Answer: (-4,-3)

Step-by-step explanation:

(4,3) quadrant 1

(-4,3)quadrant 2 wasn't used in this

(4,-3) quadrant 3

(-4,-3)Quadrant 4

just trust me and I don't know how this is

10. Marcelle uses a total of 6 plates to add 110

madam [21]

Answer:

Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.

Step-by-step explanation:

There are 6 plates which consist of 25 lb plates and 5 lb plates.

We need to figure out how many of each one compose 110 lb.

Thus, 25 x 4 = 100... 4 plates of 25 pounds.

5 x 2 = 10 ... 2 plates of 5 lbs.

100+10= 110, which is our goal! And a total of 6 plates were used!

All things put into great consideration, Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.

I hope this helped!

What is the slope of the line passing through the points (−1, 3) and (4, −7) ? −4/3 2 3/4 −2

victus00 [196]

YOU FIND THE SLOPE BY PUTING THE NUMBER IN FOR THIS FORMULA Y2 - Y1/ X2 - X1 THIS WOULD BE -7 -3/ 4 +1 THIS WILL GIVE YOU -10/5 WHICH WHEN YOU SIMPLIFY WILL GIVE YOU THE ANSWER OF -2

PLEASE HELP. WILL GIVE BRAINIEST AND 60 POINTS if you show work so I can understand these.

vitfil [10]

1) use change in y/change in x to find the slope from two points:

change in y: 5-2=3

change in x: 0-(-1)=1

3/1=3 is your slope

2) if it is a direct variation, you know as x increases, y increases, both at constant rates

since y is 10 more than x in the example, it will always be 10 more than x

y=x+10 is your equation.

when x=9, y=19

now they could not be reffering to their difference in addition, but their difference in multiplication. In that case, y is 3 times x in the example, so it will always be 3 times x

y=3x is your equation

when x=9, y=27

3) the slope of this line is determined by change in y over change in x:

change in y: 4-4=0

you don't need to calculate the change in x because 0 divided by anything is 0, so that is your slope.

y=0x+b

4=0(1)+b

4=0+b

4=b

y=4 is your equation because 0 times x is zero. this means that it is a horizontal line with a constant y value of 4

y - value of y in a point =slope (x - value of x in a point)

y-(-1)=2/3 * (x-(-3))

y+1=2/3x+2/3(3)

y+1= 2/3x+2

y=2/3x+1

from solving point slope form, you can get to slope intercept form

5) not sure what this question is asking for

- a line?

- an expression equivalent to -1 and 2/3?

both of those aren't possible with the information given

6) parallel means same slope different y intercept

y=5x+b

-1=5(2)+b

-1=10+b

-11=b

y=5x-11

What is the value of x x-2/5 =7 what is the value of x

ahrayia [7]

Consider the puzzle:

"I have In mind a (secret) number. When I subtract 2/5 from this number I get 7. What is the number?"

To solve such puzzles we go backwards. We got 7 after we subtracted 2/5, so if we add 2/5 to 7, we get the secret number back.

Solving an equation is solving a puzzle about a secret number, which we call "x" instead of saying "something", all the time.

going backwards, means adding, if we subtracted, or dividing, if we multiplied.

So, to solve $x- \frac{2}{5}=7$ , we just need to add 2/5 back to x:

$x- \frac{2}{5}=7$

$x- \frac{2}{5}+\frac{2}{5}=7+\frac{2}{5}$

$x=7+\frac{2}{5}$

to add 7 and 2/5, multiply 7 by 5/5

7+2/5=7.(5/5)+2/5=35/5+2/5=37/5

Thus x= 37/5
