Which of the following represents a dilation that is a reduction with a scale factor larger than 0.5?
A (x, y) → (0.3x , 0.3y)
B (x, y) → (0.8x , 0.8y)

Answer:

small = 1.25

medium = 2.10

large = 4.50

Step-by-step explanation:

your equations would be

4x+2y+8z=45.2

7x+2y+5z=35.45

2x+9y+16z=93.4

solve using gaussian elimination.

Answer:

you do not move forward or backward but instead, remain in the exact position

Step-by-step explanation:

** The numbers are repeated in this question 444 is actually 4 and 000 is actually 0 **

In these board games and in many other concepts zero (0) acts as a neutral value since it is neither a negative nor a positive. In this board game, drawing a card with a value of 0 means that you do not move forward or backward but instead remain in the exact position that you already are. Usually, this also means that your turn is skipped and there is no change in your board piece's/character's status or position in the game

Answer:

stay in the same spot because its 0

Answer:

the last one

Step-by-step explanation:

Answer:

12.5w = 419.38

and

15.5w = 419.38

Step-by-step explanation:

find the total cost of all the computer parts.

= 259.99 + 2* 39.95 + 79.49 = $419.38

Shana will save $12.50 per week and Marie will save $15.50

per week

therefore we can create two inequalities

12.50 * w = 419.38

12.5w = 419.38

w = 419.38/12.5

w = 33.5504

15.50*w = 419.38

15.5w = 419.38

w = 419.38/15.5

w =27.0568

Answer:

x=

Step-by-step explanation:

4+x-2=5x+2-2

2+x-x=5x-x

2=4x

2/4

Answer:

x = 45.5

Step-by-step explanation:

Move one side of the equation to the other side of the equal sign.

4 + x = 5x + 2

x = 5x - 2

=4x - 2

Then put the 180 on the empty side because the total is 180.

180 = 4x - 2

Then solve for x

182 = 4x

45.5 = x

Answer:

x = 6

Step-by-step explanation:

Since the sides are congruent (definition of isosceles triangle), the angles must also be congruent.

Step 1: Set up equation

4x + 20 = 8x - 4

Step 2: Solve for x

Answer:

x = 78

Step-by-step explanation:

Look at Triangle DBH. Two of its angles are known. Let y = <DHB

47 + 31 + y  = 180        All triangles have 180 degrees. Combine the left.

78 + y = 180                Subtract 78 from both sides.

78-78+y = 180-78        Combine

y = 102

Notice that y + x = 180   They form a straight line.

102 + x = 180                   Subtract 102 from both sides.

x = 78

You should notice that x is an exterior angle. (I didn't at first).

Exterior angles are the sum of the two remote interior angles which in this case, are 31 + 47 = 78

Much shorter and much easier.

Step-by-step explanation:

Answer:

when x = 24, y = 108

Step-by-step explanation:

The equation relating x and y is

y = kx ← k is the constant of proportion

To find k use the condition when x = 4 , y = 18, then

18 = 4k ( divide both sides by 4 )

4.5 = k

y = 4.5x ← equation of proportion

When x = 24, then

y = 4.5 × 24 = 108

Answer:

Raul needs sales of $924.

Step-by-step explanation:

It looks like Raul earns commission at 1/7 of his sales.  (40/280 = 1/7).

[tex]\frac{40}{280}=\frac{132}{x}\\ 40x = 280*132\\x=924[/tex]

Answer: D

Step-by-step explanation:

Answer:

there is no solution.

Step-by-step explanation:

1. it would have to be 8 to make the answer 16 because 2*8= 16 but 4*2=8 and the answers other than no solution are all 4 in positive and negative so i would say no solution.

Answer:

C

Step-by-step explanation:

Sum of angles in triangle is 180 degrees.

28°+58°+ x= 180 degrees

x=94 degrees

sum of angles on a straight line is 180 degrees

thus, 94 degrees + ? = 180 degrees

?= 86 degrees

angle TGF is 86 degrees

Answer:

5. x=0.6 or 3/5 (it's just the fraction and decimal form)

6. y=10

Step-by-step explanation:

5. We are given y=5 and x=-3, so whenever  and need to find x if y=-1

We need to find the "x" for the second proportion

Using this information we can create a ratio or proportion. To understand this better, (usingy=5 and x=-3) we can say that for every 5 of something (y) we have -3 of something (x). We can create a "key" using the proportionality:[tex]\frac{y}{x}[/tex]

here is our proportion [tex]\frac{5}{-3} *\frac{-1}{x}[/tex]

lets cross multiply first, 5x=-1(-3)  this simplifies to 5x=3, divide 5 from both sides, 5x/5=3/5  and you x=3/5, so this means that x is 3/5 or 0.6 as decimal

6. Lets set up our "key" again [tex]\frac{y}{x}[/tex],

our ratio is for every 25 something (y) we have 15 something(x) or 25/15 or 25:15

[tex]\frac{25}{15} *\frac{y}{6}[/tex]   this is our proportion, lets cross multiply to solve for "y"

25*6=15y this simplifies to 150=15y

lets divide both sides by 15, 150/15-15y/15  and we get our final answer

10=y so our why for this is 10

Answer:

6. [tex]\displaystyle 10 = y[/tex]

5. [tex]\displaystyle \frac{3}{5} = x[/tex]

Step-by-step explanation:

You are simply dealing with direct proportional relationships:

[tex]\displaystyle \frac{y}{6} = \frac{25}{15}; 10 = y[/tex]

These are considered equivalent improper fractions. When simplified, you get [tex]\displaystyle 1\frac{2}{3}.[/tex]

_______________________________________________

[tex]\displaystyle \frac{-1}{x} = \frac{5}{-3}; \frac{3}{5} = x[/tex]

If you look closely, you can tell that there is a 1 being used here, and that you need to divide it by the multiplicative inverse of [tex]\displaystyle \frac{5}{3},[/tex]which is [tex]\displaystyle \frac{3}{5},[/tex]and sinse both terms are negative integers, you leave the result as is.
