<p style="text-align: justify;">In the given expression, x does not appear, so check the question. As it stands all the terms are constants so the expression has one definite value.</p>
<p style="text-align: justify;">When x is in the denominator of a fraction, the fraction is undefined when x has a value that makes the denominator zero.</p>Other Math Topicshttps://www.mathhomeworkanswers.org/257182/value-of-x-for-which-the-expression-1-42-16-15-is-undefined?show=257184#a257184Sun, 20 Jan 2019 21:34:58 +0000Answered: In the equation +1= 2/x-1, what is the final value of x + √3 ?
https://www.mathhomeworkanswers.org/257181/in-the-equation-1-2-x-1-what-is-the-final-value-of-x-%E2%88%9A3?show=257183#a257183
<p style="text-align:justify">I guess the equation was meant to be x+1=2/(x-1).</p>
<p style="text-align:justify">Multiply both sides by x-1: x²-1=2, x²-1-2=0, x²-3=0=(x-√3)(x+√3).</p>
<p style="text-align:justify">So x+√3=0 is a solution, therefore the value of x+√3 is zero.</p>

What is one possible value of a such that f(a) = g(a)?
https://www.mathhomeworkanswers.org/257133/consider-functions-defined-2and-what-possible-value-such-that?show=257155#a257155
<p style="text-align: justify;">f(a)=4-(a-2)², g(a)=6-a, so 4-(a-2)²=6-a. This can be written (2-a+2)(2+a-2)=6-a, that is, (4-a)a=6-a.</p>
<p style="text-align: justify;">So 4a-a²=6-a, a²-5a+6=0=(a-3)(a-2). So a=3 or 2 (take your pick!).</p>Other Math Topicshttps://www.mathhomeworkanswers.org/257133/consider-functions-defined-2and-what-possible-value-such-that?show=257155#a257155Sat, 19 Jan 2019 14:31:47 +0000Answered: How do I solve 7 4/5 - 3 5/5 in friendliest form?
https://www.mathhomeworkanswers.org/257086/how-do-i-solve-7-4-5-3-5-5-in-friendliest-form?show=257088#a257088
<p style="text-align:justify">Here’s how I would do it. First, did you really mean 3 5/5? I think you might have meant 3⅗ for the second number. That means we have 7⅘-3⅗. We can write this as 7+⅘ minus (3+⅗).</p>
<p style="text-align:justify">First we subtract the whole number parts: 7-3=4, so the whole number part is 4, but we also have to subtract the fractions: ⅘-⅗. This says 4 fifths take away 3 fifths. We know that 4 minus 3 of the same thing leaves one of that thing. In this case, the “thing” is a fifth, so one fifth is the result: ⅕. Now we put the whole number result with it and we have the answer 4+⅕, which we write 4⅕.</p>
<p style="text-align:justify">[If it was supposed to be 3⁵⁄₅, that would be 3+⁵⁄₅=3+1=4 because 5 fifths make 1 whole, so we would subtract 4 from 7⅘ leaving 3⅘, because we subtract the whole numbers first, so that’s 7-4=3. The fraction has nothing to take away from it, so we’re left with what we started with: ⅘. However, in mixed numbers, the top part of the fraction is supposed to be smaller than the bottom part.]</p>

https://www.mathhomeworkanswers.org/257077/find-the-equation-the-line-through-the-point-and-parallel-line?show=257082#a257082
<p style="text-align:justify">y=-4x-4 is another way to write the equation of the line. All lines parallel have the same gradient so y=-4x+a where a is a constant is a way of writing the equation of a parallel line so we have to find a by plugging in the point: -2=-4(-½)+a, -2=2+a, so a=-4 and the equation of the parallel line is y=-4x-4 which is the original line! So the point lies on the original line and 4x+y=-4, 4x+y+4=0 in general form.</p>Other Math Topicshttps://www.mathhomeworkanswers.org/257077/find-the-equation-the-line-through-the-point-and-parallel-line?show=257082#a257082Thu, 17 Jan 2019 14:31:31 +0000Answered: Find the point of intersection and the angle between x - y = 32 and 3x - 8y = 6.
https://www.mathhomeworkanswers.org/257076/find-the-point-of-intersection-and-the-angle-between-32-and-3x?show=257081#a257081
<p style="text-align:justify">y=x-32 and 3x=6+8y is another of writing the equations. So substitute y from the first equation into the second: 3x=6+8(x-32) to give us an equation in one variable only.</p>
<p style="text-align:justify">Therefore, 3x=6+8x-256, 256-6=8x-3x, 250=5x, so x=50 and y=50-32=18. This gives the point of intersection (x,y)=(50,18).</p>
<p style="text-align:justify">To find the angle between the lines, we need their slopes.</p>
<p style="text-align:justify">y=x-32, slope is 1 (ratio of the coefficients); 8y=3x-6, y=⅜x-¾, slope is ⅜.</p>
<p style="text-align:justify">The angles of the slopes are arctan(1)=45° and arctan(⅜)=arctan(.375)=20.56° approx. So the acute angle between the lines is 45-20.56=24.44° approx (angle of intersection).</p>Other Math Topicshttps://www.mathhomeworkanswers.org/257076/find-the-point-of-intersection-and-the-angle-between-32-and-3x?show=257081#a257081Thu, 17 Jan 2019 14:18:40 +0000Answered: Math-25+4h≤50.52

https://www.mathhomeworkanswers.org/257049/what-goes-into-4-5-6-and-7?show=257050#a257050
<p style="text-align: justify;">They have no common factors except 1, which goes into all numbers.</p>
<p style="text-align: justify;">But 4, 5, 6, 7 do share a common multiple, a number they all go into. To find it we split the numbers into pairs. Take the even numbers first: 4 and 6 both go into 12. 4, 6 and 5 go into 5 × 12=60. And now we take 60 and 7 and multiply them together to give us 420. So 4, 5, 6 and 7 all go into 420.</p>Other Math Topicshttps://www.mathhomeworkanswers.org/257049/what-goes-into-4-5-6-and-7?show=257050#a257050Wed, 16 Jan 2019 21:29:50 +0000Answered: analytic and solid geometry

https://www.mathhomeworkanswers.org/256873/what-is-the-unit-price-for-%242-75-per-pound?show=256892#a256892
<p style="text-align:justify">Unit price is the cost of one unit of an item. That unit is a measure of some sort, a weight, a quantity or volume, a length, etc. In this case the unit is weight measured in pounds. The unit price enables us to work out the cost of any amount of the same item. So in this case, 10 pounds would cost 10×2.75=$27.50, and ½lb would cost about 2.75/2=$1.38 (about).</p>
<p style="text-align:justify">In many countries stores are required by law to show the unit price of their goods. For example, a 500-gram packet of cornflakes may show the unit price of a kilogram of cornflakes. Unit price of apples may be shown as the cost per kilogram, so by weighing one or more apples you can work out how much they will cost.</p>
<p style="text-align:justify">You can use the unit price to compare the prices of different sized packages of the same goods, so as to get the best value for your money. Usually, a larger packet will have a lower unit price than a smaller one, because the manufacturer saves a bit on packaging. A store might mark down a larger packet so as to encourage the shopper to buy it instead of a smaller one. Next time you go shopping, check out the unit prices to make sure you’re getting a good deal!</p>Other Math Topicshttps://www.mathhomeworkanswers.org/256873/what-is-the-unit-price-for-%242-75-per-pound?show=256892#a256892Fri, 11 Jan 2019 15:12:54 +0000Answered: What is 1/2 + (-1/3), step by step?

How much juice was purchased
https://www.mathhomeworkanswers.org/247537/bottles-three-gallon-bottles-juice-bottles-juice-purchased?show=256603#a256603
<p style="text-align: justify;">Assuming 16 fluid oz to a pint, 8 fluid oz = 0.5 pint = 1/16 gallon = 0.0625 gallon. 1 quart = ¼gallon = 0.25 gallon. 1.5 quarts = 0.375 gallon.</p>
<p style="text-align: justify;">Total amount of juice = 3×0.375+3×0.5+2×0.0625 = 1.125+1.5+0.125 = 2.75 gallons.</p>Other Math Topicshttps://www.mathhomeworkanswers.org/247537/bottles-three-gallon-bottles-juice-bottles-juice-purchased?show=256603#a256603Wed, 26 Dec 2018 13:02:49 +0000Answered: what is 526.00 broken up into twice a month

<p style="text-align:justify">The point P(-3,-1) is rotated around (-1,3) to Q(-5,5). The picture shows how to find the new coords by rotating the red vector to the blue vector. If you view the vectors as hypotenuses of right triangles, where the legs are the differences between the coords—3-(-1)=4 and -1-(-3)=2—you can see where the P triangle is repositioned to form the Q triangle. Hence you can work out the coords of Q. The right angle for P is 4 units below the point of rotation and 2 units to the left. After rotation, the right angle for Q is 4 units to the left of the point of rotation and 2 units above it. </p>Other Math Topicshttps://www.mathhomeworkanswers.org/256449/point-aftershocks-rotation-degrees-clockwise-about-point?show=256450#a256450Sun, 16 Dec 2018 14:22:27 +0000Answered: Evaluate. 52
