Answer:
x=8 y=4
Step-by-step explanation:
eliminate x: make x of two equation equal to each other
2(-3x+9y=12) : -6x+18y=24 ___[1]
-3(2x-8y=-16) : -6x+24y=48 ___[2]
[2]-[1]= 6y=24
y=4substitute y to any equation;
2x-8y=-16
2x-8(4)= -16
2x= -16+32
2x= 16
x=8Answer:
x=14 and y=6
Step-by-step explanation:
-3x+9y=12.............(i)×2
2x-8y=-16..............(ii)×3
Multiplying equation (i) by 2 and equation (ii) by 3 and adding (i) and (ii)
-6x+18y=12
6x-24y=-48
-----------------
0-6y=-36
or, -6y=-36
So,y=6
From (i)
-3x+9y=12
or,-3x+9×6=12
or,-3x+54=12
or,-3x=12-54
or,-3x=-42
So,x=14

Solve for x: 1/3(21-3x)=1/2(8-4x)
Answer:
x = -3
Step-by-step explanation:
[tex] \frac{1}{3} -(21 - 3x) = \frac{1}{2} (8 - 4x)[/tex]
[tex]21 - 3x = 3(4 - 2x)[/tex]
[tex]21 - 3 x = 12 - 6x[/tex]
[tex] - 3x + 6x = 12 - 21[/tex]

Please help: is the square root of -9 a whole number, integer, rational., or irrational?
Answer:
Step-by-step explanation:
None of the above.
It is a complex number. The sqrt(-9) is defined as 3i.
i is a definition brought into existence to represent the square root of -1. There is nothing at this level of math that you can point to and say this is the physical thing that is the square root (-1). It is just a math/physics definition.
a mans age today is four years less than five times the age of his oldest son. let a represent the son's age. write an expression to represent the man's age.
Answer:
m = 5s - 4
Step-by-step explanation:
Man = m
Son = s
the mans age is 4 years less than 5 times his sons age
5 times his sons age is 5s
4 less than that is 5s - 4
The man's age is 5s - 4 or m = 5s - 4

0 less than or equal to theta less than 2pi
sin theta= 1/2
HELP QUICK PLEASE !!!
WILL GIVE BRAINLIEST !
Answer:
theta = 4.5642792103077898247
Step-by-step explanation:
0 <= theta < 2Pi sin(theta) = 1/2
so
2Pi sin(theta) = 1/2
Pi sin(theta) = 1/4
sin(theta) = 1/(4Pi)
sin(theta) = .0795774715459
theta = arcsin(.0795774715459) = 4.5642792103077898247

Answer:
x = 18°
Step-by-step explanation:
∠AOB and ∠BOD form linear pair of angles, so they are supplementary, i.e., their sum is 180°.
130° + (2x + 14)° = 180°
=> 130° + 2x° + 14° = 180°
=> 2x° = 180° - 130° - 14°
=> 2x° = 36°
=> x = 36°/2°
=> x = 18°

Answer and Step-by-step explanation:
1-6
a.
What you can do is plug in 6 and start by doing the first machine first, then the second. If this doesn't work, do the second machine, then the first machine.
The order that works is second machine, then first machine.
Second Machine:
y = [tex](6)^{2} -6[/tex] = 36 - 6 = 30
Plug into first machine now.
First Machine:
y = [tex]\sqrt{(30) - 5} = \sqrt{25} = 5[/tex]
We see that the result is 5.
b. If we were to do the order of second machine, then first machine, we will never get a negative result (or -5 for that matter), due to the fact that you can't algebraically square root a negative number.
However, if we were to do the order of first machine, second machine, we can get a negative number. To get -5, we plug in 6 for x in the first machine, getting an answer of 1. We plug this into the second machine, getting 1^2 - 6, which results in -5.
1-7. The absolute value of a value is the positive version of that value.
a. |54| = 54
b. [tex]-|-7\frac{3}{5}|[/tex] = [tex]-7\frac{3}{5}[/tex]
c. |3| - |-1| = 3 - 1 = 2

b. The amount of squares on each side of the figure increases by 1.
c. There would be 1 square, because we know that the pattern is there is 2 squares added to the next figure, 1 at each end. If we go back a figure, we take away 2 squares.
1-9.
a. -42 - 17 = -59
b. 8 - (-9) = 8 + 9 = 17
c. 8(-9) = -72
d. -42 ÷ (-7) = 6
e. -2(-3)(-4) = 6(-4) = 24
f. -18 - 7 = -25
g. [tex](-5)^{2}[/tex] = 25
h. [tex]-5^{2} = -(5)^2 = -(25)[/tex] = -25
i. [tex]\sqrt{49}[/tex] = 7
1-10. x = 2 Plug 2 in for x, then solve.
a. y = 7 - 3(2) = 7 - 6 = 1
b. y = [tex](2)^2 -1[/tex] = 4 - 1 = 3
c. y = [tex]\frac{18}{2}[/tex] = 9

Which of the following fractions has the greatest value?
3/4
5/8
5/6
5/9
3/7
We can see that 420/504 is the largest value among the fractions. the fraction 5/6 has the greatest value.
To determine which fraction has the greatest value, we can compare the fractions by finding a common denominator and comparing the numerators.
Let's find a common denominator for all the fractions, which is the least common multiple (LCM) of the denominators.
The denominators are 4, 8, 6, 9, and 7.
The LCM of 4, 8, 6, 9, and 7 is 504.
Now, let's convert each fraction to have a denominator of 504:
3/4 = (3/4) * (126/126) = 378/504
5/8 = (5/8) * (63/63) = 315/504
5/6 = (5/6) * (84/84) = 420/504
5/9 = (5/9) * (56/56) = 280/504
3/7 = (3/7) * (72/72) = 216/504
Comparing the numerators, we can see that 420/504 is the largest value among the fractions.
Therefore, the fraction 5/6 has the greatest value.

Explanation:
Point C is located at (-6,3). The x coordinate is x = -6.
Going from x = -6 to x = -1 is 5 units to the right. We move another 5 units to the right to go from x = -1 to x = 4 when arriving at its reflected location (4,3). The y coordinate stays the same the entire time.
It might help to refer to the diagram below.
