Answer:29.4

Step-by-step explanation:

alright so basically if he bought 3 plants for 17.94, then you just have to divide by three, like so. 17.94/3. you can do this with any calculator. now you have the original price of each plant, which is $5.98. now, multiply by two. $11.96. now add 17.94. $29.4.  that is the final answer

The cost of buying two more plants is $11.98

Cost is a value of money that a company had to spend to produce its goods or services.

Given that, Simon bought three plants at a nursery for $17.94

Cost of 3 plants = $17.94

Cost of 1 plant = $17.94/3

Cost of 1 plant = $5.98

Cost of 2 plant = $5.98*2 = $11.96

Hence, The cost of buying two more plants is $11.98

Answer:

- 10 < x < 7

Step-by-step explanation:

Inequalities of the type | x | < a

Always have solutions of the form

- a < x < a

Given

| 2x + 3 | - 5 < 12 ( add 5 to both sides )

| 2x + 3 | < 17 , then

- 17 < 2x + 3 < 17 ( subtract 3 from all 3 intervals )

- 20 < 2x < 14 ( divide the 3 intervals by 2 )

- 10 < x < 7

Step-by-step explanation:

Answer:

y= -2x-2

Step-by-step explanation:

All parallel lines have the same slope. So, the line we create must have a slope of -2. If we multiply the x value by -2, we can find b through an equation.

-4 would be x in this case because it's a point we pass.

So, our equation would be

y= -2(-4)+b

y=8+b

Now, we know that y is 8+b. We can find b by plugging in y=6, because those are the coordinates of P.

6=8+b

b=-2

Now we know that b is -2. We put this into the equation for the parallel line and get:

y=-2x-2

Answer: 1) D    2) B, A     3) A

Step-by-step explanation:

Domain is the x-values

Range is the y-values

Graph is a function if no x-values are duplicated

1) option D

  (3, 7), (1, 0), (8, 1), (-4, -3), (2, 7)

   ↓       ↓       ↓        ↓          ↓

Domain: x = {1, 1, 8, -4, 2}   → No duplicates so it is a function.

  (3, 7), (1, 0), (8, 1), (-4, -3), (2, 7)

       ↓       ↓       ↓          ↓        ↓

Range: y = {7, 0, 1, -3}    7 is a duplicate so only needs to be listed once

2) Domain = option B, Range = option A

x-values are between -5 (included = bracket) and +5 (not included = parentheses)

y-values are between -5 (included = bracket) and +5 (included = bracket)

3) option A

Domain: x = {1, 4, 5, 7, 9}   → 4 matches to both 5 and 7 so is NOT a function

Range: y = {3, 5, 7, 8}

Answer:

x=4

Step-by-step explanation:

Add six to both sides

x/4=1

Multiply by 4 on both sides

x=4

Regroup.

x/4 - 6 = -5

Add 6 to both sides

x/4 = -5 + 6

Simplify

x/4 = 1

Solve for x

x = 1×4

x = 4

Answer:

[tex]T = \frac{I}{PR}[/tex]

Step-by-step explanation:

Given

[tex]I = PRT[/tex]

What the question implies is that, we make T the subject of formula.

In other words, solve for T

We have that:

[tex]I = PRT[/tex]

Divide both sides by PR

[tex]\frac{I}{PR} = \frac{PRT}{PR}[/tex]

[tex]\frac{I}{PR} = T[/tex]

Reorder

[tex]T = \frac{I}{PR}[/tex]

Answer:

15 unites

Step-by-step explanation:

Given:

perimeter = 30 units

scale factor = 0.5

30 units * 0.50 = 15 units

The perimeter of the resulting triangle is 15 units.

The perimeter of the dilated triangle will be, 15 units.

Dilation means changing the size of an object without changing its shape.

Given that, The perimeter of a triangle is 30 units. If it is dilated with respect to origin by a scale factor of 0.5, we need to find the perimeter of the resulting triangle,

Since, the triangle is with respect to origin by a scale factor of 0.5,

Therefore, the perimeter of the original triangle will be reduced by 0.5 units,

The perimeter of dilated triangle = 30 x 0.5 = 15

Hence, the perimeter of the dilated triangle will be, 15 units.

Answer:

y=150x+200

Step-by-step explanation:

Given that:

Week : ____ 0___ 1 ___ 2 ____3 _____4

Balance : __200_350 _ 500 _ 650 ___800

Amount had in savings account = $200 before starting the job

x = number of weeks spent working

y = account balance

Slope intercept formula :

y = mx + c

C = intercept ; value of y when x = 0 = 200

m = slope or gradient = change in salary per month (350 - 200 = 500 - 350 = 650 - 500 = 800 - 650 = 150

Hence,

y = 150x + 200
