Answer:
marcus
Lilian
Pamela
Step-by-step explanation:
simplefy the expresion wich will equal 58
Answer:
1) Marcus 2) Lillian 3) Pablo
Step-by-step explanation:
For these type of expressions you have to use "PEMDAS"
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
(IT ALWAYS HAS TO GO FROM LEFT TO RIGHT)
1) Marcus Why Marcus?
Because, Melanie added instead of dividing first.
Melanie: Marcus:
8 x 7 + 14 / 7 8 x 7 + 14 / 7
56 + 14 / 7 56 + 14 / 7
70 / 7 56 + 2 <---
10 58
2) Lillian Why Lillian?
Because, Landon Multiplied instead of dividing.
Lillian: Landon:
50 / ([tex]5^{2}[/tex] - 15) x 5 50 / ([tex]5^{2}[/tex] - 15) x 5
50 / (10) - 5 50 / (10) - 5
5 x 5 50 / 50 <---
25 1
3) Pablo Why Pablo?
Because, Pamela didn't follow the L --> R- (Left to Right) -Rule.
Pablo: Pamela:
(12 + [tex]2^{2}[/tex]) / 4 x 5 (12 + [tex]2^{2}[/tex]) / 4 x 5
([tex]14^{2}[/tex]) / 4 x 5 (12 + 4) / 4 x 5 <---
196 / 4 x 5 16 / 4 x 5
49 x 5 4 x 5

Introduce points (x,y) (0,2) i.e one of the given points ,it should give same answer either way
(0,2)(x,y)
y-2/x-0=5/2
Cross multiplication,2(y-2)=5(x-0)
2y-4=5x-0
2y=5x-0+4
2y=5x +4
Divide both sides by 2 to get
y=5/2x+2.

which of the following is true about the function below? 1/√x-6
Answer:
Assuming the x-6 is under the square root sign, the value must be greater than 6 because you can not have 0 in the domain. That narrows it down to either B or C but since the denominator can not be anything less than 0, your answers will always be positive so that means the answer is Its domain is (6,∞)
Answer:
Its domain is (6,∞) and its range is (0,∞) your welcome :3
