Answer:

the answer is C

Step-by-step explanation:

by doing the distributive property

multiplay the -3 with the numbers in the parenthesis (2x-5) and the same with -2 and (4x +3)

the result will be -6x+15-8x-6 now you need to combine like terms

-6x-8x 15-6

-14x+9

Dion need 25% more cookies and Cameron they saw the cookies for $.50 each let X represent the number of cookies Cameron made whi

nataly862011 [7]

Answer:

For this case we have the following variable:

x: the number of cookies Cameron made.

Therefore, the number of cookies Deyonne makes is:

(x + 0.25x)(x+0.25x)

Then, the total sales revenue is:

P = 0.5 * (x + (x + 0.25x))P=0.5∗(x+(x+0.25x))

Rewriting we have: P = 0.5 * (2.25x)P=0.5∗(2.25x)

P = 0.5 * (2.25x)P=0.5∗(2.25x)

P = 1.125xP=1.125x

Help me the questions and answer choices are in the picture

Using the Triangle Inequality Theorem

The sum of two side lengths of a triangle is always greater than the third side

first one: 6, 22 , 10
6 + 22 > 10 : yes
22 + 10 > 6 : yes
6 + 10 > 22 : No because 16 < 22
These 3 lengths could NOT be lengths of sides of a triangle

second one: 8 , 15 , 22
8 + 15 > 22 : yes
15 + 22 > 8 : yes
8 + 22 > 15 : yes
These 3 lengths could be lengths of sides of a triangle

Answer:
Second option
8 cm, 15 cm, 22 cm

It takes a total of 6 hours to fill up an inground backyard pool using a standard hose. A function can represent this situation

ValentinkaMS [17]

At time t = 0 the pool is empty. At time t = 6 hours the pool is full. Once you have a function that represents the amount of water in the pool, you should be able to put any value for t in the domain 0 <= t <= 6 to find the amount of water in the pool. t can be any real number such as: 1, 1.5, 2.8, 3.6589, etc. So all real numbers from 0 to 6 hours.

The system of linear equations -2x+y=8 and -3x-y=7 is graphed below. What is the solution to the system of equations? (–3, 2) (–

Slav-nsk [51]

Answer:

x = -3 , y = 2

Step-by-step explanation:

Solve the following system:

{y - 2 x = 8 | (equation 1)

{-3 x - y = 7 | (equation 2)

Swap equation 1 with equation 2:

{-(3 x) - y = 7 | (equation 1)

{-(2 x) + y = 8 | (equation 2)

Subtract 2/3 × (equation 1) from equation 2:

{-(3 x) - y = 7 | (equation 1)

{0 x+(5 y)/3 = 10/3 | (equation 2)

Multiply equation 2 by 3/5:

{-(3 x) - y = 7 | (equation 1)

{0 x+y = 2 | (equation 2)

Add equation 2 to equation 1:

{-(3 x)+0 y = 9 | (equation 1)

{0 x+y = 2 | (equation 2)

Divide equation 1 by -3:

{x+0 y = -3 | (equation 1)

{0 x+y = 2 | (equation 2)

Collect results:

Answer: {x = -3 , y = 2
