I do know the bottom one is 2.8
Top is 1.6
I don’t know the middle one
Assuming that Ralph budgeted $180 instead of $175 entertainment. He spent $35 per date and let "x" be the number of dates he attended. He spent $15 to go out with friends and let "y" the number of times that he go out with friends.
The correct expression is the "B" which is 35x + 15y =180.
Hello,
ρ=√(4²+3²)=5
tan θ=-3/-4=3/7
==>θ=216,869897...° (since θ is in the III quadrant)≈216.9°
Answer C
In a standard binomial equation: ax² + bx + c = 0
To complete the square; divide the middle coefficient "b" in half and square it to find "c".
(-5/2)² = 25/4
x² - 5x + 25/4 = 25/4
completes the square:
(x - 5/2)² = 25/4
