Pleaseee help!

Marie was trying to show her friend why -3 × -8 equals a positive product. This is what she wrote:

-3 × 0 = 0
-3 × (?) = 0
-3(8) + -3(-8) = 0


-24 + 24 = 0

What should Marie write in place of the question mark?
A. 8 + 8
B. -8 + (-8)
C. 8 + (-8)
D. -8 + 0

Step-by-step explanation:

So this is a rhyme that helps me remember how to add and subtract positive and negative numbers...

(To the tune of Row Row Row Your Boat)

Same sign add and keep

Different sign subtract

Keep the sign of the bigger number

Then you'll be exact

I know it sounds silly but it helped me :)

Answer:

-19

Step-by-step explanation:

Answer: k=22

Step-by-step explanation:

12+k/22=13

-12 -12

k/22=1

k=1*22

k=22

Answer:

19.1, rounded= 19

Step-by-step explanation:

115 divided by 6 = 19.1

Answer:

20 tanks

Step-by-step explanation:

Number of tanks = Total fish ÷ Number of fish that a tank can hold

                            = 115 ÷ 6

                             = 19 [tex]\frac{1}{6}[/tex]

                              = 20 tanks

Answer:

Step-by-step explanation:

You need $2500 plus the amount to print the tickets. So 2500+155= $2655.

$155 will break even and then the $2500 will be the profit.

Answer:

what are the statements

Step-by-step explanation:

Answer:

The slope-intercept form of the equation of this line is:

[tex]y=-x[/tex]

Hence, option 'c' is true.

Step-by-step explanation:

From the line equation, let us take two points

Finding the slope between two points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-1,\:1\right)[/tex]

[tex]m=\frac{1-\left(-1\right)}{-1-1}[/tex]

[tex]m=-1[/tex]

From the line graph, we can determine the y-intercept by setting x=0 and checking the y-value at x=0

at x=0, y=0

Thus, (0, 0) is the y-intercept

We know that the slope-intercept form of the line equation is

y=mx+b

where

As we have already determined m=-1 and y-intercept=b=0

so substituting m=-1, b=0 in the slope-intercept form of the line equation

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

[tex]y=(-1)x+0[/tex]

[tex]y=-x[/tex]

Thus, the slope-intercept form of the equation of this line is:

[tex]y=-x[/tex]

Hence, option 'c' is true.

Man, I have to be honest with you, I have no clue. But here is something else though. I had to take Geometry last year, and you are right. It does suck. But, you will get through it! There is a light at the end of the tunnel and you will get it! Keep up the good work!

Answer:

m<1 = 87

Step-by-step explanation:

Bro I got you! You ain't gotta hate school no more!

Right the equation like this

m<1 + m<2 = <TSV (plug in)

m<1 + 65 = 152 (subtract 65 from 152 to get m<1)

m<1 = 87

There you go!

Hope this helps ya!

Answer:

B is the correct chose

Step-by-step explanation:

Answer:

The sum of the triangle gives us the Fibonacci sequence. The sequence starts with 0 and 1, then adds along the road, such as 3+5=8, and 5+8=13.

It's a pattern going along while adding sequences together.

i hope this helps, it's not the best, but it works! :)

Answer:

10 1/4

Step-by-step explanation:

okay so the equation 4 3/8-(-5 7/8) needs to be simplified to a answerable equation by changing -(-5 7/8) to + 5 7/8

the reason for this is because when two subtraction signs are like this -(- it turns the number into a positive and we add instead of subtract.

4 3/8 + 5 7/8 = 9 10/8 = 10 2/8 = 10 1/4

I hope this helps you

Answer:

f(2)= -1

Step-by-step explanation:

f(2)=-3(2)+5= -6+5= -1

Answer:

Step-by-step explanation:

f(x)=-3x+5

f(2)= -3(2)+5

=-6+5 = -1

Answer:

The addition expression that represents the situation is;

175 + 100 + 100 - 55 -55

Step-by-step explanation:

Here, we want to write an addition expression to represent the situation

While the deposits are considered positive, the withdrawals are considered negative

So the addition expression will be;

175 + 100 + 100 - 55 - 55

Answer:

Nope

Step-by-step explanation:

It doesnt. Functions look like that

Answer: The point (5,7) is on the line 5x+6y = 67

=====================================================

Explanation:

(5,7) means x = 5 and y = 7 pair up

Plug in those values to get...

5x + 6y = 67

5*5 + 6*7 = 67

25 + 42 = 67

67 = 67

We get the same number on both sides after fully simplifying. This means the equation is true. A true equation in the last step means the first equation is true when (x,y) = (5,7).

Therefore, the point (5,7) is a solution and it is on the line 5x+6y = 67.

Answer:

The slope of line is (3,-2)

Answer:

(0,1)

Step-by-step explanation:

The zero of a function is where the answer is zero, so x=0 there. There's one point on this graph that has a point where x=0, and that is at y=1. Hope this helped :)

Answer:

3) the vertex is moved to the left 7 units

Step-by-step explanation:

When a number is inside the () and is being added or subtracted it goes to the opposite of the sign if it is + it goes left if it is - it goes right however with linear functions it is + right - left
