Answer:
a) y = .70x + 20
-To find this, use the rate as x since it will change based on the number of miles. Since 20 is a flat fee, it can be added at the end as a constant.
b) This graph forms a straight line.
-This is because the answer in a is a linear equation.
c) The slope is .70 and the y-intercept is 20.
-For this one, the y-intercept is always the constant at the end of the equation and the slope is the coefficient of x.
Answer:
b
a=1
Step-by-step explanation:
The answer is C: Lincoln uses 25 cents worth of supplies per cup.
1 = 1/4(2x+8)
1 = 1/2x + 2
1 - 2 = 1/2x
(-1) = 1/2x
x = (-1) : 1/2 = (-1) × 2/1 = (-2)
Answer : x = (-2)
<span>So we wan't to know hot to convert degrees Fahrenheit to degrees Celsius. Let's transform first from Celsius to Fahrenheit: 0 degrees Celsius is 32 degrees Fahrenhiet and 1.8 degrees Celsius is 1 degree Fahrenheit so: T(F)=1.8T(C) + 32. To transform from Celsius to Fahrenheit we need to invert the former equation: 1.8T(C)= T(F)-32. Now we divide the whole equation with 1.8 and we get: T(C)=(T(F) - 32)/1.8 and input our T(F)=41 F and we get: T(C) =(41-32)/1.8 and that is equal to: T(C)= 5 C. So the correct answer is B. 5 degrees C</span>
