Answer:
x = 6 and w = -4
Step-by-step explanation:
(-5x+2)/7 = -4
-5x+2 = -4*7
-5x+2 = -28
-5x = -28 - 2
-5x = -30
x = -30/-5
x = 6 CHECK!!
17-3(w+5) = 6(w+5)-2w
17-3w-15 = 6w+30-2w
17-15-30 = 6w-2w+3w
-28 = 7w
w = -28/7
w = -4 CHECK!!
Answer:
108 cm^2
Step-by-step explanation:
A trapezoid has an altitude of 12 cm. Its parallel sides measure 10 and 8 cm, respectively.
The base of trapezoid are 10 and 8 cm
Height of a trapezoid = 12cm
Area of a trapezoid formula = 
= 
=108cm^2
A) the x-values on the graph are [-2, 4].
all the x-values of the graph are the Domain of the function of the graph. they are found by projecting the graph to the x-axis. check the yellow line in the first picture.
b) all the possible outputs of g are [-1, 3].
all the possible outputs of g, are the Range of g. These are found by projecting the graph to the y-axis. check the red line in the second picture.
c) -1 , 0, 1, 2, and 3 are only a few values in the Range. The range is [-1, 3].
d) we will sketch a graph whose domain is [-2, 4] and range is [-1, 3]. check picture 3
Answer:
Volume = 35 cubic cm
Step-by-step explanation:
V=whl=1·2·7=14
14 +
V=whl=3·1·7=21
21 + 14 = 35
