Answer:
26
Step-by-step explanation:
4(x-4)-3x=10
- Rule = a(b + c) = ab + ac
- Rule = a(b - c) = ab - ac
4(x-4) = 4x - 16
4(x-4)-3x=10
4x - 16 - 3x = 10
x - 16 = 10
x -16 +16 = 10 +16
x = 26
Hope this helps ^-^
B + 7.4 = 4.8
b = 4.8 - 7.5
b = -2.7
hope this helps :)

Answer: A) -0.83</h3>
Without the actual numeric data coordinates, it is impossible to compute the true r value. Though we can estimate. The data points are negatively correlated in a fairly strong manner. We can draw a straight line close to all of these points, so the r value is going to be fairly close to -1. The closer r is to -1, the stronger the negative correlation. Having r = -1 exactly means all of the points fall on some single straight line that slopes downward.
Choice B is the next best choice, but its correlation isn't as strong. So that's why I ruled it out. Choices C and D are ruled out immediately since they are positive values.
