Answer:
y = 70x
y = 5z + 10x
Step-by-step explanation:
First equation: y = 70x x is the number of months
Second equation: y = 5z + 10x x is the number of months
z is the number of visits
26-4=22 22 divided by 2=11
(26-4)÷2=S
(22)÷2=11
S=11
I have attached a picture of the dot plot that you described. Each dot on the number line represents one answer. So, the number of dots above the number 4 tells us that there were 6 students who have 4 email accounts.
The answer is that <span>
There are exactly 6 students with 4 email accounts.</span>
Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
