Answer:
The independent variable is x
Step-by-step explanation:
In the equation y = m x + b
m is the rate of change ⇒ constantb is the initial value ⇒ constantx is the domain ⇒ inputy is the range ⇒ outputx is the independent variable because it does not depend on any value
y is the dependent variable because it depends on the value of x
Let us solve the question
∵ 5x + 2y = 150
→ Put it in the form above by subtracting 5x from both sides
∵ 5x - 5x + 2y = 150 - 5x
∴ 2y = 150 - 5x
→ Divide each term by 2 to make the coefficient of y equal 1
∴ y = 75 - 2.5x
∴ y = -2.5x + 75
→ Compare is by the form above
∴ m = -2.5 and b = 75
∴ x is the independent variable (domain)
∴ y is the dependent variable (range)
-3y+(1)/(5)=(2)/(3)x write in Ax+By=C
Answer:
2/3x + 3y = 1/5
Step-by-step explanation:
-3y + 1/5 = 2/3x (subtract 1/5)
-3y = 2/3x - 1/5 (subtract 2/3x)
-2/3x - 3y = -1/5 (divide by negative 1)
2/3x + 3y = 1/5

Triangle FED is the image of triangle ABC. Angle A corresponds with which angle?
A) D
B) E
C) F
D) none of the above
Answer:
C) F
Step-by-step explanation:
If you flip triangle ABC across the y-axis and slide it over top of triangle FED then you can see that angle A corresponds with angle F.

x = 70°
Explanation :
To find : Value of x
Here, given angles are :
35°, 75° and x
Knowledge Required to solve it :
The sum of all the angles of a triangle is 180°.
Now,
35°+75°+x=180°
⇒110°+x=180°
⇒x=180°-110°
⇒x=70°
.°. x=70°

3.05 Quiz: Congruent Polygons and Their Corresponding Parts. Pls help ;-;
Answer:
The correct options are presented as follows;
ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent
Step-by-step explanation:
The coordinate of the preimage point A = (-2, 1)
The coordinate of the image point A' = (2, 1)
Similar for points B(-5, -2) and B'(5, -2), C(-3, -4) and C'(3, -4)
Which is equivalent to a reflection across the y-axis
Similarly, we have;
The coordinate of the preimage point A' = (2, 1)
The coordinate of the image point A'' = (-1, 2)
Which is equivalent to rotation of 90° counterclockwise which involves transforming a preimage (x, y) to an image (-y, x)
Similar for points B and B', C and C'
Therefore, because the reflection transformation, and the rotation transformation, are rigid transformation, the figures of the preimage and the image are congruent
Therefore, we have;
ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent.

I need help, -3x+9+4x=10 just wondering if the answer is X=1
Answer:
it's correct good job :)
Answer:
Step-by-step explanation:
Answer: Fortunately, you don’t have to prove that x or y must be 1 or -1 in order for x*y to not be an element of G.
You only need to prove that x*y is an element of G for any x,y in G. (That’s what it means for * to be an operation on G.)
I haven’t thought yet about how to prove that, but let me give you some thoughts off the top of my head.
We know -1 < x, y < 1. We must show -1 < (x + y) / (xy + 1) and (x + y) / (xy + 1) < 1.
First, let’s show that -1 < (x + y) / (xy + 1).
I want to multiply xy + 1 to both sides, but we need to know whether it’s positive or not, so we know whether to reverse the inequality.
Well, -1 < x, y < 1 implies that xy > -1, which implies that xy +1 > 0.
So we must show that -(xy + 1) < x + y.
That is, let’s show that 0 < x + y + xy + 1. (I don’t know if this is going anywhere useful; I’m just playing around with algebra.)

The New England patriots scored 9 points in the first half. In the second half they scored 3 less than 2 times the points in the first half. What is the ratio of of the points and scored in the second half to the total number of points scored
Answer:
[tex]S : T = 5 : 8[/tex]
Step-by-step explanation:
Represent the first half with F and the second with S
We have that:
[tex]F = 9[/tex] --- From the first statement
[tex]S = 2F - 3[/tex] --- From the next statement
Required
Determine the ratio of S to the total point
First, we need to determine the value of S
Substitute 9 for F in [tex]S = 2F - 3[/tex]
[tex]S = 2 * 9 - 3[/tex]
[tex]S = 18 - 3[/tex]
[tex]S = 15[/tex]
Next, we determine the total points
[tex]Total = F + S[/tex]
[tex]Total = 9 + 15[/tex]
[tex]Total = 24[/tex]
The ratio of S to total is: (Represent total with T)
[tex]S : T = 15 : 24[/tex]
Divide both ration by 3
[tex]S : T = 15/3 : 24/3[/tex]
[tex]S : T = 5 : 8[/tex]
Hence, the ratio is 5 to 8

Simplify and Distribute
(−5)(4x)+(−5)(−2)=(−2)(3)+(−2)(6x)
−20x+10=−6+−12x
−20x+10=−12x−6
Adding 12x both sides.
−20x+10+12x=−12x−6+12x
−8x+10=−6
Subtract 10 both sides
−8x+10−10=−6−10
-8x = -16
Then divide both sides by 8
-8x/8 = -16/8
x=2
If you have a square with a perimeter of 18 inches, what is the area of the square after
scaling it by 7? Round to the nearest tenth is needed.
Answer:
992.3 in^2 to the nearest tenth.
Step-by-step explanation:
The new perimeter will be 7*18 = 126 inches.
So the side of the new square will be 126/4 = 31.5 inches,
and it's area = 31,5^2
= 992.25

Find f (h(-5))
f (x) 9x - 5
g(x) - 3x
h(x) 2x2
Your answer:
hi
You are making f ° h
f(x) = 9x-5
h(x) = 2x²
You must first calculate h(-5) : so remplace x by -5 in h :
h(-5) = 2 (-5)² = 2* 25 = 50
then apply f(x) to result : f(50) = 9 *50 -5 = 450 -5 = 445

Explain why the exponents cannot be added in the product 12^3 x 11^3?? I need a simple answer that won’t be confusing pls.
Answer:
The bases aren't the same
Step-by-step explanation:
If the bases are the same, then their exponents are added. In this case, since the exponents are the same, then 12^3*11^3=(12*11)^3=132^3=2299968
