Answer:

h=10+3*number of years since it was planted

Step-by-step explanation:

You add ten bc it starts off that tall, and bc it grows three feet a year, you multiply 3 by the number of years that has passed.

Given:

The equation of line p is

$y=-\dfrac{1}{3}x-3$

Line p and q are parallel.

To find:

The equation of line q.

Solution:

The slope intercept form of a line is

$y=mx+b$

Where, m is slope and b is y-intercept.

The equation of line p is

$y=-\dfrac{1}{3}x-3$

The slope of the line is $-\dfrac{1}{3}$ .

We know that the slopes of parallel lines are equal.

Line p and q are parallel. So,

Slope of line q = $-\dfrac{1}{3}$

Line q passes through (6,-4) with slope $-\dfrac{1}{3}$ , so the equation of the line is

$(y-y_1)=m(x-x_1)$

Where, m is the slope.

$(y-(-4))=-\dfrac{1}{3}(x-6)$

$y+4=-\dfrac{1}{3}x+2$

$y=-\dfrac{1}{3}x+2-4$

$y=-\dfrac{1}{3}x-2$

Therefore, the equation of line q is $y=-\dfrac{1}{3}x-2$ .

If my friend gives me $1 to buy candy how much would I pay her back?

ANTONII [103]

If your friend gave you $1 you would most likely only need to pay her back $1 unless you're talking about interest.

4. The value of a copy machine is $8500 when it is purchased. After two years its value is $7475. What is its value after 8 year

zepelin [54]

Answer:

3375 is the answer.

Step-by-step explanation: 8500- 1025=7475

so 1025 is every to years so we need to subtract 7475-1025-1025-1025-1025 so each 1025 is 2 yrs.

I hope this works :)

Answer:

x = 9.25

Step-by-step explanation:

It is given that ABC is an isosceles triangle.

m∠A = 43° and m∠C = (6x+13)°

We need to find the value of x.

The sum of a triangle is equal to 180°.

∠A is the vertex angle. For a triangle sum of angle of triangle is equal to 180°

∠A+∠B +∠C=180

43+∠B+(6x+13)°=180

6x+∠B+56=180

6x+∠B = 124

∠B =124-6x

For an isosceles triangle,

∠B = ∠C

124-6x = (6x+13)

124-13 = 6x+6x

111 = 12x

x = 9.25

So, the value of x is 9.25.
