Answer: Three years

Step-by-step explanation:

14000=-2000t+20000

Solve for t to find the age of the car

2000t=20000-14000

2000t=6000

T=6000/2000

T=3 years

Hi there

14000=-2000t+20000
Solve for t to find the age of the car
2000t=20000-14000
2000t=6000
T=6000/2000
T=3 years

Hope it helps

3. (x + 1)/4 = 3 / 6
x + 1 = 3/6 x 4 = 2
x = 1

Scale factor = 6 / 4 = 1.5

Ratio of perimeters = 2 : 3

4. x / 21 = 20 / 15
x = 20 / 15 x 21 = 28

Scale factor = 20 / 15 = 4/3

Ratio of perimeters = 3 : 4

X+4Y=-8<br> find the x intercept:<br> find the y intercept: <br> graph the line.
galben [10]

Answer:

x-intercept = (-8, 0)

y-intercept = (0, -2)

Step-by-step explanation:

Given linear equation is: x + 4y = - 8

For x - intercept: Plug y = 0 in the above equation.

\implies x +4(0) = -8\\\\\implies x +0 =-8\\\\ \implies x = -8\\\\ \boxed{\red{\bold{\implies x- intercept = (-8,\:0)}}}

For y - intercept: Plug x = 0 in the given linear equation.

\implies 0 +4y = -8\\\\\implies 4y=-8\\\\ \implies y = \frac{-8}{4}\\\\ \implies y = -2\\\\ \boxed{\purple{\bold{\implies y- intercept = (0,\:-2)}}}

Solve (x + 9)2 = 25.
Rina8888 [55]

Answer:

x = -4 and x = -14

Step-by-step explanation:

Our equation is (x + 9)² = 25

Applying the square root property we would need to take the square root of both sides: \sqrt{(x+9)^{2} } =\sqrt{25}

This give us x + 9 = ±5

Here we have two equations since taking the square root gives us a positive and negative value

Our first equation is x + 9 = 5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -4

Our second equation is x + 9 = -5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -14
