Answer:
3x + 10 y = -80
Step-by-step explanation:
We are given the equation y = −3/10x − 8 and we want to write it in standard form.
Standard form is written as ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot equal 0 and a cannot be negative.
The equation is currently is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.
As you can see, in standard form, x and y are on both sides, but in slope-intercept, the equation is solved for y.
So, to start, we can add 3/10x to both sides.
y = -3/10x - 8
+3/10x +3/10x
_______________
3/10x + y = - 8
Now, we have x and y on the same side, but remember that the the coefficients should be integers (non-fractions).
So, we need to clear the fraction.
Multiply both sides by 10.
10(3/10x + y) = 10(-8)
3x + 10y = -80

y = 0
Step-by-step explanation:
x - y = 2
2x + 3y = 4
Using creamers rule of determinants, we have;
D =
|1 1|
|2 3|
Thus; D = (1 × 3) - (1 × 2)
D = 1
Dx =
|2 1|
|4 3|
Dx = (2 × 3) - (1 × 4)
Dx = 2
Dy =
|1 2|
|2 4|
Dy = (1 × 4) - (2 × 2)
Dy = 0
Thus;
x = Dx/D = 2/1
x = 2
y = Dy/D = 0/1
y = 0

What is the product of 2 rad 5 and 10 rad 30 in simplest radical form?
Answer: 100√6
Step-by-step explanation:
Start out by multiplying the 2 by the 10 to get 20.
Then, multiply √5 and √30 together to get √150. The largest perfect square within √150 is √25 (don't forget about your √6)
√25 is 5. Multiply your 20 and 5 together to get 100, and then put your √6 next to the 100 since it cannot be added or multiplied since they are not like-terms.
Thus, leaving you with an answer of 100√6.
Graph the logarithmic function below by moving the
key point.
y = log₂ (x)
You can only graph integer points
To graph the logarithmic function y = log₂(x), we can use the key point (1,0) and the fact that the logarithmic function is the inverse of the exponential function y = 2ˣ.
Starting at the key point (1,0), we can move to the right by increasing x by a factor of 2, since log₂(2) = 1. This takes us to the point (2,1). Similarly, we can move to the right by a factor of 2 again to get to the point (4,2), and then to (8,3), (16,4), and so on.
If we instead move to the left from the key point (1,0) by a factor of 2, we get to the point (1/2, -1), since log₂(1/2) = -1. We can continue moving to the left by dividing x by 2 to get to (1/4, -2), (1/8, -3), and so on.
The given graph of y = log₂(x) using only integer points.
The graph is symmetric about the line x=1, since log₂(x) = log₂(1/x) = -log₂(x).

An artificial pond is stocked with an initial population of 2,500 fish. The engineers estimate a 24% decline in the fish population over time without restocking or effects of fishing. The following function models the population, where x is the number of years since the pond was made.
f(x) = 2,500(0.76)x
The mathematical range of the function is y > 0. Which statement describes how the reasonable range compares to the mathematical range?
The reasonable range has a minimum value of 2,500.
The reasonable range has a maximum value of 2,500.
The reasonable range has a reasonable minimum that cannot be determined.
The reasonable range has a reasonable maximum that cannot be determined.
Answer:
B) the reasonable range has a maximum value of 2,500
Step-by-step explanation:
The reasonable range has a maximum value of 2500.
What is mathematical range?
'The Range is the difference between the lowest and highest values.'
According to the given problem,
f(x) = 2500 × [tex]0.76^{x}[/tex]
Number of years = x
⇒ x ≥ 0
⇒ f(x) ≤ 2500 × [tex]0.76^{0}[/tex]
= 2500
Hence, we can conclude, the reasonable range has a maximum value of 2500.

The volume of Cube A is 64 cubic inches. The face of Cube B has an area of 81 square inches. Which cube has a greater side length?
The side length of Cube A is inches. The side length of Cube B is
(Simplify your answers.)
inches Cube
has a greater side length.
The answer to this question is:
Cube B has greater side length.
We know that the volume of cube = ( a )³
(where a represents the cube's sides length.)
Given that:
Volume of Cube A = 64 cubic inches = 64 in³
Volume of Cube B = 81 cubic inches = 81 in³
Length of side by cube = ∛Volume
Length of side of Cube A = ∛64 = ∛ 2*2*2*2*2*2*
= 2*2
= 4 inches
Length of side of Cube B = ∛81 = ∛ 3*3*3*3
= 3√3
=3*1.732 = 5.196 inches
Length of side of cube A < Length of side of cube B
4 inches < 5.196 inches
Thus, Cube B has greater side length.
Therefore, Cube B has greater side length.

2. Grant works as a salesperson at a seasonal market. During the Christmas season, he
gets a 15 percent commission on every tree he sells. If he sold 12 trees today, with an
average sale price of $35 per tree, what amount of commission will he make?
Grant will make $63 commission on 12 trees he sold.
Given that, Grant works as a salesperson at a seasonal market. He gets a 15 percent commission on every tree he sells. If he sold 12 trees then we have to calculate the amount of commission he will get if the average sales price of a tree is $35.
So, first we will calculate the amount of commission Grant will get if he sold one tree.
∴ The commission on one tree will be equals to 15 percent on the sales price of a tree i.e., $35.
⇒ 15% of $35
= 15/100 x 35
= 5.25
Therefore, Grant will get $5.25 commission on selling one tree.
He sold 12 trees on that day. So, the total amount of commission he will get on 12 trees will be equal to,
= 12 x 5.25
= 63
Therefore, $63 is the amount of commission Grant will made on the sale of 12 trees.

Answer: Apple price = Rs 75 per kg & Orange price = Rs 45 per kg
Step-by-step explanation:
Creative Section- A
a) 4kg apples + 6 kg oranges = Rs 570
3kg apple price = 5 kg orange price
Let, apple = x , orange = y
Now, 4x+6y= 570
3x=5y ⇒ 3x-5y= 0
Subtract two equations,
x+11y=570
⇒ x + (33x/5) = 570
⇒ 7.6x = 570
⇒ x = 75, y= 45
Apple price = Rs 75 per kg
Orange price = Rs 45 per kg

Hey there!
“-3 < x - 10”
SOME people treat the “<” “>” as an equal sign to make these types of problems easier to solve!
-3 = x - 10
Flip the equation around
x - 10 = -3
ADD both of your sides by 10
Like: x - 10 + 10 = -3 + 10
CANCEL out: -10 + 10 because it gives us 0
Keep: -3 + 10 because it gives us the value of x
-3 + 10 = x
Solve that above and you have your answer: x = 7 ☑️
Overall answer: x < 7
