-5+17=12 - this is the quickest way to solve an easy equation like this
Answer:
Step-by-step explanation:
2x+5=-12
2x=-17
x=-8.5
Using your approximate y-intercept on the line of best fit, your equation would be y=11/7x + 3.
We find the slope by choosing two points that are on the line:
(9, 18) is easy to spot; and (2, 7) is fairly easy to spot as well. The formula for slope is:
m=y₂-y₁/x₂-x₁
m=7-18/2-9 = -11/-7 = 11/7
Slope intercept form, y=mx+b, has the slope and the y-intercept. Plugging those in we have y=11/7x+3.
-2x * 3x * -x
-6x² * -x
6x³
One way to describe the U.S. dollar if the foreign exchange rate between the U.S dollar and British pound changed from 1:1 to 1:07 is the dollar has weakened. The correct answer is C.
