Question 1 (1 point)
solve the system of equations by elimination.
x+y=4
y = 2x + 6

x=-2/3, y=14/3. (-2/3, 14/3).

Step-by-step explanation:

x+y=4

y=2x+6

x+2x+6=4

3x+6=4

3x=4-6

3x=-2

x=-2/3

-2/3+y=4

y=4-(-2/3)

y=4+2/3

y=12/3+2/3

y=14/3

answer: 4

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
