Answer:
y = -1x - 3
Step-by-step explanation:
y2 - y1 / x2 - x1
-1 - (-9) / -2 - 6
8/-8
= -1
y = -1x + b
-1 = -1(-2) + b
-1 = 2 + b
-3 = b
Answer:
a10 = 12/7
Step-by-step explanation:
an = a1 + (n-1) d
a10 = 3/7 + ( 10-1) 1/7
a10 = 3/7 + (9) 1/7
a10 = 3/7 + 9/7
a10 = 12/7
Answer:
The other factor is (x + 2).
Step-by-step explanation:
If x - 10 is a factor of x^2 - 8x - 20 then we must find another factor that includes +2x, so that we have -10x + 2x = -8x. That factor is (x + 2):
x^2 - 8x - 20 = (x - 10)(x + 2)
As a test, multiply -10 and +2. We get -20, matching the constant of the given polynomial. Also, -10x + 2x = -8x, another match.
Answer:
Both D and E are true statements.
Step-by-step explanation:
When you have the base form of slope-intercept form:
y = mx + b
The m (which is the coefficient of x) is the slope of the line. In this case that would be 4.
The b is the intercept. In this case it would be -6
