Step-By-Step Explination:
First you find out what x is by doing 42 multiplying it by 0.1 witch equals 4.2 gallons per mile
Next you figure out what y is by doing 4.2y (witch is 4.2 times y)
35x - 63 + 4x
35x + 4x -63
39x - 63
Answer:
To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect. The two lines intersect in (-3, -4) which is the solution to this system of equations. I hope this helped!
Answer:
<h2>-2√3 + 2√15</h2>
Step-by-step explanation:
√3 (-2+√20) = √3×(-2) + √3×√20
= -2√3 + √3×√(4×5)
= -2√3 + √3×√4×√5
= -2√3 + √3×2×√5
= -2√3 + 2√15
