Answer:( -13,2)
Step-by-step explanation:
Answer:
4th option
Step-by-step explanation:
note that y = f(x)
locate f(x) = 1 ( output) on the y- axis, then a horizontal line passing through y = 1 intersects with the curve at (- 7, 1 ) and (2, 1 )
the input is then the x- coordinates of these 2 points , that is
x = - 7 and x = 2
Answer: choice A) x = 60, y = 30
==================================================
Focus on the smaller triangle on the left side. This is an equilateral triangle with all angles the same measure. So we have three angles each x degrees. They add to x+x+x = 3x. Set this equal to 180 (all angles of any triangle add to 180) and solve
3x = 180
x = 180/3
x = 60
Since all three angles of that triangle are each 60 degrees, this means that the base angle of the smaller triangle on the left is y = 90 - x = 90 - 60 = 30.
Put another way, x+y = 60+30 = 90 because the angles x and y form the 90 degree right angle. See the attached image for more info.
note: the triangle on the right side is an isosceles triangle. The base angles are congruent, and these angles are opposite the congruent sides (marked with the tickmarks).
Answer:
Step-by-step explanation:
2/3 + 1
-- If the 3rd side is less than 6, it could never reach between the ends of the 10 and the 16.
-- If the 3rd side is more than 26, then the 10 and the 26 could never reach its ends.
So the 3rd side must be longer than 6 and shorter than 26.
<em>6 < x < 26</em>
