Answer:
The y-intercept is 2.
Step-by-step explanation:
We can find the y-intercept by looking at the linear equation y = mx + b.
m = slope
b = y-intercept
====================================================
Let's find the y-intercept of this line.
You should notice that the equation is written in Slope-Intercept Form:
[tex]\bigstar{\boxed{\pmb{y=mx+b}}}[/tex]
Where
m -> slope
b -> y-intercept
In the equation y=mx+b, the y-intercept is b, and in the equation y=3x+2, 2 is the y-intercept.
=========================================================

The roads that connect three buildings form a right triangle. Use the image to find the distance between the library and the museum.
Answer:400 yards
Step-by-step explanation:Let L represents the position of library, R represents the restaurant and M represents the museum,
Since, By the given diagram,
∠MLR = 90°,
LR = 300 yd,
RM = 500 yd,
So, by the Pythagoras theorem,
By substituting the values,
Hence, the distance between library and museum is 400 yards.

A fish and wildlife management organization uses a GIS (Geographic Information System) to store and analyze data for the parcels of land it manages. All of the parcels are mapped on a grid in which 1 unit represents 1 acre. If the coordinates of the corners of a parcel are (-8, 10), (6, 17) and (2, -4), how many acres is the parcel? a. 150 acres c. 133 acres b. 125 acres d. 167 acres
Answer:
c. 133 acres
Step-by-step explanation:
Given: coordinates of the corners of a parcel are (-8, 10), (6, 17) and (2, -4)
To find: area of the parcel
Solution:
Using heron's formula,
area of triangle joining coordinates [tex](x_1,y_1),(x_2,y_2),(x_3,y_3)[/tex] is equal to [tex]\frac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|[/tex]
Let [tex](x_1,y_1)=(-8,10)\,,\,(x_2,y_2)=(6,17)\,,\,(x_3,y_3)=(2,-4)[/tex]
Area of triangle (parcel) [tex]=\frac{1}{2}|-8(17+4)+6(-4-10)+2(10-17)|\\[/tex] [tex]=\frac{1}{2}|-8(21)+6(-14)+2(-7)|\\ =\frac{1}{2}|-168-84-14|\\ =\frac{1}{2}|-266|\\ =133\,\,acres[/tex]

1521 orange trees are planted in a garden in such a manner that there are as many trees in a row as there are rows in the garden. The number of trees in each row is
Answer: 39
Step-by-step explanation:
Total number of orange trees = 1521
Note :
There are as many trees in a row as there are rows in the garden.
Therefore :
Number of rows in the garden = number of trees in a row
Let the number of rows in the garden = y
Hence, the number of trees in a row also = y
Total number of trees in the garden = number of trees in a row × number of rows in the garden
Total number of trees in the garden = y × y
1521 = y × y ; 1521 = y^2
y = √1521
y = 39
Answer:
no.f trees in each row =39Step-by-step explanation:
Total number of orange trees = 1521
Note :
There are as many trees in a row as there are rows in the garden.
Therefore :
Number of rows in the garden = number of trees in a row
Let the no.f trees in each row =x
let the no.f rows=x
therefore total no.f trees =x raised to 2
x raised to 2 =1521
therefore x=39
there fore no.of rows =39
no.f trees in each row =39Use the distributive property to expand Negative 4 (Negative two-fifths + 3 x). Which is an equivalent expression?

2-4(3x-y)=8(4-y)-39x and 8(4-y)-39x=6(y-x)
Answer:
X = -(146/123) , Y = 21/41
Step-by-step explanation:
2-4(3x-y) = 8(4-y)-39x2-12x-4y = 32-8y-39x
39x-12x+8y-4y = 32-2
27x+4y = 30
27x+4y-30 = 0
8(4-y) -39x = 6(y-x)32-8y-39x = 6y-6x

A delivery service claims that orders arrive before noon 90% of the time. If Amy uses the delivery service 20 times, how many times can she predict the deliveries will arrive before noon? Is the claim accurate if her packages arrive after noon 4 times?
Answer:
They claim that 90% of the times, the orders arrive in time.
Then, out of N orders, (90%/100%)*N of them will arrive in time.
Here we have that N = 20
then the number that arrives in time is:
(90%/100%)*20 = 18
Now, experimetally we see that 4 times her packages arrived after noon (so 16 times the packages arrived in time), so we can calculate the experimental percentage as:
(X/100%)*20 = 16
X = (16/20)*100% = 80%
so the percentages doesn't match, so it the claim is not really accurate, but this is a small sample, so if the number of times that she uses the delivery increases, we may see that the experimental percentage gets closer to the claimed percentage.
A canvas shopping bag has a mass of 600 grams. When 5 cans of equal mass are put into the bag, the filled bag has a mass of 4 kilograms. What is the mass of each can in grams?
Answer:
Mass of each can = 680 grams
Step-by-step explanation:
Mass of a canvas shopping bag = 600 grams Or [tex]\frac{600}{1000}[/tex] Kilograms
= 0.6 Kilograms
Let the mass of each can = w Kilograms
Then the mass of 5 cans = 5w Kilograms
Total mass of the bag when these cans were kept in the bag = 4 Kilograms
(5w + 0.6) = 4
5w + 0.6 - 0.6 = 4 - 0.6
5w = 3.4
w = [tex]\frac{3.4}{5}[/tex]
= 0.68 Kilograms
= [tex]0.68\times 1000[/tex]
= 680 grams
Therefore, mass of each can = 680 grams

680

Five times the sum of a number and 3 is the same as 3 times the difference of twice the number and 1.
What is the number?
Answer:
12
Step-by-step explanation:
5(x+3) = 3(2x-1)
5x+15 = 6x-3
15-3 = 6x-5x
12 = x
x = 12
The number should be 12.
Given that,
Let us assume the number be x.Five times the sum of the number & 3 should be the same because 3 times is the difference of the twice of the number and 1.Based on the above information, the following equation should be made:
5(x+3) = 3(2x-1)
5x+15 = 6x-3
15-3 = 6x-5x
12 = x
x = 12
Therefore we can conclude that the number is 12.

Please help!! Urgent! Due soon! - A bedroom is initially squat-shaped with each side x feet long. The room is then expanded so that the length of the room is increased by 3 feet, and the width increased by 4 feet. Choose the expression which represents how much bigger the area of the new bedroom is than the old bedroom.
Answer:
The second one; x²+7x+12
Step-by-step explanation:
So, since the beginning lengths of the square is x and x, the area of the square is x².
But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).
Finally, you would multiply them together to get the equation you would use to find the new area.
For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.
