The three angles make a total of 180
(2x+7) +(3x+2)+41=180
5x+50=180
5x=130
x=26
so angle B is 2*26+7=59 degree

We can still have some fun with answer choice <span>x = 1, x = 3:
An associated quadratic function would have the form y = a(x-1)(x-3). Just supposing that the point (2, 5) were on the graph, then this </span>y = a(x-1)(x-3) would become 5 = a(2-1)(2-3), or 5 = a(1)(-1), or 5 = -a, or a = -5.
Thus, the equation of the parabola would be y = -5(x-1)(x-3), or, in the more usual form, y = -5(x^2 - 4x + 3).
Complete the square to find the vertex:
Steal y = x^2 - 4x + 3 for a moment and complete the square:
x^2 - 4x + 3 = x^2 - 4x + 4 - 4 + 3, or (x-2)^2 - 1
Subbing this back into y = -5(x^2 - 4x + 3), we get
y = -5 [ (x-2)^2 -1 ], or y = -5(x-2)^2 + 5. This shows that the vertex is at (2, 5), that the graph opens downward, and the graph is symm. about the line x = 2.
Having fun yet?
Answer:
3) y = 2
Step-by-step explanation:
Step : 1
given 2 y-1 =3
Adding '1 ' on both sides, we get
2 y -1 +1 = 3+1
2 y = 4
dividing by '2' on both sides, we get
cancelling '2' on both sides, we get
y = 2
Answer:
The population one year from now would be 103,500,000
Step-by-step explanation:
The current population is 100,000,000
Growth rate of 3.5%.
So the population one year from now is 3.5% of the current population(100,000,000) added to the current population(100,000,000).
3.5% of 100,000,000 is 0.035*100,000,000 = 3,500,000.
Added to 100,000,000
100,000,000 + 3,500,000 = 103,500,000
The population one year from now would be 103,500,000
X plus y plus z equals 180. A triangles angles should ALWAYS add to 180. No ands or buts.
