Eric's mother drives to work in 20 minutes when driving at her usual speed. When traffic is bad,she drives 10 miles per hour slower, and the trip takes 10 minutes longer. What is Eric's mother's usual speed

Answer:

m=1/2, b=1

Step-by-step explanation:

y=1/2x+1

y=mx+b

y is the y coordinate

m is the slope

x is the x coordinate

b is the y-intercept

You would identify that 1/2 is substituted into the equation as m aka the slope and 1 substituted for the b value aka y-intercept

Answer:

The correct answer is Option B: $39000

Step-by-step explanation:

Given that

Price of House = P = $650000

Rate of commission = r= 6%

In order to calculate the commission amount of Kathy, we only have to calculate 6% of $650000 or by simply multiplying the price by 0.06

So,

[tex]Commission = 6\%\ of\ 650000\\=0.06*650000\\=39000[/tex]

The commission is: $39000

Hence,

The correct answer is Option B: $39000

Answer:

900

Step-by-step explanation:

The equivalent degree measure of 5π ard is 900°.

We have I, II, III, IV quadrants.

In quadrant I the referece angle Ф is Ф.

In quadrant II the referece angle Ф is (π - Ф).

In quadrant III the referece angle Ф is (π + Ф).

In quadrant IV the referece angle Ф is (2π - Ф).

We know π is equal to 180°.

The conversion of radian to degrees is we multiply the radian value by 180°/π.

Given, The radian measure is 5π.

Therefore, the equivalent degree measure is,

= (5π)×(180/π).

= (5×180)°.

= 900°.

The equivalent conversion of radian to degrees.

Answer:

(a+2) (a-18)

Step-by-step explanation:

Factoring a2-16a-36

The first term is, a2 its coefficient is 1 .

The middle term is, -16a its coefficient is -16 .

The last term, "the constant", is -36

Step-1 : Multiply the coefficient of the first term by the constant 1 • -36 = -36

Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .

-36 + 1 = -35

-18 + 2 = -16 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2

a2 - 18a + 2a - 36

Step-4 : Add up the first 2 terms, pulling out like factors :

a • (a-18)

Add up the last 2 terms, pulling out common factors :

2 • (a-18)

Step-5 : Add up the four terms of step 4 :

(a+2) • (a-18)

Which is the desired factorization

Answer: Elena's running speed = 5 miles per hour.

Step-by-step explanation:

Length of track = [tex]\dfrac14 \text{ mile}[/tex]

Time taken to complete one lap = [tex]\dfrac{1}{20}[/tex] of an hour.

Elena's running speed = [tex]\dfrac{Distance}{Time}[/tex]

[tex]=\dfrac{\dfrac14}{\dfrac1{20}}\text{ miles per hour}\\\\=\dfrac{20}{4}\text{ miles per hour}\\\\=5\text{ miles per hour}[/tex]

Hence, Elena's running speed = 5 miles per hour.

Answer:

[tex]\frac{25}{10x-1}[/tex]

Step-by-step explanation:

The multiplicative inverse of "a" is " [tex]\frac{1}{a}[/tex] "

a × [tex]\frac{1}{a}[/tex] = 1

~~~~~~~~~~~

[tex]\frac{1}{5}[/tex] ( 2x - [tex]\frac{1}{5}[/tex] ) = [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex]

1 ÷ ( [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x}{25}[/tex] - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x - 1}{25}[/tex] ) = [tex]\frac{25}{10x-1}[/tex]

The multiplicative inverse of the product is  [tex]\frac{25}{10x-1}[/tex]
