Answers
Answer:
8. The coordinates (0,0) represent the fact that when 0 minutes has passed, the horses have gone 0 miles because they hadn't started yet.
9. From the graph, it looks like horse A takes 4 minutes and horse B takes 2.5 minutes (aka 2 minutes and 30 seconds) to travel 1 mile.
10. For A: y = (1/4)x
For B: y = (2/5)x
11. For A: 3 miles
For B: (24/5) miles, or 4 and (4/5) miles.
12. Can't see the entire problem sorry.
Step-by-step explanation:
9. You find this by going to y=1 and look towards the right till you find the point the line intersects with y=1. Then find the x value by finding the corresponding number on the x axis.
10. A linear function will look something like this: y = mx+b, where y is the y value, x is the x value, m is the slope, and b is the y-intercept. Since both lines start from 0, you don't have to write the y-intercept since there's no point in writing +0. To find slope, you find delta y over delta x. Basically just find the difference of two y values and the difference of two x values from the same coordinate in the same order. I know that sounds really confusing but your teacher will probably teach this later on.
11. x represents the time, so just substitute x as 12 in the equation.

Mia and her children went into a grocery store and where they sell apples for $2 each and mangos for $1.50 each. Mia has $20 to spend and must buy no less than 9 apples and mangos altogether. If Mia decided to buy 3 mangos, determine the maximum number of apples that she could buy. If there are no possible solutions, submit an empty answer.
Answers
Answer:
The maximum amount of apples she could buy is 7
Step-by-step explanation:
3 mangos would be 4.50 dollars. Subtract that from her current amount of money (20 dollars). You would get 15.5 dollars. Then, find how many apples she can buy with 15.5 dollars. You can't buy 8 because that would be above 15.5. So do the next smallest amount, 7.

Answer:
∠1 = 43
∠2 = 17
∠3 = 120
∠4 = 60
∠5 = 60
∠6 = 60
∠7 = 17
∠8 = 120
∠9 = 43
Step-by-step explanation:
11) ΔABC is isosceles triangle. In isosceles triangle two sides are equal and angles opposite to two sides are equal {Isosceles triangle property}
∠C = ∠A
9x - 47 = 4x + 3
9x - 4x - 47 = 3
5x - 47 = 3
5x = 3 + 47
5x = 50
x = 50/5
x = 10
∠1 = 4x +3 = 4*10 + 3 = 40 + 3
∠1 = 43
∠9 = 43
ΔDBE is equilateral. So all angles are equal in equilateral.
Each angel in equilateral triangle = 180÷ 3 = 60
∠4 = ∠5 = ∠6 = 60
∠3 + ∠4 = 180 {linear pair}
∠3 + 60 = 180
∠3 = 180 - 60
∠3 = 120
∠6 + ∠8 = 180 {linear pair}
60 + ∠8 = 180
∠8 = 180 - 60
∠8 = 120
In ΔABD,
∠1 + ∠2 + ∠3 = 180 {angle sum property of triangle}
43 + ∠2 + 120 = 180
∠2 + 163 = 180
∠2 = 180 - 163
∠2 = 17
In ΔBEC,
∠7 +∠8 +∠9 = 180 {angle sum property of triangle}
∠7 + 120 + 43 = 180
∠7 + 163 = 180
∠7 = 180 - 163
∠7 = 17

Read the excerpt from Blanca Flor.
The Narrator. Juanito took the thimble and started to carry the water from the lake. He worked as hard as he could, but soon he began to realize that the job really was an impossible one, and he knew he was doomed. He sat down and began to cry because his luck had abandoned him and because his parents' blessings offered no protection in that evil place. Blanca Flor watched Juanito's valiant effort to move the water. As she watched him crying, her heart was touched, and she decided to use her powers to help him. She knew that it was very dangerous to use her powers to help Juanito and to cross Don Ricardo, but she felt it was finally time to end her own torment. As Juanito cried, Blanca Flor took out her brush and began to brush his hair. She cradled Juanito in her arms and her soothing comfort soon put him to sleep . . .

Lime FG goes through the points (4,9) and (1,3). Which equation represents a line that is perpendicular to FG and passes through the point (2,0)
Answers
Answer:
First, we know that:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then for line FG = f(x), we know that it passes through the points (4, 9) and (1, 3)
Then the slope is:
a = (9 - 3)/(4 - 1) = 6/3 = 2
f(x) = 2*x + b
To find the value of b we can use one of the points, i will use the point (1, 3)
this means that when x = 1, f(1) = 3.
Then:
f(1) = 3 = 2*1 + b
3 = 2 + b
3 - 2 = b = 1.
The line FG is f(x) = 2*x + 1.
For a general linear equation:
y = a*x + b
The equation for a perpendicular line is:
y = (-1/a)*x + c
We know that:
f(x) = 2*x + 1
The perpendicular line will be something like:
g(x) = (-1/2)*x + c
To find the value of c, we use the fact that this line passes through the point (2, 0), then:
g(2) = 0 = (-1/2)*2 + c
0 = -1 + c
1 = c
The line is: g(x) = (-1/2)*x + 1

The temperature in Anchorage, Alaska was 4 degrees Fahrenheit at 2:00 PM. The temperature dropped 2.5 degrees per hour until 9:00 PM. The temperature dropped another 9 degrees by midnight.
How much colder was it at midnight than at 2:00 PM?
A.) 17.5 degrees colder
B.) 26.5 degrees colder
C.) 22.5 degrees colder
D.) 18.5 degrees colder
Answers
Answer:
It was 26.5 degrees colder at midnight than at 2:00 pm
Step-by-step explanation:
We have that:
At 2:pm, it was 4 degrees.
The temperature dropped 2.5 degrees per hour until 9:00 pm.
From 2pm to 9pm, there are 7 hours. 2.5 per hour, it was 4 degrees at 2 pm.
So at 9 pm the temperature is:
4 - 2.5*7 = -13.5
The temperature dropped another 9 degrees by midnight.
At midnight, the temperature is -13.5 - 9 = -22.5 degrees
How much colder was it at midnight than at 2:00 pm?
2pm: 4 degrees
Midnight: -22.5 degrees
How much coldren
-22.5 - 4 = -26.5
It was 26.5 degrees colder at midnight than at 2:00 pm
Answer:
B. 26.5
Step-by-step explanation:
2:00 PM - 9:00 PM = 7 hours
7 * 2.5 = 17.5
17.5 + 9 = 26.5

Turn the problem into an equation with x representing the number of jazz records and y as the number of classcial records. The equation will look like this: 4x+6y=46
We can graph this equation
The possibilites are when both the x and y are positive and are whole numbers because you can't buy negative records and you can't buy fractions of records.

Step-by-step explanation:
You combine like terms

8y -9y = -1y
so your answer is anything that is the same as -1 - y
2(10+4y-7y-19) =2( -3y-9) = -6y-18 NO
2(10 +4y) - 3(3y-7) = 20 +8y - 9y +21 = -y +41 NO
4(5+2y-5y-17)= 4(-3y -12) = -12y -48 NO
4(5+2y) - 3(3y+7) = 20 +8y - 9y -21 = -1 = y YES
-(y+1)= -y-1 YES
-(1-y) = -1+y NO
