0.68
Step-by-step explanation:
Answer:
Please check the explanatio.
Step-by-step explanation:
Solving Part b)
We know that the slope-intercept form of the equation line is

where m is the slope and b is the y-intercept
Given the equation

Re-writing the equation in the slope-intercept form


Here, m=-2 and b=8
Thus, the equation in the slope-intercept form will be:

Solving Part c)
As you sold two pounds of cheddar cheese.
i.e. y=2
substituting y=2 in the slope-intercept form of the line equation


Subtract 8 from both sides


Divide both sides by -2


You sold 3 pounds of swiss cheese.
Solving Part d)

putting x=2.5 in the equation



The sides are not equal
<em>FALSE</em>
Thus, x=2.5 does not make any sense in the context of the problem.
Answer:
Yi Xing invented the astronomical clock and introduced some new methods of interpolation in mathematics.
Step-by-step explanation:
Yi Xing was both an astronomer and a mathematician during the era. He invented the astronomical clock which was more accurate than the initial water and Sun's clock in use.
Furthermore, Yi Xing also discovered some new methods of interpolation in mathematics of which the meaning and interpretation became controversial. Interpolation is a method majorly in mathematics that can be used to estimate a value of a function from its discrete values. It involves first order differences and second order differences.
Also, Yi Xing was able to design a calendar in A.D. 727.

Answer:
B.12 ounces
Step-by-step explanation:
step 1
Find out the ounces of orange juice concentrate used yesterday
Let
x ----> ounces of orange juice concentrate used yesterday
y ---> ounces of water used yesterday
we know
that
----> equation A
----> equation B
substitute equation B in equation A
solve for x
step 2
today she wants to make twice as much orange juice.
To find out how much orange juice concentrate she needs, multiply the ounces of orange juice concentrate used yesterday by 2
so
