X = 4

Porque:

5(x + 3) = 2x + 3

5x + 15 = 2x + 3

5x - 2x = 3 - 15

- 3x = - 12

x = -12/ -3

x = 4 ✔️

DerKrebs [107]

Answer: C. an investment plan that guarantees payments at regular intervals after retirement


Step-by-step explanation:

  • The definition of an annuity is a sum of money or an investment that is paid at regular intervals after retirement.

Annuities are formed and sold by financial institutions, which accept and invest funds from persons and then, upon annuitization, issue a sequence of payments at a later point in time (mostly after retirement).

What is an equation of the line that passes through the points of (0,-4) and (-4,6)
dusya [7]

Answer:

y = -5/2x - 4

Step-by-step explanation:

(0,-4) and (-4,6)

Slope:

m=(y2-y1)/(x2-x1)

m=(6+4)/(-4-0)

m=10/-4

m= -5/2

Slope-intercept:

y - y1 = m(x - x1)

y + 4 = -5/2(x - 0)

y + 4 = -5/2x

y = -5/2x - 4

Find the equation of the line that is perpendicular to y = –3x + 1 and passes though the point (6, 3).
JulsSmile [24]

Answer:

y = \frac{1}{3} x + 1

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 )

y = - 3x + 1 ← is in slope- intercept form

with slope m = - 3

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-3} = \frac{1}{3}, thus

y = \frac{1}{3} x + c ← is the partial equation of the perpendicular line

To find c substitute (6, 3) into the partial equation

3 = 2 + c ⇒ c = 3 - 2 = 1

y = \frac{1}{3} x + 1 ← equation of perpendicular line
