Answer:

Hi there

Your answer is

( 3,8 )

Step-by-step explanation:

3 units right means to add 3

4 units up means to add 4

(0+3, 4+4)

Answer:

(3,-3)

Step-by-step explanation:

you first add 3 to zero as your are going right on the x scale. then you subtract 4 since you are going up on the y scale.

Answer:

-30x 6 = -9 -3x=

x = 3/13

Answer:

  -2 ≤ x < 12

Step-by-step explanation:

-15x +4 ≤ 34

Add 15x-34 to both sides

  -30 ≤ 15x

Divide by 15

  -2 ≤ x

__

-6x +70 > -2

Add 6x +2 to both sides

  72 > 6x

Divide by 6

  12 > x

__

The two solution spaces overlap. Since the AND of the two inequalities is involved, the solution of both is just that part of the number line where there is overlap.

The solution is ...

  -2 ≤ x < 12

Answer:

to solve, really, you just combine like terms and follow the formula

Step-by-step explanation:

for example:

y2-y1=m(x-x1)

y-3=4(x-5)

y-3=4x-20

y=4x-23

Answer:

2,3,-1

Step-by-step explanation:

Part (i)

Answer:  m/n

--------------------

Explanation:

You divide the total bill over the number of people at the dinner. This leads to the quotient and the amount each person pays (each person pays the same amount).

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

Part (ii)

Answer:  80 dollars

--------------------

Explanation:

Plug in m = 400 and n = 5 to get

m/n = 400/5 = 80

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

Part (iii)

Answer:  m = 7x

--------------------

Explanation:

x = m/n

x = m/7

7x = m ... multiply both sides by 7

m = 7x

The total bill is 7 times of what each person paid.

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

Part (iv)

Answer:  7 people

--------------------

Explanation:

x = 20 is the amount each person paid

m = 140 is the total bill

n = number of people who went to dinner

x = m/n

20 = 140/n

20n = 140 ..... multiply both sides by n

n = 140/20 ..... divide both sides by 20

n = 7

Seven friends went to do dinner, splitting a $140 bill, paying $20 each

Answer:

m/n; $80; 7*x; 7 friends

Step-by-step explanation:

(I) $x=$m/n

(II) $x=400/5=$80

(III) $m=7*x

(IV) n=140/20=7

Given:-

Step-by-step explanation:

4z+7= 31

4z= 31-7

4Z= 24

Z= 24/4( dividing by 2)

z = 6/1

An inequality to represent the number of bags of popcorn sold, p, and the number of cups of lemonade sold, c, in order to make a profit is [tex]3p + 2c > 120[/tex].

Given the following data:

To write an inequality to represent the number of bags of popcorn sold, p, and the number of cups of lemonade sold, c, in order to make a profit:

In order for the soccer team to make profit, the sum of the total cost of goods sold must be greater than $120.

Therefore, the mathematical expression is represented as follows:

Answer: (-7 , 25)

Step-by-step explanation: I graphed and that’s the point I got.

Answer:

x = 3.75 or [tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

17 = -13 - 8x

add 13 to both sides

17 + 13 = -13 + 13 + 8x

30 = 8x

divide both sides by 8

30/8 = 8x /8

3.75 = x
