Answer:

Lorena made a mistake when she subtracted x1 from x2

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

In this problem we have

=\frac{63-51}{-2-(-4)}

=\frac{12}{-2+4}

=\frac{12}{2}

=6

The points are (-4,51) and (-2,63)

therefore

Answer:

  y = 3.02x^3 -5.36x^2 +5.68x +8.66

Step-by-step explanation:

Your graphing calculator (or other regression tool) can solve this about as quickly as you can enter the numbers. If you have a number of regression formulas to work out, it is a good idea to become familiar with at least one tool for doing so.

__

If you're trying to do this by hand, the x- and y-values give you 4 equations in the 4 unknown coefficients.

  a·1^3 +b·1^2 +c·1 +d = 12

  a·3^3 +b·3^2 +c·3 +d = 59

  a·6^3 +b·6^2 +c·6 +d = 502

  a·8^3 +b·8^2 +c·8 +d = 1257

Solving this by elimination, substitution, or matrix methods is tedious, but not impossible. Calculators and web sites can help. The solutions are a = 317/105, b = -75/14, c = 1193/210, d = 303/35. Approximations to these values are shown above.

Can you please help me solve this equation? x+9−3≤14
aleksley [76]
X+9-3≤14

Add 3 to the other side. (do the inverse of subtraction)

x+9≤17

Subtract 9 on both sides. (the inverse of addition)

x≤8

I hope this helps!
