Answer:
y=1/2x-21/2
Step-by-step explanation:
f(x) contains (3, -9) and (-1, -11)
slope : (-9-(-11)))/(3-(-1))
2/4=1/2
slope : 1/2
y=1/2x+b
-9=3/2+b
b=-21/2
y=1/2x-21/2

How are key features of a linear function identified and interpreted from an equation?
An increasing linear function results in a graph that slants upward from left to right and has a positive slope. A decreasing linear function results in a graph that slants downward from left to right and has a negative slope. A constant linear function results in a graph that is a horizontal line.

Answer:
C = 0.35x + 100
Step-by-step explanation:
0.35 is the cost per mile, and x is the number of miles. Say if x is 10, meaning you went 10 miles, you would multiply that by 0.35 to get a cost of $3.50. So, use 0.35x . The $100 is added on because it doesn’t matter how many miles were driven, you still have to pay at least that much per day.

Answer:
To find the first blank number, you can use reverse operations. Something + 7 must equal 3. So, the blank number is 7 subtracted from 3.
3-7=-4
The first blank number is -4. To find the second blank number, add 10 to the first blank number (-4).
-4+10=6
The second blank number is 6.

[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
First, it is going upwards from left to right so we know it'll be positive. Then we do the following:
[tex]\frac{rise}{run}=\frac{change.in.y}{change.in.x}=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}=\frac{0--6}{4-0} =\frac{0+6}{4-0} =\frac{6}{4} =\frac{3}{2}[/tex]
("." in the second fraction is for separate words)
So the slope is [tex]\frac{3}{2}[/tex]

1. The distance from a point on the ground to the
base of the tree is 18m.
The distance from a point on the ground to the
top of a tree is 20m. Calculate the height of the
tree.
Answer:
8.7m
Step-by-step explanation:
Let's say the height of the tree is h and apply pythagoras:
18² + h² = 20² =>
h = √76 ≈ 8.7m

2) The circumference of a circle is 8cm . What is the DIAMETER of the circle?
A) 2 cm
B) 4 cm
c) 6 cm
D) 8 cm
Answer:
Step-by-step explanation:
D
The circumference of circle a is 3 times the circumference or circle b. Find circumference of circle b. Diameter of circle a is 27.
Answer:
9π
Step-by-step explanation:
Let a = circumfrence of circle a
b = circumfrence of circle b
a = 3b
circumference = 2πr
diameter = 27
radius = 27/2 (radius is half of the diameter)
a = 2π(27/2)
a = 27π
Plug in the new a
27π = 3b
Divide both sides by 3
27π/3 = 3b/3
b = 9π

Answer:
a) -4
b) 11
c) a(1) = -4; a(n) = a(n-1) +11 (Maybe you want an = -4+11(n-1).)
d) 95
Step-by-step explanation:
See the attached.
a) The value of a1 is given in the problem statement. It is -4.
__
b) If we take "d" to mean the common difference between terms, it is the value added to one term to get the next term. The recursive formula shows that value is 11.
__
c) The iterative rule for the sequence is given in the problem statement.
We suspect the intention is to ask for the explicit rule. That rule has the form ...
an = a1 +d(n -1)
Using the values of a1 and d, we get the explicit rule ...
an = -4 +11(n -1)
__
d) The recursive/iterative rule requires you find all previous terms in the sequence before you can learn the 10th term. The explicit rule allows you to substitute n=10 and compute the 10th term directly:
a10 = -4 +11(10 -1) = -4 +99 = 95
The tenth term is 95.

Additional comment
We'd rather not have to try to guess the intended question. Perhaps you should discuss this question with your teacher. (recursive vs. iterative vs. explicit)
Tim is choosing between two cell phone plans that offer the same amount of free minutes. Verizon’s plan charges $39.99 per month with additional minutes costing $0.45. AT&T’s plan costs $44.99 with additional minutes at $0.40. How many additional minutes, a, will it take for the two plans to cost the same?

measurement is 29 inches, find the height.
Give your answer rounded to 1 decimal place.
inches
Answer:
h = 16.7 inches
Step-by-step explanation:
h² + (h + 7)² = 29²
h² + h² + 14h + 49 = 841
2h² + 14h - 792 = 0
h² + 7h - 396 = 0
quadratic formula
h = (-7 ±√(7² - 4(1)(-396))) / (2(1))
h = (-7 ± 40.4103) / 2
h = -23.705 which we ignore as negative length makes no sense
(although 23.705 inches will turn out to be the width of our rectangle)
or
h = 16.705
Which graph is growing at a slower rate?
graph a or b
Answer:
B.
Step-by-step explanation:
The graph of b is a linear graph, meaning it's value will increase at the same rate. The graph of a, however, appears to be exponential. This means that a will increase at a rapidly higher rate that b over time. You can also tell by just looking. You can see graph a has overtaken b in the same amount of time.

#7: Equivalent or Not?
For each pair of equations, determine if the equations are equivalent. Then determine whether the second equation is the result of a valid operation on the first. If so, what is the operation?
1. 7 + 5x = 3 - 2x and 7 + 7x = 3
2. 3 (x – 4) = 15 and x-4 = 15
3. x2 = 6x and x = 6
4. (x+5) = 10 and 1 = 10(x – 5)
Equivalent equations are simply equations that have the same value, irrespective of their form
7 + 5x = 3 - 2x and 7 + 7x = 3 are equivalent3(x – 4) = 15 and x-4 = 15 are not equivalent[tex]\mathbf{x^2 = 6x}[/tex] and [tex]\mathbf{x = 6}[/tex] are equivalent[tex]\mathbf{x+5 = 10}[/tex] and [tex]\mathbf{1 = 10(x - 5)}[/tex] are not equivalent1. 7 + 5x = 3 - 2x and 7 + 7x = 3
Start by solving for x in both equations
[tex]\mathbf{7 + 5x = 3 - 2x}[/tex]
Collect like terms
[tex]\mathbf{2x + 5x = 3 - 7}[/tex]
[tex]\mathbf{7x = - 4}[/tex]
Divide both sides by 7
[tex]\mathbf{x = -\frac 47}[/tex]
[tex]\mathbf{7 + 7x = 3}[/tex]
Collect like terms
[tex]\mathbf{7x = 3-7}[/tex]
[tex]\mathbf{7x = - 4}[/tex]
Divide both sides by 7
[tex]\mathbf{x = -\frac 47}[/tex]
The values of x in both equations are the same;
Hence, 7 + 5x = 3 - 2x and 7 + 7x = 3 are equivalent
2. 3 (x – 4) = 15 and x-4 = 15
Rewrite the first equation as follows
[tex]\mathbf{3 (x - 4) = 15 }[/tex]
Divide both sides by 3
[tex]\mathbf{x - 4 = 5 }[/tex]
In the second equation, we have:
[tex]\mathbf{x-4 = 15}[/tex]
The values of x - 4 are not the same in both equations.
Hence, 3(x – 4) = 15 and x-4 = 15 are not equivalent
3. x2 = 6x and x = 6
Solve for x in the first equation as follows:
[tex]\mathbf{x^2 = 6x}[/tex]
Divide both sides by x
[tex]\mathbf{x = 6}[/tex]
The results of both equations are the same.
Hence, [tex]\mathbf{x^2 = 6x}[/tex] and [tex]\mathbf{x = 6}[/tex] are equivalent
4. (x+5) = 10 and 1 = 10(x – 5)
Solve for x in the first equation as follows
[tex]\mathbf{x+5 = 10}[/tex]
[tex]\mathbf{x = 5}[/tex]
Solve for x in the second equation as follows
[tex]\mathbf{1 = 10(x - 5)}[/tex]
Divide both sides by 10
[tex]\mathbf{0.1 =x - 5}[/tex]
Add 5 to both sides
[tex]\mathbf{x = 5.1}[/tex]
The values of [tex]\mathbf{x+5 = 10}[/tex] and [tex]\mathbf{1 = 10(x - 5)}[/tex] are not the same
Hence, [tex]\mathbf{x+5 = 10}[/tex] and [tex]\mathbf{1 = 10(x - 5)}[/tex] are not equivalent
