Answer:
Slope = -7/4
Step-by-step explanation:
Let's find the slope between your two points.
(0,0) ; (−4,7)
(x1,y1) = (0,0)
(x2,y2) = (−4,7)
Use the slope formula:
m = y2−y1 / x2−x1
= 7−0/−4−0
=7/−4
= −7/4
Answer:
m= −7/4

Answer:
$3.35
Step-by-step explanation:
volume of balloon in the shape of sphere= 4/3 * pi * r^3 = 4.189 cubic foot
cost of 1 cubic foot of helium = 0.8
cost of 1 * 4.189 cubic foot of helium = 0.8 * 4.189 = 3.35
Answer:
c
Step-by-step explanation:
Put the numbers in order
6,7,15,36,41,43,47,49
Q1 = (7 + 15) / 2 = 22/2 = 11 <== first quartile
Q2 = (36 + 41) / 2 = 77/2 = 38.5 <== median
Q3 = (43 + 47) / 2 = 90/2 = 45 <== third quartile
difference of largest value and median.....(49 - 38.5) = 10.5
Answer:
(4, 5 )
Step-by-step explanation:
Given the 2 equations
y = x + 1 → (1)
x + 2y = 14 → (2)
Substitute y = x + 1 into (2)
x + 2(x + 1) = 14 ← distribute and simplify left side
x + 2x + 2 = 14
3x + 2 = 14 ( subtract 2 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into (1) for corresponding value of y
y = 4 + 1 = 5
Solution is (4, 5 )
