Find the point-slope equation for
the line that passes through the
points (1, -9) and (-10, 101). Use
the first point in your equation.
Answer:
y - (-9) = -10 (x - 1)
Step-by-step explanation:
y = mx + b
m (slope) = (y'-y) / (x'-x) = (101 - (-9)) / (-10) - 1) = 110/(-11) = -10
pass (1 , -9)
m = (y - (-9)) / (x - 1) = -10
y - (-9) = -10 (x - 1)

Peter is driving from Pensacola to Jacksonville
Answer: Peter had the fastest interval at D.
Step-by-step explanation:
Peter traveled roughly 180 miles in 3 hours for point D, thus making him the fastest.
Peter had the fastest interval at D.
What is speed ?Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
From Point A to Point B Peter traveled roughly 30 miles in 30 minutes.
From Point B to Point C Peter traveled roughly 130 miles in 2 hours and 30 minutes.
From Point C he didn't move in distance but the hours moved so c is out.
From Point C to Point D, Peter traveled roughly 180 miles in 3 hours.
Therefore D Peter had the fastest interval at D.

Answer:
x²-7x+12
Step-by-step explanation:
When doing these types of problems, you have to multiply each term with each other.
Lets take a look at this.
We have to multiply each term with each other, so x times x =x²
x times -3=-3x
x times -4=-4x
-3 times -4=12
now we add them all up to get
x²-7x+12
Dos libras de carne de res y dos de chivo cuestan $334 pesos, si duplico la libra de carne de res y una libra de chivo cuestan $420 pesos. ¿Cuál es el precio por libra de cada producto?
Answer:
El precio por libra de la carne de res es $84.33 y el precio por libra de chivo es $82.67.
Step-by-step explanation:
Con la información proporcionada puedes escribir las siguientes ecuaciones:
2x+2y=334 (1)
4x+y=420 (2), donde:
x es el precio por libra de carne de res
y es el precio por libra de chivo
Primero, puedes despejar x en (1):
2x=334-2y
x=334/2-2y/2
x=167-y (3)
Ahora, debes reemplazar (3) en (2) y despejar y:
4(167-y)+y=420
668-4y+y=420
668-3y=420
668-420=3y
248=3y
y=248/3
y=82.67
Finalmente, puedes reemplazar el valor de y en (3) para encontrar el valor de x:
x=167-y
x=167-82.67
x=84.33
De acuerdo a esto, la respuesta es que el precio por libra de la carne de res es $84.33 y el precio por libra de chivo es $82.67.

easy algebra question below first correct answer gets brainliest
Answer:
10
Step-by-step explanation:
We solve using Pythagoras Theorem. Pythagoras Theorem is used to solve for the missing side of a right angled triangle.
The formula for Pythagoras Theorem =
c² = a² + b²
c = √a² + b²
Where c is the longest side
From the above diagram, we are looking for c
c = ?
a = 6
b = 8
Hence,
c = √6² + 8²
c = √36 + 64
c = √100
c = 10
Therefore, side c = 10

Answer:
70° angle because it's not an obtuse angle so it wouldn't be C, D, or E and 25° is to small so the answer is B
Answer:
70 degrees
Step-by-step explanation:
90 degrees is a right angle, which is just straight up, and has a. square symbol. So, we can use that to compare the answers. Anything over 90 degrees would have its angle tilt to the left. So, anything over 90, like the ones at 100 degrees are wrong. 20 would be really close to the bottom. So, its 70

Shazia sells 25x^2+5x+5 flowers in one day. If she sells the same number of flowers each day for rs 5x each , how much money will she have at the end of five days
Anyone help
Answer:
[tex]Total = 625x^3 + 125x^2 + 125x[/tex]
Step-by-step explanation:
Given
[tex]Flowers = 25x^2 + 5x + 5[/tex]
[tex]Unit\ price = 5x[/tex]
Required
The total price for 5 days
First, calculate the total for a day.
[tex]1\ day = Unit\ price * Flowers[/tex]
[tex]1\ day = 5x * (25x^2 + 5x + 5)[/tex]
Open bracket
[tex]1\ day = 125x^3 + 25x^2 + 25x[/tex]
For 5 days, the total will be.
Total = days * sales of a day
So, we have:
[tex]Total = 5 * [ 125x^3 + 25x^2 + 25x][/tex]
[tex]Total = 625x^3 + 125x^2 + 125x[/tex]
A maple tree is 16 yards tall and its shadow is 12 yards long. A nearby observation tower is 12 yards tall. How long is the observation tower's shadow? Write your answer as a whole number or a decimal. Do not round.
Answer: 9 yards
Step-by-step explanation:
Given
The maple tree is 16 yards tall and its shadow is 12 yards tall
Suppose the angle made by the maple tree is x
[tex]\Rightarrow \cos x=\dfrac{12}{16}[/tex]
For the tower also, the angle made by the tower and its shadow is x
Suppose the length of the shadow is y
[tex]\Rightarrow \cos x=\dfrac{y}{12}[/tex]
Substitute the value of [tex]\cos x[/tex]
[tex]\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}[/tex]
10 people take 8 days to build a wall.
How long will it take 4 people to do the same job?
Answer:
20 days
Step-by-step explanation:
10 to get to 4 needs to be divided by 2.5 so we do the opposite to the other side since with fewer people it would take longer. (2.5 times longer).
10/2.5 = 4
8x2.5 = 20 days

Find the value of y that makes 120y a perfect square
Step-by-step explanation:
y = 30
120y = 120×30 = 3600
√3600 = 60
The value of y is 60 which makes 120y a perfect square.
What is a perfect square?A perfect square is a number that represents the square of a natural number.
For example 9,16,36,64,121 etc
Here given that we have to calculate the value of y for which 120y will be a perfect square.
so 120y = n² where n is the natural number
For calculating the value of y first factorize 120
120= 2*2*2*3*5
= 2² * 2*3*5
=4 *30
from the above, it is clear that 120 can be written as 4*30 where 4 is a perfect square but 30 is not a perfect square.
So if we multiply 30 by 120 then the product has 2²*30² which will be a perfect square.
Therefore the value of y is 30 for which 120*30=n² where n=60.

Hey! Could someone explain to me how to find the perimeter of this figure? It would be greatly appreciated!
Answer:
3/2 pi + 12
Step-by-step explanation:
In this figure, we have 4 sides and one curve. The total length of the four sides is 3 x 4 = 12. To find out the length of the curve, we need to find the angle of the top figure. Since it is next to a square, that means the angle that is farthest from the curve is 90 degrees.
The formula for finding an angle of a curve is n/360 x 2 pi x radius, where n is the angle.
The radius of the arc is 3, because at the bottom we see the width of the figure is 3.
Substituting our known values, we have 1/4 x 2 x pi x 3 = 6 x 1/4 x pi = 3/2 x pi.
Therefore, our answer is 3/2 pi + 12
