Step-by-step explanation:

what ? you cannot do even simplest subtractions ?

what is it you don't understand here ?

how such a function works ?

you take every value for x (the input variable or argument), put it in place of the "x" (this is nothing else than a placeholder for the actual values) and then perform the mathematical operations. y is then the result of that.

x = 0

y = 0 - 7 = -7

the ordered pair of (x, y) is (0, -7)

x = 1

y = 1 - 7 = -6

(1, -6)

x = -3

y = -3 - 7 = -10

(-3, -10)

x = -5

y = -5 - 7 = -12

(-5, -12)

Answer:

a) Junnie walked farther than Maurice

b) Junnie walked .62 miles farther than Maurice

Step-by-step explanation: Because speed times time equals distance, to find how far each person traveled you multiply their speed and time.

Distance=speed×time

Junnie:

2.5hrs×3.2mph=8 miles

Maurice:

1.8hrs×4.1mph=7.38 miles

8-7.38=.62 (the difference between the two)

PLEASE HHELP!!! Bring the fraction:

Anna35 [415]

Answer:

$\frac{b}{7a^2c} = \frac{5abc^2}{35a^3c^3}$

$\frac{a}{a - 4} = \frac{-a^2 - 4a}{16 -a^2}$

Step-by-step explanation:

Given

$\frac{b}{7a^2c}$

Express the denominator as $35a^3c^3$

To do this, we divide $35a^3c^3$ by the denominator

$\frac{35a^3c^3}{7a^2c} = 5ac^2$

So, the required fraction is:

$\frac{b}{7a^2c} * \frac{5ac^2}{5ac^2}$

$\frac{5abc^2}{35a^3c^3}$

Hence:

$\frac{b}{7a^2c} = \frac{5abc^2}{35a^3c^3}$

Given

$\frac{a}{a - 4}$

Express the denominator as $16 - a^2$

Multiply the fraction a+4/a+4

So, we have:

$\frac{a}{a - 4} * \frac{(a + 4)}{(a + 4)}$

Apply difference of two squares to the denominator

$\frac{a^2 + 4a}{a^2 - 16}$

Take the additive inverse of the numerator and denominator

$\frac{-(a^2 + 4a)}{-(a^2 - 16)}$

$\frac{-a^2 - 4a}{16 -a^2}$

Hence:

$\frac{a}{a - 4} = \frac{-a^2 - 4a}{16 -a^2}$

Richard was earning $10/hr working for Diane’s landscaping company. Diane said that productivity was decreasing, so everyone had

pentagon [3]

Answer:

Richard is making $9.6 per hour now

Step-by-step explanation:

Given:

Initial amount Richard was earning = $10/hr

Due to lass in productivity 20% pay was cut

Amount Richard was earning after 20% pay cut = $8/hour.

After few again due to increase in productivity Diane gave a 20% raise.

To Find:

How much is Richard making now = ?

Solution:

Let the amount that Richard is making now be x

Then

x = 8+ 20% of 8

x = $8 + \frac{20}{100} \times 8$

x = $8 + 0.2 \times 8$

x = $8 + 1.6$

x = 9.6
