(4 - 7m) - (-n + 2m - 1) pls helppp

Answer:

Step-by-step explanation:

2x + 5y = 7 ......... Equation 1

x = 2 - 4y .......... Equation 2

Substitute x that's equation 2 into equation 1 and solve for y

That's

2( 2 - 4y ) + 5y = 7

4 - 8y + 5y = 7

- 3y + 4 = 7

- 3y = 7 - 4

- 3y = 3

Divide both sides by - 3

y = - 1

Substitute the value of y into equation 1

That's

x = 2 - 4(-1)

x = 2 + 4

x = 6

Therefore the solutions are

Answer:

The answer is "239.62%".

Step-by-step explanation:

Given value:

[tex]\bold{\sin(x)=x- \frac{x^3}{3!}+\frac{x^5}{5!} - \frac{x^7}{7!}+....}[/tex]

Solve the first three values:

[tex]\sin(x)=x- \frac{x^3}{3!}+\frac{x^5}{5!}[/tex]

put the value of sin(4.1):

[tex]\to \sin(4.1)=(4.1)- \frac{(4.1)^3}{3!}+\frac{(4.1)^5}{5!} \\\\[/tex]

                 [tex]=(4.1)- \frac{(4.1)^3}{3!}+\frac{(4.1)^5}{5!} \\\\=(4.1)- \frac{68.92}{3 \times 2\times 1}+\frac{1158.56}{5\times 4 \times 3 \times 2 \times 1}\\\\[/tex]

                 [tex]=(4.1)- 11.48+9.65\\\\= 2.27[/tex]

The actual value of [tex]\sin(4.1) = -1.59[/tex]

Calculating the percentage relative approximate error value:

Formula:

[tex]=\frac{actual \ value - \ approx \ value }{actual \ value} \times 100\\\\[/tex]

[tex]=\frac{-1.59 - 2.27 }{-1.59} \times 100\\\\= \frac{-3.81}{-1.59} \times 100\\\\= \frac{3.81}{1.59} \times 100\\\\=239.62 \ \%[/tex]

Negotiating in trade means you are coming to an agreement on an item's value option (A) is correct.

The goal of negotiation is to obtain an agreement on one or more contentious issues between two or more parties.

As we know,

On the other hand, trade negotiation is a procedure whereby countries come together to talk about the potential for trade with the aim of arriving at a trade agreement.

When you bargain in trade, you're settling on a price for a product.

Thus, negotiating in trade means you are coming to an agreement on an item's value option (A) is correct.

Answer:

m = 2x

Step-by-step explanation:

Simplifying

4x + -2m = 0

Reorder the terms:

-2m + 4x = 0

Solving

-2m + 4x = 0

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-4x' to each side of the equation.

-2m + 4x + -4x = 0 + -4x

Combine like terms: 4x + -4x = 0

-2m + 0 = 0 + -4x

-2m = 0 + -4x

Remove the zero:

-2m = -4x

Divide each side by '-2'.

m = 2x

Simplifying

m = 2x

Answer:

9 1/9 per cousin

Step-by-step explanation:

if the aunt has 58 items to be distributed to 6 cousins, we would set a fraction of 58/6. performing that is 9 with 4/6 left over.

since there is 6 cousins, there will be 2/3 divided by 6 = 2/18, or 1/9

Answer:

  2.60 inches

Step-by-step explanation:

Map and actual distances are proportional. So the map distance m for 30.9 miles will be related to the actual distance in the same way the scale is:

  m/30.9 = 1/11.9

  m = 30.9/11.9 ≈ 2.5967

The length on the map is about 2.60 inches.

Answer:

5 units

Step-by-step explanation:

If point T is on the line segment SU, then ST + TU = SU.

Given

TU = 4x + 1

SU = 8

ST =  3x

To get TU, we need to get the value of x first. To get x, we will substitute the given parameters into the formula;

3x+4x+1 = 8

7x+1 = 8

subtract 1 from both sides

7x+1-1 = 8-1

7x = 7

divide both sides by 7

7x/7 = 7/7

x = 1

Substitute x = 1 into the length TU

Since TU = 4x+1

TU = 4(1)+1

TU = 5

Hence the numerical length of TU is 5 units

Answer:

y = 1/2x + 5

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

When 2 lines are parallel, they have the same slope.

Step 1: Define variables

Random point (2, 6)

m = 1/2

y = 1/2x + b

Step 2: Find b

6 = 1/2(2) + b

6 = 1 + b

5 = b

Step 3: Rewrite parallel linear equation

y = 1/2x + 5

Answer:

k = 7/3

Step-by-step explanation:

Let's first find the equation of line AC. Since point A has an x-coordinate of 0, we know that point A is the y-intercept so when writing the equation of AC in slope-intercept form, we know that b = -2 in y = mx + b (Note that m = slope and b = y-intercept). To find m, we can use points A and C, therefore, m = (0 - (-2)) / (-2 - 0) = 2 / -2 = -1. Now, we know that the equation of line AC is y = -x - 2. To solve for k, we know that point B belongs to AC and that x = -k, y = 5 - 2k in point B, therefore, after plugging those values into y = -x - 2, we get:

5 - 2k = -(-k) - 2

5 - 2k = k - 2

5 - 3k = -2

-3k = -7

k = 7/3
