Answer:
Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
Answer:
45.5 ft^2
Step-by-step explanation:
The area of the garden is (7 ft) by (13 ft), which works out to 91 ft^2.
The half garden used for cucumbers is (91 ft^2)/2, or 45.5 ft^2.
Answer:
The center of dilation of ABCD to EFGH is (0, 0), and the scale factor is 4/3
Answer:
x=4
Step-by-step explanation:
19+3x=3(x-5)
do rainbows
19+3x=3x-15
subtract 19 on other side
3x=3x+4
divide out the 3s
x=4
