Answer:

-10y+11.4

Step-by-step explanation:

you combine -2y with -8y to get negative -10y. Then you combine 3 and 8.4 to get 11. Variables usually come first in equations, I don't think it matters, but you might want to put them first anyway.

A deli sells a sandwich spread for 6.4per pound. How much do you need to pay for 24 ounces of spread?
Dafna1 [17]

Answer:

You have to pay 9.6.

Step-by-step explanation:

In order to find the answer, first you have to consider that 1 pound is equal to 16 ounces and with that information, you can use a rule of three to find the pounds that 24 ounces represent:

1 pound → 16 ounces

    x       ← 24 ounces

=(24*1)/16=1.5

Now that you know, that 24 ounces are equal to 1.5 pounds you can multiply the price per pound for the number of pounds to find the amount that you need to pay:

6.4*1.5=9.6

According to this, the answer is that you have to pay 9.6.

The scatter plot below shows the relationship between the diameter (x), in mm, and mass f(x), in grams, of a berry: ordered pair
kkurt [141]
The function would be f (x) = 0.4x - 4.

Explanation
We can see that this is linear, since it increases at a constant rate.  We find the slope using the formula
m=(y₂-y₁)/(x₂-x₁) = (0.8-0.4)/(12-11) = 0.4/1 = 0.4

We use point-slope form to write the initial equation:

y-y₁ = m(x-x₁)
y-0.4 = 0.4(x-11)

Using the distributive property:
y-0.4 = 0.4*x - 0.4*11
y-0.4 = 0.4x-4.4

Add 0.4 to both sides:
y-0.4+0.4 = 0.4x-4.4+0.4
y=0.4x-4
