write an expression to represent the problem.

Answer:

Step-by-step explanation:

y ≤ 2x + 2  ⇒   2x → line increasing,  ≤ → solid line, y≤ → shade below line  

¹/₂x + y < 7

y < -¹/₂x + 7 ⇒  -¹/₂x → line decreasing,  < → dashed line, y< → shade below line  

y − 3 ≥ 0

y ≥ 3  ⇒  0x → line parallel to X-axis,  ≥ → solid line, y≥ → shade above line  

Answer:

(400-x) / 3

Step-by-step explanation:

Savannah had 400 chocolate chips. She saved x chips for a garnish, and mixed the rest of the chocolate chips evenly into 3 pans of brownies. Write your answer as an expression

Solution

Total chocolate chips Savannah has=400

Saved chips for garnish =x

Total chocolate chips remaining= 400 - x

We subtract the saved chocolate chips because when an item is saved, it will be deducted from the original Quantity

She mixed the rest of the chocolate chips evenly into 3 pans of brownies

That is,

Remaining chocolate chips (400 - x) is mixed evenly into 3 pans of brownies

(400 - x) / 3

Therefore, the answer is given by the expression:

(400-x) / 3

the answer is (-9,-7) it flips into the 3rd quadrant.

Answer:

x = 54/7 y= -4/7

Step-by-step explanation:

Answer:

x = 54/7 and y = -4/7

Step-by-step explanation:

x+3y=6

4x-2y=32

= 4 ( x+3y=6 )

= 4x +12y = 24 - 4x -2y = 32

=14y = -8

y = - 4/7

X + 3(-4/7) = 6

x+-12/7 = 6

x = 54/7

Answer:

A.

Step-by-step explanation:

This is a geometric sequence with common ratio -12/-3 = 4  ( -48/-12  = 4 and  -192 / -48 = 4).

nth term = a1 r^(n - 1) so the 8th term

= -3 * (4)^(8 - 1)

= -49,152.

The 8th term of the geometric sequence is -768

A sequence is an ordered list of numbers (or other elements like geometric objects), that often follow a specific pattern or function.

A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

Formula for the n th term of a geometric sequence in the form

aₙ=a₁ rⁿ

Given sequence is   -3, -12, -48, -192, . . .

It is a geometric sequence with the ratio between consecutive terms is 4

i.e. r = 4

a₁ = -3

a₈ = -3 ×4⁸

   =-768

Thus the 8th term of this sequence is -768

Answer:

a = 0

Step-by-step explanation:

a + 5 = -5a + 5      subtract 5 from both sides

a + 5 - 5 = -5a + 5 - 5

a = -5a                add 5a to both sides

a + 5a = -5a + 5a

6a = 0                 divide both sides by 6

6a / 6  =  0 / 6

therefore,

a = 0

Answer:

1 ft : 2.5 yd or 1 ft : 2 1/2 yd

Step-by-step explanation:

He wants a real dimension of 10 yards to be represented by a scale dimension of 4 ft.

4 ft : 10 yd

Divide both sides by 4.

1 ft : 2.5 yd or 1 ft : 2 1/2 yd

Answer:

A. Plane B because it was 9.33 miles away

B. 48 units

Step-by-step explanation:

A. Since the airplanes fly at an angle to the runway, their direction forms a triangle with the runway with their height above the ground as the opposite of the angle and their distance from the airport as the hypotenuse.

So for airplane A with 44° angle of departure,

sin44° = y/h where y = height above the ground and h = distance from airport

So h = y/sin44° = 6/sin44° = 8.64 miles

So for airplane B with 40° angle of departure,

sin40° = y/H where y = height above the ground and H = distance from airport

So H = y/sin40° = 6/sin40° = 9.33 miles

Since airplane B is at 9.33 miles away from the airport whereas airplane A is 8.64 miles from the airport, airplane B is farther away.

B. We know that scale factor = new size/original size

Our scale factor = 4 and original size = 12 units. So,

new size = scale factor original size = 4 × 12 = 48 units.

Answer:

$4.59

Step-by-step explanation:

At the sale price:

5 paints set cost Jasmine $16.45

Each paint set = Total cost of 5 paints set / 5

= $16.45 / 5

= $3.29

What was the price of 1 paint set before the sale?

Because the store reduces the price of each paint set by $1.30 before selling, we will add $1.30 to the price of each paint set during sales

Price of each paint set during sales = $3.29

price of 1 paint set before the sale = $3.29 + $1.30

= $4. 59

The cost of 1 paint set before the sale was $4.59

From the question, we are told that 5 paints set cost $16.45. From this, we can know the cost of 1 paint.

Cost of 1 paint set = cost of 5 paints set / 5

Cost of 1 paint set = $16.45 / 5

Cost of 1 paint set = $3.29

We are then asked the price of 1 paint set before the sale?

Since the store reduces the price of each paint set before selling it, this them means that we will add $1.30 to the price during the sales .

If the cost of 1 paint set during sales is $3.29, then

the cost of 1 paint set before the sale = $3.29 + $1.30

the cost of 1 paint set = $4. 59

Area of parallelogram= base * height

Answer:

A= L × W

or

A = S × S

Step-by-step explanation:

A parallelogram are shapes with 4 sides. To find its area, we must do the following formula.

(For rectangle, etc...)

Area = Length × Width

A represents Area

L represents Length

(For a square)

Area = Side × Side

A represents Area

S represents Side

Always remember that the answer of a question that is looking for the area of a 2D shape is always squared. (Let x represent the answer and cm as the example of unit of measurement: x cm²)

Answer:

The four true statements are:

1. If an angle is a right angle,  it measures 90°.

2. If an angle measures 90°, it is a right angle.

3. If an angle is not a right angle,  it does not measure measure 90°.

4. If an angle does not measure 90°, it is not a right angle.

Step-by-step explanation:

Given the biconditional statement:

An angle is a right angle if and only if it measures 90°.

To find:

Four true conditional statements.

Solution:

First of all, let us the learn the concept of four true conditional statements from a given biconditional statement.

Let the biconditional statement be "[tex]a[/tex] is true if and only if [tex]b[/tex] is true.

Then the four true statements can be written as:

1. If [tex]a[/tex] is true then [tex]b[/tex] is true.

2. If [tex]b[/tex] is true then [tex]a[/tex] is true.

3. If [tex]a[/tex] is false then [tex]b[/tex] is false.

4. If [tex]b[/tex] is false then [tex]a[/tex] is false.

Here [tex]a[/tex] is "an angle is a right angle"

[tex]b[/tex] is "it measures 90°" .

So, the four true statements are:

1. If an angle is a right angle,  it measures 90°.

2. If an angle measures 90°, it is a right angle.

3. If an angle is not a right angle,  it does not measure measure 90°.

4. If an angle does not measure 90°, it is not a right angle.

There are no triangles given, so I will explain what congruent triangles are.

Step-by-step explanation:

Two triangles are said to be congruent if the three sides and the three angles of both the angles are equal in any sense.

Consider the following conditions for two triangles:

- Two angles and corresponding side, of the two triangles are equal

- Two sides and angle between the two triangles are equal

- Hypotenuse and Leg of two right angled triangles are equal.

If all these conditions are met for any two triangles, they are said to be congruent.

Step-by-step explanation:

1. substitute- (x,y)=the original coordinates (9,9) right?

2. So no you want to do x, you have 9 and if you are moving right 5 units it'll be 9+5 because x is left to right on a graph.

9+5=14 therefore (14,y)

3. Now you do y, y is up and down. So you want to go down 4, you subtract 4 from 9 giving you five. Now you have (14,5)
