Answer:
y-3 = 4/7(x-7)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1)
We know the slope (4/7)
and a point (7,3)
Lets substitute into the equation
y-3 = 4/7(x-7)
Answer:
Algebraic expression representing number of coffee B = 100-x
Step-by-step explanation:
An algebraic expression is an expression that contains unknowns denoted with alphabets or symbols and natural numbers.
Coffee blend is 100 pounds and x represent number of pounds of coffee A
Hence coffee B = 100-x
Algebraic expression representing number of coffee B = 100-x
Answer:
$29.25

39 - 9.75 = 29.25
<span>erry starts rowing at 2 pm from the west end of the lake, and Tao starts rowing from the east end of the lake at 2:05 pm.
------
Terry DATA:
rate = 60 meter/min ; time = x min ; distance = r*t = 60x meters
-----
Tao DATA:
rate = 40 meter/min ; time = x-5 min ; distance = r*t = 40(x-5) meters
--------------------------
If they always row directly towards each other at what time will the two meet?
------
Equation:
dist + dist = 2000 meters
60x + 40(x-5) = 2000
20x = 1800
x = 90 minutes
