simplify by dividing [ -3/-8] divided by 5/9 (5 points)
A. -15/-72
B. 15/72
C. -27/-40
D. 27/40
Answers
Answer: D
Step-by-step explanation:
(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.
I think C was supposed to be -27/40 so D is the correct answer since it's positive.

The sum of two numbers is 64 and the difference is 8. What are the numbers?

Step-by-step explanation:
Trust me its correct
pls mark me as brainliest
The addition is one of the four fundamental mathematical operations. The two of the given numbers are 36 and 28.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Let the sum of two numbers be represented by a and b.
Given that the sum of the two numbers is 64. Therefore, we can write,
a + b = 64
Also, it is given that the difference between the two numbers is 8, therefore, we can write,
a - b = 8
Adding the two of the equation formed together, then,
a + b + a - b = 64 + 8
2a = 72
a = 72/2
a = 36
Substitute the value of a in any one of the two equations,
a + b = 64
36 + b= 64
b = 64 - 36
b = 28
Hence, the two of the given numbers are 36 and 28.

2 X + 3 Y=_ 4
_ 5 x + 4 Y + 13 =0
Answers
X = -10
Y = 8
2 X + 3 Y = 4 ---- (i)
5 X + 4 Y + 13 = 0 ---- (ii)
rearranging eqn (ii), we have
5X + 4Y = -13 ----- (ii)
multiply eqn (i) by 5 and eqn (ii) by 2
10X + 15Y = 20 ---- (iii)
10X + 8Y = -26 ---- (iv)
subtracting eqn (iv) from (iii), we have
10X - 10X + 15Y - 8Y = 20 - (-26)
0 + 7Y = 20 + 26
7Y = 56
Y = 56/7
Y = 8
Substituting Y into eqn (i), we have
2X + 3Y = 4
2X + 3(8) = 4
2X + 24 = 4
2X = 4 - 24
2X = -20
X = -20/2

Second, make denominator the same by multiplying 4/3 by 2/2:
4/3 * 2/2 = 8/6

8/6 - 5/6 = 3/6
Fourth, simplify:
3/6 = 1/2
The correct answer for the difference between [tex]1\dfrac{1}{3}[/tex] and [tex]\dfrac{5}{6}[/tex] is [tex]\dfrac{1}{2}[/tex] .
Given expression:
[tex]1\dfrac{1}{3} - \dfrac{5}{6}[/tex]
convert [tex]1\dfrac{1}{3}[/tex] to an improper fraction:
[tex]1\dfrac{1}{3} = \dfrac{3*1 + 1}{3}[/tex]
= [tex]\dfrac{4}{3}[/tex]
Now, the expression becomes:
[tex]\dfrac{4}{3} - \dfrac{5}{6}[/tex]
To subtract these fractions,
The common denominator is 6.
Rewrite the fractions with the common denominator:
[tex]\dfrac{4}{3}*\dfrac{2}{2}[/tex]
= [tex]\dfrac{8}{6}[/tex]
The expression becomes:
[tex]\dfrac{8}{6} - \dfrac{5}{6}[/tex]
Subtract, the numerators while keeping the common denominator:
= [tex]\dfrac{8-5}{6}[/tex]
= [tex]\dfrac{3}{6}[/tex]
Divide numerator and denominator by greatest common factor (which is 3):
3 ÷ 3 = 1
6 ÷ 3 = 2
= [tex]\dfrac{1}{2}[/tex]
The correct answer is for [tex]1\dfrac{1}{3} - \dfrac{5}{6}[/tex] is [tex]\dfrac{1}{2}[/tex].

Step-by-step explanation:
The requried, expression for the translation of trapezoid ABCD to A'B'C'D' is (x, y) ⇒ (x - 3, y +1). Options A and D both are correct.
What is the transformation of geometry over the coordinate plane?Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.
Here,
Consider trapezoid ABCD,
As we can see the trapezoid is translated 3 units to the left and one unit up,
So the expression of the given translation is given as,
(x, y) ⇒ (x - 3, y +1)
To for the trapezoid A'B'C'D'.
Thus, the requried, expression for the translation of trapezoid ABCD to A'B'C'D' is (x, y) ⇒ (x - 3, y +1). Options A and D both are correct.

f(4) = -28
The value of f(4) for the function is -28
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given a function as f(x) = - 4(x + 3)
f(4) is another notation for x = 4
Therefore we just plug-in 4 for x

f(4) = -4((4)+3)
