Answer:

x=lindas age

3 times lindas age (3 time x or 3x) is decreased by 36 (-36), the result (=) is twice lindas age (2 times x or 2x)

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.

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:

D. x^2+3x-1

Step-by-step explanation:

You have:

Amount of money spent per day = $1800

Cost of overhead expenses per day for labor and materials = $9

Selling price of each camera = $18

a. Let us assume the number of cameras manufactured per day = x dollars

Then

Cost of cameras sold in 1 day = 18x

So

18x = 1800 + 9x

18x - 9x = 1800

9x = 1800

x = 200

From the above deduction, we can conclude that the number cameras sold per day is 200

b. Daily selling amount of 250 cameras = 250 * 18

                                                              = 4500 dollars

Daily manufacturing price of 250 cameras = 1800 + (9 * 250)

                                                                   = 4050 dollars

Then

Daily profit = 4500 - 4050

Final answer:

The slope of the line passing through the points (-7,2) and (5,8) is calculated using the slope formula and is found to be 0.5.

Explanation:

The student asked about the slope of the line passing through two points, (-7,2) and (5,8). To find the slope, one should use the slope formula: slope (m) = (y2 - y1) / (x2 - x1). Plugging in the values from the points, we have m = (8 - 2) / (5 - (-7)) = 6 / 12 = 0.5. Therefore, the slope of the line is 0.5.

Answer:

Step-by-step explanation:

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (8, -1) and (2, -5). Substitute:

[tex]m=\dfrac{-5-(-1)}{2-8}=\dfrac{-4}{-6}=\dfrac{2}{3}[/tex]

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

Substitute:

[tex]y-(-1)=\dfrac{2}{3}(x-8)[/tex]

[tex]y+1=\dfrac{2}{3}(x-8)[/tex] → the point-slope form

Convert to the standard form: [tex]Ax+By=C[/tex]

[tex]y+1=\dfrac{2}{3}(x-8)[/tex]        multiply both sides by 3

[tex]3y+3=2(x-8)[/tex]         use the distributive property a(b+c) = ab+ ac

[tex]3y+3=2x-16[/tex]      subtract 3 from both sides

[tex]3y=2x-19[/tex]       subreact 2x from both sides

[tex]-2x+3y=-19[/tex]       change the signs

[tex]2x-3y=19[/tex] → the standard form

W is the total number of oranges.

W/5 is the oranges being divided equally for 5 friends

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.

I am joyous to assist you anytime.

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.

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.

Answer:

4000 units

Step-by-step explanation:

In 2001 the total number of marketed units= 730,000

If this number represents 50% of what was marketed in 2004, then the total number of units marketed in 2004 was:

(100/50)× 730,000=1460000

To get the number for each of the 365 days in 2004 we divide the total for 2004 by 365

1460000/365= 4000 units

Answer: 4,000 units per day.

Step-by-step explanation:

You know that in 2001 its yearly volume was 50% of its volume for 2004.

Therefore, if in 2001 the company marketed 730,000 units of its product, in 2004 the volume is:

[tex]Yearly\ volume_{(2004)}=(730,000\ units)(2)=1,460,000\ units[/tex]

Let be "x" the number of units for each of the 365 days of 2004, you can find its value by dividing  the 2004 volume by 365.

The result is:

[tex]units=\frac{1,460,000\ units}{365}=4,000\ units.[/tex]

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.
