Answer:
k=2
Step-by-step explanation:
We have got a right triangle LNO with sides = m,4 and 8
By Pythagorean theorem
m^2=4^2 +8^2
Or m^2 = 80 ... i
IN triangle NOM, 4^2 +k^2 = l^2
i.e. 16+k^2 = l^2... i
In triangle LNM, m^2+l^2 = (8+k)^2
Substitute for m^2 as 80,
i.e. 80+l^2 = 64+k^2 +16k ... iii
From i, l^2 = 16+k^2
Substitute in iii
80+16+k^2 = 64+k^2 +16k
16k = 32 or k =2
36.89 / 8.6 ≈ 4.29
Hope this helps!
Overestimate because then the gardener could possibly save the left overs in case they get a chance to use it or they could give it to someone who may need it.
Plot and connect the points A(6,-7), B(1,-7), C(1,-4), D(3,-2), E(7,-2), F(7,-4), and find the length of DE

The length is 4 units...
They share the same value of y so the length would be | 7 - 3 | = 4
Answer:
4x-5y=-10
Step-by-step explanation:
The standard form of a linear equation is Ax+By=CAx+By=C.
Multiply both sides by 55.
5y=5(45x+2)5y=5(45x+2)
Simplify 5(45x+2)5(45x+2).

5y=4x+105y=4x+10
Rewrite the equation with the sides flipped.
4x+10=5y4x+10=5y
Move all terms containing variables to the left side of the equation.
4x−5y+10=04x-5y+10=0
Subtract 1010 from both sides of the equation.
4x−5y=−104x-5y=-10
