Answer:

1.)   B

2.)  (7,1)

3.)  (-8,12)

(-7,+6)

Step-by-step explanation:

Answer:   - (2 + 3) = -5

Step-by-step explanation:

When combining numbers that have the same sign, you add them and then include the sign.

For example:

-2 - 3 = -(2 + 3) = -5

-6 - 5 = -(6 + 5) = -11

-7 - 8 = -(7 + 8) = -15

Answer:

Step-by-step explanation:

Since we know the line goes through points [tex](8,9)[/tex] and [tex](2,4)[/tex], we can construct a line in slope-intercept form

[tex]y = mx + b[/tex]

where [tex]m[/tex] is the slope and [tex]b[/tex] is the Y-intercept.

The slope can be found using the two points provided:

[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

[tex]\frac{9 - 4}{8 - 2}[/tex]

[tex]\frac{5}{6}[/tex]

The line is now represented as

[tex]y = \frac{5}{6}x + b[/tex]

To solve for [tex]b[/tex], we can plug in one of the two points:

[tex]y = \frac{5}{6}x + b[/tex]

[tex](9) = \frac{5}{6}(8) + b[/tex]

[tex]4 = \frac{20}{3} + b[/tex]

[tex]b = \frac{-8}{3}[/tex]

We know have our line:

[tex]y = \frac{5}{6}x - \frac{8}{3}[/tex]

To determine if the point [tex](-4, 3)[/tex] falls on this line, we just plug the numbers into the equation and see if it holds true:

[tex]y = \frac{5}{6}x - \frac{8}{3}[/tex]

[tex](3) = \frac{5}{6}(-4) - \frac{8}{3}[/tex]

[tex]3 = \frac{-10}{3} - \frac{8}{3}[/tex]

[tex]3 = \frac{-18}{3}[/tex]

[tex]3 = -6[/tex]

This does not hold true, so the point is not on the line.

Answer:

a. Rate: the percent that interest is paid annually as a decimal.                                                                                                                                                                                                explanation:In the given formula  of simple interest I = P.r.t

P is the principal or initial amount.

r is the rate of interest paid annually as a decimal.

t is the time period in years.

The simple interest formula permits us to calculate I, which is the interest charged or earned on a loan.

|7-10| = 3 (absolute value), then multiply to the negative sign. answer:-3

Answer:

Step-by-step explanation:

4.13*1000=4130

Because you move the decimal to the right 3 times'

413000/100=4130

Move the decimal 2 times to the left

The statement [tex]""4.13 x 1000 = 4130[/tex] and [tex]413,000/100 = 4130[/tex]"" is true due to the rules of multiplication and division with powers of ten.

 Firstly, when multiplying a number by 10 raised to a power, the decimal point in the number moves to the right as many places as there are zeros in the power of ten. In this case, 4.13 is being multiplied by [tex]10^3[/tex] (which is 1000). The decimal point in 4.13 moves three places to the right, resulting in 4130. This is because [tex]10^3[/tex] means [tex]10 x 10 x 10,[/tex] and each multiplication by 10 moves the decimal point one place to the right.

 Secondly, when dividing a number by 10 raised to a power, the decimal point in the number moves to the left as many places as there are zeros in the power of ten. Here, 413,000 is being divided by [tex]10^2[/tex] (which is 100). The decimal point in 413,000 moves two places to the left, resulting in 4130. This is because [tex]10^2[/tex] means [tex]10 x 10[/tex], and each division by 10 moves the decimal point one place to the left.

 Therefore, both parts of the statement are true:

- [tex]4.13 multiplied by 10^3 (1000) equals 4130.[/tex]

- [tex]413,000 divided by 10^2 (100) equals 4130.[/tex]

 In summary, the operations performed on the numbers are consistent with the rules for manipulating decimal numbers when multiplying or dividing by powers of ten.

Answer:

1/100

Step-by-step explanation:

7 in 3.47 is 7/100

7 in 7.34 is 7

so the first 7 is 1/100 times the value of 7

Hello.

Here is the step-by-step

(32-5) + (3*4-2) ---> 27 + (3*4-2)

27 + (3*4-2) ---> 27 + (12-2)

27 + (12-2) ---> 27 + 10

27 + 10 ---> 37

You have to work inside the parenthesis, left to right, then solve.

The result of (32 - 5) + (3 * 4 - 2) is 37.

Begin by solving the operations inside each set of parentheses separately.

For the first parentheses:

32 - 5 = 27

For the second parentheses, calculate the multiplication first before the subtraction:

3 * 4 = 12

Then subtract 2:

12 - 2 = 10

Combine the results: Add the results of the two parentheses together:

27 + 10

Perform the addition:

27 + 10 = 37

Answer:

n=-5

Step-by-step explanation:

Line through (5, -3) and (-2, 9)

The slope is (9 - -3) / (-2 - 5) = -12/7

Point slope form, point (a,b), slope m, is

y - b = m(x-a)

When we pick the point (a,b)=(5,-3) our answer is

y + 3 = -12/7 (x - 5)

That's almost D except for the sign on the slope.  The slope is definitely negative so none of the above is correct.

Answer:

17.

Step-by-step explanation:

1. Plug in 7 for x.

2. 3(7)-4

3. 3 times 7 is 21.

4. 21 minus 4 is 17.

5. The Answer is 17.

Answer:

12

Step-by-step explanation:

28 / 4 = 7

1) -2

2) -2+7=5

3) 5+7=12

4) 12+7=19

5)19+7=26

When moving in equal steps from -2 to 26 over four steps, each step increases the value by 7. Therefore, after two steps from -2, the third number you reach is 12.

The question is about stepping evenly or moving in equal intervals from an initial number. Given that the first number is -2 and the fifth number is 26, we need to determine what the third number would be. Taking -2 being the first and the fifth being 26 means there are 4 steps between them. To find the equal steps between, you need to subtract -2 from 26 and divide by 4 (the steps in between), which gives you 7. This means each step increases the value by 7. Therefore, the first number is -2, the second number is -2+7 = 5, and third number is 5+7=12.

Step-by-step explanation:

The system of equations is: [tex]\( x + y = 13 \)[/tex] and [tex]\( 200x + 350y = 3050 \)[/tex], where \( x \) represents the number of cans of soup purchased and \( y \) represents the number of frozen dinners purchased.

Let's define:
- \( x \) as the number of cans of soup purchased.
- \( y \) as the number of frozen dinners purchased.

The system of equations would be:

1.[tex]\( x + y = 13 \)[/tex] (since Savannah purchased a total of 13 cans of soup and frozen dinners)
2.[tex]\( 200x + 350y = 3050 \)[/tex] (since each can of soup has 200 mg of sodium and each frozen dinner has 350 mg of sodium, and together they contain 3050 mg of sodium).

Answer:

$347,600

Step-by-step explanation:

There is fixed startup cost of 242,000 no matter how many units they product.

Also, each unit costs 6 to produce, so to produce 17,600 items, it's going to cost:

17,600 * 6 = 105,600

Along with this the fixed startup cost of 242,000, would make total cost:

Total cost = 242,000 + 105,600 = $347,600

To find the total cost of producing 17,600 items with a production cost of $6 per item and $242,000 in start-up costs, the correct formula ($6 \times 17,600) + $242,000 must be used, yielding a total cost of $347,600.

The given expression for the total cost to produce q products appears to be incomplete. Based on the initial information provided, the cost to produce each item is $6, and there are start-up costs of $242,000. If we correct the expression, it should be $6q + $242,000 to find the total cost for producing q items. Thus, to calculate the cost to produce 17,600 items, we use the correct formula:

Total Cost = ($6 \times 17,600) + $242,000

Performing the calculations:

Total Cost = ($105,600) + $242,000

Total Cost = $347,600

Therefore, it will cost the company $347,600 to produce 17,600 items.

Answer:

Dimensions are

Length= 91 units

Width=15 units

Step-by-step explanation:

The formula for perimeter is 2(l+w) where l is length and w is width.

Given perimeter is 212 units

Let the width , w=x units

Length is 16 more 5 times the width= 5x+16 units

So length  will be = 5x+16

and width will be= x

Perimeter = 2(l+w)

212=2( 5x+16+x)

212=10x+32+2x

212=12x+32

212-32=12x

180=12x

180/12=12x/12

15=x----------------------width

For length= 5x+16

l=(5*15) +16

l=75+16=91 units-------------length

Let

x ----> the length of one leg of the triangle

we know that

In the right isosceles triangle of the figure

The cosine of angle of 45 degrees is equal to the adjacent side to angle of 45 degrees divided by the hypotenuse

[tex]cos(45\°)=\frac{x}{22\sqrt{2}}[/tex] ---> equation A

[tex]cos(45\°)=\frac{\sqrt{2}}{2}[/tex] ----> equation B

equate equation A and equation B and solve for x

[tex]\frac{x}{22\sqrt{2}}=\frac{\sqrt{2}}{2}[/tex]

[tex]x=\frac{\sqrt{2}}{2}(22\sqrt{2})=22\ units[/tex]

therefore

The length of one leg of the triangle is 22 units
