pls explain why and how the answer u got is proportional
Answer:
A
Step-by-step explanation:
This is because to find out if a table is proportional you have to do y divided by x. Whatever table has the same answer on all of the table sections when you divide y by x, that is proportional.

An angle on a straight line is 180 degrees
⇒ this angel is made up of two angles with measures
⇒ 'x-7' and '57'
⇒ when these two angles are added up they are equal to the larger
angle that is 180 degrees in measure
Let's set up a mathematical equation based on the information and deduction:

Can two obtuse angles be supplementary? Why or why not?
Answer:
No.
Step-by-step explanation:
Two Angles are Supplementary when they add up to 180.
Let us consider the least obtuse angle, i.e., >90
Say 91 and add it to itself.
91+91 =182
This is >180
Hence, two obtuse angles can never be supplementary.

During geometry class, students are told that δtsr ≅ δusv. marcus states that δtsr is mapped to δusv by performing a rotation about point s. sam states that δtsr is mapped to δusv by a reflection across the line that goes through point s. determine if either student is correct. marcus is correct. sam is correct. both students are correct. neither student is correct.
Transformation involves changing the position of a shape through translation, dilation, rotation and reflection.Marcus's claim is correct.
What is transformation?A process by which one figure, expression, or function is converted into another one of similar value.
The triangles are given as: ΔTSR and ΔUSV
By comparison, we can see that point S is on both triangles, and this point on both triangles corresponds.
So, to map ΔTSR to ΔUSV, then ΔTSR must be rotated about point S to ΔUSV or rotate ΔUSV about point S to ΔTSR.
Hence, Marcus is correct, and Sam is not.

0.004 as a fraction is 1/250
one over two hundred and fifty
Answer:
one over Two hundred and fifty
Step-by-step explanation:
As we can see the 4 is 2 zeros away from the decimal point. This means that 4 must be in the thousandths place.
Therefore our answer is four thousandths.
Remember that we it is behind the decimal point, it becomes ths at the end.
To change this into a fraction we should get 4/1000 by taking the words literally.
Dividing both sides by 4 gives us 1/250
1/250 in words is one over Two hundred and fifty

how would I rewrite, 7x - 14y= -56 into slope-intercept form?
Answer:
[tex]y =\dfrac{1}{2}x+4[/tex]
Step-by-step explanation:
Slope-intercept form: y =mx +b
7x - 14y = -56
Step1 : subtract 7x from both sides
[tex]-14y = -7x - 56[/tex]
Step2: now divide both sides by (-14)
[tex]y =\dfrac{-7}{-14}x -\dfrac{56}{-14}\\\\y = \dfrac{1}{2}x+ 4[/tex]
Answer:
y = [tex]\frac{1}{2}[/tex] x + 4
Step-by-step explanation:
7x - 14y = - 56 ( subtract 7x from both sides )
- 14y = - 7x - 56 ( divide through by - 14 )
y = [tex]\frac{-7}{-14}[/tex] x - [tex]\frac{56}{-14}[/tex]
y = [tex]\frac{1}{2}[/tex] x + 4 ← in slope- intercept form

A) Convert the exponential function, 12^3=x^4 y^3 z^6, to its corresponding logarithmic function.
B) Write the log form from Part A into the expanded log form. **expression must be fully expanded for full credit**
The logarithmic function is ㏒ 12³ = ㏒ x⁴ · y³ · z⁶. The equation into the expanded logarithmic form is 3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z.
How to apply logarithms on a exponential function
Logarithms are the reciprocal of exponential functions. In this question we must apply logarithms and its properties to obtain a linear-like expression in the following lines. The logarithm properties are summarized below:
㏒ₐ (b/c) = ㏒ₐ b - ㏒ₐ c (1)
㏒ₐ (b · c) = ㏒ₐ b + ㏒ₐ c (2)
㏒ₐ bⁿ = n · ㏒ₐ b (3)
a) To obtain the corresponding logarithmic function we apply logarithms on both sides of the expression:
㏒ 12³ = ㏒ x⁴ · y³ · z⁶ (4)
The logarithmic function is ㏒ 12³ = ㏒ x⁴ · y³ · z⁶. [tex]\blacksquare[/tex]
b) The expanded logaritmic form of (4) consists in the addition and subtraction of logarithms of non-power numbers, whose formed could be found, if possible, by logarithm properties:
㏒ 12³ = ㏒ x⁴ · y³ · z⁶
㏒ 12³ = ㏒ x⁴ + ㏒ y³ + ㏒ z⁶
3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z
The equation into the expanded logarithmic form is 3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z. [tex]\blacksquare[/tex]
