Answer:
3x - 2y = -1
Just so you know, this equation is of a line on a graph. It is in standard form.
Ax+By=C, A and B cannot equal zero and A is greater than zero.
A=3
B=-2
C=-1
As need coordinates for x and y.
Let's make this easy, and begin with x=0
[(3)(0)]-[2y]=-1
-2y=-1
Let's divide both sides by -2 to isolate y...
(-2y)/-2=-1/-2
y=1/2
(0,1/2)
y=0
3x - 2y = -1
[3x]-[(2)(0)]=-1
3x=-1
(3x)/3=-1/3
x=-1/3
(-1/3,0)
For the third, how about x=1...
3x - 2y = -1
[(3)(1)]-2y=-1
3-2y=-1
Let's subtract 3 from both sides...
-3+3-2y=-1-3
-2y=-4
y=2
(1,2)
Step-by-step explanation:
45 grams is about 1/4 cup of water or maybe 1/4 cup of flour or uncooked rice would be 45 grams. Anyway it's not much.
Unless the dresser is made of paper, 45 grams is not enough. 45 kg though large (that's roughly 100 pounds if that's what you think in), the dresser might be found in the apartment where Sherlock Holmes lives. (The dresser is a piece of victorian furniture) it is much closer to what a modern dresser would weigh.
<span>The maximum amount that Connie can pay for a new CD is $15, so we will keep this on one side of our equation. Next, we equate this to the sum of the CD's price and the tax. Let x represent the price of the CD. The sales tax applied will be 0.05x. Therefore, we get the equation
15 = x + 0.05x.
Solving:
15 = 1.05x
x = $14.29
The first option is correct.</span>
