The plus sign means that we have to sum all the terms inside of the second parenthesis, while the minus sign means that we have to change all the signs inside the last parenthesis:

$(3x+5)+(2x-9)-(4x+3)=3x+5+2x-9-4x-3$

Now we only have to gather all like terms:

$3x+2x-4x+5-9-3 = (3+2-4)x+(5-9-3)=x-7$

An object weighs 55.54 newtons. What is its mass if a gravitometer indicates that g = 9.83 m/s2?

Ksivusya [100]

Force = mass * acceleration
Mass = force / acceleration
Mass = 55.54 / 9.83
Mass = 5.6500508647 kilograms
Mass = 5.65 kilograms

(answer)increases, 22

(explanation)the numbers show that they increase going from 22 to 44 to 66. subtract 22 from either number (44 or 66) and youll get 22. add 22 to each number (44 and 66) and youll get the numbers 44 and 66, meaning the mouses travel increases by 22 feet.

Which value of x will make the triangles similar by the SSS similarity theorem

masha68 [24]

Answer:

x = 30.

Step-by-step explanation:

For the triangles to be similar corresponding sides must be in the same ratio.

So 50/ 75 = x / 45

75x = 50*45

x = 50* 45/75

= 2 * 45 / 3

= 30. (answer).

Write the equation of the line that is the perpendicular bisector of the segment with endpoints (4, 1) and (2, -5)

Sedbober [7]

Answer: $\bold{y=-\dfrac{1}{3}x-1}$

Step-by-step explanation:

(4, 1) & (2, -5)

First, find the slope (m) and then the perpendicular (opposite reciprocal) slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\\m=\dfrac{-5-1}{2-4} = \dfrac{-6}{-2}=3\quad \rightarrow \quad m_{\perp}=-\dfrac{1}{3}\\$

Next, find the midpoint of (4, 1) and (2, -5):

$Midpoint=\bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\\.\qquad \qquad=\bigg(\dfrac{4+2}{2},\dfrac{1-5}{2}\bigg)\\\\\\.\qquad \qquad=\bigg(\dfrac{6}{2},\dfrac{-4}{2}\bigg)\\\\\\.\qquad \qquad=(3, -2)$

Lastly, input the perpendicular slope and the midpoint into the Point-Slope formula to find the equation of the line:

$y - y_1 = m_{\perp}(x - x_1)\\\\y - (-2) = -\dfrac{1}{3}(x - 3)\\\\y + 2=-\dfrac{1}{3}x +1\\\\y =-\dfrac{1}{3}x - 1\\$
