Answer:
y=-3-3x
Step-by-step explanation:
Transpose the equation for y
y=-12/4-12x/4
y=-3-3x
You can rule out A and C 6/6 makes 1 so that cancels so your answer is D
If you would like to solve (n^3 - n^4) - (3n^3 - 7n^4), you can do this using the following steps:
(n^3 - n^4) - (3n^3 - 7n^4) = <span>n^3 - n^4 - 3n^3 + 7n^4 = n^3 - 3n^3 - n^4 + 7n^4 = -2n^3 + 6n^4
</span>
The correct result would be <span>-2n^3 + 6n^4.</span>
Answer:
let x = the number of nickels
the number of pennies can be represented by (56 - x)
.05x + .01(56 - x) = 1.52
5x + (56 - x) = 152 if in the above line we multiply both sides of the equation by 100
4x + 56 = 152
4x = 96
x = 24
There are 24 nickels and 56 - 24 = 32 pennies
24 nickels are worth 24 * 5 = $1.20 and 32 pennies are obviously worth 32 cents, so the total is 1.20 + 0.32 = $1.52

Answer:
3
Step-by-step explanation:
Alright so here's the deal. Fractions are basically a way to represent a part of a whole item (or number). The number on the bottom (denominator) is the number of pieces that the item is broken into and the number on top (numerator) is how many of those pieces you have you have. For example. If you take a cup and pour it evenly into 3 glasses, you will have broken it into 3 parts. Each glass now contains 1 out of the 3 total parts.
