i think point G desribe the point D
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
Hi!
<u>Explanation: </u><u><em>This question is about math, and this lesson is about order of operations. I will give you a hint. You had to used PEMDAS, P-Parenthesis should be go first, E-Exponents, M-Multiply, D-Divide, A-Add, and S-Subtract. If you use multiply, divide, add, or subtract it should go left to right. First, you had to multiply and divide should go left to right. And it gave us -15+10. And finally, you should add and subtract by left to right. And it gave us -5 is correct answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>
Following the example given where "square, then subtract 5" refers to squaring the variable x and then subtracting 5 from it.
f(x) = x² - 5
The "rule" we must then express in function notation is "subtract 6, then square". The rule appears to suggest that the number 6 is being subtracted from the variable x. Then the entire expression is squared, resulting in the following function:
f(x) = (x - 6)²
