2x + 3y = 2
Consider the system
3x + 3y = -6
Describe how to solve the system by multiplying the first equation by a constant and subtracting. Why
would this method be less than ideal?
(select) v the first equation by 1.5 and subtract. This would be less than ideal because you would
introduce (select) into the solution process.

Answer:
24) $230.45
Step-by-step explanation:
25%=25/100=0.25
0.25*357.35=89.38 (rounded to the nearest hundredth)
357.35-89.38=267.97
Now, we have the 25% discount, it is the same thing for the 14% discount.
14%=14/100=0.14
267.97*0.14=37.52(rounded to the nearest hundredth again)
267.97-37.52=230.45
Therefore, total cost is $230.45

Answer:
34
Step-by-step explanation:
Answer:
Step-by-step explanation: 180 bagels
The unit rate, in bagels per hour, is ---------------------- = 36 bagels/hour
5 hours
In 22 hours, the bakery can bake (36 bagels/hour)(22 hours) = 792 bagels

How might doing math slowly help with problems that are difficult to understand or hard to solve?
Q: How might doing math slowly help with problems that are difficult to understand or hard to solve?
A: It calms you down. When you are stressed, you are most likely to get it wrong because you are panicking. This also helps because you can read the problem correctly and make sure you are doing it right, because in math, If you get 1 small thing wrong, you usually get the entire thing wrong.
I hope this helped!

Calculate
√6x√20 divided by
√3
Give your answer in the form a√b where a and b are integers, and b is as small as
possible.
Answer:
(√6x√20) / √3 = 2√10
Step-by-step explanation:
hello :
(√6x√20) / √3 =√2x√3 x√4x√5 / √3
because : √6 = √2x√3 and √20= √4x√5 = 2x√5
now simplify by √3 :(√6x√20) / √3 =√2x2x√5
(√6x√20) / √3 = 2√10 so : a =2 and b =10

Mary wanted to solve the system of equations shown. She first used row reduction to get the system into 2 equations with 2 variables, x and y. She then used her calculator and got the graph shown. What is the solution to her system?
Answer: (2, -1, 3)
Step-by-step explanation:
The graph shows you that x=2 and y=-1 so, plug those values back into one of the equations to solve for z. You should get z=3 giving you a solution of (2, -1, 3).

Guide Questions:
1. How do you saive for the area of the shaded region in figure A?
2. How do you solve for the area of the shaded region in figure B?
3. Is method finding the shaded region in figure A and B the same? Why? or Why not?
please answer on 3 i need answers for that number 3 questions
Answer:
1. The area is found by using the formula for a rectangle
The area is 150 cm²
2. The area is found by the definite integral for the area between two points under a curve
3. The methods are different
The methods are different because the area of figure A is found by the multiplication between the dimensions, while the area of figure B is found by the difference between the values of the integral of the function between the points
Step-by-step explanation:
1. The area of the shaded figure A is found by multiplying the dimensions of the figure, which is the length multiplied by the breadth of the figure
From the question, we have;
The area of the rectangular figure, A = Length × Breadth
The length of the figure = 15 cm
The breadth of the rectangular figure = 10 cm
Therefore, we have;
A = 15 cm × 10 cm = 150 cm²
The area of the rectangular figure, A = 150 cm²
2. The bell shape of the figure B is obtained from a function f(x) as obtained from MIT mathematics website as follows;
[tex]f(x) = e^{-t^2}[/tex]
Therefore the area of the shaded region in the bell shaped figure between the points 0 and 1 on the x-axis is found by integration as follows;
[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt = \dfrac{1}{2} \cdot \sqrt{\pi} \times erf(t)[/tex]
Using a graphing calculator, we have;
[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt \approx 0.746824[/tex]
3. The method of finding the area of figure A is different from the method of finding the area of the figure B
The methods are different because the area of figure A is the area of the whole figure of a geometric shape with known formula for area while the area of of the shaded region has no predefined formula but is calculated using the calculus for the area under a curve.

Cu cat este mai mare suma numerelor 25 si 17 față de diferența lor? ( se vor folosi doua paranteze mici.)
Given :
Two numbers 25 and 17.
How much larger is the sum of the numbers 25 and 17 compared to their difference? (Two small brackets will be used.)
To Find :
How much larger is the sum of the given numbers as compared to their difference.
Solution :
Sum of given numbers, S = 25 + 17 = 42 .
Difference of given numbers, D = 25 - 17 = 8 .
The difference between S and D is, S - D = 42 - 8 = 34 .
Therefore, sum of the numbers is larger by 34 than in difference.

Answer:
DCB=33
Step-by-step explanation:
We are given the angle for a and we know the angle for ADC is 90 because AB & DC are perpendicular. Given two angles of a triangle we can find the third by subtracting the two known values from 180 because we know a triangle totals 180.
180-33-90=57
So we can also find CDB because we know AB & DC are perpendicular. It is also 90 because two perpendicular lines make a 90 angle.
DCB can be found because we know that ACB makes a 90 angle and the ACD portion is 57. So we subtract 57 from 90.
90-57=33
We can also find CBD by subtracting CDB and DCB from 180.
180-90-33=57
