Like terms have same variable with same power. Combine like terms.
Answer:
I'm gonna go with rectangle and square
Step-by-step explanation:
rectangle: 2 pairs of parallel sides. 4 right angles (90°). Opposite sides are parallel and congruent. All angles are congruent.
Square: 4 congruent sides. 4 right angles (90°). Opposite sides are parallel. All angles are congruent.
5x - 4y = 40
x intercept is when y = 0
5x - 4*0 = 40
5x = 40
x = 40/5
x = 8 x intercept = 8
y intercept is when x = 0
5*0 - 4y = 40
-4y = 40
y = 40/-4
y = -10
y intercept = -10
x intercept = 8, <span>y intercept = -10</span>
X=2 because -2x+2 Is canceled then add 2x to 6x which is 8x then add 11 to -11 that’s canceled then add 11 to 5 which is 16 then divide 16 by 8x and x =2
The cost to mail a 2-lb package is $7.
The cost to mail a 2-lb, 1 oz package is $7+$0.30(1).
That to mail a 2-lb, 2 oz package is $7+$0.30(2) = $7.60.
Following this pattern, the general formula is f(x) = $7 + $0.30x, where x represents the number of ounces OVER 2 lb.
