How many solutions exist for the given equation?

Mathematics

1 answer:

grin007 [14]3 years ago

3 0

Answer:

One

Step-by-step explanation:

(x + 12) = 4x - 1

x + 12 = 4x - 1

12 = 3x - 1

13 = 3x

x = 13/3 = 4.3333333...

Since x only has one value, only one solution exists for the equation.

First we need to find what is 20% off $23,999
1) = 20/100 x 23,999= $4,799
To find the decrease over 6 years :
2)= $4,799 x 6 = $28,798.8

Finally
= 28,798.8-23,999= $4,799.8

$4,799.8 is the final value.

Which coordinate point represents the y -intercept of the equation 3x + 2y = 18

scoundrel [369]

Answer:

(-6,18)

Step-by-step explanation:

3x + 2y = 18

2y= -3x + 18

y=-3/2 x + 18

give x=0

y=-3/2 *0+18

y=18#

y=18

3x+2(18)=18

3x+36=18

3x=18-36

3x=-18

x=-18/3

x=-6

Question 5 (12 points)

Dima020 [189]

Answer:

see attached for diagram

a) √13

b) √29

c) 4

Step-by-step explanation:

Equation of the circle: $(x + 1)^2 + (y - 3)^2 = 16$

⇒ center = (-1, 3)

⇒ radius = √16 = 4

Distance between 2 points formula:

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

a) let (-1, 3) = $(x_1,y_1)$

let (2, 1) = $(x_2, y_2)$

$\implies \sqrt{(2+1)^2+(1-3)^2} =\sqrt{13}$

b) let (-1, 3) = $(x_1,y_1)$

let (4, 1) = $(x_2, y_2)$

$\implies \sqrt{(4+1)^2+(1-3)^2} =\sqrt{29}$

c) let (-1, 3) = $(x_1,y_1)$

let (3, 3) = $(x_2, y_2)$

$\implies \sqrt{(3+1)^2+(3-3)^2} =4$
