The graph below shows data that was collected from a person's commute to work over the course of one month. The equation of the

trend line is y=-6/5x + 86
If the time of the commute is 45 minutes, what would you expect the speed of the commute to be?

In this figure, AB ||CD and m<1=135. What is m<7

telo118 [61]

Answer:

135

Step-by-step explanation:

Angles 1 and 3 are vertical angles, so they are congruent.

Since angle 1 measures 135 deg, angle 3 also measures 135 deg.

Angles 3 and 7 are corresponding angles of parallel lines cut by a transversal, so they are congruent.

Since angle 3 measures 135 deg, angle 7 also measures 135 deg.

Answer: m<7 = 135 deg

Help on 22 and 23 please

hram777 [196]

Answer:

22.

R= -8, 15

S= -5, 9

T= -8,9

23.

J = 4, 4

K = 4, 3

L = 1, 1

M = 1, 4

Step-by-step explanation:

rotation of -90= y, -x

so R (-7, -5) = -5,7

S (-1, -2) = -2, 1

T (-1, -5) = -5, 1

now we translate 3 left (x-3) and 8 up (y+8)

R (-5, 7) = -8, 15

S (-2, 1) = -5, 9

T (-5, 1) = -8, 9

reflection of x-axis= x, -y

J (-4, 4) = -4, -4

K (-3, 4) = -3, -4

L (-1, 1) = -1, -1

M (-4, 1) = -4, -1

Then a 180° rotation is (-y, -x)

J (-4, -4) = 4, 4

K (-3, -4) = 4, 3

L (-1, -1) = 1, 1

M (-4, -1) = 1, 4

The approximate number of bicycles in the United States in the year 2007 was 14,000,000. How can this number be expressed in sci

elena-s [515]

Answer:

$1.4*10^7$

Step-by-step explanation:

we have

$14,000,000$

Remember that

$14,000,000=1.4(10,000,000)$

and

$10,000,000=1*10^7=10^7$

substitute

$14,000,000=1.4*10^7$

9x/10y=7/w solve for w

egoroff_w [7]

Answer:

<h2> $w = \frac{70y}{9x}$ </h2>

Step-by-step explanation:

<h3> $\frac{9x}{10y} = \frac{7}{w}$ </h3>

First of all cross multiply

We have

<h3> $9xw = 70y$ </h3>

Next divide both sides by 9x to make sure that w stands alone

That's.

<h3> $\frac{9xw}{9x} = \frac{70y}{9x}$ </h3>

We have the final answer as

<h3> $w = \frac{70y}{9x}$ </h3>

Hope this helps you.
