Answer:
The answer to the first one is y=3/2x-27/2
The answer to the second one is y=-3/5x+6/5
Step-by-step explanation:
1. 2y-3x=-27
first, you want to add '3x' to both sides.
2y=3x-27
then you want to divide '2' from both sides. you do not want to use the 'y' because you want to keep the 'y' on its own side.
y=3/2x-27/2
2. 5y+3x=6
First, you want to subtract '3x' from both sides.
5y=-3x+6
Now, you want to divide '5' from both sides.
y=-3/5x+6/5

Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles

Answer:
D
Step-by-step explanation:
Solving the inequality
2x + 3 ≤ 5 ( subtract 3 from both sides )
2x ≤ 2 ( divide both sides by 2 )
x ≤ 1
The required number line will have a solid circle at x = 1 and the arrow will be going left.

Rachel has 2/3 pound of snack mix. She eats 5/12 of the snack mix. How much of the snack mix did Rachel eat?
Answer: Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.
Step-by-step explanation:
Given : Rachel has [tex]\dfrac23[/tex] pound of snack mix..
If she ate [tex]\dfrac5{12}[/tex] of the snack mix.
Then, Quantity of snack mix eaten by Rachel = [tex]\dfrac5{12}\times\dfrac23[/tex]
[tex]=\dfrac56\times\dfrac13\\\\=\dfrac{5}{18}[/tex]
Hence, Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.
If the principle is $4,000 and the rate of interest is 8% (simple interest), what is the amount of interest after one year?
Answer: $320
Step-by-step explanation:
A principal of $4,000 was invested.
The principal increases at a rate of 8% every year by simple interest.
After 1 year the total in the account can be calculated by the formula:
= Principal * ( 1 + rate * time)
= 4,000 * ( 1 + 8% * 1)
= $4,320
Interest:
= Amount after a year - original price
= 4,320 - 4,000
= $320

the base ratio of unused tape to used tape is 24:16.
then we have to simplify,
both 16 and 24 can be divided by eight,
24 divided by eight is 3
16 divided by eight is 2
therefore, our simlpified ratio is 3:2

brainliest. follow anything . box of chocolates contains seven milk chocolates and six dark chocolates. Five of the milk chocolates and four of the dark chocolates have peanuts inside. You randomly select a chocolate and eat it. What is the probability it is a dark chocolate with peanuts?
options=2/3, 4/13, 11/13 and 8/13
Answer: 4/13
Step-by-step explanation: There are a total of 13 chocolates, and 4 of those are dark chocolate with peanuts.
Probability that the chocolate you eat is a dark chocolate with peanuts is 4/13.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Total number of milk chocolates = 7
Total number of dark chocolates = 6
Number of milk chocolates that have peanuts inside = 5
Number of dark chocolates that have peanuts inside = 4
Total number of chocolates = 7 + 6 = 13
Probability that the randomly selected chocolate is a dark chocolate with peanuts = 4/13
Hence the required probability is 4/13.

Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)
Answer:
An exponential function in the form y=9(4ˣ)
Step-by-step explanation:
Step(i):-
Given that exponential function
y = a bˣ ...(i)
The equation (i) passes through the point (0,9)
9 = a (b )⁰ = a
a =9
Step(ii):-
The equation (i) passes through the point (3,576)
576 = 9(b)³
⇒ [tex]\frac{576}{9} = b^{3}[/tex]
⇒ 64 = b³
⇒ 4³ = b³
[tex](4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }[/tex]
b = 4
Final answer:-
An exponential function in the form y=abˣ
An exponential function in the form y=9(4ˣ)

I’ll mark you as a brainliest:) .
Answer:
Step-by-step explanation:
a) Since we know that y=x^3, we can plug the values in
They would be: (-2)^3, (-1)^3, (0)^3, (1)^3, and 2^(3)
Which would be -8, -1, 0, 1, and 8
b) since we know that y=x, we can plug the values in
They would be -2, -1, 0, 1, and 2 because x = y
