The question is the photo

For this question you can say:
5/9( °F - 32) = -10 °C
so now you should solve the equation:
5F/9 - 160/9 = -10 
⇒ 5F/9 = -10 + 160/9 ⇒ 5F/9 = -90/9 + 160/9 ⇒ 5F/9 = 70/9 ⇒ now you can multiply both sides of the equation by 9 so you will have:
5F = 70 ⇒ F = 14 ° F :)))
i hope this is helpful

Can anyone help me please and explain this: Write "60 pounds for $6.60" as a unit rate per ounce to the nearest tenth. 1 pound=
Pepsi [2]
<span>1 pound = 16 ounces
so 60 pounds = 60 x 16 = 960 ounces.
$6.60/960 =0.006875 per ounce.
0.006875 x 16 ounces = 0.11 (11 cents per pound)

<span>3 pounds x 0.11= 33 cents 

answer is B</span></span>

The graph shows f(x) = 1/2 and its translation, g(x).
AnnyKZ [126]
As you can see, each point on f(x) is moved up 4 units to get to g(x), so the function is g(x) = f(x) + 4.  The f(x) function cannot possibly be f(x)=1/2, though, because that would be a horizontal line through y = 1/2 and that function is clearly not a horizontal line.  So whatever f(x) is REALLY, add 4 to the tail end of it to show its translation.
