Answer:
B.
Step-by-step explanation:
The vertices of triangle ABC have coordinates A(5,2) B(2,4) and C(2,1).
The mapping for reflection in the x-axis is
When we reflect triangle ABC in the x-axis, we obtain
A1(5,-2) B1(2,-4) and C1(2,-1).
The mapping for 90 degrees clockwise rotation about the origin is
When we rotate the resulting triangle through 90 degrees clockwise above the origin, we obtain;
A2(-2,-5) B2(-4,-2) and C2(-1,-2).
The vertices of triangle A''B''C'' also have coordinates A''(-2,-5) B''(-4,-2) and C''(-1,-2).
Hence the rule that describes the composition of transformation that maps ABC to A''B''C'' is
The correct choice is B.
Assuming these are dimensions of a rectangle, and you are interested in the perimeter and area, you can use the appropriate formulas.
P = 2(L +W)
P = 2(7 cm +7 cm) = 28 cm
A = L*W
A = (7 cm)*(7 cm) = 49 cm²
Answer:
b= -48
Step-by-step explanation:
by transposing,
43=59+b/3
b/3+59=43
b/3=43-59
b/3= -16
b= -16×3
b= -48
therefore the answer is b= -48

Answer:
P: $0.12/kWh; M: $0.15/kWh
$285 from company P
Step-by-step explanation:
The cost per kWh from Company P is found by dividing the cost by the corresponding number of kWh:
$150/(1250 kWh) = $0.12/kWh
The cost per kWh from Company M is the coefficient of x in the equation:
$0.15/kWh
__
Company P provides power for a lower cost. The cost from Company P for 2375 kWh is ...
(2375 kWh)×($0.12/kWh) = $285 . . . cost for 2375 kWh
