2-x1 3-8 5
Next, use the point-slope formula to find the equation (pick either point A or B to substitute into this equation; the answer will be the same either way):
y-y1=m(x-x1)
y-7=<u>-7</u>(x-3) (I used point B here)
5
y=<u>-7x</u> +<u>56</u> so the y-intercept is <u>56</u>. Hurray! Part 1 down!
<span> 5 5 5
Now to answer part 2. Since AB ll CD, they have the same slope: <u>-7</u>
5
Therefore, you can use the handy point-slope equation to calculate the equation of line CD. (Remember you only need one of the points to use this equation if you already have the slope.) Since the only point given is D(5,5), we'll use that one:
</span>y-y1=m(x-x1)
y-5=<u>-7</u>(x-5)
<span> 5
</span>y=<u>-7x</u> + 12 Yay! That's the answer to part 2; the equation of line CD
<span> 5</span>
Any number that ends with a 0 or a 5 would be a multiple of 5 because as you multipy numbers by 5 you start to see a pattern in the ones place of 5,0,5,0,5,0,5,0,... And so on forever
Answer:
f^-1 (x) = √
6x/6 - √
6x/6
Step-by-step explanation:
interchange the variables and solve for y.
sorry its a little hard to read i didnt have all the symbols on my keyboard
Answer:
y = 4
Step-by-step explanation:
As we move from the point (-2, 4) to the point (3, 4), x increases by 5 units, but y stays the same. We know immediately that the slope, m = rise / run, is zero, because of this.
Both points are on the horizontal line y = 4. This answer is sufficient in itself, but could be re-written as y = 0x + 4.
