The first one is number 2 the second one is 185.(could you also say what is in the drop down menu for the third one. The last one is Part A is 376 and part B is 1,3,4.Hoped it helped a bit :)

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.

PLEASE HELP I am confused on these equations

mamaluj [8]

Answer:

See below.

Step-by-step explanation:

I'll show you step by step how to do the synthetic division.

You are dividing polynomial -6x^4 + 22x^3 + 3x^2 + 15x + 20 by x - 4.

From the polynomial, you only need the coefficients in descending order of degree as they are written.

-6 22 3 15 20

In synthetic division, you divide by x - b. You are dividing by x - 4, so b = 4.

The 4 is written to the left of the coefficients of the polynomial.

___________________

4 | -6 22 3 15 20

___________________

This is what the setup looks like. You can see it in the problem you were given.

The first step is to just copy the leftmost coefficient straight down to below the line.

___________________

4 | -6 22 3 15 20

___________________

-6

Now multiply b, which is 4, by -6 and write it above and to the right.

___________________

4 | -6 22 3 15 20

-24

___________________

-6

Add 22 and -24 and write it next to -6.

-6 -2

Multiply 4 by -2 and write it above and to the right. Add vertically.

-24 -8

-6 -2 -5

Multiply 4 by -5 and write it above and to the right. Add vertically.

The 4 numbers in the second line are the coefficients of the quotient.

The quotient is 1 degree less than the original polynomial.

The quotient is: -24x^3 - 8x^2 - 10x - 20

The last number on the third line is the remainder. Since here the reminder is zero, that means that this division has no remainder. The remainder is 0/(x - 4)

Fill in the boxes with:

-24, -8, -10, -20

-6, -2, -5, -5, 0

-24x^3 - 8x^2 - 10x - 20

Find the inequality represented by the graph?

vitfil [10]

Answer:

y > -2/3x + 3

Step-by-step explanation:

Well lets first start with the beginning and look at its features.

Features

- Dashed line

- Shaded up

- negative slope

- y intercept at 3

____________________________________________________________

So if the line is dashed with the shade going up that means the inequality starts like this,

y >

We can tell that the y intercept is at 3 because that the point the line touches the y axis.

So we got y > 3,

To find slope we use the following formula,

$\frac{y^2-y^1}{x^2-x^1}$ ,

So we can use points (0,3) and (3,1).

1 is y2 and 3 is y1 so 1 - 3 = -2

3 - 0 = 3

Slope: -2/3x

Thus,

the inequality is y > -2/3x + 3.

Hope this helps :)

Which equation represents a circle that contains the point (-5, 3) and has a center at (-2, 1)? Distance formula: vaa -02 (x - 1

natali 33 [55]

Given:

The center of the circle = (-2,1).

Circle passes through the point (-5,3).

To find:

The equation of the circle.

Solution:

Radius is the distance between the center of the circle and any point on the circle. So, radius of the circle is the distance between the points (-2,1) and (-5,3).

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
