Ayden’s school took a field trip. A total of 32 vehicles were needed for the trip. Some students took the bus, and some students car-pooled. There were 27 people on each bus and 3 people in each car. 408 people altogether attended the trip. How many buses and cars were needed for the trip?
Step-by-step explanation:
Let x be the number of buses for the trip.
Then (32 - x) is the number of cars for the trip.
We have 27x + 3(32 - x) = 408.
=> 27x + 96 - 3x = 408
=> 24x = 312
=> x = 13
Hence there are 13 buses and (32 - 13) = 19 cars.
Which equation represents a line which is parallel to the line y=-4x-8y=−4x−8?
Answer:
Step-by-step explanation:
y = -4x - 8
Any equation with an equal slope will be parallel to the line
Example: y = -4x or y = - 4x + 8
As long as the equation has a different y-intercept and equal slope it will be parallel!
An equation of a line that is parallel to y = -4x - 8 would be in the form:
y = -4x + b
What is the equation of a line?In mathematics, the equation of a line is a formula that describes the relationship between the x and y coordinates of the points on the line.
Two lines are parallel if they have the same slope. The equation of the line y = -4x - 8 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
From y = -4x - 8, we can see that the slope is -4. So, any line that is parallel to this line must also have a slope of -4.
Therefore, an equation of a line that is parallel to y = -4x - 8 would be in the form:
y = -4x + b
Where b is some constant value that determines the y-intercept of the line.

2y-6=x goes with 3rd one which is y=2x+6,
Answer:
1 >>4
2>>1
3>>3

Step-by-step explanation:
1 - 2y-6 =x then y=(1/2)x +3
2 - 3y = -6 -x then y = (1/3)x + 2
3 = (1/2)y = 3 +x then y = 2x + 6
4 - 2x + y = 3 then y = -2x + 3

systèmes d'équations suivants. Trouve ensuite sa solution
b) { y = -x + 1
y = -2x - 2
Answer:
Solving the equations we get: x = -3, y = 4
The solution set is: (-3,4)
Step-by-step explanation:
We need to solve the system of equation and find value of x and y
The system of equation given is:
[tex]y = -x + 1\\y = -2x - 2[/tex]
Let:
[tex]y = -x + 1--eq(1)\\y = -2x - 2--eq(2)[/tex]
We would use substitution method.
Put value of y from eq(1) into eq(2) and find value of x
[tex]Eq(2)\;is:\\y=-2x-2\\Put\:y=-x+1\\-x+1=-2x-2\\-x+2x=-2-1\\x=-3[/tex]
So, we get x = -3
Now, for finding value of y, put value of x = -3 into equation 1
[tex]y=-x+1\\Put\:x=-3\\y=-(-3)+1\\y=3+1\\y=4[/tex]
So, we get y=4
Solving the equations we get: x = -3, y = 4
The solution set is: (-3,4)

We want to find the equation of the parabola in vertex form.
The format for the vertex form is;
y = a(x - h) + k
Where (h, k) is the coordinate of the vertex.
Thus, let's transform 0 = y² - x - 4y + 3 into the vertex form
Let's rearrange to get;
x - 3 = y² - 4y
Let's use method of completing the square to get right hand side;
x - 3 = (y - 2)² - 4
Add 4 to both sides to get;
x - 3 + 4 = (y - 2)²
(x + 1) = (y - 2)²

You are choosing between two different cell phone plans. The first plan charges a rate of 23 cents per minute. The second plan charges a monthly fee of $49.95 plus 9 cents per minute. How many minutes would you have to use in a month in order for the second plan to be preferable?
Answer:
357 minutes
Step-by-step explanation:
I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges. I then divided the monthly cost of $49.95 by .14 to get 356.79... So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357). At 356 minutes the first plan would still be cheaper.

1.How much will it cost Roger at the first print shop?
2. How much will it cost Roger at the second print shop?
3. Which option is a better deal? How much will Roger save?
Please help!!!!:/
Answer:
3. I would say shop one because it's at a lower price. Although, it is up to you.
Step-by-step explanation:
Roger wants 400 copies; First print shop; $21.50 for first 200 copies + $10 for every 100 additional copies. Second print shop; $0.15 per copy + no deals on bulk
1. how much will cost roger at the first print shop?

Answer:
m = 0
Step-by-step explanation:
1/2(-1.4m+0.4)=m+0.2
We move all terms to the left:
1/2(-1.4m+0.4)-(m+0.2)=0
Domain of the equation: 2(-1.4m+0.4)!=0
m∈R
We get rid of parentheses
1/2(-1.4m+0.4)-m-0.2=0
We multiply all the terms by the denominator
-m*2(-1.4m+0.4)-(0.2)*2(-1.4m+0.4)+1=0
Wy multiply elements
-2m^2(--(0.2)*2(-1.4m+0.4)+1=0
We use the square of the difference formula
-2m^2(+(0.2)*2(-1.4m+0.4)+1=0
Myra combined the like terms in the algebraic expression correctly.
Which statement correctly describes what Myra did?
8x^2 + 7-2x^2 + x
•Myra combined 8 and -2 to equal 6x2 +x+7- O
•Myra combined 8 and 2 to equal 10x2 +%+7
•Myra combined 8 and 7 to equal 15x2 - 2x + X-
•Myra combined 8 and 1 to equal gx2 - 2x2 +7-
(edge2020).
The answer would be the first one, combining 8 and -2
This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)
If you combine these you will get 6x^2 [8+(-2)=6]
Answer:
Myra combined the like terms in the algebraic expression correctly. Which statement correctly describes what Myra did?
8 x squared + 7 minus 2 x squared + x
Myra combined 8 and Negative 2 to equal 6 x squared + x + 7.

Step-by-step explanation:
We have, linear systems
[tex]2x_1+3x_2-5x_3=b_1[/tex]
[tex]17x_1+2x_2+8x_3=b_2[/tex]
[tex]-x_1+x_2-5x_3=b_3[/tex]
[tex](a)[/tex] Find the echelon form of the augmented matrix.
Firstly we find the augmented matrix (A) of the given linear system
[tex]A=\left[\begin{matrix} 2&3&-5&b_1\\17&2&8&b_2\\-1&1&-5&b_3\end{matrix}\right][/tex]
Now find the echelon form
[tex]=\left[\begin{matrix} 2&3&-5&b_1\\0&\frac{47}{2} &\frac{101}{2} &b_2-\frac{17}{2}b_1 \\0&\frac{5}{2} &\frac{-15}{2} &b_3+\frac{b_1}{2} \end{matrix}\right]^{R_2\rightarrow \frac{17}{2}R_1, R_3\rightarrow R_3+\frac{1}{2}R_1 }[/tex]
[tex]=\left[\begin{matrix} 2&3&-5&b_1\\0&\frac{47}{2} &\frac{101}{2} &b_2-\frac{17}{2}b_1 \\0&0&\frac{-10}{3} &b_3-2\frac{b_1}{6} \end{matrix}\right]^{R_2\rightarrow R_3-\frac{5}{6}R_1 }[/tex]
[tex](b)[/tex] From above echelon form of augmented matrix system is consistent .
So, system has always a solution exist for every condition of [tex]b_1,b_2, b_3[/tex]
[tex](c)[/tex] Yes, If we take point [tex](0,1,1)[/tex] then system of linear equation has exist a solution.
[tex](d)[/tex] yes, if pick randomly [tex]b_1,b_2, b_3[/tex] then always exist a solution of given system of linear equation.

What is the missing number in the series?
1, 16, 81, __, 625, 1296
Answer:
256
Step-by-step explanation:
We are given the series
1, 16, 81, __, 625, 1296
The missing number in the sequence is the fourth term
From the above sequence, we know that
1, 4², 9² , __, 25² , 36²
Difference between first term = 4 - 1 = 3
9 - 4 = 5
x - 9 = 7
x = 9 + 7 = 16
Hence, the fourth term = 16²
= 256
