The slope intercept form looks like y=mx+b (m-slope, b is the y intercept)
y+3=1/2(x-2)
y=(1/2)x-(2/2)-3
y=(1/2)x-4
X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
Answer:
<h2>D</h2>
Step-by-step explanation:
<h3>:))))))))))))))))))))))))))))))))</h3>
30(-2/5)²(5/8) = 30*(4/25)*(5/8) = 30*4/(5*8) = 3
We can use the Pythagorean Theorem to solve for side AB
a^2+b^2=c^2
a will be 6 and b will be 8 becuase those are the legs
6^2+8^2=c^2
36+64=c^2
100=c^2 (square root both sides)
c=10
Then we find the difference between 10 and 6 because 6 is the shortest leg
10-6=4 ft. so B
Hope this helps
