Do the ratios 10:20 and 2:24 form a proportion?
expeople1 [14]

We have:

10:20=\frac{10/10}{20/10}=\frac{1}{2}  \\2:24=\frac{2/2}{24/2} =\frac{1}{12} \\=>\frac{1}{2}\neq  \frac{1}{12}\\

So:    10:20\neq 2:24

ANSWER: No

Ok done. Thank to me :>

F(x)=9x-2 is it linear, exponental, or quadratic
aksik [14]

Answer: Linear

Step-by-step explanation:

Linear means that in an equation, the highest power of x is 1. Or, there are no x^2, x^3, etc. Only x^1. Quadratic means that the highest power of x is 2. This is also called the degree. The degree is the highest power of x.

1 - Qual a solução da equação 3x – 4 = 14? * 1 ponto a) 10 b) 7 c) 6 d) 15 2 - A idade de um pai é igual ao triplo da idade do f
topjm [15]

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
