we can describe 3x-2 as an expression.
how can we describe the parts of the expression the arrows point to

Answers

Answer:

we can describe the parts of the expression that the arrows

point to 3x-2 such as:  

                                                  ↑(x variable)

                                                 [tex]3x-2[/tex] ← (2 constant)

                                                 ↓

                                                  (3 coefficient)

Step-by-step explanation:

Given the expression

[tex]3x-2[/tex]

As we have to  describe the parts of the expression the arrows

point to [tex]3x-2[/tex].

we can describe the parts of the expression that the arrows

point to 3x-2 such as:  

                                                  ↑(x variable)

                                                 [tex]3x-2[/tex] ← (2 constant)

                                                 ↓

                                                  (3 coefficient)

Therefore, it is clear that:

The upper arrow '↑' points to the variable part 'x' of expression which is 'x'.The lower arrow '↓' points to the coefficient part of the expression which is '3'.The arrow '←' points to the constant part of the expression which is '2'.

If you are considering speed regardless of direction, the average speed is:

(24 + 16) / 2 = 40 / 2 = 20mph

Although if direction matters, then one number has to be negative since the directions are opposite:

(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)

Using the triangle below, set up and solve an equation in order to find the value of x.

The midpoint of AB is M ( 1 , − 3 ). If the coordinates of A A are ( − 6 , − 7 ),what are the coordinates of B?

Answers

Answer:

a= -4

b=1

Step-by-step explanation:

Midpoint=(1,-3)=(x,y)

A=(-6,-7)=(x1,y1)

Let ,the coordinates of B be 'a and b' .

So,

B=(a,b)=(x2,y2)

Using ,midpoint formula,

(x,y)=(x1+x2\2 , y1+y2 \2)

or, (1,-3)=(-6+a\2 , -7+b \2)

Now,

Taking the corresponding sides,

or, 1 =-6+a/2

or, 1*2=6+a

or, 2=6+a

or, 2-6=a

a=-4

Then,

-3= -7+b/2

or, -3*2= -7+b

or, -6 =-7+b

or, -6+7=b

b=1

Given △ACP ≅ △LNX, find each missing measure.

Answers

9514 1404 393

Answer:

  XL = 13 cm, m∠L = 29°

  AC = 21 cm, m∠C = 29°

  PC = 13 cm, m∠Y = ??  (there is no angle Y in the figure)

Step-by-step explanation:

The figure on the right shows the triangles are isosceles, with XL = XN. That means also PA = PC. Those side lengths are all the same: 13 cm.

  PA = PC = XL = XN = 13 cm

In the same fashion, ...

  LN = AC = 21 cm

__

Of course, the angles have a similar relationship:

  ∠A = ∠C = ∠L = ∠N = 29°

The two base angles in the triangle add to 58°, so the third angle is ...

  180° -58° = 122°

  ∠P =∠X = 122°

_____

Additional comment

As is often the case in over-specified problems, the numbers shown are not consistent The attached figures show the length LN is actually incorrect for the angle and side specified for triangle ACP, or the angles are incorrect for the side lengths specified. What this means is that the answers you get will depend on how you work the problem. Above, we have taken the given numbers and relationships at face value, even though we know they are incorrect.

Are the lines y = –x – 4 and 5x -5y = 20 perpendicular? Explain.

Answers

Answer:

yes

Step-by-step explanation:

If 2 lines are perpendicular then the product of their slopes = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x - 4 ← is in slope- intercept form

with slope m = - 1

5x - 5y = 20 ( subtract 5x from both sides )

- 5y = - 5x + 20 ( divide all terms by - 5 )

y = x - 4 ← in slope- intercept form

with slope m = 1

Thus product of their slopes is - 1 × 1 = - 1

Therefore the lines are perpendicular

You are shopping for school supplies and want to decide where you should buy pencils from. SupplyCo sells a 10 pack of pencils for $0.95. SchoolShop sells a 10 pack of pencils for $1.45 but you have a $3.00 coupon. How many packs of pencils would you have to buy for the prices to be the same at each store?

Answers

Answer:

120 (60 from each store)

Step-by-step explanation:

Given that:

Price for 10 pack of pencils at SupplyCo = $0.95

Price for 10 pack of pencils at SchoolShop = $1.45

Discount coupon at SchoolShop = $3.00

Let the number of packs of pencils bought = [tex]2x[/tex] (in pack of 10)

Then [tex]x[/tex] will be the number of packs of 10 bought at each store.

Therefore, price at SupplyCo for [tex]x[/tex] packs (in pack of 10) = [tex]0.95x[/tex]

And price at SchoolShop for [tex]x[/tex] packs (in pack of 10) = [tex]1.45x-3.00[/tex] (because there is a coupon of $3.00)

As per question statement, price at both the stores is same:

[tex]0.95x=1.44x-3\\\Rightarrow 0.5x=3\\\Rightarrow x=6[/tex]

Therefore, number of packs bought = [tex]2x\times 10 = 2\times 6\times 10 =\bold{120}[/tex] (60 from each store)

Which statement is true about vertical angles. 1 point Vertical angles are congruent if two lines are parallel. If vertical angles are congruent, then two lines are parallel. Vertical angles are always congruent. Vertical angles are supplementary if two lines are parallel.

Answers

Answer:

Vertical angles are always congruent.

Step-by-step explanation:

Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.

Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:

<a and <b,

<c and <d.

Thus, <a is congruent to <b, and <c is congruent to <d.

Therefore, the standby that is true about vertical angles is that:

Vertical angles are always congruent.

Reflect over the line y = x

Answers

Answer:

After the reflection over the line y=x, the image points are:

A'(-1, -2)  B'(3, -1)  C'(2, -3)

Step-by-step explanation:

We know that when a point is reflected cross the line y = x, the x-coordinate, and y-coordinate change places.

i.e.

The reflection of the point (x,y) across  the line y = x is the point (y, x).

Given

A(-2, -1)B(-1, 3)C(-3, 2)

so after the points reflected cross the line y = x

P(x, y)                 →          P'(y, x)

A(-2, -1)               →          A'(-1, -2)    

B(-1, 3)                →          B'(3, -1)  

C(-3, 2)               →          C'(2, -3)

Therefore, after the reflection over the line y=x, the image points are:

A'(-1, -2)  B'(3, -1)  C'(2, -3)
