\bf (x-4)+(3x)+100=180\implies x-4+3x+100=180 \\\\\\ 4x+96=180\implies 4x=84\implies x=\cfrac{84}{4}\implies x=21

Which statement is true about figures ABCD and A'B'C'D?
Anika [276]

Answer:

Step-by-step explanation:

To understand the transformation better we will take a point B first.

Coordinates of B → (3, 0)

When we rotate this point by 180° counterclockwise about the origin, rule to be followed,

(x, y) → (-x, -y)

By this rule, coordinates of B'' will be,

B(3, 0) → B''(-3, 0)

Now we translate the point B by 2 units right.

Rule for the translation is,

(x, y) → [(x + 2), 0]

Following this rule,

B''(-3, 0) → B'[(-3+2), 0]

             → B'(-1, 0)

We can conclude with the statement, "Figure ABCD was rotated by 180° about the origin followed by the translation of 2 units to the right" to get the new figure A'B'C'D' similar to pre-image ABCD.

100 x 300 - 5+10-11-13
statuscvo [17]

The answer is 29, 981

Step-by-step explanation:

<em>First</em>) Since there are no parenthesis, you'd do 100 times 300 which equals 30,000

<em>Second</em>) Now youd go down the line since in PEMDAS, adding and subtracting are equal. 30,000-5 = 29,995

<em>Third</em>) 29,995+10= 30,005

<em>Fourth</em>) 30,005-11= 29,994

<em>Lastly</em>) 29,994-13= 29,981.

The distance between point (-4,6) and (3,-7)
inna [77]
Disatnce bewteen (x1,y1) and (x2,y2) is
D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}


so disatnce between (-4,6) and (3,-7) is
D=\sqrt{(-4-3)^2+(6-(-7))^2}
D=\sqrt{(-7)^2+(6+7)^2}
D=\sqrt{49+(13)^2}
D=\sqrt{49+169}
D=\sqrt{218}

the disatnce is √218 units or aprox 14.7648 units
