Step-by-step explanation:
Exercícios:
9. Sobre o estudo de equações, escreva V para as afirmações verdadeiras e F para as falsas.
a) ( ) A expressão 17 - 4x + 25 representa uma equação.
b) ( ) O número 23 representa um dos membros da equação -9x + 4 = 23.
c) ( ) Na equação x + 4 = 3x + 20, a incógnita é x.
d) ( ) A equação 3y - 15 = 0 não tem segundo membro.
<span>P(At least one sum of 8) = 1 - P(No sums of 8)
P(At least one sum of 8) = 1 - (1 - 5/36)^2
P(At least one sum of 8) = 1 - (31/36)^2
P(At least one sum of 8) = 1 - 961/1296
P(At least one sum of 8) = 335/1296
So the answer is choice B

This means an initial fee of $45 have to be paid to the provider and a charge of $35 per month.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the initial value of y.
Let S represent the total cost of service for x months. Given:
y = 35x + 45
This means an initial fee of $45 have to be paid to the provider and a charge of $35 per month.
