Answer:

La madre de Jaime tiene 30 años más que él.

Step-by-step explanation:

Llamemos x a la edad actual de Jaime, si la edad actual de Ana es el triple que la de Jaime, entonces la edad actual de Ana es 3x.

Dentro de 15 años, la edad de Jaime será x+15 (edad actual más 15 años) y usando el mismo razonamiento, la edad de Ana será 3x + 15.

Por otro lado el problema nos dice que dentro de 15 años, la edad de Ana (que ya sabemos que será 3x + 15) será igual al doble de la que tendrá su hijo en 15 años. Esto en forma de ecuación se representa:

3x+15=2(x+15) (la edad de Ana será igual que el doble de la de su hijo)

Resolviendo la ecuación:

3x+15= 2(x+15)\\3x+15=2x+30\\3x-2x=30-15\\x=15

Por lo tanto, Jaime tiene 15 años y su madre tiene 3x=3(15)=45 años. Por lo tanto la diferencia de edad es de 30 años y Ana tiene 30 años más que su Jaime.

Step-by-step explanation:

First, find the <em>rate</em> <em>of change</em><em> </em>[<em>slope</em>], <em>m</em><em> </em><em>=</em><em> </em><em>-</em><em>y</em><em>₁</em><em> </em><em>+</em><em> </em><em>y</em><em>₂</em><em>\</em><em>-</em><em>x</em><em>₁</em><em> </em><em>+</em><em> </em><em>x</em><em>₂</em><em>.</em><em> </em>Next, you do either\or:

12 = 2(4) + b; 4 = b

8 = 2(2) + b; 4 = b

No matter which ordered pair you use, you will ALWAYS get the same answer, IF you put them in their correct places.

Consider the function below. Find f(x) = 7<br><br> f(x) = 4x - 9
Novosadov [1.4K]

Answer:

x=4

Step-by-step explanation:

it tel you that f(x) = 7 so replace "f(x)" for 7 in the equation. You then get 7 = 4x - 9 so now you solve for x. You have to isolate x so you add 9 to the other side since you do the opposite of -9. Once you add 9 and 7, then divide the answer by 4. You should get 4 = x.

Work:

f(x) = 4x - 9

7 = 4x - 9

7 + 9 = 4x

16 = 4x

16 ÷ 4 = x

4 = x
