Find a and b if the points p(6,0) and q(3,2) lie on the graph of ax + by =12

s2008m [1.1K]

Answer:

$a= 2$

$b = 3$

Step-by-step explanation:

Given

$p(x,y) = (6,0)$

$q(x,y) = (3,2)$

$ax + by = 12$

Required

Find a and b

In $p(x,y) = (6,0)$ , $x = 6$ and $y = 0.$

This gives:

$a*6 + b*0 = 12$

$6a = 12$

Divide by 6

$a= 2$

In $q(x,y) = (3,2)$ . $x = 3$ and $y = 2.$

This gives:

$a*3 + b*2 = 12$

$3a + 2b = 12$

Substitute 2 for a

$3*2 + 2b = 12$

$6 + 2b = 12$

Collect Like Terms

$2b = 12 - 6$

$2b = 6$

Divide by 2

$b = 3$

Lola dice Argos mi perro tiene 10 kg menos que roco cuantos kilogramos tiene argos

Elena L [17]

Answer:

$A=R-10$

Step-by-step explanation:

The problem is:

<em>Lola says: Argos, my dog, has 10 kilograms less than Roco. How much kilograms Argos has?</em>

<em />

This problem is about algebraic language. We just need to express the ordinaty language into an equation.

We know the words less means difference. So, let's call $A$ Argos' weight and $R$ Roco's weight. We can expresse the given problem as

$A=R-10$

Notice that we applied a difference due to the word "less" in the problem.

Therefore, Argo's weight is given by the expression

$A=R-10$
