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

Answer:
hat = 5pumpkin = 2ghost = 7cauldron = 10Step-by-step explanation:
Using h, p, g, c to represent the values of the hat, pumpkin, ghost, and cauldron, respectively, we can write 5 equations:
gh +h = 40cp +p = 22g +2c = 27ph +g = 172g +h = 19Solving the last equation for h, and substituting into the first equation gives ...
h = 19 -2g
g(19 -2g) +(19 -2g) = 40
2g^2 -17g +21 = 0 . . . . . . . . write in standard form
(2g -3)(g -7) = 0 . . . . . . . factored form
The values of g that make the factors zero are g = 3/2 and g = 7. If we assume the solution is restricted to integer values, then g = 7, and ...
h = 19 -2·7 = 5
From equation 4, ...
5p +7 = 17 ⇒ p = 2
From equation 3, ...
7 +2c = 27 ⇒ c = 10
The values of the symbols are ...
hat = 5pumpkin = 2ghost = 7cauldron = 10_____
Check
Equation 2 becomes ...

ANSWER NEEDED ASAP!!!!!
If 2k - 3 = 9 (k+7)-3 then k is ????
Answer:
k= -9
Step-by-step explanation:
2k-3=9k+63-3 [expand the 9(k+7) first]
2k-9k=63-3+3 [put the like terms together]
-7k=63 [do the simple math]
k= 63 ÷ by -7
k=-9
Answer:
K = -9
Step-by-step explanation:
2k-3 = 9(k+7)-3
2k-3 = 9k+63-3
2k-3 = 9k+60
2k-9k = 60+3
-7k = 63
-k = 9
k = -9

Does each equation represent a proportional relationship? Choose Yes or No.
y = 7x – 3
Choose...
y = 150x
Choose...
Hi there!
»»————- ★ ————-««
I believe your answer is:
[tex]y = 7x - 3\leftarrow \text{No.}\\\\y = 150x \leftarrow \text{Yes.}[/tex]
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
[tex]\boxed{\text{General Proportional Formula:}}\\\\y = kx\\\rule{150}{0.5}\\$\bullet \text{ } k - \text{Constant of Proportionality}\\\rule{150}{0.5}\\\text{Since } y=150x \text{ is in this form, we can say that it is a proportional relationship.}\\\rule{150}{0.5}\\\text{We can also tell if something is proportional by graphing them.}[/tex]
[tex]\textbf{Proportional graphs go through the origin.}[/tex]
⸻⸻⸻⸻
Since y = 7x - 3 does not pass the origin, it is not proportional. However, y = 150x does, so it is proportional.

(7 x 10^5) divided by (2 x 10^2) in standard form
Answer:
3.5x10³
Step-by-step explanation:
7x10^5=700000
2x10^2=200
Divide both by 100
7000÷2=3500
divide by 1000 as standard form is less than 10
1000 is 10 cubed
3500÷1000 is 3.5
