Answer:

[tex]-y^{2}-4yi+4[/tex]

Step-by-step explanation:

we know that

[tex](a-b)^{2}=a^{2}-2ab+b^{2}[/tex]

we have

[tex](2-yi)^{2}[/tex]

substitute

[tex](2-yi)^{2}=(2)^{2}-2(2)(yi)+(yi)^{2}[/tex]

[tex](2-yi)^{2}=4-4yi+(y^{2})(i^{2})[/tex]

Remember that

[tex]i^{2}=-1[/tex]

substitute

[tex](2-yi)^{2}=4-4yi+(y^{2})(-1)[/tex]

[tex](2-yi)^{2}=4-4yi-y^{2}[/tex]

[tex](2-yi)^{2}=-y^{2}-4yi+4[/tex]

Answer:

Part a)  In order to solve the equation, we will simplify both of them.  Once we do that, if we notice, they are the same equation, so therefore, if x=10, then we will be able to match the equation.

Part b) The reason the expressions are not equal when x=-1/2 is because if we see, that in the second expression, 2x^2, if x=-1/2, then the answer becomes -1, and we eventually end up with 1.

Part c)  As we can see, the expressions are the same, so if x is any number other than -1/2, then we will be able to show that the expressions are equal.

Step-by-step explanation:

By the way, this question is from the Art of Problem Solving, and you should not just copy answers or copy of them.

Part (a)  We shall simplify both of them in order to find the solution to the equation.

Part (b)  When x=-1/2, the answers to the second expression, 2x2, change to -1, and we eventually arrive in 1.

Part (c)  As we can see, the expressions are identical, thus we can demonstrate that they are equal if x is any number other than -1/2.

Answer:

x = -80

Explanation

-40 divided by 1/2 is -80

Answer:

x = 9/7

Step-by-step explanation:

-5/4x-5 =-35

-5 = -35 * (4x-5)  

-5 = -35*4x - 5*(-35)

-5 = - 140x + 175

- 140x + 175 = -5

-140x = -5 - 175 = -180

x = -180 / -140 =18 / 14 = 9 /7

To solve the given equation, -5/4x = -35, for x, you multiply both sides by the reciprocal of -5/4 which is -4/5. This gives you x = 28 as the solution.

The given equation in your question is -5/4x = -35. In order to solve this equation for x, you would first want to isolate x on one side of the equation. Thus, we'll need to divide both sides of the equation by -5/4.

However, dividing by a fraction is the same as multiplying by its reciprocal. So, in this case, we'll multiply both sides by -4/5, which is the reciprocal of -5/4. This gives us:

x = (-35) * (-4/5)

Doing the multiplication results in x = 28.

Therefore, the solution for x in the equation is 28.

Time= distance/speed (T = d/s)

Rate or speed are similar since they both represent some distance per unit time such miles per hour and kilometers per hour. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

distance = rate x time To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

This is because, speed of the object refers distance travelled divided by time or it expressed as, Furthermore, 1 could also explain the relationship of the time with other two variables using this formula. Speed could be of 2 types, relative or average.

from the formula,

Answer:

y = 6x + 1

Step-by-step explanation:

linear equations (straight line) are expressed in the following general form:

y = mx + b, where m is the gradient and b is the y-ordinate of the point where the line crosses the y-axis (called the y-intercept)

Given : m = 6

we realize that point (0,1) is actually on the y-axis (i.e x=0), therefore this is coincidentally the y-intercept. Hence b = 1

Therefore the whole equation is

y = 6x + 1

The equation for a line is:

y = mx + c

Note:

y  is the y coordinate

m is the slope

x is the x coordinate

c is the y -intercept (where the line crosses the y-axis.

The question tells us that the slope is 6 (so m is 6)

It also tells that the coordinates are: (0 , 1)    (so x is 0    and y is 1)

Lets plug in these values into the equation and solve to get the missing value ( which is c) :

y = mx + c

1 = 6(0) + c

1 = c.

Now to get the equation of the line, we plug in the values for m and c into y= mx + c:

Equation of line: y = 6x + 1

Answer:

Equation of line with slop m = 6 and including point (0, 1) is:

y = 6x + 1

Using Hooke's Law, the spring would stretch a total of 19.5 cm when 13 washers are placed on it.

To find out how much a spring would elongate when the number of washers is increased, we use Hooke's Law, which describes linear elasticity.

Since it is given that 3 washers cause the spring to stretch 4.5 cm, we can assume that each washer causes an equal amount of stretch under this elastic limit. Therefore, the amount of stretch per washer is 4.5 cm divided by 3, which is 1.5 cm per washer.

If you hang 13 washers on the spring, the total stretch can be calculated by multiplying the amount of stretch per washer with the total number of washers:

Stretch per washer × Number of washers = Total stretch

1.5 cm/washer × 13 washers = 19.5 cm.

So, with 13 washers, the spring would stretch a total of 19.5 cm.

Therefore we can use the the x and y coordinates from the points given, (-3,0) and (2,7) to calculate the slope.

m= (7-0)/(2-⁻3)

Slope= 7/5

Answer: B

Step-by-step explanation:

Answer:

33.7 degrees

Step-by-step explanation:

As we go from (3,7) to (6,9), x increases by 3 and y increases by 2.  Thus, the gradient (slope) of the line connecting these two points is

m = rise / run = 2/3.  Using the slope-intercept formula y = mx + b, we obtain

7 = (2/3)(3) + b, or 7 = 2 + b, so we see that b = 5 and y = (2/3)x + 5.  The y-intercept is (0, 5).

Next we find the x-intercept.  We set y = (2/3)x + 5 = to 0 and solve for x:

(2/3)x = -5, or (3/2)(2/3)x = -5(3/2), or x = -15/2, so that the x-intercept is

(-15/2, 0).  This line intersects the x-axis at (-15/2, 0).

Now look at the segment of this line connecting (-15/2, 0) and (0, 5).  Here x increases by 15/2 and y increases by 5, and so the tangent of the acute angle in question is

tan Ф = 5 / (15/2) = 10 / 15 = 2/3.

Using the inverse tangent function, we get Ф = arctan 2/3, or approx.

33.7 degrees.

I believe you meant "the acute angle it makes with the positive x-axis."​

Final answer:

The gradient of the line is 2/3, and the acute angle it makes with the positive x-axis is found by taking the arctan of the gradient. which is approximately 33.69 degrees.

Explanation:

The gradient of the line joining two points, (x1, y1) and (x2, y2), is calculated using the formula:
Gradient = (y2 - y1) / (x2 - x1)

Substituting the given points (3,7) and (6,9) into the formula, we get:

Gradient = (9 - 7) / (6 - 3) = 2 / 3

The gradient is 2/3. To find the acute angle θ the line makes with the positive x-axis, we use the formula:
Tan(θ) = Gradient

So, θ = arctan(Gradient)

θ = arctan(2/3)

Calculating θ will give us the acute angle. which is approximately 33.69 degrees.

Final answer:

To solve x² - 12x + 36 = 90 for x, we simplify the equation to x² - 12x - 54 = 0 and use the quadratic formula to find x = 6 + 3√10 and x = 6 - 3√10.

Explanation:

To solve the equation x² - 12x + 36 = 90, we can first simplify it by subtracting 90 from both sides to set it equal to zero:

Now we use the quadratic formula, which states that for any quadratic equation of the form ax² + bx + c = 0, the solutions for x can be found using:

Applying this to our equation with a = 1, b = -12, and c = -54, we get:

Thus, the solutions are x = 6 + 3√10 and x = 6 - 3√10.

 Applying this property, we know that:

[tex]\sqrt{\frac{25x^9y^3}{64x^6y^{11}} }=\sqrt{\frac{25x^3}{64y^8}}[/tex]

Descompose 25 and 64 into their prime factors:

[tex]25=5*5=5^2\\64=8*8=8^2[/tex]

Since:

[tex]\sqrt[n]{a^n}=a[/tex]

And according to the Product of powers property:

[tex](a^m)(a^n)=a^{(m+n)}[/tex]

You can simplify. So, the equivalent expression is:

now we have

3x-36=2x

subtract 2x

x-36=0

add 36

x=36

age=36

Step-by-step explanation:

Using algebra to solve the problem, we create the equation L - 36 = 2L, representing Linda's age. Solving for 'L', we find that Linda is 36 years old.

This problem can be solved by using algebra, a branch of mathematics. Let's assume that Linda's age is denoted by the variable 'L'. According to the problem, if Linda's age is decreased by 36, the result is twice Linda's age. We can write this as an equation: L - 36 = 2L.

In order to solve for 'L', we'll need to get all terms involving 'L' on one side of the equation. We would then subtract 'L' from both sides, giving us -36 = L, or, re-arranged, L = 36. Therefore, Linda is 36 years old.
