The slope: m = -1/4
3 = -1/4 · 2 + b
3 = -2 + b
b = 5
Answer:
y = -1/4 x + 5
E1.
a) So it says you need an equation for the amount spent and the amount collected. She spends money when she "used $6 worth of yarn for each scarf" and when she "paid $50 to rent a table."
The expression for the yarn is 60x (x representing the yarn per scarf).
And the expression for how much she spent with the table is simply 50, since it's a one-time thing.
So how much she spent in total is 60x + 50.
She collected money when "she sold every scarf for $10".
The expression would be 10x.
The system of equations would be:
y = 60x + 50
y = 10x
Step-by-step explanation:
when having an exponent of an exponent, the exponents are simply multiplied.
so, here we have 3/4 × 2/3 = (3×2)/(4×3) = 6/12 = 1/2
so, simplified, we have 5^(1/2).
now, a fraction as exponent indicates a root to be taken. which root is identified by the denominator of the fraction.
here this is 2 (of 1/2). so we need to take the square root.
therefore
is the right answer.

A thermally insulated vessel contains
150 g of water at 0°C. Then the air from the
vessel is pumped out adiabatically. A
fraction of water turns into ice and the rest
evaporates at 0°C itself. The mass of
evaporated water will be closest to:
(Latent heat of vaporization of
water = 2.10 x 106 Jkg - and Latent heat of
Fusion of water = 3.36 x 105J kg-1)
