49. The line containing (1, -3) and (3, y) is parallel to the line containing (5, -6) and (9, y).
How do I find y?
Answer:
y = 0
Step-by-step explanation:
Parallel lines have equal slopes
Calculate the slopes of both lines and equate them
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 3 ) and (x₂, y₂ ) = (3, y )
m = [tex]\frac{y-(-3)}{3-1}[/tex] = [tex]\frac{y+3}{2}[/tex]
Repeat with (x₁, y₁ ) = (5, - 6 ) and (x₂, y₂ ) = (9, y )
m = [tex]\frac{y-(-6)}{9-5}[/tex] = [tex]\frac{y+6}{4}[/tex]
Equating the 2 expressions
[tex]\frac{y+3}{2}[/tex] = [tex]\frac{y+6}{4}[/tex] ( cross- multiply )
4(y + 3) = 2(y + 6) ← distribute parenthesis on both sides
4y + 12 = 2y + 12 ( subtract 2y from both sides )
2y + 12 = 12 ( subtract 12 from both sides )
2y = 0 , then
y = 0

Prove sum of interior angle triangle is 180
Given :-
A triangle ABC .To prove :-
Sum of interior angles of a ∆ is 180° .Construction :-
Draw a line MCN parallel to AB . Extend line AB to K .Proof :-
In ∆ ABC , we have ,
[tex]\angle[/tex] BAC + [tex]\angle[/tex] BCA = [tex]\angle[/tex] CBKAs sum of two interior angles of a triangle is equal to the opposite exterior angle .
Also ,
[tex]\angle[/tex] ABC + [tex]\angle[/tex] CBK = 180°( linear pair )
Hence from above two ,

Answer:
y = -2x
Step-by-step explanation:
When it is x is -5, y is double of x multiplied into -1.
Hence, it is y = -2x
We can take a couple examples,
i) When x = -5,
y = -2(-5)
= 10
ii) When x = -10,
y = -2(-10)
= 20
and so on.

FIRST PERSON TO ANSWER GET BRAINLYEST Madie drove 200 miles at a speed of 50 miles per hour. Which equation will help you find the number of hours she was driving?
StartFraction 50 miles Over 1 hour EndFraction = StartFraction 200 miles Over question mark hours EndFraction
StartFraction 50 miles Over 1 hour EndFraction = StartFraction question mark hours Over 200 miles EndFraction
StartFraction 200 miles Over 1 hour EndFraction = StartFraction 50 miles Over question mark hours EndFraction
StartFraction 200 miles Over 1 hour EndFraction = StartFraction question mark hours Over 50 miles EndFraction
Answer:
200/50=h
h=number of hours
Step-by-step explanation:
Maddie drove 200 miles at a speed of 50 miles per hour.
As we know
speed = miles/hours
and to calculate we use the formula
Hour = miles/speed
So the equation that helps to find the number of hours she was driving =
h = 200/50
Equation will be h = 200/50
Answer: StartFraction 50 miles Over 1 hour EndFraction = StartFraction 200 miles Over question mark hours EndFraction
Step-by-step explanation:
For constant speed, miles and hours are proportional. One possible equation is ...
_____
I personally like to put the unknown in the numerator, so the equation can be solved in one step. The equation above requires two steps: one to cross-multiply, and one to divide by 50.
I might write the equation as ...
(? hours)/(200 mi) = (1 hour)/(50 mi) . . . . multiply by 200 mi to solve
Another way to write the equation is matching the ratios of times to corresponding miles:
(? hours)/(1 hour) = (200 mi)/(50 mi)
This only requires simplification to solve it: ? = 4.
So it would be A.

In Exercises 13-20, find the value of x so that the function has the
given value.
13. f(x) = 6x; f(x) = -24
14. g(x) = -10x; g(x) = 15
15. f(x) = 3x – 5; f(x) = 4
16. h(x) = 14 – 8x; h(x) = -2
Step-by-step explanation:
13. f(x) = 6x; f(x) = -24
6x = -24
x = -4
14. g(x) = -10x; g(x) = 15
-10x = 15
x = -1.5
15. f(x) = 3x – 5; f(x) = 4
3x-5 =4
3x =9
x = 3
16. h(x) = 14 – 8x; h(x) = -2
14-8x=-2
-8x = -16
x = 2

2x + y2 = 6
Answer:
NOT a function
Step-by-step explanation:
y^2 (not y2) is "the square of y"
The given 2x + y^2 = 6 can be solved for y as follows:
Subtracting 2x from both sides, we get y^2 = 6 - 2x, whose y-values are y = ±√(6 - 2x). Because there are two y-values associated with each x value, this is NOT a function. In a function there is only one y value for each x value.
54 divided by what equals 9?
Answer:
6
Step-by-step explanation:
After divide, the solution of the expression is,
⇒ 54 ÷ 9 = 6
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The expression is,
⇒ 54 ÷ 9
Now, We can divide as;
⇒ 54 ÷ 9
9 ) 54 ( 6
- 54
------
