Let's solve for a.(−a)(x)+4b>9Step 1: Add -4b to both sides. −ax+4b+−4b>9+−4b −ax>−4b+9
Step 2: Divide both sides by -x. −ax−x>−4b+9−x a<4b−9x

HOW DO I DOOO THISS IDEK!!!!! HELLLPPPPP

Airida [17]

Unit rate of change is 60, because he's paid 60 dollars an hour. This is found by dividing his profit by hours worked, so for example on day one he worked 5 hours and received 300 dollars. 300/5=60. The equation for the graph would be y=60x [money paid = $60 x (hours)]

If x²+(c-2)x-c²-3c+5 is divided by x+c the reminders is -1 find the value of c ?

frosja888 [35]

Answer:

c = 3

Step-by-step explanation:

A polynomial f(x) divided by (x + c) has remainder f(- c)

Substitute x = - c into the polynomial and equate to the remainder - 1

(- c)² + (c - 2)(- c) - c² - 3c + 5 = - 1 , simplify left side

c² - c + 2c - c² - 3c + 5 = - 1 , collect like terms on left side

- 2c + 5 = - 1 ( subtract 5 from both sides )

- 2c = - 6 ( divide both sides by - 2 )

c = 3

Look at the table. Make a conjecture about the sum of the first 15 positive even numbers.

Olenka [21]

Be observing the table, we can write the following conjecture:

When adding consecutive even numbers, starting from 2 to $m$ .

Then the sum is equal to:
$\frac{m}{2}( \frac{m}{2} +1)$

Then, the sum of the first 15 positive even numbers (which is the sum of 2 to 30) can be calculated with the previous conjecture by setting $m=30$ :
$\frac{m}{2}( \frac{m}{2} +1)=\frac{30}{2}( \frac{30}{2} +1)=(15)(16)=240$

The answer is 240.
