Answer:
minimum temp: 278 degrees. Maximum temp: 292 degrees
Step-by-step explanation:
First, what goes in the absolute value? It is the difference between 285 and the actual temperature, because this needs to be no larger than 7. Your starting equation will look like this.
You then have to split this into 2 different equations.
and 
The reason the second one is flipped an negative is because for it to be no more than 7 degrees below, the difference will need to be closer to zero, which means greater than -7.
Now you simply solve your 2 separate equations.
Starting with the first one:
And the second equation:
Answer:
Step-by-step explanation:
In any triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse, or longest side, of the triangle (o/h).
Therefore, we have:
The equation of a line is y = mx + b
We know there is a b because the y intercept is not zero, so the first choice is wrong. We also know the last choice is wrong because this problem definitely has a slope (m).
The slope of the line of best fit seems to be closest to 3.25, meaning it goes up about that much for every one unit it goes to the right.
The second choice is correct.
Isolate the X in the second equation
x=2y+14
Substitute that in for the x in the fist equation
7(2y+14) + 2y = 2
Distribute the 7
14y+14+2y=2
Combine like terms
16y+14=2
Isolate the 16y
16y=-12
Isolate y by dividing the whole equation by 16
y=-12/16
Simplify
y=-3/4
That is your y. To find x, plug y into one of the equations. I'm plugging it into the version of the second equation after we isolated x.
x=2(-3/4)+14
Distribute the 2
x=(-1.5)+14
Simplify
x=12.5
