Step-by-step explanation:
Given the system of equations:

Isolate [tex]y[/tex] for [tex]y-2x=-6[/tex], [tex]y=-6+2x[/tex]
[tex]\mathrm{Subsititute\:}y=-6+2x[/tex]
[tex]\begin{bmatrix}-6+2x-4x=0\end{bmatrix}[/tex]
[tex]\begin{bmatrix}-6-2x=0\end{bmatrix}[/tex]
Isolate x for [tex]-6-2x=0[/tex], [tex]x=-3[/tex]
[tex]\mathrm{For\:}y=-6+2x[/tex]
[tex]\mathrm{Subsititute\:}x=-3[/tex]
[tex]y=-6+2\left(-3\right)[/tex]
[tex]y=-12[/tex]
Therefore, the solution of the system of equations will be:

Step-by-step explanation:
One third of the people at a banquet ordered ice cream for desert. The rest ordered pie. One fourth of those requesting pie ordered apple pie. Of 180 people attended the banquet, how many ordered apple pie?
Answer:
30 people ordered the apply pie
Step-by-step explanation:
Given
Total number of people = 180
It is given that one -third of the people order the ice cream
So the people who order ice cream are:
[tex]= \frac{1}{3} * 180\\= 60[/tex]
60 people order ice cream and rest who ordered pie are:
= 180-60 = 120
Now it is given that one-fourth of the people who ordered pie ordered apple pie
So,
[tex]= \frac{1}{4} * 120\\= 30[/tex]
Hence,
30 people ordered the apply pie

For 6 days Bella drank 2/3 cups of orange juice
How much orange juice did she drink
HELP WILL GIVE BRAINLYIST
Answer:
She has drunk 66.67% of cups of juice in 6 days.
Step-by-step explanation:
Bella drank 2/3 cups of orange juice in 6 days.
It means that if there are 'x' number of cups, then she has drunk [tex]\frac{2}{3}x[/tex] of orange juice.
In other words, she has drunk 66.67% of cups.
For example, if the total number of cups = x = 9
Then she has drunk:
2/3 × 9 = 6 cups in 6 days.
Therefore, we conclude that for 6 days, she has drunk [tex]\frac{2}{3}x[/tex] of orange juice if there are 'x' number of cups.
Thus, she has drunk 66.67% of cups of juice in 6 days.

Let f(x) represent the weight of the jar when there are x marbles, where f(0)=10. Which equation correctly represents f(x) in terms of f(x−1) for all x>0?
A
f(x)=3⋅f(x−1)
B
f(x)=f(x−1)+3
C
f(x)=f(x−1)+3x
D
f(x)=f(x−1)+2x+1
Answer:
B
Step-by-step explanation:
We essentially have the sequence:
10, 13, 16, 19, 22,25...
This is an arithmetic sequence because each subsequent term differs only by a constant.
And this constant, the common difference, is +3 since each subsequent term is 3 more than the previous term.
Hence, we can write a recursive formula for our sequence.
We will first define our first term. The first term, at x=0, is 10. Hence:
[tex]f(0)=10[/tex]
Each term, x, is +3 the previous term (x-1). Therefore:
[tex]f(x)=f(x-1)+3[/tex]
Hence, our answer is B.
Answer:
B
Step-by-step explanation:
f(x)=f(x-1)+3x

Answer:
There are 0.5 ounces in 14 grams.
Step-by-step explanation:
Ounce is a larger unit while gram is a smaller unit. When we have to convert from a smaller unit to a larger unit, division is used.
It is also given that
1 ounce = 28 grams
In order to find the number of ounces in 14 grams, it will be divided by 28 grams
So,
[tex]14\ grams = \frac{14}{28} = 0.5\ ounces[/tex]
Hence,
There are 0.5 ounces in 14 grams.

COMPLETE THE TABLE PICTURED: A robot is put into a maze, it can only go N, E, S, and West. The value i represents the north, and the magnitude is equal to 1. I have figured out that N= i, East= 1, South= -i, and West= -1. When programming the robot, let the complex number d represent the direction the robot is facing. As the robot changes direction, the value of d will also change; so, the value of d is dependent on where the robot is in the maze. When the robot makes a turn, it would be useful to have an operation to perform on d to represent this turn. This is because after making a turn, the new value of d will depend on the old value of d. Complete the table for the new values of d if the robot is turning left or right. Then determine an expression in terms of d that will give the new position if the robot turns left and another expression if the robot turns right. Type these expressions in the last row of the table.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
A right turn represents a clockwise rotation of the direction vector by 90°. It is equivalent to multiplying the complex number representation by -i.
A left turn represents a counterclockwise rotation of the direction vector by 90°. It is equivalent to multiplying the complex number representation by i.
The attached table shows the desired values and expressions.
Step-by-step explanation:
[tex]\boxed{\begin{array}{c|c|c} \underline{Intial -d} & \underline {Left-turn} & \underline{Right-turn} \\ -1 & -i & i \\ 1 & i & -i \\ i & -1 & 1\\ -i & 1 & -1 \\ d & di & -di \end{array}}[/tex]

Sorry if im wrong have a good day :) :) :)
Answer:
8
Step-by-step explanation:
I think it's 8. When x=0, f(x) is at 1. When x=2, f(x) is at 9 i think ( the picture makes it difficult to confirm that for sure) so the average rate increase should be 8... since 1+ 8=9. Hopefully this is correct...

solve x^2+ 17x-12=-84
Answer:
(X+9)(X+8)=0
X=-9,-8
Step-by-step explanation:
x^2+ 17x-12=-84
x^2+17x-12+84=0
x^2+17x+72=0
x^2+(9+8)X+72=0
x^2+9x+8x+72=0
X(X+9)+8(X+9)=0
(X+9)(X+8)=0
X=-9,-8
So the value of the X is -9,-8
During the winter of 2012-2013, Buffalo, New York received 22 inches of snow in 12 hours. Oswego, New York received 31 inches of snow over a 15-hour period. What was Oswego’s snowfall rate ? Round your answer to the nearest hundredth.
Oswego’s snowfall rate given the inches of snow and the hours of snow is 2.07 inches / hour.
What is Oswego’s snowfall rate ?The rate of snowfall measures how fast snow was falling with respect to time. It is the ratio of the snow and time. The rate can be determined by dividing the total inches of snow by the total time.
Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.
Oswego’s snowfall rate = inches of snow fall / time
31 / 15 = 2.07 inches / hour

If the graph of the function f has a multiple zero at x = 2, what is a possible exponent of the factor x - 2? Justify your reasoning.
Answer:
[tex](x-2)^2[/tex]
The exponent is 2.
Step-by-step explanation:
Remember multiplicity rules:
If a factor has an odd multiplicity (e.g. it is raised to 1, 3, 5...) then it will cross the x-axis. If a factor has an even multiplicity (e.g. it is raised to 2, 4, 6...) then it will bounce off the x-axis.At x=2, we have the factor (x-2).
From the graph, we can see that the graph bounces off at that point.
Hence, the multiplicity of (x-2) must be even.
Therefore, a possible exponent for the factor (x-2) is 2. Any even number will suffice.
