Answer:
y = -3x + 2
Step-by-step explanation:
To find the slope of an equation you can do (y2-y1)/(x2-x1). Plug the values in from the equation and you get (-1+7)/(1-3), or 6/-2. This means the slope is -3. Then you plug the values of y and x into an equation y = -3x + b, and you get -1 = (-3)1 + b. Solve for b. -1 = -3 + b, (add 3 to each side) 2 = b. Then plug b back into your equation and you get y = -3x + 2
Answer:
73 degrees.
Step-by-step explanation:
So, let's see the information provided in the question.
At 8 AM, the thermometer was reading -5 degrees.
At 12:30 PM, the temperature has increased by 11 degrees, so it's now +6 degrees outside.
Inside Susan's house, the temperature is 7 degrees more than 11 times the outside temperature, at 12:30 PM.
So, we know the outside temperature at 12:30 PM is +6 degrees.
11 times 6 = 66 degrees.
Then we add the additional 7 degrees, to get a total of 73 degrees.
Area is length x width, and perimeter is adding up all the sides together
so if it’s 32 for the perimeter, then the dimensions should be 12 and 4
12x4 is 48
12+12+4+4 is 32
Area of a circle for (360degrees) = pi*(r^2)
Area of part of a circle with angle θ=(θ/360)*(pi*)*(r^2)
<span>(θ/360)*pi*(6^2)=12*pi
</span>solving, <span>θ=(12/36)*360
</span><span>θ=120 degress
</span>
Im probably wrong but i think you would do -4 - 7 + 3 = -8
