Step-by-step explanation:

To solve for the two numbers that sum to -102, with one number being 62 less than the other, we use algebraic methods to find the numbers as -20 and -82.

To find the two numbers that sum to -102 and where one number is 62 less than the other, we can set up the following system of equations based on the given information:

Substitute y from the second equation into the first equation:

Now that we have x, we can find y by substituting x back into the equation y = x - 62:

Therefore, the two numbers are -20 and -82.

Answer:

f(2k)=0

Step-by-step explanation:

Let's suppose f(x) is such that (x-2k) is one of its factors. We can write it as

f(x)=(x-2k).g(x)

Where g(x) is any other function of x, and g(x) in non-divisible by (x-2k). If we replace x=2k into f, we get

f(2k)=(0).g(2k)=0

f(2k)=0

Step-by-step explanation:

took the test

The point located 3/5 of the way from point A(4, 5) to point B(-6, 0) on line segment BA is at (0, 3). This is found using the formula for division of a line segment at given ratio.

The subject of this question is Geometry, specifically finding the coordinates of a point along a line segment. Line segment BA has coordinates B(-6, 0) and A(4, 5). To find the point located 3/5 of the way from point A to point B, we will need to use the formula for the division of a line segment which is: X = x1 + r(x2 - x1) and Y = y1 + r(y2 – y1), where r is the ratio, in this case 3/5.

Using the formula, the x coordinate of the point can be calculated as: X = (-6) + 3/5 [(4) - (-6)] = -6 + 3/5 * 10 = -6+6 = 0. The y coordinate of the point can be calculated as: Y = 0 + 3/5 [(5) - 0] = 0 + 3 = 3. Therefore, the point is at (0,3) which is located 3/5 of the way from point A to point B on the line segment.

Final answer:

The coordinates of the point located 3/5 of the way from point A to point B are (0, 3), calculated by finding the weighted average of the x and y coordinates of the endpoints.

Explanation:

To find the coordinates of the point located 3/5 of the way from point A to point B, we need to calculate the weighted average of the endpoints. The coordinates of point B are (-6, 0) and the coordinates of point A are (4, 5).

The x-coordinate of the point is calculated as follows:
(-6) + ((4 - (-6)) × (3/5)) = (-6) + (10 × (3/5)) = (-6) + 6 = 0.

The y-coordinate of the point is calculated as follows:
0 + ((5 - 0) × (3/5)) = 0 + (5 × (3/5)) = 3.

Therefore, the coordinates of the point located 3/5 of the way from point A to point B are (0, 3).

Answer:

The value of x is 25.

Step-by-step explanation:

Given:

side AB = [tex]3x-5[/tex]

side BC = [tex]2x+20[/tex]

side AC = [tex]4x-30[/tex]

In Δ ABC is an equilateral triangle.

In equilateral triangle all three angles are same and also the sides are same.

Hence side AB = side BC

Substituting the values for side AB and side BC we get,

[tex]3x-5=2x+20\\3x-2x=20+5\\x=25[/tex]

Hence the value of x = 25.

From Given figure :

Sin angle = [tex]\dfrac{\textrm perpendicular}{\textrm Hypotenuse}[/tex]

or ,  Sin C =  [tex]\dfrac{\textrm 3x - 5}{\textrm 4 x - 30}[/tex]

Cos angle =  [tex]\dfrac{\textrm Base}{\textrm Hypotenuse}[/tex]

To have $18,000 in 2 years with a 20% annual interest rate compounded continuously, you need to invest approximately $12,065.76.

To determine the amount of money you need to invest to have $18,000 in 2 years with a 20% annual interest rate compounded continuously, we can use the formula:

A = P * e^(rt)

Where:

Substituting the values into the formula:

18,000 = P * e^(0.20*2)

Simplifying:

18,000 = P * e^(0.40)

P = 18,000 / e^(0.40)

Using a calculator to evaluate the exponential term:

P ≈ 12,065.76

Therefore, you need to invest approximately $12,065.76 to have $18,000 in 2 years.

Answer:

x = -1

Step-by-step explanation:

Let's solve your equation step-by-step.

7x + 12 = 2(1 − x) − x

Step 1: Simplify both sides of the equation.

7x + 12 = 2(1 − x) − x

7x + 12 = (2) (1) + (2) (− x) + − x (Distribute)

7x + 12 = 2 + − 2x + − x

7x + 12 = (− 2x + − x) + (2) (Combine Like Terms)

7x + 12 = − 3x + 2

7x + 12 = − 3x + 2

Step 2: Add 3x to both sides.

7x + 12 + 3x = − 3x + 2 + 3x

10x + 12 = 2

Step 3: Subtract 12 from both sides.

10x + 12 − 12 = 2 − 12

10x = − 10

Step 4: Divide both sides by 10.

10x/10 = - 10/10

x = - 1

Answer:

- 2 < x < 4

Step-by-step explanation:

We have to write in interval notation of the following interval.

The interval is given by (-2,4) which means the values of the variable, say x, vary from -2 (but not including -2) to 4 (but not including 4).

So, in interval notation this can be written as - 2 < x < 4 (Answer)

Therefore, the values -2 and 4 are the limiting end values of the variable x.

Answer:

n= Total number of packages on trucks= 6096

n = T x P (Model Equation)

Step-by-step explanation:

No. Of delivery trucks = T = 127

Package on each truck = P = 48

Total number of packages on trucks =n= ?

Each truck contains 48 packages and total trucks were 127, to find total number of packages on trucks , we just need to multiply the number of trucks with the number of package on each truck.

Total number of packages on trucks =n= (No. Of delivery trucks) x (Package on each truck)

n = T x P (Model Equation)

n= 127 x 48

n= 6096 (Total number of packages on trucks)

Answer:

1/0.04 = 25

Step-by-step explanation:

Answer:

Step-by-step explanation:

well 1/4% wouldnt be 25% because they are 25% = 0.25 = 1/4

the percentage sign changes everything

since it is 1/4% rather than 1/4 by itself

1/4% = 0.25%

if you want to know the percent as a decimal you move the "." to the left twice

(or divide by 100)

so that means that the decimal of 0.25% would be 0.0025

Answer:

C(-4,-2), D(3,-7)

[tex]Ar=35unit^{2}[/tex]

Step-by-step explanation:

we procced to identify points:

A(-4,-7), B(3,-2)

for being the sides of a rectangle parallel to the axes, we find the other two vertices (VIEW GRAPH)

C(-4,-2), D(3,-7);  Area of the rectangle Ar=b*h, where

[tex]b=(X_{D}-X_{A}); h=(Y_{B}-Y_{D})[/tex]

So Ar=(3-(-4))*(-2-(-7)) = (3+4)*(-2+7)=7*5=[tex]35unit^{2}[/tex]

Final answer:

The other two vertices of the rectangle are (3, -7) and (-4, -2), and the area of the rectangle is 35 square units.

Explanation:

To find the coordinates of the other two vertices of a rectangle given two vertices on the coordinate plane, use the fact that the sides of the rectangle are parallel to the axes.

The two given vertices are (3, -2) and (-4, -7). A rectangle has opposite sides of equal length, so the x-coordinates of the opposite vertices must be the same for one pair, and the y-coordinates must be the same for the other pair. Therefore, the other two vertices will have coordinates (3, -7) and (-4, -2).

To find the area of the rectangle, calculate the difference in the x-coordinates (length) and the difference in the y-coordinates (width), then multiply these together.

The length is |3 - (-4)| = 7 and the width is |-2 - (-7)| = 5,

so the area is 7 × 5 = 35 square units.

Answer:

For more than 500 minutes

Step-by-step explanation:

Let x be the number of minutes.

First company charges:

$0.029 per minute, then $0.029x for x minutes

and a $2 monthly fee.

In total, $(0.029x+2)

Second company charges:

$0.033 per minute, then $0.033x for x minutes

with no monthly fee.

If the charges for the first company are cheaper, then
