Answer:
Option A) (6, 0)
Step-by-step explanation:
we have
Isolate the variable y
Divide by -2 both sides
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
The solution of the inequality is the shaded area below the solid line
we know that
If a ordered pair is a solution of the inequality, then the ordered pair must lie in the shaded area of the solution set
so
(6,0) ----> belong to the shaded area
(-6,0) ---> not belong to the shaded area
(1,6) --> not belong to the shaded area
(-1,6) --> not belong to the shaded area
therefore
(6,0) is in the solution set
Answer:
(3x - 5)(x + 1)
Step-by-step explanation:
We need to factor 3x² - 2x - 5.
In order to do this, we must look at the factors of 3 and -5:
3 = 1 * 3
-5 = 1 * -5
Somehow, we need to pair up these so that they add to -2. We realize we can do this by multiplying 1 by -5 and adding that to 1 * 3:
1 * -5 + 1 * 3 = -5 + 3 = -2
So, we have (3x - 5)(x + 1).
Answer:
175 cm
Step-by-step explanation:
to the nearest ten means we look at the ones digit
since it has to round to less than 180, we know that the number cannot be greater than 180
the number cannot be less than 170 because if it were 169 it would no be able to get to 180 by rounding to the nearest 10 since it is more than 10 away
so we have the numbers 170 - 179 to work with
using rounding, 170 - 174 would all round to 170
175 - 179 would round to 180
the least number from 175 - 179 is 175, so that is our answer
1. X = 36 2. Y= 25 3. B= 63 4. Y= 25
