Answer:
ur right
it's -1013
bc you need to do multiplication first so the equation turns out to be
10 - 1000 - 23
so then that turns to -1013 if you calculate left to right
What did ur friend get???
Answer:
2/7x + 8/7
Step-by-step explanation:
f(x) = -4 + 7/2x
y = -4+7/2x
Exchange x and y
x = -4 +7/2y
Solve for y
Add 4 to each side
x+4 = -4+4 +7/2y
x+4 = 7/2y
Multiply each side by 2/7
2/7(x+4) = 2/7 * 7/2y
2/7(x+4) = y
2/7x + 8/7
Answer:
1
Step-by-step explanation:
If we have 2 points we can find the slope
(0,-7) and (6,-1) are two points on the line
Slope is given by
m=(y2-y1)/(x2-x1)
=(-1--7)/(6-0)
= (-1+7)/(6-0)
=6/6
=1
Answer:
The correct answer is A.
Step-by-step explanation:
Given that a weather researcher compared Dublin, Ireland to Madrid, Spain, and she found that Dublin had a mean average temperature of 56.1ºF with a mean average deviation of 6.4ºF, while Madrid had a mean average temperature of 68ºF with a mean average deviation of 12.1ºF, the following conclusions can be drawn:
68 is higher than 56.1, so clearly Madrid has a higher average temperature than Dublin.
In turn, 12.1 is greater than 6.4, with which Madrid has a greater temperature variation than Dublin.
