Marty and Ethan both wrote a function, but in different ways.
Marty
y plus 3 equals StartFraction 1 Over 3 EndFraction left-parenthesis x plus 9 right-parenthesis.
Ethan
A two column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 9.2, 9.6, 10, 10.4.
Whose function has the larger slope?
Marty’s with a slope of 2/3
Ethan’s with a slope of 2/5
Marty’s with a slope of 1/3
Ethan’s with a slope of 1/5
Answer:
Marty's with a slope of 1/3
Step-by-step explanation:
The functions Marty and Ethan wrote are analyzed the find the slope of each of the function
The equation Marty wrote is presented here as follows;
[tex]y + 3 = \dfrac{1}{3} \cdot\left (x + 9 \right)[/tex]
Marty's equation can be written in slope and intercept form, y = m·x + c, as follows;
[tex]y = \dfrac{1}{3} \cdot\left (x + 9 \right) - 3[/tex]
[tex]y = \dfrac{1}{3} \cdot x + \dfrac{9}{3} \right) - 3 = \dfrac{1}{3} \cdot x + 0[/tex]
[tex]y = \dfrac{1}{3} \cdot x[/tex]
By comparison, the slope of the function, m = 1/3
[tex]\therefore \ the \ slope \ of \ Marty's \ function, \ y + 3 = \dfrac{1}{3} \cdot\left (x + 9 \right), \ m =\dfrac{1}{3}[/tex]
Marty's function has a slope of m = 1/3
Ethan has the following two column table;
[tex]\begin{array}{rl}x&y\\-4&9.2\\-2&9.6\\0&10\\2&10.4\end{array}[/tex]
The slope, m, of the data in the above table is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Taking any two points, (x₁, y₁) = (-4, 9.2), and (x₂, y₂) = (2, 10.4), we get;
[tex]Slope, \, m =\dfrac{10.4-9.2}{2-(-4)} = \dfrac{1.2}{6} = \dfrac{1}{5}[/tex]
Ethan's function has a slope of m = 1/5
Therefore;
Marty's slope of 1/3 is larger, given that 1/3 > 1/5.

Which describes the graph of y=-(x + 5)2 + 3?
A. Minimum at (-5,3)
B. Maximum at (5,3)
C. Minimum at (5,3)
D. Maximum at (-5,3)
Answer:
D
Step-by-step explanation:
Since there is a negative sign, the graph is a n shaped quadratic curve and hence, there can only be maximum point. Hence we can eliminate A and C.
For a curve in the completing the square form y = (x+a)²+b, the turning points are (-a,b). Hence in this case, turning point is at (-5, 3).
Hence the correct option is D
Answer:
D

Answer:
[tex]\huge\boxed{Answer\hookleftarrow}[/tex]
Take the 1st equation & solve it :-

Now, take the second equation :-
[tex]3x = 8[/tex]
[You can't further solve this equation]
So, from the 2 solved equations we can see that,

Becky says that when she simplifies the following expression, the value is 6 less than her age. What is Becky's age? (7+11) - 8÷2 *
20
14
26
11
Answer:
Becky's age is equal to 20.
Step-by-step explanation:
The given expression is :
(7+11)-(8÷2)
Using Bodmas rule to solve it furthur,
(18)-4 = 14
According to the given condition, let the age is A.
The value is 6 less than her age,
14 = A-6
or
14+6 = A
A = 20
Hence, Becky's age is equal to 20.

Hey im confused on how to solve this. Can Anyone help me?
Answer:
The minimum unit cost is $9374.
Step-by-step explanation:
The unit cost C for making x engines is given by the quadratic function:
[tex]C(x)=0.3x^2-162x+31244[/tex]
We want to determine the minimum unit cost.
Since this is a quadratic function with a positive leading coefficient, the minimum value will be its vertex. The vertex of a quadratic can be found using the following formulas:
[tex]\displaystyle \text{Vertex}=\left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]
In this case, a = 0.3, b = -162, and c = 31244.
Find the x-coordinate of the vertex:
[tex]\displaystyle x=-\frac{(-162)}{2(0.3)}=\frac{162}{0.6}=270[/tex]
In other words, in order to achieve the minimum cost, only 270 engines must be made.
Then to find the minimum cost, substitute the value back into the function. So:
[tex]C(270)=0.3(270)^2-162(270)+31244=\$ 9374[/tex]
The minimum unit cost is $9374.

For exercises 5-6, suppose you are making a scale drawing. Find the length of each object on the scale drawing with the given scale. 5) A parking lot 460 meters wide; 1 centimeter = 16.5 meters. 6) A desk 7.5 feet long; 1.5 inches = 0.5 feet.
Answer:
8 88 cm
5.625 inches
Step-by-step explanation:
The length scale drawing of the given object :
5) A parking lot 460 meters wide;
1 centimeter = 16.5 meters.
1 cm on the drawing is equivalent to 16.5 m on ground
Hence, using cross multiplication :
If :
1 cm = 16.5 m
x = 460 m
Cross multiply :
16.5x = 460 * 1
x = 460 / 16.5
x = 8.88 cm
6) A desk 7.5 feet long; .
Scale = 1.5 inches = 0.5 feet
1.5 inches on map is equivalent to 0.5 feets on ground
1.5 inch = 0.5ft
x in = 7.5 feets
Using cross multiplication
0.5x = 1.5 * 7.5
0.5x = 11.25
x = 11.25 / 0.5
x = 5.625 inches

Aura took three biology exams and has an average score of 87. Her second exam score was 11 points better than her first, and her third exam score was 5 points better than her second exam. What were her three exam scores?
Answer:
Her first exam score was a 78, her second exam score was a 89, and his third exam score was a 94.
Step-by-step explanation:
Use the formula for the mean: sum of elements / number of elements
Let x represent her first exam score.
Her second exam score can be represented by x + 11, since it was 11 points better than her first.
Her third exam score can be represented by (x + 11) + 5, since it was 5 points better than her second.
Plug in all of these expressions into the mean formula. Plug in 87 as the mean, and plug in 3 as the number of elements (since there are 3 scores):
mean = sum of elements / number of elements
87 = ( (x) + (x + 11) + (x + 11) + 5 ) / 3
Add like terms and solve for x:
87 = (3x + 27) / 3
261 = 3x + 27
234 = 3x
78 = x
So, her first score was a 78.
Find her second score by adding 11 to this:
78 + 11 = 89
Find her third score by adding 5 to the second score:
89 + 5 = 94
Her first exam score was a 78, her second exam score was a 89, and his third exam score was a 94.
Two numbers have prime factorizations of 2^2 x 3^2 x 5 and 2 x 3 x 5. Which expression can be used to find their least common multiple
Answer: 2^2 x 3^2 x 5
You can use a star symbol * in place of the x symbols.
==================================================
Explanation:
We simply circle the primes where they have the largest exponent.
The unique primes listed here are: 2, 3, 5
The prime 2 has the highest exponent of 2, meaning 2^2 is part of the answer.The prime 3 has the highest exponent of 2, meaning 3^2 is also part of the LCMThe prime 5, without any exponent, is also part of the LCM. We can write this as 5^1 or just leave it as 5.Each question Sandra answers incorrectly changes her overall score by - points. Sandra's

a. 16 students
b. 40 students
c. 80 students
d. 106 students
Answer:
in the survey, 16 out of 80 students who where asked favored chicken nuggets.
so we need to calculate like this:
530 * 16/80
=530 * 1/5
=530/5
=106

One number is 8 times as large as another. Their difference is 21. What is the larger number?
Explanation:
x = smaller number
8x = larger number, since it's 8 times larger than the smaller
8x-x = 7x = difference of the numbers
That difference is 21, so we can say 7x = 21 which solves to x = 3
The smaller number is 3 and the larger is 8x = 8*3 = 24
As a check: 24-3 = 21, which confirms the answer.

This is incorrect as 1/8 plus 3/5 is 29/40
Step-by-step explanation:
:)
Answer:
Susan is incorrect.
Step-by-step explanation:
First, what we do is add 1/8 + 3/5
Our result will be 4/13 because 1+3 = 4 would be as the numerator, and 8+5 = 13 would be as the denominator.
We can't simplify 4/13.
If we did increase the number, however, it would be 8/26, which is not close to the answer.
Therefore, Susan is incorrect.

The Chang family is on their way home from a cross-country road trip. During the trip, the function D (t) = 3260 - 55t can be used to model
their distance, in miles, from home after t hours of driving.
part a:find D(12) and interpret the meaning in the context of the problem. part b: if D(t) =2490, find the value of t and interpret its meaning in the context of the problem
Answer:
See below.
Step-by-step explanation:
D(t) = 3260 - 55t
The function that shows their distance from home as a function of time shows that they started 3260 miles from home and are driving at 55 miles per hour.
part a:
D(12) = 3260 55(12)
D(12) = 3260 - 660
D(12) = 2600
Interpretation: After 12 hours of driving home, they are 2600 miles from home.
part b:
D(t) = 2490
3260 - 55t = 2490
-55t = -770
t = 14
Interpretation: When they are 2490 miles from home, they have driven for 14 hours.
