Use the given graph to determine the limit, if it exists. Find limit as x approaches three from the left of f of x. Please include an explanation in your answer, I don't really understand limits so I'll give brainliest to the best explanation.
Answer:
[tex]\displaystyle \lim_{x \to 3^-} f(x) = -1[/tex]
General Formulas and Concepts:
Calculus
Limits
Right-Side Limit: [tex]\displaystyle \lim_{x \to c^+} f(x)[/tex]Left-Side Limit: [tex]\displaystyle \lim_{x \to c^-} f(x)[/tex]Graphical Limits
Step-by-step explanation:
As we approach 3 from the left according to the graph (follow the left graphed line), we see that we approach -1.
∴ [tex]\displaystyle \lim_{x \to 3^-} f(x) = -1[/tex]

Bill has $6 more than Ted. Together they have $32. Write two equations and then solve for the amount of money that bill has.
Someone alr told me the was $19 but I NEED the equation part
Answer:
B= Bill's money
T= Ted's money
B+T=32
T+6=B
Step-by-step explanation:
If you rearrange the first equation you get:
B=32-T
You can then substitute the B in that equation with T+6:
T+6=32-T
combine like terms to get T:
2T+6=32
2T=26
T=13
Then plug in 13 for T in either of the first equations to get B:
13+6=B
19=B
Answer:
Bill has 19$
Step-by-step explanation:
Bill = b
Ted = t
b = t + 6$
b - t = 6$------equation 1
b + t = 32$------equation 2
(equation 1 - equation 2)
(b - b) + (-t - t) = 6 - 32
0 - 2t = -26
-2t = -26
t = -26/-2
t = -26/-2
t= 13$
(put t = 13$ in equation 1)
b - (13) = 6
b - 13 = 6
b = 6 + 13
b = 19$ (Bill = 19$)

9/8m - 1/6m = -4 - 11/3
Answer:
m=-8
Step-by-step explanation:
im assuming the equation is: [tex]\frac{9}{8} m-\frac{1}{6} m=-4-\frac{11}{3}[/tex]
find common denominators i choose 24
9/8 = 27/24
1/6 = 4/24
11/3 = 88/24
4 = 96/24
now start solving:
(Note that because denominators are the same you can just ignore them and focus on the numerator)
simplify (27/24)m - (4/24)m to (23/24)m
simplify -(96/24) - (88/24) to -184/24
now you are left with 23/24 m = -184/24
get rid of denominators 23m=-184
Divide -184 by 23 to get m= -8
Point M is the midpoint of FG. Can the value of variable a be determined? Explain F(b+1, a+2). M(3,5). G(2a, 3b+3)
Answer:
YES, the value of a is 2Step-by-step explanation:
Given the coordinates F(b+1, a+2, M(3,5) and G(2a, 3b+3), if M is the midpoint of F and G then, to get the value of a and b we will use the formula for calculating the midpoint a shown;
M(X, Y) = (x₁+x₂/2, y₁+y₂/2)
X = x₁+x₂/2 and Y = y₁+y₂/2
From the given coordinates x₁ = b+1, y₁ = a+2, x₂ = 2a, y₂ = 3b+3, X = 3 and Y = 5
Substituting the given parameters into the formula, we can get the value of a and b as shown;
3 = b+1+2a/2
6 = 2a+b+1
2a+b = 5 ............... 1
Similarly, for the Y coordinate;
5 = a+2+3b+3/2
10 = a+2+3b+3
a+3b = 10-2-3
a+3b = 5 ........ 2
Solving equation 1 and 2 simulatneously using elimination method
2a+b = 5 ............... 1 * 1
a+3b = 5 ........ 2 * 2
---------------------------------------------------------
2a+b = 5 ...........3
2a +6b = 10.......... 4
subtract 3 from 4
b - 6b = 5-10
-5b = -5
b = -5/-5
b = 1
substitute b =1 into equation 2 to get a;
a + 3b = 5
a + 3(1) = 5
a = 5-3
a = 2
From the calculation above it is seen that the value of variable a can be determined and it is equivalent to 2
Answer:
To determine the value of a, set up and solve a system of equations in two variables. The value of a is 2

Ann, Emily, and Bob collect stickers. They have a total of 70 stickers in the ratio 2:3:5, respectively. How many stickers does each child have?
Answer:
The stickers are divided by groups of
2/10, 3/10 and 5/10
2/10 * 70 = 14
3/10 * 70 = 21
5/10 * 70 = 35
14 + 21 + 35 = 70
So, the stickers are allotted to the 3 children in a group of
14 to one child, 21 to another child, and 35 to the third child.

What are the coordinates of point B on AC such that the ratio of AB to AC is 1:3
Answer:
B) (2/3, 3 2/3)
Step-by-step explanation:
I think whoever write this problem thought the distance from A to C was 10. It’s not. It’s 10.77. (See below). But following what they did, the answer must be B) (2/3, 3 2/3)
First, find the distance from A to C.
4²+10²=c²
16+100=c²
116=c²
c=√116
10=10.77
The coordinates of point B on AC such that the ratio of AB to AC is 1:3 is (2/3, 3 2/3) option (B) is correct.
What is a segment bisector?A segment bisector is a line, ray, line segment, or point that divides a line segment into two equal halves at its center.
It is given that:
The line segment shown in the picture is in the ratio of AB to AC is 1:3
AB : AC = 1 : 3
m : n = 1 : 3
The coordinate of point A is (2, 7)
The coordinate of point C is (-2, -3)
Let the coordinate of the point B is (x, y)
m = 1
n = 2
x1 = 2
x2 = -2
y1 = 7
y2 = -3
x = (-2+4)/3
x = 2/3
y = (-3+14)/3
y =11/3
y = 3 2/3
B = (x, y) = (2/3, 3 2/3)
Thus, the coordinates of point B on AC such that the ratio of AB to AC is 1:3 is (2/3, 3 2/3) option (B) is correct.
The options are:
A. (1/3, 2 5/6)
B. (2/3, 3 2/3)
C. (-2/3, 1 1/6)
D. (-2/3, 1/3)

there are five united states athletes, four russian athletes, three french athletes, and one german athlete. How many rankings of the 13 athletes are there
Answer:
There are 6227020800 possible rankings
Step-by-step explanation:
Given
[tex]Athletes= 13[/tex]
Required
Number of Rankings
Let the number of athletes be n;
Since each athlete can only take one position at any given instance, the number of rankings is [tex]n![/tex]
Where [tex]n = 13[/tex]
Substitute 13 for n
[tex]13! = 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 *3 * 2 *1[/tex]
[tex]13! = 6227020800[/tex]
Hence, there are 6227020800 possible rankings
Give two points with integer coordinates that have a slope of 10/7 between them
Answer:
(0,0) and (7,10)
Step-by-step explanation:
recall that the slope - intercept form of a linear equation can be given as
y = mx + b
where m = slope and b = y intercept
in our case, we are given that slope, m = 10/7, hence our equation becomes
y = (10/7) x + b
since we are not given any information about the y-intercept, we can simply pick a value for b that is most convenient for us.
We pick b = 0, hence the equation simplifies to:
y = (10/7) x ----- eq 1
we can see immediately that if x = 0, y must also = 0
proof if x = 0:
y = (10/7)(0) =0
since 0 is an integer, then (0,0) must be the first point.
we can also observe that for y to be an integer, we must get rid of the denominator 7. We can do this by multiply the right side by 7. Hence we let x = 7:
y = (10/7) x 7
y = 10
hence (7,10) is the second point.

Find an equation of the line that is perpendicular to 2x-3y=3 that passes through the point (1,2)
Answer:
The answer is
[tex]3x + 2y = 7[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the perpendicular line we must first find the slope of the original line
From the question the original line is
2x - 3y = 3
Write the equation in the general form above
That's
3y = 2x - 3
y = 2/3x - 1
Comparing with the general equation above
Slope = 2/3
Since the lines are perpendicular to each other the slope of the perpendicular line is the negative inverse of the original line
Slope of perpendicular line = - 3/2
So the Equation of the line using point
( 1 , 2) and slope - 3/2 is
[tex]y -2 = - \frac{3}{2} ( x - 1) \\ 2y - 4 = - 3(x - 1) \\ 2y - 4 = - 3x + 3 \\ 3x + 2y - 4 - 3 = 0[/tex]
We have the final answer as
[tex]3x + 2y = 7[/tex]
