Answer:
<h2>y = -3x - 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
We have two points (1, -4) and (-2, 5).
Substitute:
Substitute the value of a slope and the coordinates of the point (1, -4) to the equation of a line:
<em>add 3 to both sides</em>
Finally:
The Answer is....
x=-3 and y=3
(-3,3)
Answer:
9, 30, 27
Step-by-step explanation:
To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.
So, we must add the sides to get 66 feet.
n+3n+3+4n-9=66
Combine like terms, and solve:
(n+3n+4n)+(3+-9)=66
8n+-6=66
8n-6=66
n=9
So if n=9, we can easily find the value of the other sides.
3(9)+3=30 feet.
4(9)-9=27 feet
So, the sides are 9, 30, and 27 feet (in order).
Answer:
a,c,and e
Step-by-step explanation:
8(highest)+535(lowest)=543
an easy way to get the answer is to just add the two numbers together because your just trying to find how far it is between -535 and a positive 8.
