What is y=1/2x +2 y= -x +5 using subsitution

1 answer:

4 0

Y=1/2x+2
y=-x+5
subsitute since they both equal y
1/2x+2=y=-x+5
1/2x+2=-x+5
subtract 2 from both sides
1/2x=-x+3
multiply both sides by 2
x=-2x+6
add 2x to both sides
3x=6
divide both sides by 3
x=2
subsitue
y=-x=5
y=-2+5
y=3

x=2 and y=3
solution in (x,y) form is (2,3)

A rectangle has a length of 14 yards less than 9 times its width. If the area of the rectangle is 6183 square yards, find the le

Jlenok [28]

Answer:

$l=238\ yards$

Step-by-step explanation:

From the question we are told that:

Area of Rectangle A=6183

Equation of Length

$l=9w-14$

Where

$w=width\ of\ triangle$

Generally the equation for Area of Rectangle is mathematically given by

$A=(9w-14)w$

$A=9w^2-14w$

$6183=9w^2-14w$

$9w^2-14w-6183=0$

$w=28$

Therefore

$l=9(28)-14$

$l=238\ yards$
