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)
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

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 . . .
[As soon as JUANITO is asleep, BLANCA FLOR gently puts his head down and leaves, taking the thimble with her.]

It cost $3.45 to buy 3/4 lb of chopped walnuts. How much will it cost to buy 7.5 lbs of walnuts?
Answer:
$34.5
Step-by-step explanation:
Turning the 3/4 into a decimal would be .75, .75 can go into 7.5 10 times. You would multiply 10 by the cost $3.45 and you would get $34.5 for 7.5 lbs of walnuts.
(9c2−3cw−6w2)−(−9c2+9cw−w2)
Answer: The answer is [tex]18c^{2}[/tex]-[tex]12cw[/tex]-[tex]5w^{2}[/tex]
Step-by-step explanation:
The first thing you want to do is to add the [tex]9c^{2}[/tex] to the other one. You add instead of subtracting because the second one has a minus sign, and there is a minus sign in front of the parentheses. Two minus' make a plus. Adding these two together gives you a sum of [tex]18c^{2}[/tex].
Next, you want to simplify 9cw. Remember that since 9cw is positive, and there is a minus sign if front of the parentheses, you need to subtract here. Subtracting 3cw and 9cw gives you a difference of [tex]-12cw[/tex]. The new equation is [tex]18c^{2}-12cw[/tex].
Finally, we need to combine -w2 with -6w2. Remember that -w2 has a minus sign in front of it, so you need to add w2 to -6w2. This gives you [tex]-5c^{2}[/tex]. You combine this answer with the two answers above, and you get: [tex]18c^{2}-12cw-5w^{2}[/tex]. I hope this helps.

Answer: C
Step-by-step explanation: 0.571 is greater than 0.4. Therefore, 4/7 is greater than 2/5 and the answer to the question "Is 4/7 greater than 2/5?" is yes. Note: When comparing fractions such as 4/7 and 2/5, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.
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
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

Answer:
1. Yes, all of the measurements are equal
2. A
3. B
4. B
Step-by-step explanation:
1. Congruent shapes have all equal measurements
2. If they are congruent, the sides that align with each other are also congruent
3. If they are congruent, the angles that align with each other are also congruent
4. If they are congruent, then <B and <E are equal to each other... <B = 65 degrees meaning so does <E

Answer:
x
Step-by-step explanation:
because you have to subtract 3x from 4x which leaves x because 1 is just x
Answer:
4x-4=3x
4x-3x=4 - in this step notice how they subtracted 3x from the right side so they could subtract 3x from the left side. By doing so the right side of the equation would be empty and thus is why they added 4 to each side to cancel out the 4 on the left side and add one to the right.

17. Brendan works as a car salesman. He earns a salary of $1,000 per month, plus a commission of 3% on all sales. If he sold $250,000 worth of cars in May, what would his total earning be for the
month?
Answer:
His total earning for the month would be $8,500.
Step-by-step explanation:
In order to calculate the total earnings for the month, you have to find the 3% of the amount of the sales and add the monthly salary:
Monthly earnings=($250,000*3%)+$1,000
Monthly earnings=$7,500+$1,000
Monthly earnings=$8,500
According to this, the answer is that his total earning for the month would be $8,500.

Much appreciated thank you
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

Toni bought some jazz records at $4 each and some classical records at $6 each. If her purchases totaled $46,?
find all possibilities for the number of each type of record that she bought.
Answer:
1 jazz and 7 classical; 4 jazz and 5 classical; 7 jazz and 3 classical; 10 jazz and 1 classical
Step-by-step explanation:
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.
