Answer:

Statement 1: Quadrilateral PQRT; line QSV; line PTV line QV bisects line RT, and line OR is parallel to line PV

Statement 3: angle QSR is congruent to angle VST

Statement 5: Triangle RSQ is congruent to angle TSV

Reason 1: Given

Reason 2: If a line bisects a segment, then it divides the segment into two congruent segments.

Reason 4: If two lines are parallel, then the alternate interior angles are congruent.

Step-by-step explanation:

The first statement will always be your given statements.

Write the equation that passes through the following points: (5,0) and (−10,−5)

Vikentia [17]

Answer:

The answer is:

$y = \frac{1}{3} x - \frac{5}{3}$

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

$y = mx + b$

❃Incase you also forgot, The is what the slope formula is ☟

$m = \frac{y_2 - y_1 }{x_2 - x_1}$

➊ First: We are going to be solving for the slope.

$m = \frac{ - 5 - 0}{ - 10 - 5} = \frac{ - 5}{ - 15} = \frac{1}{3}$

➋Second: We find the y-intercept.

$y = mx + b \\ 0 = \frac{1}{3} (5) + b \\ 0 = \frac{5}{3} + b \\ \frac{ - \frac{5}{3} = - \frac{5}{3 } \: \: \: \: \: \: \: \: \: \: \: \: }{ - \frac{5}{3} = b}$

➌Third: Plug in.

$y = \frac{1}{3} x - \frac{5}{3}$

Which of the following is the graph of y = cos(2x)?

irinina [24]

Answer:

Select the one which meets the following characteristics.

Step-by-step explanation:

y = cos(2x)

Characteristics:

Mean line at y = 0

Amplitude = 1

Period = 360/2 = 180° or pi radians

i.e one complete cos cycle is 0 to 180, next is 180 to 360 and so on

Range : from -1 to 1

A square is shown below. Which expression can be used to find the area, in square units, of the shaded triangle in the square?

ELEN [110]

Answer:

Area = $\frac{1}{2} (6)(6)$

Step-by-step explanation:

Area of Triangle = $\frac{1}{2} (Base)(Height)$

Where Base = 6 , Height = 6

Area = $\frac{1}{2} (6)(6)$

Area = 3 * 6

Area = 18 units^2
