Answer:
x = 6
y = 2
Step-by-step explanation:
For both triangles to be congruent, their hypotenuse lengths and the corresponding length of the other leg must be equal to each other.
Thus:
x = y + 4 ---› Eqn. 1
x + 2 = 4y ----› Eqn. 2
Substitute x = (y + 4) into equation 2.
(y + 4) + 2 = 4y
y + 4 + 2 = 4y
y + 6 = 4y
y - 4y = -6
-3y = -6
y = 2
Substitute y = 2 into equation 1
x = y + 4 ---› eqn. 1
x = 2 + 4
x = 6

Which line has an x-intercept of 4?
4x+y=8
-4x + y= 8
2x+ 2y = -8
-2x+2y= -8
Answers
Answer:
-2x+2y=-8
-2x+2(0)=-8
-2x=-8
x=-8/-2
x=4
(4,0)
=======================================================
Explanation:
If we plug in y = 0 and solve for x, we'll get the x intercept.
Doing so for choice A has us get
4x+y = 8
4x+0 = 8
4x = 8
x = 8/4
x = 2
So the x intercept is 2. We can rule out choice A
Through similar steps, choice B has an x intercept of x = -2, so we can rule that out as well.
Choice C leads to x = -4, so that's not the answer either.
Choice D has an x intercept of x = 4 since,
-2x+2y = -8
-2(4)+2(0) = -8
-8+0 = -8
-8 = -8
So that confirms choice D is the answer.

Step-by-step explanation:
Solve x4 - 11x2 + 18 = 0.
Answers
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3

The correct matrix addition is (m -1) + (( -12) + 0) = 12 .
Option B is correct.
What is Matrix Addition?To add two or more matrices, the basic process is matrix addition. Matrix addition is only possible if the matrices are in the same order. By order, we mean that the matrices have the same number of rows and columns. As a result, we can add the matrices' appropriate elements. Matrix addition is not possible if the order is changed.
We will add the rows:
Addition of First row
n + (4 -7) = 18
Addition of Second row
(m -1) + (( -12) + 0) = 12
Addition of Third row
(s+ 18) + (-18 - 11)= -28

there are 12 students in a class who are preforming at the school concert . this represents 40% of the class how many students are in the class?
Answers
Answer:
There are 30 students in class
Step-by-step explanation:
Let x be the total number of students
Then according to the given statement,
40% of x is 12
this can be expressed mathematically as:
[tex]12 = 40\%\ of\ x\\12 = 0.40 * x[/tex]
we can simply use this equation to find the total number of students
[tex]12 = 0.40x[/tex]
Dividing both sides by 0.40
[tex]\frac{0.40x}{0.40} = \frac{12}{0.40}\\x = 30[/tex]
Hence,
There are 30 students in class
