Hi.
To formally answer your question:
D. y = 0.75<em>x</em> + 11
We can prove this by substituting <em>x</em> with 1 (the initial measurement)
y = 0.75(1) + 11 = 11.75

Do you have a picture to go with this? I can't help without the picture :(
So you would need to add:
500$ + 80$ + 175$ = 755$
Since John paid 900$ then you would subtract how much he is buying it for from how much Davis spent to fix it
900$ - 755$ = 145$ (on profit Davis earned)
Answer: -6x^7
Step-by-step explanation:
2x^3 × (-3x^4)
=(2×-3) · (x^3 × x^4) ⇔ multiply the like terms
=-6 × [x^(3+4)] ⇔ the multiplication of exponents works as addition if same base
=-6x^7
