Step-by-step explanation:
All if the sides and angles are the same.
Hello,
So it's asking how much per year profit if puting in 550$ every month for 40 years is and earns .06% a year so multiply 550 x 12...
12 months in a year right?
Awesome! hard part out the way. Now we should have 6,000 in that a year so now let's do the interest formula and figure it out...
6000 x .06 x 40 = 14,400$ after 40 years saving...
Congrats buddy!
Answer:
You will pay $3.50 tax
Step-by-step explanation:
$50 * 7% =
$50 *0.07 =
$3.50
Step-by-step explanation:
x=-2+y
7(-2+y)+2y=-5
-14+7y+2y=-5
9y=9
y=1
x=-2+1
x=-1
To find the point of intersection, we want to set the two equations equal to each other to find where they meet. The problem is, we have two variables, which means we can't just set them equal to each other as is. We need to manipulate the equations so that we can remove one of the variables at a time to solve for the other one.
First, let's move y to one side so we can solve for x.
2x-3y=9
2x-9=3y
y=(2x-9)/3
5x+4y=11
4y=11-5x
y=(11-5x)/4
Now that they both equal the same thing (y), we can set them equal to each other and solve for x. This will give us the x value for the point of intersection of the lines.
(11-5x)/4=(2x-9)/3
3(11-5x)=4(2x-9)
33-15x=8x-36
33+36=8x+15x
69=23x
x=69/23
x=3
Now, we can do the opposite, and solve for x to find the y coordinate.
2x-3y=9
2x=3y+9
x=(3y+9)/2
5x+4y=11
5x=11-4y
x=(11-4y)/5
(3y+9)/2=(11-4y)/5
5(3y+9)=2(11-4y)
15y+45=22-8y
15y+8y=22-45
23y= -23
y= -1
The coordinates for the point of intersection of the two lines is (3, -1).
