Answer:
For a polynomial of the form ax2+bx+c a x 2 + b x + c , rewrite the middle term as a sum of two terms whose product is a⋅c=2⋅−2=−4 a ⋅ c = 2 ⋅ - 2 = - 4 and whose sum is b=−3 b = - 3 . Factor −3 - 3 out of −3x - 3 x .
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
where
k is the constant of variation
in this problem we have
the point
so
substitute
therefore
<u>the answer is</u>
Answer:
the equation in letter D is a linear function.
Answer:
The current temperature on the X scale is 1150 °X.
Step-by-step explanation:
Let is determine first the ratio of change in X linear temperature scale to change in Y linear temperature scale:
The difference between current temperature in Y linear scale with respect to freezing point is:
The change in X linear scale is:
Lastly, the current temperature on the X scale is:
The current temperature on the X scale is 1150 °X.
