If you need to substitute the equation x = y - 1.
If you have another equation, then you would plug in y - 1 into the x value of the equation you would need to substitute into.
Hope this helps
The slope-intercept form: y= mx + b
m - slope
b - y-intercept
The formula of a slope:
We have the points (6, 2) and (5, 5). Substitute:
Therefore we have y = -3x + b.
Put the coordinates of the point (5, 5) to the equation:
5 = -3(5) + b
5 = -15 + b <em>add 15 to both sides</em>
20 = b
<h3>Answer: y = -3x + 20</h3>
Answer:
50 Degrees
Step-by-step explanation:
Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.
First 3x52 = 156 then 156x10 = 1560
One way of calculating decimal sum is by using partition
8.3 = 8 + 0.3
5.2 = 5 + 0.2
4.36 = 4 + 0.3 + 0.06
42.1 = 42 + 0.1
86.0 = 86
Add the units together: 8 + 5 + 4 + 42 + 86 = 145
Add the tenth together: 0.2 + 0.3 + 0.3 + 0.1 = 0.9
Add the hundredth together: 0.06 (we only have one value in hundredth)
Then add all the answers together: 145 + 0.9 + 0.06 = 145.96
Answer 145.96 is correct to two decimal places
If we want to round this answer to correct significant figures, it would depend on how many significant figures are asked.
For example:
145.96 to one significant figure is 100.00
145.96 to two significant figure is 150.00
145.96 to three significant figure is 146.00
and so on
Correct answer: 146.00 (answer is rounded to three significant figures)
