x + y = 16
16x + 9y = 165
Multiply first equation by 9 and subtract the equations.
9x + 9y = 144
-(16x + 9y = 165)
-7x = -21
x = 3
Now substitute this x value into the first equation
x + y = 16
3 + y = 16
y = 13
If x+3=5, what is the value of 2(x+4)?
x equals 2, and substituting x=2 into the equation 2(x+4) gives us the result 12.
Explanation:To determine the value of 2(x+4), we begin by solving the equation x+3=5. Subtracting 3 from both sides yields x=2. Substituting this into 2(x+4), we get 2(2+4), which simplifies to 2(6). Multiplying, we find the result to be 12. The process involves solving for x by isolating it in the initial equation, then substituting this value into the expression we seek to evaluate. In this case, x=2, making 2(x+4) equal to 2 times the sum of 2 and 4, resulting in 12. This algebraic approach allows us to systematically find the desired value based on the given information.

Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie crochets at a rate of
of a blanket per day. She has 60 days until when she wants to donate the blankets, but she also wants to
skip crocheting some days so she can volunteer in other ways.
Write an inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.
How many days can Darcie skip to still meet her goal?
Answer:
I believe it's 15 days
Answer:
The maximum number of days that she can skip crocheting is s = 57
Step-by-step explanation:
Darcie wants to crochet a minimum of 3 blankets.
She can crochet at a rate of a blanket per day, so she makes 1 blanket in one day.
She has a total of 60 days to work.
If X is the number of days that she works, we can write it as:
X ≥ 3
This means that she works at least 3 days, so she makes at least 3 blankets.
X < 60
This means that she not can work 60 days or more, in this way she has at least one day to do another volunteer job.
then
3 ≤ X < 60
then we have:
1 ≤ s ≤ 60 - 3 = 57
where s is the days that she can skip, where the less or equal sign is used because we have a bigger or equal sign previously.
The maximum number of days that she can skip
The maximum number of days that she can skip crocheting is when the right equality is true, so s = 57.

The question is missing important data. The quadrilateral having vertices A, B, C and D is a cyclic quadrilateral.
Answer:
B) 85°
Step-by-step explanation:
Given:
A cyclic quadrilateral with ∠A is 95° and ∠B is 105°.
For a cyclic quadrilateral, the sum of the opposite interior angles is equal to 180°
Therefore, sum of angles A and C is 180°.
[tex]\angle A + \angle C=180\°\\95\°+\angle C=180\°\\\angle C=180-95\\\angle C =85\°[/tex]
Therefore, the correct option is option B) 85°

If the graph of function g is 6 units below the graph of function f, which could be function g? f(x) = -2x + 7 A. g(x) = -2x + 1 B. g(x) = -2x − 6 C. g(x) = -6x + 7 D. g(x) = -2x + 20
Answer:
A. [tex]g(x)=-2x+1[/tex]
Step-by-step explanation:
Given:
[tex]f(x)=-2x+7[/tex]
The function [tex]f(x)[/tex] is shifted 6 units below which forms the function [tex]g(x)[/tex]
To find the function [tex]g(x)[/tex], we apply the following translation rules:
[tex]f(x)\rightarrow f(x)+c[/tex]
If [tex]c>0[/tex] the function [tex]f(x)[/tex] shifts [tex]c[/tex] units up.
If [tex]c<0[/tex] the function [tex]f(x)[/tex] shifts [tex]c[/tex] units down.
Since the function [tex]f(x)[/tex] is shifting 6 units below, thus value of [tex]c<0[/tex] which is taken as -6.
The translation occurring here is given by:
[tex]f(x)\rightarrow f(x)-6[/tex]
Thus,
[tex]g(x)=f(x)-6[/tex]
Substituting [tex]f(x)=-2x+7[/tex]
[tex]g(x)=-2x+7-6[/tex]
∴ [tex]g(x)=-2x+1[/tex]

Which expression is equivalent to (x^6×x^10/×^-3)^2 and why?
Answer:
The solution for the given expression is [tex]x^{38}[/tex] , i.e option C
Step-by-step explanation:
Given expression as :
[tex](\dfrac{x^{6}\times x^{10}}{x^{-3}})^{2}[/tex]
Now, From the common radix method
∵ In multiplication of radix , if the radix is same , then power is added
I.e [tex]x^{6}\times x^{10[/tex] = [tex]x^{6+10}[/tex]
Or , [tex]x^{6}\times x^{10[/tex] = [tex]x^{16}[/tex]
Now, The expression can be written as
[tex](\frac{x^{16}}{x^{-3}})^{2}[/tex]
And In Division of radix , if the radix is same , then power is subtracted
So, [tex]\frac{x^{16}}{x^{-3}}[/tex]
Or, [tex]x^{16 - (-)3}[/tex]
Or, [tex]x^{16 + 3}[/tex]
or, [tex]x^{19}[/tex]
∴ The expression is now
[tex](x^{19})[/tex]²
Now, again this is written as
[tex]x^{19}[/tex] × [tex]x^{19}[/tex]
I.e here again the radix is same and in multiple for, so, power is added
∴ [tex]x^{19}[/tex] × [tex]x^{19}[/tex] = [tex]x^{19+19}[/tex]
I.e [tex]x^{19}[/tex] × [tex]x^{19}[/tex] = [tex]x^{38}[/tex]
Hence The solution for the given expression is [tex]x^{38}[/tex] , i.e option C . Answer

How does the value of 30,000 x (4 x 3) compare to the value of 300 x (4 x 3)?
Answer:
30,000 x (4 x 3) = 100 times 300 x (4 x 3)
Step-by-step explanation:
Here, the given expressions are:
Expression 1 : 30,000 x (4 x 3)
Expression 2 : 300 x (4 x 3)
Now, simplifying both the expressions, we get
30,000 x (4 x 3) = 30,000 x (12) = 3,60,000
300 x (4 x 3) = 300 x (12) = 3,600
Now, dividing both the expressions, we get:
[tex]\frac{3,60,000}{3,600} = 100[/tex]
or, [tex]\frac{\textrm{Expression 1}}{\textrm{Expression 2}} = 100\\[/tex]
or, {Expression 1} = {Expression 2} x 100
⇒The expression 1 is 100 times the expression 2
Hence, 30,000 x (4 x 3) = 100 times 300 x (4 x 3)
Choose the equation that represents the line passing through the point (2, - 5) with a slope of −3.
y = −3x − 13
y = −3x + 11
y = −3x + 13
y = −3x + 1
Answer:
y = -3x + 1
Step by step (I hope I don't confuse you):
1. First, look for the equation that has a slope of -3. In this case, it's all of them because they all have -3 before the x value.
2. Then look for what's given:
The y of (2, -5) is negative. If the x is 2, that means that the slope has moved down 3 units twice. (-3 is the slope. -3 x 2 is -6.)3. Now see what equation will have -5 when you subtract 6 from it's y intercept.
y = 3x + 11. 11 - 6 is 5, not -5. this one is wrong.y = 3x - 13. -13 - 6 is -19, also incorrect.y = 3x + 1. 1 - 6 is -5, so this is the correct answer.Hope you found this helpful.
The equation of line is y= -3x + 1.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
point (2, - 5) with a slope of −3.
Using slope- intercept form
y = mx + c
-5 = (-3) (2) + c
-5 = -6 + c
c = -5 + 6
c= 1
So, the equation of line is y= -3x + 1

Domain ………
1.9) {(a, b): ab = 12}
Domain ………
Step-by-step explanation:
1.7) x = √y
The square root must be non-negative, so the domain is x ≥ 0, or in interval notation, [0, ∞).
1.8) s = (2r − 5) / (3r)
The denominator can't be 0, so r can't be 0. So the domain is r ≠ 0, or in interval notation, (-∞, 0) (0, ∞).
1.9) ab = 12
Solve for b: b = 12/a
The denominator can't be 0, so a can't be 0. So the domain is a ≠ 0, or in interval notation, (-∞, 0) (0, ∞).

a small appliance manufacturer finds that if the firm produces and sells x blenders
monthly, the total monthly profit P (in dollars) is given by
P(x) = 8x + 0.3x2 - 0.0013x3 - 372.
ne owner wants to produce no more than 225 blenders/month in order to maintain quality
(SLO #1, 2, 6)
a. Find the y-intercept and explain what it means in this context.
Answer:
The y-intercept is - 372 and it means that if the manufacturers do not produce and sell any blenders they will have a loss of $ 372.Explanation:
The polynomial that represents the function is:
[tex]P(x)=8x+0.3x^2-0.0013x^3-372[/tex]Where the variable, x, represents the number of blenders produced and sold monthly, and P(x) is the monthly profit in dollars obtained for the sale of x blenders.
As for the question, the y-intercept is the point on the graph where the function crosses the y-axis, i.e. where the input of the function is x = 0.
Therefore, the y-intercept is the value of the function for x = 0, P(0), and it is found by substituting 0 for x in the polynomial function, which is shown next:
[tex]P(0)=8(0)+0.3(0)^2-0.0013(0)^3-372=-372[/tex]The meaning of this value is that the firm loses $372 when it does not produce and sell any blenders.
