Answer:
Step-by-step explanation:
So, our friendly number will be 300: it's only two numbers away from 298!
We multiply 300 by 6: it's 1800. (3*6=18, and the 0s we can just add at the end)
now we only need to subtract those two numbers (mupliplied by 6): so we subtract 12.
the result will be 1800-12=1788.
Answer:
c. -1
b. 5
Step-by-step explanation:
x^2 - 4x - 5 = 0
Factor
What two numbers multiply to -5 and add to -1
-5*1 = -5
-5+1 = -4
(x-5) (x+1) =0
Using the zero product property
x-5 =0 x+1 =0
x=5 x=-1
Step-by-step explanation:
when applying a mathematical basic operation, we do this to the expressions of each function.
g(x) - f(x) = (x² + 5) - (4x - 7) = x² - 4x + 12
(1/2,3)(2,3/4)
slope = (3/4 - 3) / (2 - 1/2) = (3/4 - 12/4) / (4/2 - 1/2) =
(-9/4) / (3/2) = -9/4 * 2/3 = -18/12 = -3/2
