Answer:
D. a = 9, b = 21Step-by-step explanation:
Given the equation
ax + b = 9x + 21For the equation to have infinitely many solutions, both sides of the equation should be same.
a = 9 and b = 21 will make both sides equalCorrect option is D

Oy - 16 = S(x - 2)
Oy - 16 = 3x - 2
3- 16 = S(x - 2)
The relationship is non-linear
Given:
Table of values.
To find:
The equation in point slope form.
Solution:
From the given table it is clear that, the relationship is linear because the rate of change is constant because if x-value increases by 2 then y-values increases by 16.
Consider any two points from the table, i.e., (2,16) and (4,32).
[tex]Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]Slope=\dfrac{32-16}{4-2}[/tex]
[tex]Slope=\dfrac{16}{2}[/tex]
[tex]Slope=8[/tex]
The point is (2,16) and the slope is 8, so the point slope form is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-16=8(x-2)[/tex]
Therefore, the relationship is linear and point slope form is [tex]y-16=8(x-2)[/tex].
Answer:
y - 16 = 8(x - 2)

√30/5 is the right answer.Each person in a group of twenty people at a hotel orders one meal chosen from oatmeal, eggs, or pancakes and one hot beverage chosen from coffee or tea. One person will be selected at random from the twenty people. What is the sample space for the meal and beverage for the person selected
Answer:
[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]
Step-by-step explanation:
Given
[tex]Meal = \{Oatmeal, Eggs, Pancakes\}[/tex]
[tex]Beverage = \{Coffee, Tea\}[/tex]
Required
Determine the sample space
The sample space is a list of combination of 1 meal and 1 beverage.
Because one individual can order only one of the meals and one of the beverages at any one time, then no two orders can be the same
The sample space (S) is as follows:
[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]

A rectangular prism and its dimensions are shown in the diagram.
What is the total surface area of this rectangular prism in square inches?
Answer:
SA=78.5
Step-by-step explanation:
Find the area to all visible sides. 4*2.5=10, 10*2 (because there is two of these shapes) is 20. 4.5*4=18, 18*2=36. Finally, 4.5*2.5=11.25, 11.25*2=22.5.
20+36+22.5=78.5
A sunflower grows at a rate of 4cm each day.

26/4= 6.5 days
Answer:
for 80cm
1 =4 cm
x=80cm
4 cmx=80 cm
4 cm. 4 cm
x=20 days
Step-by-step explanation:
1 is equal to 4cm
there x is equal to 80cm
cross multiply
then divid though by 4 because it has letter x
and finally you 20 days as your answer.

Kaitlyn's older brother borrowed money for school he took out a loan that charges 6% simple interest he will end up paying 720 and interest after 6 years how much is Kaitlyn's brother borrow for school?
please please help asap
Answer: 2000
Step-by-step explanation:
The following can be gotten from the question:
Principal = Unknown
Rate = 6%
Time = 6 years.
Interest = 720
Note that: Interest = PRT / 100
720 = (P × 6 × 6) / 100
720 = 36P / 100
720 × 100 = 36P
72000 = 36P
Principal = 72000 / 36
Principal = 2000
The amount that he borrowed is 2000.

Which phrase best describes the graph of a proportional relationship?
OA. a straight line passing through the origin
OB.
a straight line
Ос.
a curve
OD
not a straight line
Answer:
A straight line passing through the origin
Step-by-step explanation:
A proportional relationship will have a particular quantity being related to another
For example, the relationship might be inverse or direct
In this case, we can have a straight line graph that passes through the origin
A straight line graph that passes through the origin would show the proportional relationship as it has no slope whatsoever

Answer:
-108
Step-by-step explanation:
About the easiest way to do this for small values of n is to compute each of the terms using the given recurrence relation.
[tex]a_1=4\\\\a_2=-3a_1=-3(4)=-12\\\\a_3=-3a_2=-3(-12)=36\\\\a_4=-3a_3=-3(36)=-108\\\\\boxed{a_4=-108}[/tex]
_____
Alternate solution
You recognize that the recurrence relation describes a geometric sequence with a first term of 4 and a common ratio of -3. The n-th term of a geometric sequence is ...
[tex]a_n=a_1\cdot r^{n-1} \qquad\text{for first term $a_1$ and common ratio $r$}[/tex]
Then the 4th term will be ...
[tex]a_4=4\cdot(-3)^{4-1}=4\cdot(-27)=-108[/tex]
