Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
4-7/3-(-1)
-3/4
Best of Luck!
Answer:
The slope is -3/4x.

your welcome
Answer:
3x + 2y + 5
Step-by-step explanation:
-3 - 5x - 5y + 8x + 7y + 8
(first, let's group the like terms)
= - 5x + 8x - 5y + 7y - 3 + 8
(now, add the numbers that do not have a variable, - 3 + 8)
= - 5x + 8x - 5y + 7y + 5
(add the elements you think are alike)
= 3x + 2y + 5
Help anyone can help me do this question,I will mark brainlest.
a)
n(A U B) = n(A) + n(B) - n(A inverseU B)
n(A U B)= 50 + 62 - 26 = 86
b)
n(P)=23
n(Q)=25
P follow Q
so the P is inside Q
that means the n(P U Q) equal to 25
have a great day

please help
Answer:
73degrees-10degrees=63 degrees
Answer: 73 + (-19) = x, x = 73-19 = 54 degrees
Step-by-step explanation: Normally this would be a subtraction equation, but if you're looking for addition you can fix that by adding a negative number- which is the same as subtraction. In this case, the times have nothing to do with the equation itself.
Find the determinant:
3 -7
4. 12
Answer: 64
Step-by-step explanation:
The value of the square determinant will be 64.
What is the determinant?The determinant is a numerical variable in mathematics that is a product of the elements of a square matrix. It describes some of the matrix's attributes as well as the continuous map described by the matrix.
The determinant is given below.
[tex]\rm D = \begin{vmatrix}3 & -7\\ 4 & 12\end{vmatrix}[/tex]
The value of the determinant is calculated as,
D = 3 x 12 - 4 x (-7)
D = 36 + 28
D = 64
The value of the square determinant will be 64.

Find the value of x and KL if K is between J and L.
1. JK = 6 x , KL = 3 x , and JL = 27
2. JK = 2 x , KL = x + 2, and JL = 5 x – 10
Answer:
Step-by-step explanation:
1) JK + KL = JL
6x + 3x = 27
9x = 27
x = 27/9
x = 3
2) JL = JK + KL
5x - 10 = 2x + x + 2 {Combine like terms}
5x - 10 = 3x + 2
Add 10 to both sides
5x = 3x + 2 + 10
5x = 3x + 12
Subtract 3x from both sides
5x - 3x = 12
2x = 12
Divide both sides by 2
x = 12/2
x = 6

Answer:
x=6
AD=x+18
=6+18
=24 (the final answer)
Answer:
x = 6
AD = 24
Step-by-step explanation:
To find the value of x and AD
We know that the opposite sides of parallelogram are equal
so
AD = BC
3x + 6 = x + 18
3x - x = 18 - 6
2x = 12
x = 12/2
x = 6
now we need to find AD
AD =3x + 6
instead of x we have to put 6
AD = 3 (6) +6
= 18 +6
= 24
AD = 24

Espero que te ayudeA and Z are both between points M and N such that MZ=AN and A is between M and Z. Given: MA=5x AZ=3x-2 AN=6(2x-1) find MN
Answer:
MN = 11
Step-by-step explanation:
M___A___Z___N
MZ =MA+AZ
MZ = 5x + 3x -2 = 8x - 2
MZ = AN
8x - 2 = 6(2x-1)
8x - 2 = 12x - 6
12x - 8x = 6 -2
4x = 4
x =4/4
x =1
MA= 5x = 5(1) = 5
AZ = 3x-2 = 3(1) - 2 = 3 -2= 1
MZ = 8x -2 = 8(1)-2= 8-2=6
AN = 12x - 6 = 12(1)-6 = 12 - 6 = 6
MN = MA + AN = 5 + 6 = 11

write 120 as product of powers of its prime factors.
Step-by-step explanation:
[tex]120=2^3 \times 3 \times 5[/tex]
Answer:
2³ × 3 × 5
Step-by-step explanation:
To find the prime factors, first divide 120 by 2 until finished , then 3 and so on
120 ÷ 2 = 60
60 ÷ 2 = 30
30 ÷ 2 = 15
15 ÷ 3 = 5
5 ÷ 5 = 1 ← finish when 1 is obtained
Then
120 = 2× 2 × 2 × 3 × 5 = 2³ × 3 × 5

Which list contains ONLY irrational numbers?
Three consecutive integers sum to 6. What is the least of these integers?
Answer:
The least of the three integers is 1.
Step-by-step explanation:
Hi there!
Let x be equal to the least of these integers.
Let x+1 and x+2 be the next consecutive integers.
We're given that these integers have a sum os 6.
We can use these to construct an equation:
[tex](x)+(x+1)+(x+2)=6[/tex]
Combine like terms:
[tex]x+x+1+x+2=6\\x+x+x+1+2=6\\3x+3=6\\3x=3\\x=1[/tex]
Therefore, the least of these integers is 1.
The other two integers would be 2 and 3.

Consider each equation. Find the value of m in each equation below. Justify your answer
Answer:
Part B: m = - 4
Part C: m=0
Step-by-step explanation:
Part B:
x^3 * y^2 * x^2 * y3 * z^m * z^5 = x^5 *y^5 * z
(1/z^-5= z^5)
x^3 * x^2 = x^5
y^2 * y^3 = y^5
z^m * z^5 = z
Z^-4 * z^5 = z
m = - 4
Part C:
m = 0 (any number to the power of 0 = 1)
