Answer:
Step-by-step explanation:
The vertex form of a parabola is given by y = a(x - h)^2 + k, where (h, k) is the vertex.
Given vertex at (2,-3), h = 2, k = -3
y = a(x - 2)^2 + (-3) = a(x - 2)^2 - 3
The parabola passes through (0,5) so
5 = a(0 - 2)^2 - 3
5 = 4a - 3
4a = 8
a = 2
The parabola equation in vertex form:
y = 2(x - 2)^2 - 3
Answer:
Y = 1/3x + 2
Step-by-step explanation:
Since the line increases by 1 unit then goes to right 3 units the line equation must have a slope of 1/3 and must have a y intercept of + 2 since the line crosses the Y axis at +2
Answer:
Step-by-step explanation:
Please enclose the fractional coefficient inside parentheses: y= (1/2x) − 3 for greater clarity.
Make a table of ordered pairs:
x y = (1/2)x - 3
0 -3
1 (1/2)(1) - 3 = -2 1/2
3 (1/2)(3) - 3 = -3/2
The y-intercept is the point at which x = 0, and (from the table) is -3. Plot a dark dot at (0, -3).
Now graph (3, -3/2), leaving a dark dot.
Draw a line thrugh (0, -3) and (3, -3/2).
Answer:4.5
Step-by-step explanation:
2+3+1=6, 3 divided by 6 equals to 1/2. 1/2 times 9 equals 4.5 pounds of walnuts
