Answer:
c. Both m(x) and p(x) have the same output value at x = 7.
Step-by-step explanation:
For input value x, m(x) is the output value.
m(7) is the output value of the function m(x) when x=7.
p(7) is the output value of the function p(x) when x=7.
The statement m(x) = p(x) for x=7 is a statement that the output values are the same at x=7.
Answer:
x = 9
y = 9
Step-by-step explanation:
Given :
Let :
Kenyan French roast coffee = x
Cost per x = $8
Sumatran Coffee = y
Cost per y = $10
x + y = 18 - - - - (1)
8x + 10y = 9 * 18 ;
8x + 10y = 162 - - - - (2)
From (1):
x = 18 - y
Put x = 18 - y in (2)
8(18 - y) + 10y = 162
144 - 8y + 10y = 162
2y = 162 - 144
2y = 18
y = 9
x = 18 - y
x = 18 - 9
x = 9
Notice that a can is a cylinder, which is basically two circles and one rectangle. Now, the question wants area of this rectangle.
You know the width of the rectangle (or the paper), which is 11cm. How do you find the length then?
Notice that the length of the rectangle is also the circumference of the circles. From here, use C = πd where C is circumference and d is diameter. The d is given, which is 7.5 cm. Depending on the question, π can be 3.14, 22/7 or the actual pi.
multiply π and 7.5cm and you get the circumference. Multiply this to 11cm and you get area of the rectangle.
Is their a picture for the problem
Answer:
x=3/4y-6
Step-by-step explanation:
Solve for x
-4x+3y=24
Add -3y to both sides.
-4x+3y+-3y=24+-3y
-4x=-3y=+24
Then Divide both sides by -4
-4x/-4= -3y+24/-4
x=3/4y-6
