Answer:
8
Step-by-step explanation:
The term 8x is a product (as is any term). It is the product of a constant coefficient (8) and a variable (x). The "coefficient" is the multiplier of the variable of interest, so is 8 in this term.
_____
The word "coefficient" is often used to refer to the constant multiplier in any term. For example, in the term 6xy, if we just ask for the coefficient, we are interested in the value 6.
On the other hand, if we ask for the coefficient of y in that term, we expect to be told it is <em>6x</em>. That is, the "coefficient" is the multiplier of the specified variable or constellation of variables.
Step-by-step explanation:
98 = 188t - 16t^2
-16t^2 + 188t = 98
-16t^2 + 188t - 98 = 0
8t^2 - 94t + 49 = 0
Use the quadratic formula with a = 8 , b = -94 , c = 49 to get the solutions
t = [(47 - root 1817) / 8]≈ 0.55
and
t = [(47 + root 1817) / 8] ≈ 11.20
3x - 2y = 18
Wherever the line crosses the
x-axis, y=0. 3x = 18
x = 6
The x-intercept is (6, 0) .
3x - 2y = 18
Wherever the line crosses the
y-axis, x=0. - 2y = 18
y = -9
The y-intercept is (0, -9) .
Answer:
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch
(0.167) shirts.
Step-by-step explanation:
Mike can stitch 7 shirts in 42 hours
to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.
He can stitch 1 shirt in =
= 6 hours
Now we calculate the work done in one hour.
He can stitch in 1 hour =
shirts or 0.167 shirts
Mike can stitch one shirt in 6 hours and in 1 hour he can stitch
shirts.
