A builder is trying to level out some ground with a front-end loader. He picks up some excess dirt at (9, 16) and then maneuvers through the job site along the rule (x+2, y+3), (x-3, y+4), and then (x+2, y-5) to get to the spot to unload the dirt. Find the coordinates of the unloading point. Write a rule that describes the translation from the loading point to the unloading point.
what is the y intercept of a line that passes through (1,-7) and (5,-25). How do I find it.
Answer:
y- intercept = - 2.5
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 = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)
m = [tex]\frac{-25+7}{5-1}[/tex] = [tex]\frac{-18}{4}[/tex] = - 4.5 , then
y = - 4.5x + c
To find c substitute either of the 2 points into the equation
Using (1, - 7), then
- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5
y- intercept c = - 2.5

Answer:
39 gallons
Step-by-step explanation:
65 gallons ÷ 5 loads = 13 gallons per load
13 gallons per load • 3 loads = 39 loads

1) If (-4 + 3i) is a zero of the function, list another known zero
Step-by-step explanation:
The conjugate of the complex root must also be a zero of the function if the complex root is already a zero.
Conjugate of -4 + 3i is -4 - 3i.
Hence -4 - 3i is also a zero of the function.
Answer:
-4 - 3i
Step-by-step explanation:
If a zero of a function is a+bi, there is at least one other zero, a-bi, called the conjugate.
Using the graph, determine the equation of the axis of symmetry
Answer:
-5 or (-5,0)
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
The solution is : the equation of the axis of symmetry is x= -5 or (-5,0).
What is parabola?The parabola is a plane curve which is mirror symmetrical and is approximately U-shaped. It fits several superficial different mathematical descriptions.

The length of a rectangle is 10 m more than its width if the perimeter of a rectangle is 80 m find the dimensions of the rectangle.(perimeter is just adding up all the sides)
Answer:
width= 15
length=25
Step-by-step explanation:
width= x
length= 10+x
2(10+x+x)= 80
2(10+2x)= 80
20+4x= 80
4x=60
x= 15
width= x= 15
length= 10 +x= 10+15= 25

What is the answer to this math question “X - 3 = 6”
Answer: x = 9
Step-by-step explanation:
x can be equal to 9.
Lets plug in 9 to the variable x, in this equation, x -3 = 6.
x - 3 = 6
9 - 3 = 6 (plugged in 9 for x)
So, x = 9.
Answer:
x-3=6
The correct answer is x=9

Derek bought a cloth for rs 950 .He spent rs 150 for stitching a shirt and sold it at a gain of rs 375 . Find the selling price of the shirt
Answer:
$1473
Step-by-step explanation:
cost of cloth= rs.950
He spent rs.150 for stitching a shirt
total cots= 950+150
total cost=1100
gain= rs.375
we know that
gain= selling price- cost price
substitute
375= selling price- 1100
selling price= 1100+373
selling price=$1473
Hence the selling price is $1473

hello i would like help and the answer to this please; what is the nth term rule of
-5 -4 -1 4 1 1 20 31
Answer:
The nth term of the given sequence
[tex]a_{n} = a_{n-1} + (2n-1)[/tex]
Step-by-step explanation:
Explanation:-
Given sequence -5,-4,-1,4,11,20,31
a₀ = -5
a₁ = a₀ +1 = -5 +1 = -4
a₂ = a₁ + 3 = -4+3 = -1
a₃ = a₂ + 5 = -1 +5 = 4
a₄ = a₃ + 7 = 4 + 7 =11
a₅ = a₄ + 9 = 11+9 = 20
a₆ = a₅ + 11 = 20+11 = 31
a₇ = a₆ + 13 = 31 +13 =44
and so on
The nth term of the given sequence
[tex]a_{n} = a_{n-1} + (2n-1)[/tex]
