You wish to accumulate $14,580 in 6 years. Payments are made at the end of every six-month period into an account earning 7.2% c
BlackZzzverrR [31]
Equation required for this question:

an • 1.072^n = 14,580

Where a = payment every half year and n = number of half years

There are 12 half years in 6 years.

Therefore n = 12, substitute this.

12a • 1.072^12 = 14,580

12a = 14,580 / 1.072^12

12a = 6,330~

a = 527.5 ~

Complete the equation of the line through (-9 -9) and (-6 0)
Katena32 [7]

Answer:

y = 3x + 18

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 9, - 9) and (x₂, y₂ ) = (- 6, 0)

m = \frac{0+9}{-6+9} = \frac{9}{3} = 3, thus

y = 3x + c ← is the partial equation of the line

To find c substitute either of the 2 points into the partial equation

Using (- 6, 0), then

0 = - 18 + c ⇒ c = 0 + 18 = 18

y = 3x + 18 ← equation of line

Please help, please help
zmey [24]
Answers:
x=22
x+4=26
6x=132

Explanation:
We learned from the question that all of the angles in a triangle add up to 180 degrees.

180=angle+angle+angle

When we plug in the values that the question gives us for the angles, we get this equation:

180=x+6x+(x+4)

After solving this equation, we get 22 as the value of x (The process of solving that equation is in the picture attached).

To solve for (x+4), we plug in the value of x, which is 22 and add 4.

(x+4)
=(22+4)
=26

And finally, to solve for 6x, we plug in 22 again:

6x
=6*22
=132

Hope this helps!
