Answer: 7 multiple choice questions and 8 free response questions
Step-by-step explanation: m is the number of multiple choice questions and f is the number of free response questions.
m+f=15
m+2f=23
You can subtract the first equation from the second, and get f=8
m+8=15
m=7
Answer: they are they same
Step-by-step explanation:
(7x-10) - (-6x-8)
distribute the negative to the (-6x-8)
(7x-10) + 6x+8
disregard the parenthesis because addition is associative
7x-10 + 6x+8
combine like terms
13x-2
13x-2 is the answer
Domain: possible x values
Range: possible y values
Solution: domain: all real numbers
Range: y greater than 0
The equation which represents the given graph g(x) is 2ˣ-1.
<h3>
What is Equation?</h3>
Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.
Here, given graph passes through origin.
Put x = 0 in all the given equation and verify which equations gives result as zero.
Put x = 0 in option A
g(0) = 2⁰⁺¹ = 2 ≠ 0
in option B
g(0) = 2⁰-1 = 1 - 1 = 0
Thus, option B g(x) = 2ˣ-1 is the correct expression for the given graph.
