Answer:
yes they can
Step-by-step explanation:
The answer is : y=-6-47
:)
There is an easy way to find y intercept. I can tell you how and show you the answer
1 {Y Intercept = 3 } [ This is where the line crosses the line going from up to down in the middle. ]
{slope = 2/1 } To find the slope you find a place where the slanted line is perfectly on the graph.:
You then go up. { GO UP FIRST! that will be the number on top. Stop when you notice the slanted line to the right is exactly on the graph. So what i did is started at (-1, 1) Then went up twice. I saw that to the right of me was the slanted line which was exactly on the graph. So I went up twice [2] then went right once [1]
To find your equation you just put y= [ y intercept form ] and your numbers you found.
y=2/1x + 3
Make sure you have x after your slope so you know it is always going up, no matter what number you put inside.
IF YOU WANT ME TO DO THEM ALL COMMENT. I WILL DO THEM ALL WITHOUT EXPLANATION.
** NOTE ** If the line is decreasing from the left. “\”it is negative so the slope will me - you will do that for your next question
Answer:
16 feet
Step-by-step explanation:
We use Pythagorean Theorem to find the height.
leg of triangle= height of ladder = 15 feet
The hypotenuse of the formed triangle = length of ladder = L
base = 6 feet
What is length of ladder?
L^2 = 15^2 + 6^2 = 225 + 36 = 261
L = root(261) = 16.155 feet
A shorthand method of writing very small and very large numbers is called scientific notation, in which we express numbers in terms of exponents of 10. To write a number in scientific notation, move the decimal point to the right of the first digit in the number. Write the digits as a decimal number between 1 and 10.
