Answer:
± 3
Step-by-step explanation:
h(x) = sqrt( 2x+1)
h(4) = sqrt(2*4+1)
= sqrt(8+1)
= sqrt(9)
± 3
Answer:
11.5
Step-by-step explanation:
We solve using :
Pythagoras Theorem
LM² = MN² + NL²
NL² = LM² - MN²
NL = √LM² - MN²
NL = √14² - 8²
NL = √(132)
NL = 11.489125293
NL = 11.5
Therefore, the length of NL = 11.5
Answer:
- 43
Step-by-step explanation:
Expression: (3m+2n−6) and (−4−6m+7n)
n= -2 and m=5
Before inserting the values, let's add both expressions.
(3m+2n−6) + (−4−6m+7n)
3m+2n−6 −4 − 6m + 7n
-3m + 9n - 10
Inserting the values;
-3(5) + 9(-2) - 10
-15 - 18 -10
- 43
Answer:
B
Step-by-step explanation:
The wording in the problem statement is ...
... "less than 3 years"
... "at least 3. but less than 6 years"
so we expect the inequality symbols to look like ...
... 0 ≤ x < 3
... 3 ≤ x < 6
These match <em>the second piecewise function</em>.
The sum of 3/5 and 1/10 is 7/10.
