Answer:
-2
Step-by-step explanation:
The standard equation of a line is y = mx+c
m is the slope
c is the intercept
Given
Slope = -3
Get the intercept c;
Substitute m = -3 and (1, -9) into y = mx+c
-9 = -3(1) + c
-9 = -3 + c
c = -9 + 3
c = -6
The equation becomes
y = -3x + (-6)
y = -3x-6
f(x) = -3x-6
The zero of f occurs at f(x) = 0
0 = -3x-6
3x = -6
x = -6/3
x = -2
Hence the zero of the function is -2
Answer:
<h2>
(2m-7)(m+3)</h2>
Step-by-step explanation:
hello:
2m² - m - 21
∆ =b²-4ac a=2 and b= -1 and c= -21
∆ =(-1)²-4(2)(-21)=169 = 13²
m1 = (-b+√∆)/2a = (1+13)4 = 14/4 = 7/2
m2 = (-b-√∆)/2a = (1-13)4 = -12/4 = -3
the factorization is : a(m-m1)(m-m2)
2(m-7/2)(m+3) = (2m-7)(m+3)
