Answer:
x is less than 16/9 x is greater than or equal to -19/13
Answer:
A=1.5 units²
Step-by-step explanation:
a²+b²=c²
2.5²+1.5²=c²
a²+2.25=6.25
a²=4.00
a=2
A=1/2 x b x h
A=1/2 x 1.5 x 2
A=1.5 units²
This is basically asking if each transformation is an isometry, which maps a triangle to a congruent triangle.
(x,y)⇒(-y,x) That's an isometry, not scaling x or y. I think it's a 90 degree rotation. CONGRUENT
(x,y)⇒(x-2,y-1/2) No scaling, pure translation. CONGRUENT
(x,y)⇒(2x,2y) That's a double scaling so NOT CONGRUENT
(x,y)⇒(-x,y) That's a reflection. CONGRUENT
(x,y)⇒(1/2 x, 1/2 y) Scaling again, NOT CONGRUENT
Answer:
Linear relationships can be expressed either in a graphical format where the variable and the constant are connected via a straight line or in a mathematical format where the independent variable is multiplied by the slope coefficient, added by a constant, which determines the dependent variable
Answer:
5x+6y
Step-by-step explanation:
just add like terms
