<p style="text-align: justify;">A slope of 2 means we must have y=2x+... because the coefficient of x divided by the coefficient of y must be 2.

<p style="text-align:justify">The picture shows all 36 outcomes of rolling two dice. The table body shows the difference between the values of the dice for every possible combination. The difference of 2 is highlighted in red, so there are 8 with a difference of 2, meaning that there are 36-8=28 with a difference of not-2. Therefore the probability is 28/36=7/9.</p>

https://www.mathhomeworkanswers.org/261452/need-real-example-situation-would-following-order-operations?show=261468#a261468
<p style="text-align:justify">Borrowing money is an everyday occurrence, for example, borrowing from a bank to buy an expensive item like a house or a car. Lenders probably use tables to find out what the monthly repayment will be over a period of years. Lenders will charge borrowers interest, usually compound interest, because that brings more money in! The tables are constructed from a formula, which could be the one shown here. The algebraic equation for calculating the monthly repayment, m, of an amount, A, over t years at a monthly compound rate of r% is:</p>
<p style="text-align:justify">m=rA/(100(1-(1+r/100)^-12t)).</p>
<p style="text-align:justify">This may look frightening but it still has to follow PEMDAS or BODMAS rules for order of operation.</p>
<p style="text-align:justify">Let’s break it down. There are parentheses (P), an exponent (E), multiplication (M), division (D), addition (A) and subtraction (S). </p>
<p style="text-align:justify">P: There are three sets of parentheses. The innermost is (1+r/100), so this calculation must be done first. And within the parentheses we have addition (A) and division (D). Division takes place before addition. Let’s say that r=0.5%. Divide by 100 to get 0.005. So we have 1+0.005=1.005.</p>
<p style="text-align:justify">E: Having calculated the contents of the parentheses, we see there’s an exponent -12t. This contains multiplication, which must be done first before we can know what the exponent is. Suppose t=20 years, then 12t=240 (years converted to months). There is a unary operator minus in front of 12t, which tells us to make 240 into negative 240, -240. We have enough now to do the calculation 1.005^-240. This is a job for a calculator and it comes to 0.3021 approximately.</p>

<ol>
<li style="text-align: justify;">If element x belongs to set B and set A, the intersection A∩B also contains x. Not B (complement) does not contain x, so the intersection with A does not contain x.</li>
<li style="text-align: justify;">If x does not belong to set B but does belong to set A, A∩B does not contain x, but since not B does, its intersection with A contains x.</li>
<li style="text-align: justify;">If x does not belong to set A, then neither intersection contains x.</li>
<li style="text-align: justify;">If we consider the union of the two intersections from 1 and 2 above, x belongs to the union in each case.</li>
<li style="text-align: justify;">For 3 above, the union does not contain x.</li>

https://www.mathhomeworkanswers.org/261318/possible-solve-every-quadratic-equation-factoring-why-why?show=261331#a261331
<p style="text-align:justify">The answer can be yes or no depending on what you mean by factoring. If you mean using normal (real) numbers the answer is no; if you want to include complex numbers (which have an imaginary component) the answer is yes. I assume you mean ordinary numbers. Every quadratic can be graphed. It’s a parabola. If the parabola intersects the x axis, then it can be factorised. If it sits above or below the x axis it can’t be factorised. This is because the x intercepts are the zeroes of the quadratic and the zeroes are directly related to the factors.</p>
<p style="text-align:justify">Another meaning to factorisation is whether the factors are irrational or rational, that is, do they contain a square root? If they do, you may want to reject them as factors because irrationals cannot be precisely defined as “normal” numbers, so the answer is no, the quadratic can’t be solved. If they don’t contain square roots, the answer is yes, the quadratic can be solved.</p>
<p style="text-align:justify">Is every quadratic factorisable? Simple answer, no, if you stick with simple numbers, avoid irrationals, avoid complex numbers.</p>Algebra 1 Answershttps://www.mathhomeworkanswers.org/261318/possible-solve-every-quadratic-equation-factoring-why-why?show=261331#a261331Thu, 16 May 2019 09:38:52 +0000Answered: 15p +3p^2 - 4p + 7p^2

https://www.mathhomeworkanswers.org/79289/how-do-you-work-out-121r-2-64t-2?show=261316#a261316
There is no greatest common factor, however Both 121 and 64 are perfect squares, so you can factor it down to (11r)^2 - (8t)^2, which can then factor down to (11r-8t)^2 which factors to (11r-8t)(11r+8t).

https://www.mathhomeworkanswers.org/72713/what-is-a-horizontal-asymptote?show=261313#a261313
<p style="text-align:justify">The horizontal asymptote is determined by considering large values of x. 10x/(8x²+1) becomes 10x/8x²=5/(4x). This approaches zero as the magnitude of x gets very large, positive or negative, so the horizontal asymptote is y=0, the x-axis.</p>Algebra 1 Answershttps://www.mathhomeworkanswers.org/72713/what-is-a-horizontal-asymptote?show=261313#a261313Wed, 15 May 2019 19:23:50 +0000Answered: Find the range of the given data set. -4, -3, -1, -1, 0, 1 -5 -3 3 5

https://www.mathhomeworkanswers.org/261233/find-new-equation-to-triple-the-solution-for-sin-25-domain-2pi?show=261234#a261234
<p style="text-align:justify">The solution is x=arcsin(0.25), so we need to find an equation with the solution 3arcsin(0.25).</p>
<p style="text-align:justify">So x/3=arcsin(0.25) and sin(x/3)=0.25.</p>
<p style="text-align:justify">sin(x)=sin(2x/3+x/3)=sin(2x/3)cos(x/3)+cos(2x/3)sin(x/3)=0.25.</p>
<p style="text-align:justify">2sin(x/3)cos²(x/3)+(1-2sin²(x/3))sin(x/3)=0.25.</p>
<p style="text-align:justify">2sin(x/3)(1-sin²(x/3))+sin(x/3)-2sin³(x/3)=0.25.</p>
<p style="text-align:justify">3sin(x/3)-4sin³(x/3)=0.25. This cubic equation needs to be solved for x/3.</p>
<p style="text-align:justify">It can be written 16sin³(x/3)-12sin(x/3)+1=0.</p>
<p style="text-align:justify">If y=x/3, 16sin³y-12siny+1=0 is an equation with the required solution given by y.</p>
<p style="text-align:justify">x=arcsin(0.25)=0.25268 or 2.88891 approx, so y=x/3=0.084227 or 0.96297, siny=<a href="denied:tel:0.0841272" rel="nofollow">0.0841272</a> or 0.820892 which is a solution of the cubic.

(09.02 HC) The function f(x) = −x2 + 44x − 384 Part B: Determine the x-intercepts. What do these values mean in the context of the problem? (5 points)
https://www.mathhomeworkanswers.org/261190/function-determine-intercepts-values-context-problem-points?show=261191#a261191
<p style="text-align:justify">f(x)=-x²+44x-484+484-384=100-(x-22)².</p>
<p style="text-align:justify">Part A: The vertex is the maximum point of f(x), and this occurs when x=22, when f(x)=100. This means that the maximum profit is $100 when 22 donut combos are sold.</p>
<p style="text-align:justify">Part B: f(x)=100-(x-22)²=(10-(x-22))(10+(x-22)). So f(x)=(32-x)(x-12), and the x intercepts are 32 and 12. This means that there is break even (neither profit nor loss) when 32 or 12 donut combos are sold. Note that the maximum profit occurs at the average of these two quantities—(32+12)/2=44/2=22. The x intercepts are symmetrical, being 10 donut combos on each side of the axis of symmetry.</p>Algebra 1 Answershttps://www.mathhomeworkanswers.org/261190/function-determine-intercepts-values-context-problem-points?show=261191#a261191Sun, 12 May 2019 20:28:05 +0000Answered: what is 45 divided by 7?

<p style="text-align: justify;"> We know the derivative of eˣ is eˣ.</p>
<p style="text-align: justify;">If we write eˣ=a₀+a₁x+a₂x²+...+a_nx^n</p>
<p style="text-align: justify;">When x=0, 1=a₀.</p>
<p style="text-align: justify;">Now differentiate:</p>
<p style="text-align: justify;">eˣ=a₁+2a₂x+...+na_nx^(n-1)</p>
<p style="text-align: justify;">and put x=0:</p>
<p style="text-align: justify;">1=a₁.</p>
<p style="text-align: justify;">Differentiate again:</p>
<p style="text-align: justify;">eˣ=2a₂+...n(n-1)x^(n-2).</p>
<p style="text-align: justify;">When x=0, 1=2a₂.</p>
<p style="text-align: justify;">If we repeatedly differentiate, and put x=0 to solve for a_n, we end up with the series:</p>
<p style="text-align: justify;">1+x+x²/2!+x³/3!+...+x^n/n! to infinity.</p>
