Answer:Domestic Stamps: 123

Foreign Stamps: 89

Step-by-step explanation:

So we have two equations

x - y = 34

x + y =212

Let's take the first equation and put it in terms of x

x-y+y= 34+y

x= 34 + y

Now that we have a value for x, substitute it into the second equation for x and solve for y.

(34+y)+y=212

34+y+y = 212

34+2y= 212

34-34+ 2y=212-34

2y= 178

2y/2=178/2

y= 89

Now that we know the value for y, we can substitute it into the first equation and solve for x.

x-89=34

X-89+89=34+89

X=123

Y= 89

X =123

ANSWER

Domestic Stamps: 123

Foreign Stamps: 89

Answer:

b(n) = 15 - 7(n - 1)

Step-by-step explanation:

15 is the y-intercept

-7 is the slope

Answer:

[tex]a_{n}[/tex] = 22 - 7n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

8 - 15 = 1 - 8 = - 7

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 15 and d = - 7 , then

[tex]a_{n}[/tex] = 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

D.

Step-by-step explanation:

That is the answer. The complex numbers have opposite real parts.

Answer:

i would say

y = ( 77 - x ) / 2

Step-by-step explanation:

2x + 4y = 123 + 31

2x +4y = 154

4y = 154 -2x

y = ( 154 - 2x ) / 4

y = ( 77 - x ) / 2

Answer:

The equation in slope-intercept form through the point (4, -1) and is perpendicular to the line y = x + 2 is: y=-x+3

Step-by-step explanation:

Given equation of line is:

[tex]y = x+2[/tex]

Comparing it with the general form of equation of line in slope-intercept form

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

The slope of given line is 1 as the co-efficient of x in the equation is 1.

When two lines are perpendicular, the product of their slopes is -1

Let m1 be the slope of new line

Then

[tex]m.m_1 = -1\\1.m_1 = -1\\m_1 = -1[/tex]

The equation of new line perpendicular to given line will be:

[tex]y = m_1x+b[/tex]

Putting the value of m1

[tex]y = -x+b[/tex]

To find the value of b, the given point will be put into the equation

So,

[tex]-1 = -(4)+b\\-1 = -4+b\\-1+4 = b\\b = 3[/tex]

The final equation of line is: y = -x+3

Hence,

The equation in slope-intercept form through the point (4, -1) and is perpendicular to the line y = x + 2 is:

[tex]y = -x+3[/tex]

Answer:

y= 3/2x -14

Step-by-step explanation:

The formula to solve this problem is y- y1 = m(x-x1), so plug in the coordinates according to the formula: y-(-8)= m(x-4). Then, find the reciprocal of the slope, which is 3/2. Plug 3/2 to where the slope belongs: y+8=3/2(x-4). Calculate to solve the rest: y =3/2x -14

Answer:

100 because you cal look at the balz on that

Step-by-step explanation:

The measure of exterior angle ∠CAD of a triangle ABC is 100°.

From the given figure, ∠ACB=80° and ∠ABC=20°.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

From the given triangle,

m∠CAD=m∠ACB+m∠ABC

⇒ m∠CAD=80°+20°

⇒ m∠CAD=100°

Therefore, the measure of exterior angle ∠CAD of a triangle ABC is 100°.

Answer:

Pretty sure the Answer is:

=XOR(B4=12;C4<9) and =AND(B4=12;C>9) return TRUE, if the value in cell B4 is 12 and the value in C4 is 29.

Step-by-step explanation:

An =XOR function returns TRUE if any of the clauses in it are true, while an =AND function returns true only if both are true. Therefore, since in =XOR(B4=12;C4<9) B4 does equal 12, since this is an =XOR function. =AND(B4=12;C>9) is correct because B4 = 12 and C4 is greater than 9.

Hope this made some sense...
