An airplane is loaded with cargo and ready to take off. Before it departs, an unknown number of 8 pound boxes, b, will be taken off the plane and a 600 pound crate will be put on. To keep the plane in balance, no more than 400 pounds may be taken off the plane. Write an inequality that best describes this situation.
b. Write the inequality that describes this situation.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Number of 8 pounds before boxes to be removed from cargo = b
Weight in pound of crate to be loaded into cargo = 600 pounds
To achieve a balance , no more Than 400 pounds may be taken off the plane
Hence,
Number of pounds removed must not be more than 400 pounds
(8 pounds * b) ≤ 400
8b ≤ 400
Divide both sides by 8
b ≤ 50

What is the new function’s equation (green)?
Answers
Answer:
[tex]f(x)=-(x+3)^2[/tex]
Step-by-step explanation:
The parent function is f(x) = x^2.
This can be reasoned by the fact that this is a postive parabola that is on the origin.The green function is moved 3 units to the left. This means that the function changes like this:
[tex]x^{2}[/tex] --> [tex](x+3)^2[/tex]The green function is also reflected over the x-axis.
Functions that are reflected over the x-axis take are multiplied by an exterior negative (literally, a negative on the outside)
Ex; f(x) flipped over x-axis= -f(x)So, we put a negative on the outside.
[tex](x+3)^2[/tex] --> [tex]-(x+3)^2[/tex]
The function isn't moved up or downwards, so we don't have to add or subtract anything on the outside.
The function is also not stretched or shrunk.
So, the equation of the green function is:
[tex]f(x)=-(x+3)^2[/tex]

To get the top number in the X you do 7x^2*-20 that’s how the -140x^2 came
Than the bottom is just the middle number which is -31x.
For te side numbers they have to be something when multiplied together you get the top number but also when you add them together you get the bottom. And -35x*4x gives you -140x^2. And -35x+4x gives you -31x.
Then for the box it looks like she put the numbers/letter you multiply to be able to get the answers. 7x*x. Gives you 7x^2. And 7x*-5 gives you -35x. So on...

find the distance between the points (2, 7) and (-6, -2).
Answers
Answer:
Approximately 12.04 units.
Step-by-step explanation:
The find the distance between any two points, we can use the distance formula, which is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
We have the points (2,7) and (-6,-2). Let's let (2,7) be (x₁, y₁) and let's let (-6, -2) be (x₂, y₂). Substitute:
[tex]d=\sqrt{(-6-2)^2+(-2-7)^2[/tex]
Subtract:
[tex]d=\sqrt{(-8)^2+(-9)^2[/tex]
Square:
[tex]d=\sqrt{64+81}[/tex]
Add:
[tex]d=\sqrt{145}[/tex]
Approximate
[tex]d=\sqrt{145}\approx12.04[/tex]
So, the distance between (2,7) and (-6,-2) is approximately 12.04 units.

Find the third side in simplest radical form :
Answers
Answer:
2√41
Step-by-step explanation:
If the third side is x, we can use the Pythagorean Theorem (a² + b² = c² where a and b are legs and c is the hypotenuse - a and b would be 12 and √20 and c would be x) to write the following equation:
12² + (√20)² = x²
144 + 20 = x²
164 = x²
√164 = √x²
x = ±√164 = ±2√41
x = -2√41 is an extraneous solution because x cannot be negative, therefore, the answer is x = 2√41.

Step-by-step:

y=-61/2=-30 1/2=-30.5
Step-by-step explanation:
Add −15 and 7 to get −8.
−8+17=2y+70
Add −8 and 17 to get 9.
9=2y+70
Swap sides so that all variable terms are on the left hand side.
2y+70=9
Subtract 70 from both sides.
2y=9−70
Subtract 70 from 9 to get −61.
2y=−61
Divide both sides by 2.
y=-61/2
Fraction
−61/2 =−30.5 can be rewritten as − 61/2=−30.5 by extracting the negative sign.
y=-61/2=-30 1/2=-30.5
