2(4+2x) &gt; 5x+5<br> Solve the inequality
seropon [69]

Answer:

x < 3

Step-by-step explanation:

Apply distributive property on the left of the inequality to get rid of the parenthesis:

8+4x > 5x+5

subtract 4x from both sides to group all terms with x on the right:

8 > 5x-4x+5

8 > x +5

Now subtract 5 from both sides to collect all numerical terms on the left:

8 - 5 > x

3 > x

Therefore the solution to the inequality are of those real numbers strictly smaller than 3.

The inequality can be written as x < 3 or also as we had it initially: 3 > x

Notice that the opening of the angle symbol is always facing the number 3 , meaning that 3 is the larger of the two numerical objects that are compared.

On a family vacation, Aaron took 1,276 digital photos. His twin sister Ashley took 4 times as many as Aaron. Write and solve an
aleksandr82 [10.1K]

Answer:

Equation : 4(1,276) = p

That means that Ashely took 5104 pics.

Step-by-step explanation:

Before we come up with an equation we can solve the problem and see how we solved it. If Aaron had 1,276 pics and his sister took 4 times that, we would multiply 1,276 by 4 to get how many his sister took. We don't need to do the math, but that's how we would solve it. So to find p, or Ashely's amount of pics, it's just 1,276 times 4 = p

Equation : 4(1,276) = p

That means that Ashely took 5104 pics.

Please mark brainliest if possible and have a nice day! :)

Read this, and answer the question detailed. PLEASE HURRY, I ONLY HAVE 5 MINUTES LEFT
oksano4ka [1.4K]

Answer:

no

Step-by-step explanation:

bc the  x intercept is repeating when 100 is going to two numbers.A WAY easier (and faster), way to know if it is a function is to see if there are two of the same x-intercept (which make a vertical line). If there is, then it is NOT a function.

i hope this helps
