Either graph the points, or you can divide x by y for each set of points and if your answers are the same, then it is linear. 

Hope it helps!

2.c)in the diagram below, 4 m and ORIST at R. 5 $ 0 If m_1 = 63, find m_2.
pickupchik [31]

Data:

l and m are parallel lines

QR and ST are perpendicular in R

Angle 1 is 63°

The angle formed by perpendicular lines is a right angle (90°)

Angles 1 and 3 are alternate angles: angles that occur on opposite sides of a transversal line that is crossing two parallel.

Alternate angles are congruent, have the same measure.

\begin{gathered} m\angle1=m\angle3 \\  \\ m\angle3=63 \end{gathered}

The sum of the interior angles of a triangle is always 180°. In triangle QRT:

\begin{gathered} m\angle2+m\angle3+90=180 \\  \\ m\angle2+63+90=180 \\  \\ m\angle2+153=180 \end{gathered}

Use the equation above to find the measure of angle 2:

\begin{gathered} \text{Subtract 153 in both sides of the equation:} \\ m\angle2+153-153=180-153 \\  \\ m\angle2=27 \end{gathered}Then, the measure of angle 2 is 27°

How long will it take for the money to triple? Compounded continuously.
Artemon [7]

The formula for compounded continuously is :

A=Pe^{rt}

Here the Amount triples , so let us say the new amount A=3P

3P=Pe^{rt}

Cancelling P from both sides we get,

3=e^{rt}

Now here we are given rate is 2.75% or 0.0275,

3=e^{0.0275t}

solving for t we get

t=39.95 years

Please help ! Algebra
Simora [160]

Answer:

C

Step-by-step explanation:

y = (2x - 2) / 4 Interchange x and y

x = (2y - 2) / 4  Multiply both sides by 4

4x = 2y - 2       Add 2 to both sides.

4x + 2 = 2y       Divide both sides by 2

4x/2 + 2/2 = 2y / 2

2x + 1 = y

Now put 3 in wherever you see an x

2*3 + 1 = y

6 + 1 = y

7 = y

Anna is paid $15.00 per hour. She works a long 12 hour shift, the last 4 hours being paid a double time pay rate.
balu736 [363]

Answer: \Large\boxed{Wage=\$240}

Step-by-step explanation:

<u>Given information</u>

Paid = $15.00 / hour

Paid (Last 4 hours) = Doubled the usual pay rate

Total hour = 12 hours

<u>Given expression</u>

Wage = Pay rate × hours except for the last 4 hours + Double Pay rate × 4 hours

<u>Substitute values into the expression</u>

Wage = (15) × (12 - 4) + (15 × 2) × (4)

<u />

<u>Simplify values in the parenthesis</u>

Wage = 15 × 8 + 30 × 4

<u>Simplify by multiplication</u>

Wage = 120 + 120

<u>Simplify by addition</u>

\Large\boxed{Wage=\$240}

Hope this helps!! :)
