Answer:
15
Step-by-step explanation:
The total of hot choclate made by Whitney = 7 1/2 quarts.
= 7 (2) + 1 15
----------- = ---
2 2
each mug holds 1/2 quarts
Total quarts of the hot chocolate ÷ quarts of hot choclate hold by each mug:
= 15/2 ÷ 1/2
= 15/2 x 2/1
= 15
Whitney will be able to fill 15 mugs
Answer:
y = 2x + 3
Step-by-step explanation:
Given:
(2, 7) and (0, 3)
Find the slope between the two points:
(x1, y1) = (0, 3)
(x2, y2) = (2, 7)
(y2 - y1)/(x2 - x1)
(7 - 3)/(2 - 0)
4/2 = 2
m = 2
y = mx + a
y = 2x + a
Use one of the two points to find a (I will use point (2, 7):
7 = 2(2) + a
7 = 4 + a
a = 3
Slope-intercept Form: y = 2x + 3
Point-slope Form: y - 3 = 2x
Point-slope Form: y - 7 = 2(x - 2)
General equation: 2x - y + 3 = 0
1 + 1 = 2
Correct.
Hope this helps. c:
51 x 8 = 408
It can be in this way: 51*8=408
f(x)=19x+2→ Switch the f(x) with a y
y=19x+2→ Switch the places of the x and the y variables
x=19y+2→ Solve for y
x−2=19y
y=9x−18
The inverse is f−1(x)=9x−18
