Answer:
(1, 3)
Step-by-step explanation:
The solution to a system the point(s) they have in common. These two lines share one point. That point is (1, 3) making it the only solution to the system of equations.
3 lines are shown. A line with points A, F, D intersects a line with points B, F, E at point F. A line extends from point F to point C in between angle B F D.
Which angle is a vertical angle with AngleEFD?
AngleDFB
AngleCED
AngleBFC
AngleAFB
Answer:
your answer would be angleCED
help me pls ☹️☹️☹️☹️
The slope of a line can be found by graph using rise over run ([tex]\frac{rise}{run}[/tex]). Look at the image below to see what this mean.
Rise = vertical
run = horizontal
I took two clear points on the line as seen below and drew a right angle that formed a right triangle with the line.
Now let's count how many units the rise is (look at the second image). This is 3 units
rise = 3
Count the units of the run (third image). This is 1 unit
run = 1
Let's put these two numbers together in the [tex]\frac{rise}{run}[/tex] form:
[tex]\frac{3}{1}[/tex] or simplified = 3
However, this is not the final answer. This is a negative slope, meaning that when you look at the line from left to right (like when you are reading words) the line reaches from the top left corner to the bottom right corner. A positive slope (reading left to right) reaches from the bottom left corner to top right corner.
To signify that the slope is negative you simply add a negative sign to it:
-3

Ali graphs the function f(x) = –(x + 2)2 – 1 as shown. On a coordinate plane, a parabola opens up. It goes through (negative 3, 0), has a vertex at (negative 2, negative 1), and goes through (negative 1, 0). A vertical dashed line at (negative 2, 0) is parallel to the y-axis. Which best describes the error in the graph?
Answer:
The axis of symmetry should be x = 2
Step-by-step explanation:
should be written : f(x) = –(x + 2)^2 – 1
vertex form of the equation:
y = a(x - h)² + k
vertex means highest or lowest part
lowest part is (-2,-1)
axis of symmetry is
x = -b/2a

A rectangular city is 2 miles long and 7 miles wide. What is the distance between opposite corners of the city? The exact distance is ______________ miles How far is it to the closest tenth of a mile? Answer: The distance is approximately ___________ miles.
Answer:
The distance is approximately 10.4 miles.
Answer:
exact distance is = 7.28010988928
rounded to the tenth of a mile is
distance is approximately 7.3 miles
Step-by-step explanation:
hypotenuse of a triangle that's 2 by 7
Pythagorean theorem
a^2 + b^2 = c^2
2^2 + 7^2 = c^2
4 + 49 = c^2
c^2 = 53
c = √53
c = 7.28010988928

subtract the following mixed numbers 4 3/6 - 2 1/3
Answer:
13/6 or 2 1/6
Step-by-step explanation:
In order to solve this, we have to make the denominators equal
To do that, we will need to multiply 1/3 by 2/2 which will get us 2/6
Now that we have like denominators we can convert the mixed fractions to improper fractions:
4 3/6 ---> 27/6
2 2/6 ---> 14/6
Now we can comfortably subtract the two values and simplify if needed
27/6-14/6= 13/6
So:
4 3/6 - 2 1/3 = 13/6 or 2 1/6

Give an example of each of the following, or argue that such a request is impossible.
a. A sequence that has a subsequence that is bounded but contains no subsequence that converges.
b. A sequence that does not contain 0 or 1 as a term but contains subsequences converging to each of these values.
c. A sequence that contains subsequences converging to every point in the infinite set {1, 1/2, 1/3, 1/4, 1/5,...}.
d. A sequence that contains subsequences converging to every point in the infinite set {1, 1/2, 1/3, 1/4, 1/5,...}, and no subsequences converging to points outside of this set.
Answer and Step-by-step explanation:
Solution:
(a) Let (bn) be a bounded sequence of (an) then, Bolzano- Weierstrass theorem,
(bn) contains a subsequence that is converges.
(b) The sequence :
Xn = 1 + (-1) n / 2 + 1/n
Clearly, (xn) does not contain 1 or 0.
If we take sequence (x2n), then it converges to 1 and when we take sequence (x2n+1),
Then it converges to 0.
(c) The sequence:
1
1,1/2
1, 1/2, 1/3
1, 1/2, 1/3, 1/4
i.e
(xn) = (1,1/2, 1, 1/2, 1/3, …)
Then, the subsequence (xn) that is identically ½ in second column and 1/3 is third column and so on.
It has sub sequence that converges to every point in infinite set {1, 1/2, 1/3, 1/4, 1/5…}.
(d) The sequence
{1, 1/2, 1/3, 1/4, 1/5…}
if we take sequence of given set, then, this set converges to zero. This is not contained in it.
If (xn) converges to every point in set {1, 1/2, 1/3 …} then there exists subsequence which converges to 0. And 0 does not belong to given set.

A company designs a circular dartboard such that the target area in the center is surrounded by a safety margin. Federal law requires that the area of the safety margin must be twice the area of the actual target in the center. If the total radius of the dartboard is 3 feet, what is the radius of the circular target in the center? (you must show the algebra for full credit)
Answer:
the radius of the circular target in the center is 2.12 feet
Step-by-step explanation:
the total area of the dartboard is
π x r² = π x 3² = 9π (28.27 ft²)
The area of the actual target in the center needs to be half of the dartboard (4.5 π) (14.14 ft²)
(Small area : 4.5π = π x r²
Divide both sides by π
4.5 = r²
√4.5 = r
r= 2.12132034....... (2.12 feet)
what is 4 times x and pls explain it for me so then I can explain it
Answer:
4x
Step-by-step explanation:
In algebra, to avoid confusing the multiply sign and x, we always just put the terms next to each other to show that they multiply each other. Here, since x is unknown, we can't find a specific answer and therefore just write it as 4x, which means 4 times x.
Sarah went on a 36 mile trip to a soccer game. On the way back, due to road construction she had to drive 18 miles per hour slower. This made the trip take 1 hour longer. How fast did she drive to the soccer game?
Answer:
Hi Suuuman the answer for your deleted question is OP = 7.75
Step-by-step explanation:

Step-by-step explanation:
Answer for this question Sarah went on a 36 mile trip to a soccer game. On the way back, due to road construction she had to drive 18 miles per hour slower. This made the trip take 1 hour longer. 36 = 18 +18(a+1)How fast did she drive to the soccer game? let the returning speed be x mphgoing to game speed = x+18 Answer is 18 km/h while returning
Step-by-step explanation: Distance = 36
1 hour more while returning
time return - time going = 1
36/x - 36/(x+18) = 1
LCD= x ( x + 18 )
multiply by LCD
36 ( x + 18 ) - 36 x = 1 x ( x + 18 )
36*18=
36 x + 648 - 18 x = 1x ^2 + 18 x
648 = 1 x^2 - 18 x
x^2 + 18 x -648 = 0
x^2 +36x-18x-648=0
x(x+36)-18(x+36)=0
(x-18)(x+36)=0
x=-36 or 18
x =18
18 km/h while returning
while going speed = 18+18 = 36 km/h
