Answer:
Width = 9 cm, length = 14 cm
Step-by-step explanation:
Width = w; Length = L
2(W+L) = 46, W+L = 23, W= 23-L
W*L = 126, (23-L)*L = 126
W = 9, L = 14
The range of a linear function can be found by evaluating the end-points, namely [-2,2] (assuming [-2,2] interval notation meaning from -2 to 2 was intended).
f(-2)=-6-12=-18
f(2)=6-12=-6
so the range of function f(x)=3x-12 for the domain [-2,2] is [-18,-6].
If the domain is actually {-2,2}, meaning only x=-2 and x=2, then the range would be {-18,-6}, i.e. exactly two points.
Answer:
B, E, D
Step-by-step explanation:
You just look for the ones that have the same factors as 5:2
Answer:
81, 000
Step-by-step explanation:
86 = 90
904 = 900
90 x 900 = 81, 000
Answer:
answer b. y = 3x + 4
Step-by-step explanation:
y = ax + b
with a and b being as follows:
a = slope, which is given as 3.
b = the y–intercept meaning, where the line intercepts the y axis, which is given as 4.
Now you know the answer of the equation of the line, which is answer b. y = 3x + 4
