Answer:
Step-by-step explanation:
I would say the first thing you should always do is graph the quadratic. See where the x intercepts are. If there aren't any, go onto step 2. If there are, make note of them. The quadratic formula will give you the same answer. You can use Desmos to graph the quadratic.The second thing to do is to test what is under the square root (called the discriminate). If you get something weird like the square root of a minus number, then the graph should have told you that the quadratic does not cross the x axis at all.When you have done those two things, you are ready to use the whole quadratic. Watch out for -b at the beginning. If b is - 4 (for example) the -b will make it 4Question 2 of 10 What is the slope of the line shown below? O A O B. O c. LOG O p. 3

Answer:

Step-by-step explanation:
go to the picture okay
Answer: 7
Step-by-step explanation:
2x(3x-5) -3(x-3)2(2)(3(2)-5) -3(2-3) First you substitute 2 for all the x's. The twos in . parentheses represent multiplication.4(6-5) -3(2-3) Second, you multiply 2 by 2, which equals 4, . and multiply 3 by 2, which equals 6. 4(1) -3(-1) Next, you solve the problems in the . parentheses, which is 6 minus 5 is 1, and 2 . minus 3 is -14-(-3) Next, you multiply 4 by 1, which is 4, and . multiply 3 by -1.4+3 Since two negatives make a positive, the . equation changes to 4 plus 3.7 Finally, you add 4 plus 3 and get 7.P.S: Sorry about the random periods. I had to put them in to format it like that.

. Is (4,-3) a solution to the following system of equations?
X - y = 4
2x + y = 5
(Use elimination method)
Answer:
No. The correct solution is (3,-1)
Step-by-step explanation:
Since we are using elimination method, we can go ahead and see that we can cancel "-y" from the first equation and "+y" from the second equation.
Once we do that, we go ahead add the like terms and get 3x = 9
Then, we divide by 3 on each side and get x = 3
Now, we can take that value of x and plugin to any of the original 2 equations we started with.
Say we plugin x = 3 into the second equation.. it will turn to, 2(3) + y = 5
Then we solve for y.
2(3) + y = 5
6 + y = 5
6 - 1 = 5
y = -1
There, we found our x value and our y value, (3,-1) :)
1. Find the median, mode, and mean for, {1, 4, 8, 3, 4, 5, 2, 2, 2, 5}
Answer:
Mean: 3.6
Median: 3.5
Mode: 2
Step-by-step explanation:
Mean: The sum of all numbers divided by the amount of numbers.
Median: The number in the middle.
Mode: the number that is frequently used.
------------------------------------------------------------------------------------------------------
Mean: 1 + 4 + 8 + 3 + 4 + 5 + 2 + 2 + 2 + 5 = 36 ÷ 10 = 3.6
Median: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. since two numbers are in the middle, we need to add 3 + 4 ÷ 2 = 3.5
Mode: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. The mode is two because it is used the most.

The length of the longer piece is 124/7.
What is algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
let the two pieces be x(longer) and y (shorter)
So,
x+y=31
and, 3x=4y
3x-4y=0
Solving both the equations:
x= 124/7 and y=93/7
Hence, the length of longer piece is 124/7.

Answer:
-5 = Contraction
-(1/4) = Contraction
3.5 = Expansion
(6/7) = Expansion
Step-by-step explanation:
Contraction means decreasing and expansion means increasing. So the numbers containing negative signs are contraction and the numbers containing positive signs are expansion.

Tao uses elimination to solve the following system of linear equations.
Given:
The system of equation is:
[tex]-2x+4y=16[/tex]
[tex]2x+2y=8[/tex]
To find:
The solution of the given system of equations.
Solution:
We have,
[tex]-2x+4y=16[/tex] ...(i)
[tex]2x+2y=8[/tex] ...(ii)
Add (i) and (ii) to eliminate the variable x.
[tex]6y=24[/tex]
[tex]y=\dfrac{24}{6}[/tex]
[tex]y=4[/tex]
Putting [tex]y=4[/tex] in (ii), we get
[tex]2x+2(4)=8[/tex]
[tex]2x+8=8[/tex]
[tex]2x=8-8[/tex]
[tex]2x=0[/tex]
Divide both sides by 2.
[tex]x=0[/tex]
Therefore, the solution of given system of equations is (0,4). Hence, the correct option is A.

5) Find the value of x
Answer:
x = 28
Step-by-step explanation:
the angle shown is a right angle
right angle = 90°
•°• (x + 6) + 56 = 90
=> x + 62 = 90
=> x = 90 - 62
=> x = 28Answer:
28
Step-by-step explanation:
5)
(x + 6)° + 56° = 90°
x + 6 + 56 = 90
x + 62 = 90
x = 90 - 62
x = 28
What will be the multipicative inverse of 6?
Answer:

Step-by-step explanation:
The multiplicative inverse of a number is that number as the denominator, and 1 as the numerator. Let's solve this problem using that knowledge.
6 × ? = 1
6 × m = 1
(m stands for multiplicative inverse)
m = 1/6

Cut the the shape into a right triangle and a rectangle
Tri: find measure of the base
sin(45)= opp/hyp
= x/1.8
1.8 *sin (45) = x
x = 1.3
base of tri = 1.3
Area of tri = 1/2bh
1/2(1.3)(1.3)
=0.845
Area of rectangle: 1.1*1.3=1.43
Total area = 1.43+0.845
=2.245
=2.3m^2

A jar contains 3 yellow and 7 green marbles. You randomly draw one marble from the jar then REPLACE it and randomly draw a second marble. Find the probability that you draw a yellow marble first and then a green marble.
3 yellow + 7 green = 10 total marbles.
The probability of picking a certain color is the number of that color over the total quantity.
Picking yellow would be 3 yellow / 10 total = 3/10
Picking green would be 7 green / 10 total = 7/10
To find the probability of doing both multiply the probability of each one by each other:
3/10 x 7/10 = 21/100
The answer would be 21/100
