Answer:
x = -27
Step-by-step explanation:
-x/3 = 9
Multiply each side by -3
x/-3 * -3 = 9*-3
x = -27
a) A line containing point F-DF
b) Another name for line k-BC
c) A plane containing point A-M
d) An example of three non- collinear points.-(B,A)
e) The intersection of plane M and line k-C
Answer:
John
Step-by-step explanation:
70 mi/(60 min) ≈ 1 1/6 mi/min.
1 1/6 miles is significantly farther than 50 ft, so John is driving (much) faster.
First you would have to convert , so 12 inches = 1 foot . So do 12 X 16= 192inches, then subtract 192-6=186inches should be the difference IN INCHES. If you need it in feet divide 186 by 12 which should give you 15.5feet
Answer:
Step-by-step explanation:
f(x) = 2x² + 14x - 4
= 2(x² + 7x) - 4
= 2(x² +7x + 3.5²) - 2(3.5²) - 4
= 2(x+3.5)² - 28.5
vertex (3.5, -28.5) = (7/2, -57/2)
The vertical intercept is the y-intercept, i.e., f(0) = -4.
The x-intercepts are the values of x for which y=0.
2x² + 14x - 4 = 0
x = [-14±√(14²-4(2)(-4))]/[2(2)] = [-7±√57]/2 ≅ -7.27, 0.27
