Answer: (2,-3)
Step-by-step explanation:
To solve by elimination method, we need to choose which variable to eliminate. Let's eliminate y. We need to make sure that the y coefficients in both equations are equal. To do that, you multiply the first equation by 5 and the second by 9.
(11x + 9y = -5)5 [multiply entire equation by 5]
(7x + 5y = -1)9 [multiply entire equation by 9]
--------------------------------------------------------------------------------------------------------
55x+45y=-25
63x+45y=-9
Now that the y are both the same, we can eliminate y by subtracting both equations and solve.
-8x=-16 [divide both sides by -8]
x=2
Now that we have x=2, we can plug that in to any equation to find y.
7(2)+5y=-1 [multiply]
14+5y=-1 [subtract both sides by 14]
5y=-15 [divide both sides by 5]
y=-3
With the y-value, we know that the answer is (2,-3).

-5x*2=-6
5x^2=6
5x=square root of 6
x= square root of 6/5
Answer:
[tex]\frac{\sqrt{30}}{5}, -\frac{\sqrt{30}}{5}[/tex]
Step-by-step explanation:
We have the equation [tex]-5x^2 + 6 = 0[/tex]
Since we know that any number multiplied by 0 is 0, we can safely make the term [tex]0x[/tex] to add to this.
So our equation now is [tex]-5x^2 + 0x + 6[/tex]
We can now solve for this using the quadratic formula, which is [tex]\frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex].
b is the coefficient on the x term, a is the coefficient on the [tex]x^2[/tex] term, and c is the constant.
Let's substitute inside the equation, since we know [tex]a = -5[/tex], [tex]b = 0[/tex] and [tex]c = 6[/tex].
[tex]\frac{{ - 0 \pm \sqrt {0^2 - 4\cdot-5\cdot6} }}{{2\cdot-5}}}\\\\\frac{{ 0 \pm \sqrt {0 -( -120)} }}{{-10}}}\\\\\frac{{ 0 \pm \sqrt {120} }}{{-10}}}\\\\\frac{{\pm \sqrt {120} }}{{-10}}}\\\\[/tex]
[tex]\frac{\sqrt{30}}{5}, -\frac{\sqrt{30}}{5}[/tex]

Solve the inequality 2x ≥ 6
Answer:
I think the answer would be x = 3, 4, 5, 6 (Anything greater than 3)
The answer is: x ≥ 3
Step-by-step explanation:
I think this is the answer because:
1) Since the sign ≥ means equal to or less than, x has to equal 3 or greater.
2) This is because if x = 3 then, 2 x 3 equals to 6. 6 and 6 are equal. If x = 4 then, 2 x 4 would equal 8. 8 is greater than 6.
3) Since 2x has to be something equal to or greater than 6, x has to equal 3 or something greater than 3.
Hope this helps!
The solution of the inequality 2x ≥ 6 is greater than or equal to three.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The inequality is given as,
2x ≥ 6
Simplify the inequality, then the value of x will be
x ≥ 6/2
x ≥ 3
Thus, the value of the variable x is greater than or equal to three.

2(x - 4) + 2x = -6x – 2
Answer:
x= 0.6
Step-by-step explanation:
Answer:
[tex]x = \frac{3}{5}[/tex]
Step-by-step explanation:
Apply the distributed property to 2(x - 4). It should now look like this: 2x - 8Plug 2x - 8 in: 2x - 8 + 2x = -6x - 2Combine like terms on the left side, so it now looks like this: 4x - 8 = -6x - 2Combine like terms even further: 4x - -6x = 8 - 2Simplify: 4x + 6x = 6Start adding, so it now looks like this: 10x = 6Divide each side by 10 to cancel out the 10 next to x. It should now look like this: x = 3/5I hope this helps!

Hey there! I'm happy to help!
Angles A and B are alternate exterior angles: they are on the outside of the parallel lines and opposite sides of the transversal. This means that they are congruent. So, we can set up an equation.
6x-2=4x+48
We subtract 4x from both sides.
2x-2=48
We add 2 to both sides.
2x=50
Divide both sides by 2.
x=25.
Have a wonderful day! :D
Answer:
x = 25
∠A = 148
Step-by-step explanation:
opposite exterior angle ∠A = ∠B
where
∠A = 6x - 2°
∠B = 4x + 48°
6x - 2° = 4x + 48°
6x - 4x = 48° + 2°
2x = 50°
x = 50°/2
x = 25
plugin x into ∠A = 6x - 2°
∠A = 6(25) - 2°
∠A = 148

Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.

y = 5 + 1/2 x
x = 5 + 1/2 y
1/2 y = x - 5
y = 2x - 10
f^-1(x) = 2x - 10

In the triangle, find x, y, u, v
Answer:
x = 9y = 12u = 24v = 32Step-by-step explanation:
Each of the triangles is similar, so we have ...
3/5 = (3+x)/20
x = 20(3/5) -3
x = 9
__
4/5 = (4+y)/20
y = 20(4/5) -4
y = 12
__
3/5 = (3 + x + u)/60
u = 60(3/5) -3 -9
u = 24
__
4/5 = (4 +y +v)/60
v = 60(4/5) -4 -12
v = 32
Barnika bought 100 eggs for Rs. 900. Out
of them. 8 were broken. She sold the remaining eggs
at the rate of Rs. 10.50 each. Find the profit or loss
percent.
Step-by-step explanation:
cost of an egg= 900/100= Rs.9
Total cost = 100×9=Rs.900
when 8 eggs broken, the eggs remained to sell is 92(100-8)
Total sales = 10.50×92=Rs.966
profit = total cost-total sales
profit =966-900= Rs.66
profit percentage =profit/total sales×100%
66/966×100%=6.832%
