Step-by-step explanation:
Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.
As we can see, the problem can be solved in a single step, as it is just basic algebra. I'll start off with explaining the formula.
So what it is saying is that [tex]3^2=9[/tex] and that [tex]2^3=8[/tex]. We know that since [tex]3^2=3*3=9[/tex] and [tex]2^3=2*2*2=8[/tex].
Keep in mind that exponents are just the number of how many times the number is multiplied by itself.
Now that we know that, we can go into the second equation, it states that [tex]8+9=17[/tex] and it has relevancy because our top two equations give us the answers of 8 and 9.
Since we know what our answer is due to the 3rd question telling us. We can say that the final equation is true:
[tex]3^2+2^3=17?\\9+8=17?\\17=17[/tex]
After all of our reasoning, it is correct.

What is the solution for the system of equations? Use the substitution method to solve. 2x+y=20−5y=−6x+12 Enter your answer by filling in the boxes. ( , )
Answers
Answer:
(7, 6 )
Step-by-step explanation:
2x + y = 20 ( subtract 2x from both sides )
y = 20 - 2x → (1)
- 5y = - 6x + 12 → (2)
Substitute y = 20 - 2x into (2)
- 5(20 - 2x) = - 6x + 12 ← distribute parenthesis on left side
- 100 + 10x = - 6x + 12 ( add 6x to both sides )
- 100 + 16x = 12 ( add 100 to both sides )
16x = 112 ( divide both sides by 16 )
x = 7
Substitute x = 7 into (1)
y = 20 - 2(7) = 20 - 14 = 6
solution is (7, 6 )

The length of the rectangle is 2x + 8 cm and the width is 2cm . The area of the rectangle is 12 cm
Answers
Answer:
x = - 1
Step-by-step explanation:
Length ( l ) = 2x + 8 cm
Width / Breadth ( b ) = 2 cm
Area ( rectangle ) = 12 cm
Formula : -
Area ( rectangle ) = lb
12 = ( 2x + 8 ) ( 2 )
Divide 2 on both sides,
12 / 2 = ( 2x + 8 ) ( 2 ) / 2
6 = 2x + 8
2x + 8 = 6
2x = 6 - 8
2x = - 2
x = - 2 / 2
x = - 1
write the equation of the line that passes through the points (3,1) and (-2,6) in slope intercept form
Answers
Answer:
y = - x + 4
Step-by-step explanation:
First find slope:
6-1/-2-3 = 5/-5 = -1
Then plug one point and slope into point slope form: y-y1 = k (x-x1)
Plug in (3, 1) and slope -1 --> y-1 = -1(x-3)
Simplify --> y - 1 = - x + 4
Then add 1 to both sides --> y = -x + 4

11. Commercial jets fly between 30,000 ft and 36,000 ft. About how many hours of growing could
pass before the beanstalk might interfere with commercial aircrafts? Explain how you got your
answer
Answers
An exponential function is a function that increases rapidly as the time increases.
The number of hours that passes before the magical beanstalk interferes with commercial flight is approximately 9.384 hours.Reasons:
The function that gives the height of a beanstalk is presented as follows;
b(t) = [tex]3^t[/tex]
When the height is 30,000 ft., we have;
30,000 = [tex]3^t[/tex]
㏑(30,000) = t·㏑(3)
[tex]\displaystyle t = \mathbf{\frac{ln(30,000)}{ln(3)}} \approx 9.384[/tex]
The time it would take the beanstalk to grow 30,000 ft., t ≈ 9.384 hours
Similarly, the time it would take the beanstalk to grow to 36,000 ft. is found as follows;
[tex]\displaystyle t_{36,000} = \mathbf{\frac{ln(36,000)}{ln(3)}} \approx 9.55[/tex]
The time it would take the beanstalk to grow 36,000 ft., t ≈ 9.55 hours
The number of hours it will take the beanstalk to grow to 30,000 feet at
which it might interfere with commercial aircrafts is 9.384 hours.

Answer:
m< WXZ = 73
m< ZXY = 87

Answers
The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160
Inequalities shows the non equal comparison of numbers or expressions.
Let x represent the number of packages of 24 notepads and y represent the number of packages of 6 notepads
Since the organizers need to do at least 200 notepads, hence:
24x + 6y > 200
Also, they have a budget of $160. Let us assume that each 24 package cost $16 and each 6 package cost $5.40, hence:
16x + 5.40y ≤ 160

If x+y= -4 and xy=2, then find the value of x²+y²
Answers
Answer:
x² + y² = 12
Step-by-step explanation:
x + y = -4
xy = 2
x² + y² = (x+y)² - 2xy = (-4)² - 2(2) = 16 - 4 = 12
Xy=2
(x+y)^2= x^2+y^2+2xy
(-4)^2=x^2+y^2+2(2)
16 = x^2+y^2+4
x^2+y^2=16-4
