It should be the first one since the x and y cross each other out and leave only =-10
Answer:
30.18
Step-by-step explanation:
Answer:
C, -4
Step-by-step explanation:
slope=change in y/change in x


multiply both sides by 2/5

simplify the right side. 2/5 × 5 = 2 and 2/5 × 10 = 4


bring y to the other side by adding y on both sides

subtract 6 on both sides

so y is -4
For the 51-deg angle, y is the opposite leg, and 12 is the hypotenuse.
The trig ratio that relates the opposite leg and the hypotenuse is the sine.
sin A = opp/hyp
sin 51 deg = y/12
y = 12 * sin 51 deg
y = 9.3
Answer:
9
Step-by-step explanation:
5 x 9 is 45 plus 5 gives you 50
