. Is (4,-3) a solution to the following system of equations?
X - y = 4
2x + y = 5
(Use elimination method)
Answers
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) :)

Two researchers are studying the decline of orangutan populations. In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. After how many years will the two populations be the same?
The two populations will be the same after
years.
Answers
Answer:
3 years
Step-by-step explanation:
Let y = number of orangutans, and let x = number of years.
For each study, the population, y, after x years is:
First study:
y = 784 - 25x
Second study:
y = 817 - 36x
We set the populations equal and solve for x, the number of years.
784 - 25x = 817 - 36x
Add 36x to both sides. Subtract 784 from both sides.
11x = 33
Divide both sides by 11.
x = 3
Answer: 3 years

Two lines are intersecting. What is the value of x? Enter your answer in the box. Two straight lines intersecting each other where the consecutive angles formed are x plus twenty three degrees and two x plus four degrees.
Answers
Answer:
x = 51
Step-by-step explanation:
Supplementary angles total 180º
(2x + 4) + (x + 23) = 180
Combine like terms
3x + 27 = 180
Subtract 27 from both sides
3x = 153
Divide both sides by 3
x = 51
Answer:
Hello! x = 51
Step-by-step explanation:
OMG I CAN ANSWER FINALLY!
it is forming a supplementary angle meaning it will add up to 180 degrees
51 × 2 = 102 102 + 4 = 106
51 + 23 = 74
106 + 74 = 180 therefore x = 51 Hope that helps.

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.

A silo has a diameter of 50 feet and a height of 30 feet with a cone on top adding another 10 feet of height. What is the volume of the silo.
Answers
Answer:
Step-by-step explanation:
Solve this by adding the volume of the cylinder with the volume of the cone. The volume of a cylinder is found from the equation:
pi * r^2 * h
In this case that gives pi * 50^2 * 30 = 75000pi
The area of the cone is found from the equation:
pi * r^2 * h *1/3
In this case you get pi * 50^2 * 10 * 1/3= 8333.pi
Add the two to ger 83333.333*pi ~261799

Between which two integers does -√46 appear on the number line please write in words
Answers
==========================================================
Explanation:
List out the perfect squares
1^2 = 12^2 = 43^3 = 94^2 = 165^2 = 256^2 = 367^2 = 498^2 = 64and so on. We can see that 46 is between 6^2 = 36 and 7^2 = 49.
We can say 6^2 < 46 < 7^2
Applying the square root to all three sides leads us to 6 < sqrt(46) < 7
Now multiply all three sides by -1. This will flip the inequality signs
We go from
6 < sqrt(46) < 7
to
-6 > -sqrt(46) > -7
It might help to order things from smallest to largest to get this
-7 < -sqrt(46) < -6
This means -sqrt(46) is between -7 and -6 on the number line
See the diagram below.
Answer:
Step-by-step explanation:
First notice that -√46 lies between -√49 and -√36, that is, between
-7 and -6.
Here all three numbers are negative because they lie to the left of zero (0) on the number line.
