Answer:
8
Step-by-step explanation:
If you replace x with the given answers, the only one that would make both answers the same is 8
Answer:
8
Step-by-step explanation:
7x - 4 = 5x + 12
7x - 5x - 4 = 5x - 5x + 12
2x - 4 = 12
2x - 4 + 4 = 12 + 4
2x = 16
2x/2 = 16/2
x = 8
how many solutions does 6x−y=−1 6x+y=−1
Answer:
x=−1/6 and y=0
Step-by-step explanation:
Answer:
There is one solution.
Step-by-step explanation:
x = - 1/6
y = 0
It can be solved simultaneously
6x - y = -1
6x + y = -1
Subtract equation two from equation one
-2y = 0
Divide both sides by-2
y = 0/-2
y = 0
Substitute 0 for y in either of the equations to get x
6x - 0 = -1
6x = -1
Divide both sides by 6
x = -1/6

If ZBPD and ZDPC have a sum of 72°. What is ZAPC?
A. 180.
B.90.
C.180.
D.18.
Hey there!
I don't know if it's too late, but oh well: The answer is 108°
Knowing that supplementary angles add up to 180°, and we also know that we have 2 out of 3 of the angle measures, so we can subtract that from 180:
180 - 72 =108°
Have a terrificly amazing day!
Answer:
∡APC = 108°
Step-by-step explanation:
∡ APB = 180°
∡ DPB + ∡ CPB + ∡APC = 180°
∡ BPD and ∡DPC have a sum of 72°
then:
72° + ∡APC = 180°
∡APC = 180° - 72°
∡APC = 108°

Answer:
X = 36/17
y = -8/17
Step-by-step explanation:
Since they both equal y, you could use them equal to each other.
(5/2)x-4=(-1/3)x+2
Then solve for x by combining like terms. X should be 36/17. Plug in x to find y in one of the equations. I will use the top one. (5/3)(36/17)-4=y. That should simplify down to (60/17)-4=y. Y would finally equal -(8/17).

Does anyone know how to do this?? Help please!!!!
Answer:
When we have a rational function like:
[tex]r(x) = \frac{x + 1}{x^2 + 3}[/tex]
The domain will be the set of all real numbers, such that the denominator is different than zero.
So the first step is to find the values of x such that the denominator (x^2 + 3) is equal to zero.
Then we need to solve:
x^2 + 3 = 0
x^2 = -3
x = √(-3)
This is the square root of a negative number, then this is a complex number.
This means that there is no real number such that x^2 + 3 is equal to zero, then if x can only be a real number, we will never have the denominator equal to zero, so the domain will be the set of all real numbers.
D: x ∈ R.
b) we want to find two different numbers x such that:
r(x) = 1/4
Then we need to solve:
[tex]\frac{1}{4} = \frac{x + 1}{x^2 + 3}[/tex]
We can multiply both sides by (x^2 + 3)
[tex]\frac{1}{4}*(x^2 + 3) = \frac{x + 1}{x^2 + 3}*(x^2 + 3)[/tex]
[tex]\frac{x^2 + 3}{4} = x + 1[/tex]
Now we can multiply both sides by 4:
[tex]\frac{x^2 + 3}{4}*4 = (x + 1)*4[/tex]
[tex]x^2 + 3 = 4*x + 4[/tex]
Now we only need to solve the quadratic equation:
x^2 + 3 - 4*x - 4 = 0
x^2 - 4*x - 1 = 0
We can use the Bhaskara's formula to solve this, remember that for an equation like:
a*x^2 + b*x + c = 0
the solutions are:
[tex]x = \frac{-b +- \sqrt{b^2 - 4*a*c} }{2*a}[/tex]
here we have:
a = 1
b = -4
c = -1
Then in this case the solutions are:
[tex]x = \frac{-(-4) +- \sqrt{(-4)^2 - 4*1*(-1)} }{2*(1)} = \frac{4 +- 4.47}{2}[/tex]
x = (4 + 4.47)/2 = 4.235
x = (4 - 4.47)/2 = -0.235

imagine you're in a queue to the airport check-in desk if two-thirds of the queue is in front of you and three tenths of the queue is behind you how many people are in the queue
Step-by-step explanation:
Let x be the number of people in the queue, including yourself.
We have 2/3 x + 1 + 3/10 x = x.
=> 29/30 x + 1 = x
=> x/30 = 1
=> x = 30.
Hence there are 30 people in the queue.

Find the midpoint of the line segment whose endpoints are (-2, 5) and (6, -9).
(2, -2)
(1, -4)
(4, -4)
Answer:
The midpoint of the line segment whose endpoints are (-2, 5) and (6, -9) is: (2,-2)
Step-by-step explanation:
Given two points are:
(-2, 5) and (6, -9)
The mid-point is the point that divides a line segment in two equal parts.
Let M be the mid-point then
[tex]M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
Let
(x1,y1) = (-2, 5)
(x2,y2) = (6, -9)
Putting the values in the formula, we get
[tex]M(x,y) = (\frac{-2+6}{2}, \frac{5-9}{2})\\M(x,y) = (\frac{4}{2}, \frac{-4}{2})\\= (2,-2)[/tex]
Hence,
The midpoint of the line segment whose endpoints are (-2, 5) and (6, -9) is: (2,-2)
