Step-by-step explanation:
__________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
Any number having 0 as its exponent , the overall result will be 1. For e.g. :- [tex]a^0 = 1[/tex] (where 'a' is any number).Lets say there's a number 'a' having '- x' as its exponent , then - [tex]\frac{1}{a^{-x}} = a^x[/tex]__________________________________________________________
Lets put random values in place of x.
Let x be 0.
Putting x = 0 in the eqn. 3x - y = 12 gives the value of y.
[tex]=> 3 \times 0 - y = 12[/tex]
[tex]=> -y = 12[/tex]
[tex]=> y = -12[/tex]
So, we can conclude that by putting x = 0 , we get y = -12.
Now , putting x = 0 & y = -12 in [tex]\frac{8^x}{2^y}[/tex] gives -
[tex]=> \frac{8^0}{2^{-12}} = \frac{1}{2^{-12}} = 2^{12}[/tex]

15. A hot dog stand sells of its hot dogs before noon, and of its hot dogs after noon. At the
end of the day they have 21 hot dogs left. How many hot dogs did they sell?
PLEASE HELP WILL MARK BRAINLEST!
Answers
Answer:
Step-by-step explanation:
The first thing to do is convert to a common denominator.
So 1/2 =4/8. That means the vendor sold 4/8+3/8=7/8 of its hot dogs. 280 = 7/8. Now if you divide 280 by 7, you get 1/8 (answer = 40). The vendor sold 7/8 and 1/8 was left, which = 40. 8/8 would be 280 + 40 = 320.

Answers
Answer:
The point is at about (4.5, 100).
Step-by-step explanation:
Minka's line is p = 22t, which has a y-intercept of 0.
Kenji's line is p = 50 + 11t, which has a y-intercept of 50.
Find the line with y-intercept at 0 and the line with y-intercept at 50. Follow the two lines until they intersect. The point of intersection is about (4.5, 100).
You can find this point by setting the two equations equal to each other:
22t = 50 + 11t
Subtract 11t from both sides.
11t = 50
t = 50/11 ≈ 4.545
Then you can find the p value for this point by plugging t = 4.545 into either equation.
p = 22(4.545) = 99.99
p = 50 + 11(4.545) = 99.995
On the graph the point is about (4.5, 100).
You prepare8 scoops of dog food for 4 dogs, and prepare15 scoops of dog food for 6 dogs. Is there a proportional relationship between the number of scoops and the number of dogs?
Choose the correct answer below.
Answers
Answer:
Is there a proportional relationship between the number of scoops and the number of dogs?
No.
Step-by-step explanation:
A proportional relationship is something like:
y = k*x
Here y can represent the number of scoops of dog food, and x the number of dogs.
First, we know that for 4 dogs he prepares 8 scoops of dog food, then:
8 = k*4
If the relationship is proportional, then we should have a similar equation for the case of 6 dogs, where he prepares 15 scoops of dog food:
15 = k*6
So if we have the same k in both equations, then there is a proportional relationship between the number of scoops and the number of dogs.
In the first equation we have:
8 = k*4
8/4 = k
2 = k
And in the second equation we have:
15 = k*6
15/6 = k
2.5 = k
The values of k are different, so no, there isn't a proportional relationship between the number of scoops and the number of dogs.

Answer:
E and I are alternate interior angles, therefore are congruent
m∠E = m∠I = 60°E and F are complementary, therefore add to 90°
m∠F = 90° - 60° = 30°H and I supplementary, therefore add to 180°
m∠H = 180° - 60° = 120°Is 17/34 and 32/64 proportional why or why not?

Answers
Answer:
-13
Step-by-step explanation:
Opposite of 9t = -9t
Taking the sum of 9t - 13 and -9t
Sum = 9t - 13 + (-9t)
Sum = 9t - 13 - 9t
Sum = 9t-9t - 13
Sum = -13
Hence the expression in standard form is -13
