what is the point and slope of the line represented by the equation below?
y + 3 = -2(x - 8)

a. slope = -2; point = (8, -3)
b. slope = -2; point = (3, -8)
c. slope = -2; point = (-8, 3)
d. slope = 2; point = (-3, 8)

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Which expression is equivalent to -5(3x - 6/7)
