Substitution to solve the linear system

x = 2 and y =10

Step-by-step explanation:

Substitution is done by substituting one equation into another. To begin solve one equation for a variable. Both equations are already solved for a variable.

So substitute y = 5x into y = 4x + 2. Then solve for x.

5x = 4x + 2

x = 2.

Substitute x= 2 into one of the equations to solve for y.

y = 5(2) = 10

y=10.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
