Answer:

499.20

Step-by-step explanation:

3000

x.08. Interest rate

= 240 interest after one year

+. 3000

=3,240 principal plus interest after one year

x. .08

259.20. Interest in year two

+ 240.00 interest in year one

= 499.20. Interest earned in 2 years

The midpoint M of CD has coordinates (6, 6). Point D has coordinates (10, 4). Find the coordinates of point C.

Firdavs [7]

Answer:

(2,8)

Step-by-step explanation:

The midpoint of a line segment with endpoints (a,b) and (c,d) is

((a+c)/2 , (b+d)/2) .

So one endpoint is given and the midpoint is given, we are asked to find the other midpoint.

(10+c)/2=6 (4+d)/2=6

10+c=12 4+d=12

c=2 d=8

(2,8) is the other endpoint

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

$\spadesuit\; Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}$

Given Points are (8 , 30) and (18 , 60)

here x₁ = 8 and x₂ = 18 and y₁ = 30 and y₂ = 60

$\spadesuit\; Slope(m) = \frac{30 - 60}{8 - 18} = \frac{-30}{-10} = 3$

We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)

Here the line passes through the point (8 , 30)

⇒ x₀ = 8 and y₀ = 30

We found Slope(m) = 3

Substituting all the values in the standard form, We get :

Equation of the line : y - 30 = 3(x - 8)

Let d be the x-intercept of this line

⇒ The line passes through the point (d , 0) as at x-intercept, y-coordinate is zero.

⇒ 0 - 30 = 3(d - 8)

⇒ 3d - 24 = -30

⇒ 3d = -30 + 24

⇒ 3d = -6

⇒ d = -2

⇒ The x - coordinate of the x-intercept of the line is -2

-3x+4y=7 y=3x-5 I NEED HELP PL Z HELP ME

$- 3x + 4y = 7 \\ y = 3x - 5$

[Substitute the given value of y into the first equation]

$- 3x + 4 \times (3x - 5) = 7$

[Distribute 4 through the parentheses]

$- 3x + 12x - 20 = 7$

[Collect like terms]

$9x - 20 = 7$

[Move the constant to the right-hand side and change its sign]

$9x = 7 + 20$

[Add the numbers]

$9x = 27$

[Divide both sides of the equation by 9]

$x = 3$

[Substitute the given value of x into the second equation]

$y = 3 \times 3 - 5$

[Multiply the numbers]

$y = 9 - 5$

[Subtract the numbers]

$y = 4$

[The possible solution of the system is the ordered pair (x,y)]

$(x,y)=(3,4)$
