The quadratic formula is x equals negative b plus or minus the square root of b squared minus four times a times c, all over 2a.
Looking at the equation, we can find the values for a, b, and c
a=7
b= -10
c= -2
So then putting that back into standard form, which is ax^2+bx+c, we know Haley's function in standard form is 7x^2-10x-2
Answer: A
Step-by-step explanation:
L=Length W=Width
3W=2L+2
4L=2L+2W+12
2L=2W+12

Answer:
<h2>A) y= -x + 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line<em>:</em>
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
==========================================
We have the points (-1, 2) and (4, -3).
Calculate the slope:
Put the value of the slope an the coordinates of the point 9-1, 2) to the equation of a line:
<em>subtract 1 from both sides</em>
Finally:
Answer:
75, 77
Step-by-step explanation:
Let the first odd number = 2x -1
Let the second odd number = 2x + 1
2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.
4x + 18 = 170 Subtract 18 from both sides.
4x = 170 - 18 Combine like terms on the right
4x = 152 Divide by 4
4x/4 = 152/4
x = 38
2 * 38 - 1 = 75
2 * 38 + 1 = 77
