Answer:
Step-by-step explanation:
2x + 3 = 1
Collecting like terms
2x = 1 - 3
2x = -2
x = -2/2
x = -1
X = 5/2 ,y = 1.I usually solve for x first then substitute the answer in one of the equations to find y.
Answer:
Step-by-step explanation:
This is a isosceles triangle, An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length.
A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
we know that
the equation
describe a vertical parabola with vertex at point 
if 
-------> the parabola open Up and the vertex is a minimum
if 
-------> the parabola open Down and the vertex is a maximum
in this problem we have
---> because is positive (given problem)
so
The vertex is a minimum
therefore
<u>the answer is the option C</u>
Up
