Answer: y = -6x + 5
Step-by-step explanation:
equastion is y = dx + e
+) Because it perpendicular y = \dfrac{1}{6} x + 3
d \times \dfrac{1}{6} = -1
<=> d = -1 : \dfrac{1}{6}
<=> d = -6
=> y = -6x + e;
+) Because it contains the point (-3; 23)
=> 23 = -6 \times (-3) + e
<=> e = 5
=> y = -6x + 5
For this case we must compare the unit costs of the options given and determine which is the best option.
Option 1:
Six yards of rope costs $5.50
Option 2:
Four yards costs $ 4.75
Thus, the best option is the first. It is the lowest unit cost.
Answer:
The best option is the first. It is the lowest unit cost.
Answer:
-5
Step-by-step explanation:
7−2−10
=5−10
=-5
-x2 - 2
If you learned to do it in a specific order then it’d look more like -1(x2+2)
