Camden was given a gift card for a coffee shop. Each morning, Camden uses the card to buy one cup of coffee. The amount money remaining on the card after buying x
x cups of coffee is given by the equation
A=−3.50x+ 35.
A=−3.50x+35.What is the slope of the equation and what is its interpretation in the context of the problem?

If the slope of one line equals the slope of another line then ? a) the two lines are intersecting lines b) the two lines are perpendicular lines c) the two lines are parallel lines d) the two lines always have very steep slopes

Could somebody me with this radical simplification?

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
