Answer:
mm + nn = -12
mm - nn = 5
Step-by-step explanation:
two equations can be derived from the question
Answer:
Step-by-step explanation:
Putting values of x in equation
Y = 4(-3) - 4
= - 12 - 4 = - 16
Y = 4(-2) - 4
= - 8 - 4 = - 12
Y = 4(-1) - 4
= - 4 - 4 = - 8
Y = 4(0) - 4
= 0 - 4 = - 4
Y = 4(1) - 4
= 4 - 4 = 0
Y = 4(2) - 4
= 8 - 4 = 4
Y = 4(3) - 4
= 12 - 4 = 8
You divide them, so 1,125 divided by 15=25. So your Answer is 75 students are on each bus.
Answer:
(-6, -5)
Step-by-step explanation:
Reflection across the y-axis leaves the point on the same horizontal line, but with the sign of its x-coordinate changed.
(x, y) ⇒ (-x, y) . . . . . reflection across the y-axis
(6, -5) ⇒ (-6, -5)
The image point is (-6, -5).
Answer:
23.6 ft
Step-by-step explanation:
Sketch a right triangle representing this situation. The length of the hypotenuse is 26 ft and the angle of elevation from ground to top of ladder is 65°. The "opposite side" is the reach of the ladder, which we'll call x.
Then:
opp
- sin 65° = ----------
- 26 ft
or (26 ft)(sin 65°) = opp side = height off the ground of top of ladder.
Evaluating this, we get:
(26 ft)(0.906) = 23.56 ft, or, rounded off, 23.6 ft
The ladder reaches 23.6 ft up the side of the building.
