Divide 97/120, then multiply it by 100. After that, you can subtract the answer by 100. The answer will be negative, so make it positive.

1.5( x + 4) -3 = 4.5 ( x - 2 )
Hitman42 [59]

Answer:

Step-by-step explanation:

1.5(x + 4) - 3 = 4.5(x - 2)

1.5x + 6 - 3 = 4.5x - 9

1.5x + 3 = 4.5x - 9

3 + 9 = 4.5x - 1.5x

12 = 3x

12/3 = x

Which figure is the image produced by applying the composition t 0,3 r 0,90 to figure R?
Maksim231197 [3]

Answer:

Option A is correct

The only figure after composition of t_{0 , 3} (r_{0,90^{\circ}}) to figure R is Figure H

Step-by-step explanation:

From the given figure in R;

The coordinates in Figure R ;

(1 , -1) , (2, -2) ,(4, -2) ( 0, -4)

Composite function defined as when one function is substituted into another function.

To Apply the composition t_{0 , 3} (r_{0,90^{\circ}}) to figure R;

First apply the Reflection r_{0, 90^{\circ}} in Figure R;

The rule of reflection is given by:

(x,y) \rightarrow (-y,x)

By applying the rule of reflection in Figure R ,

then, the coordinates becomes;

(1 , -1) \rightarrow (1, 1)

(2 , -2) \rightarrow (2, 2)

(4 , -2) \rightarrow (2, 4)

(0, -4) \rightarrow (4, 0)

Now, apply the translation t_{0,3}

Translation : It is a type of transformation that moves each point in a figure the same distance in the same direction.

then,

the rule of translation is:

(x,y) \rightarrow (x+0,y+3)

Apply the rule of translation on coordinates (1,1) , (2,2),  (2,4) and (4,0)

then

(1 , 1) \rightarrow (1+0 1+3) =(1,4)

(2, 2) \rightarrow (2+0 2+3) =(2, 5)

(2, 4) \rightarrow (2+0 4+3) =(2 ,7) and

(4, 0) \rightarrow (4+0 0+3) =(4 ,3)

Then, the only figure after composition of t_{0 , 3} (r_{0,90^{\circ}}) to figure R is Figure H

Pls help<br> (extra characters)
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

2) Let 't' be the temperature

t < 7

Height be 'h'

h >= 42

Cos be represented by 'c'

c >= 125

3) Distributive property: a*(b +c) =(a*b) + (b*c)

2(5a + 3b) + 5a  +2b = 2*5a + 2*3b + 5a + 2b

                                   = 10a + 6b + 5a + 2b

                                  = 10a + 5a + 6b + 2b   {Combine like terms}

                                  = 15a + 8b

6y + 2(3x + 5) + 2y + 3 = 6y + 2*3x + 2*5 + 2y + 3

                                     = 6y + 6x + 10 + 2y + 3

                                     = 6y  + 2y + 10 +3 + 6x

                                      = 8y + 13 + 6x
