Find the value of x and
y if x-y=3 and 2x+3y=4
Answers
Answer:
Step-by-step explanation:
Given :
x-y = 3 equation(i)
2x + 3y = 4 equation(ii)
Now,
x - y = 3
x = 3 + y
substitute the value of x in equation (ii)
2x + 3y = 4
2(3 + y) + 3y = 4
6 + 2y + 3y = 4
6 + 5y = 4
y = -2/5
2x+3y=4
Using elimination we can multiply the top equation by -2 to Eliminate the x values. Doing this gives us
-2(x-y)= -2(3)
Simplifying we have
-2x+2y=-6
And then adding the second equation, we can have a system of two equations where the x eliminates
-2x+2y=-6
+2x+3y=+4
Adding we get that
5y=-2
Dividing by 5 on both sides gives us y=-2/5
We can substitute this y term in for the first equation. Doing so we have
x-(-2/5)=3
using the a-(-b)=a+b rule we get
x+2/5=3
Thus x=3- 2/5
So using a calculator we can say that x=13/5.
Thus your answers are x=13/5 and y=-2/5

Answer:
-1/2048
Step-by-step explanation:
The Order of Operations tells you to evaluate each of the exponential expressions first. Then you do the division.
= (1/32) / (-64)
= -1/(32·64) = -1/2048
__
You can also rewrite the expression in terms of powers of 2.
2^-5/-4^3 = -1/((2^5)(2^2)^3) = -1/(2^5×2^6) = -1/2^11
= -1/2048
_____
The applicable rules of exponents are ...
a^-b = 1/a^b
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)

Step-by-step explanation:
The radius is half the diameter, so is 14/2 = 7.
The equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
The equation of the circle with center (-4, -3) and radius 7 is ...

When you square or cube a negative number is it still negative or does it become positive?
Example:
(-4)^{2}
Answers
(-4)^2 = (-4)ª(-4) = 16
When you cube a negative number, the result is negative.
(-4)^3 = (-4)•(-4)•(-4) = -64
Negatives pair up and cancel out, so odd exponents always have one negative unpaired, making the result negative.

Find the distance between the pair of points. Round your answer to the nearest tenth if necessary.
Answers
Answer:
The distance between the pair of points is 12.0 (to the nearest tenth)
Step-by-step explanation:
The distance between a pair of points in a coordinate system is found by the formula:
d =[tex]\sqrt({x_2-x_1)^2+(y_2-y_1)^2}[/tex]
where, the points are:
[tex](x_1,y_1)\ and\ (x_2,y_2)[/tex]
From the graph,
[tex](x_1,y_1)=(-6,-2)\\(x_2,y_2)=(2,7)[/tex]
Substitute the points into the formula:
[tex]d=\sqrt{(2-(-6)^2+(7-(-2)^2} \\d=\sqrt{(2+6)^2+(7+2)^2} \\d=\sqrt{8^2+9^2} \\d=\sqrt{64+81} \\d=\sqrt{145} \\\d=12.0[/tex]

Answer:
83 m
Step-by-step explanation:
The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...
8.26(10 m) = 82.6 m ≈ 83 m
_____
The distance formula will tell you the distances are ...
AC = √(3² +1²) = √10
BD = √(5² +1²) = √26
The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.
