Answer:
D is the correct answer.
Step-by-step explanation:
Find the portion of the graph that is above the x-axis.
In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9.
Responda:
1.) 6;
2.) d) O pai tem 36 anos e o filho tem 12 anos.
Explicação passo a passo:
1.)
Dada a equação: 3x - 4 = 14
3x = 14 + 4
3x = 18
Divida os dois lados por 3
x = 6
2) Dado que ;
Idade do pai = 3 vezes a idade do filho
Idade do pai + idade do filho = 48
Deixe a idade do pai = f; idade da criança = c
Matematicamente ;
f = 3c - - - (1)
f + c = 48 - - - - (2)
Substitua f = 3c em (2)
3c + c = 48
4c = 48
c = 48/4
c = 12
Substitua c = 12 em (2)
f + 12 = 48
f = 48 - 12
f = 36
Portanto ;
Idade do pai = 36 Idade da criança = 12

Step-by-step explanation:
Answer:
Option D: is the function
Explanation:
Let the general form of quadratic equation be The function passes through the intercepts and and also passes though the point Substituting the points , and in the equation , we get, -----------(1) ----------(2) -----------(3)
Subtracting (1) and (2), we get, -----------(4)
Subtracting (2) and (3), we get, ------------(5)
Multiplying equation (4) by 5 and equation (5) by 4, to cancel the term b when adding, we get,
Thus, the value of a is Substituting in equation (4), we get,
Thus, the value of b is Now, substituting the value of a and b in equation (1), we have,
Thus, the value of c is Now, substituting the value of a,b and c in the general formula , we get,
Taking out the common term as -2 we get,
Factoring , we get,
Thus, the function is
