Consider lines ℓ = {(x, y)|〈x, y〉 = 〈1,1〉 + t〈1, −2〉} and m = {(x, y)|〈x, y〉 = 〈1,1〉 + t〈−1,3〉}.
a. what is the solution to the system of equations given by lines ℓ and m?
b. describe what happens to the lines under the transformation a = 1
2 1

c. what is the solution to the system of equations after the transformation?

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465
