First attachment:
Indication words: each, gives, left.
> Each indicates multiplication
> left and gives indicate subtraction.

''5 packs obtains 4 cards each. 3 cards are given away,'' translates to 5 * 4 - 3

Therefore B = 5 * 4 - 3

Second attachment: 
Indication words: more, gives.
> More signifies addition 
> Gives signifies subtraction.

 The equation would be 229 + 35 - 149 = ?

Use PEMDAS. Note that you do addition first since it's before subtraction when we read this equation question left to right. 
229 + 35 - 149 = ? ⇒(229 + 35) - 149 = ? ⇒ 264 - 149 = 115; ? is 115

Answer: 115

Third attachment: 
I cannot answer; I don't know the choices in the choose boxes. 

Fourth attachment: 
You are incorrect for Part A. Raising 9 dollars EACH (*) day for a week (7 days) translates to, in mathematical terms, 9 * 7. 9 multiplied by 7 equals 63. 
The goal was to get to 439 dollars. If they have 63, how much MORE (+) do they need? To solve this, we do inverse operations of addition which is subtraction. Take 439 and subtract it by 63. 439 - 63 = 376. Check our work: 376 + 63 = 439? Yes. 

In conclusion the answer for Part A is A; $376.  

Part B - 
Answer 1: 9 book covers (9 * 8 = 72 ) + 1 calculator (1 * 9 = 9) = 81. Do not check this off because the result is not exactly 80.
Answer 2: 1 binder (1 * 4=4) + 8 calculators (8 * 9= 72) = 76. Do not check this off because the result is not exactly 80.
Answer 3: 1 book cover (1 * 8 = 8) + 8 calculators (8 * 9 = 72) = 80. Check this because the result is exactly 80.
Answer 4: 7 calculators (7 * 9 = 63) + 1 stapler (1 * 17) = 80. Check this because the result is exactly 80.

Answer 3 and 4 are correct in summary.

The given triangle is a right triangle

<h3>The length and slope</h3>

The coordinates are given as:

D (0,n), E(m,n), F(m,0)

The length is calculated using:

l=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2

So, we have:

DE=\sqrt{(0-m)^2 + (n-n)^2} = m

DF=\sqrt{(0-m)^2 + (n-0)^2} = \sqrt{m^2 + n^2

EF=\sqrt{(m-m)^2 + (n-0)^2} = n

The slope is calculated using:

m = \frac{y_2 -y_1}{x_2 - x_1}

So, we have:

DE = \frac{n -n}{0- m} = 0

DF = \frac{n -0}{0- m} = -\frac nm

EF = \frac{n -0}{m- m} = \mathbf{unde fined}

<h3>The coordinates of the midpoints</h3>

This is calculated using

m = 0.5 * (x_1 + x_2, y_1 + y_2)

So, we have:

DE = 0.5 * (0 + m, n+ n)=(0.5m, n)

DF = 0.5 * (0 + m, n+ 0)=(0.5m, 0.5n)

EF = 0.5 * (m + m, n+ 0)=(m, 0.5n)

<h3>The type of triangle</h3>

In (a), we have:

<u>Lengths</u>

DE= m

DF = \sqrt{m^2 + n^2

EF= n

<u>Slope</u>

DE  = 0

DF =  -\frac nm

EF  = \mathbf{unde fined}

The sides are not equal.

However, the 0 and the undefined slope implies that the triangle is a right triangle because the sides are perpendicular

It should be noted that the triangle cannot be graphed because the coordinates are not numeric

Which equation describes the line graphed above? A. -4x-5 B. -1/5x-4 C. -5x-4 C. -4x-1/5
SashulF [63]
Answer: B

Explanation:

The line go down one and turn right 5

So slope = -1/5x

And the y intercept is at -4

So B is the correct answer

Instructions: Find the equation of the line through point (−4,1) and parallel to y=−12x−2. Use a forward slash (i.e. "/") for fr
USPshnik [31]

Answer:

y = - 12x - 47

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

y = - 12x - 2 ← is in slope- intercept form

with slope m = - 12

Parallel lines have equal slopes, thus

y = - 12x + c ← is the partial equation

To find c substitute (- 4, 1 ) into the partial equation

1 = 48 + c ⇒ c = 1 - 48 = - 47

y = - 12x - 47 ← equation of parallel line
