Answer:
The options are not shown, so i will answer in a general way.
First, for a line of the form:
y = a*x + b
All the perpendicular lines will have a slope of -(1/a), then we can write a general perpendicular line as:
y = -(1/a)*x + c.
In this problem we have the perpendicular lines:
y=(s/t)*x+10
y = (q/r)*x - 4
Because those lines are perpendicular, we must have that:
(q/r) = -(1/(s/t)) = -(t/s)
q/r = -t/s
and we knew that s, t, q and r are integers (where t and r can not be equal to zero), and because of this relation, where we can see that in the denominator at the right we have the integer s, we can conclude that s can not be zero (we can not divide by zero).
And we know that t and s are both different than zero, then:
-t/s ≠ 0.
This means that:
q/r ≠ 0
And from this, we can conclude that q is different than zero.

Answer:
4) (4, 0)
Step-by-step explanation:
I find it useful to graph the inequalities and the points.
The point on the dashed line is not in the solution set. The only point in the doubly-shaded area is (4, 0), choice (4).
__
Another method of choosing the points is to try them in the inequalities. I find it easier to do the math if the inequalities are written in standard form:
2y < x +8 . . . . . multiply the first by 2
x -2y > -8 . . . . . add -8-2y and swap sides. This is the first inequality.
__
y ≥ -x +1
x + y ≥ 1 . . . . . add x. This is the second inequality
__
For the four points in the first inequality, we have ...
1) -5 -2(3) = -11 . . . not greater than -8
2) 0 -2(4) = -8 . . . not greater than -8
3) 3 -2(-5) = 13 . . . greater than -8, satisfies the first inequality
4) 4 -2(0) = 4 . . . greater than -8, satisfies the first inequality
__
So, the two points that might possibly work are (3, -5) and (4, 0). Here, we try these in the second inequality.
3) 3 -5 = -2 . . . less than 1
4) 4 + 0 = 4 . . . greater than 1, satisfies the second inequality
The only point listed that is a solution to the system is (4, 0), point 4.

Given the functions below, find the products identified.
f(x) = 7x - 9
g(x) = -2x + 1
h(x) = 3x + 5
j(x) = -x - 11
What is the product of f(x) and g(x)?
Answer:
f(x) * g(x) =(7x-9)(2x+1)
=14x^2+7x-18x-9
=14x^2-11x-9

Six less than 4 times a number is -15 (How to write in equation form?)
Answer:
4x - 6 = -15
Step-by-step explanation:
six less basically means minus 6
something times a number is usually the number given then n (or i usually just like to use x) so in this case 4n or 4x
'is' basically means equal to
put it all together and you get 4x - 6 = -15

Describe the relationship between the point B(16,24) and the point A(8,12) in terms of dilations.
Answer:
howwwwwwwww
Step-by-step explanation:
Points have linear dilation.
LInear systemIn this, the power of x is one.
Given
A (8,12)
B (16. 24)
How to get the relationship?Let the relationship is y = mx + c,
Then at A (8. 12)
12 = 8m + c ......(1)
Then at B (16, 24)
24 = 16m + c .......(2)
From equation 1 and 2 we get
[tex]m = \dfrac{3}{2} \\\\c =0[/tex]
Then, our equation will be
[tex]y = \dfrac{3}{2} x[/tex]
Thus. points have linear dilation.

What is the slope of the line?
Answer:
it may be steep slop if it is social study
Hello!
[tex]\large\boxed{m = \frac{3}{2}}[/tex]
[tex]\large\boxed{\text{Slope = \frac{3}{2}}}[/tex]
Use given points and plug them into the slope formula to find the slope of the line:
[tex]\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }[/tex]
We can use the points (2, -1) and (0, -4) to solve:
[tex]\text{Slope } = \frac{ -1 - (-4) } { 2 - 0 }\\\\= \frac{3}{2}[/tex]
Therefore, the slope, or "m" value of the line is 3 / 2.

Suppose a publishing company estimates that its monthly cost is C(x) = 600x ^ 2 + 300x and its monthly revenue is R(x) = - 0.4x ^ 3 + 700x ^ 2 - 600x + 500 , where xis in thousands of books sold. The profit is the difference between the revenue and the cost What is the profit function, P(x)
Answer: [tex]P(x)= - 0.4x ^ 3 +100x^2-900x+500[/tex]
Step-by-step explanation:
Given: Monthly cost : [tex]C(x) = 600x ^ 2 + 300x[/tex]
Monthly revenue : [tex]R(x) = - 0.4x ^ 3 + 700x ^ 2 - 600x + 500[/tex], where x is in thousands of books sold.
Profit = Revenue - Cost
Now , Profit function : P(x) = R(x)-C(x)
[tex]=- 0.4x ^ 3 + 700x ^ 2 - 600x + 500 - ( 600x ^ 2 + 300x )\\\\= - 0.4x ^ 3 + 700x ^ 2 - 600x + 500 -600x ^ 2 - 300x\\\\= - 0.4x ^ 3 +100x^2-900x+500[/tex]
Hence, [tex]P(x)= - 0.4x ^ 3 +100x^2-900x+500[/tex]

If Yasai purchased and received 100 bags of noodles before the year end, if no payment has been made, how should this be represented in the current 2019 accounting period? I.E. For the year ending 31 December 2019.
Answer:
the journal entry to record this transaction is:
Dr Merchandise inventory XY
Cr Accounts payable XY
Since Yasai received the merchandise before the year ended, it must report this transaction by increasing both current assets (merchandise inventory) and current liabilities (accounts payable).
Under accrual accounting, transactions are recorded once they occur, and not necessarily when cash is exchanged. In this specific case, the company received an asset and it must pay for it at a later date.
