<h3>
Answer: Vertex is (2,2)</h3>
=====================================
Explanation:
The equation
y = -3x^2 + 12x - 10
is in the form
y = ax^2 + bx + c
with a = -3, b = 12, c = -10
Plug the 'a' and 'b' values into the equation below to find the x coordinate of the vertex
h = -b/(2a)
h = -12/(2*(-3))
h = -12/(-6)
h = 2
The x coordinate of the vertex is h = 2, which is then used to find the y coordinate of the vertex
y = -3x^2 + 12x - 10
y = -3(2)^2 + 12(2) - 10
y = -3(4) + 12(2) - 10
y = -12 + 24 - 10
y = 12 - 10
y = 2
The y coordinate of the vertex is k = 2
The vertex is (h,k) = (2,2)
Answer:
b=9
Step-by-step explanation:
divide by 3 on both sides to get the variable (b) by itself
René Descartes provided the first systematic link between Euclidean geometry and algebra.
<h3>What is Geometry?</h3>
This branch of mathematics involves the study of object shape, their spatial relationship and that of their surrounding space.
René Descartes is referred to as the father of analytic geometry due to him establishing the relationship between Euclidean geometry and algebra.

The valued of the expression is 1 .
So do (21/2+49/4)-3/2=You get 21 1/4 miles
Since 21 1/4 is close to 21 1/2, this answer is reasonable. So A is the answer
