Please help! 15 points to whoever graphs and solves it!

Mathematics

First you have to get the equation into slope/intercept format: y = mx + b

3y > -3+6x\\\\\frac{3y}{3} >\frac{-3+6x}{3} \\y >\frac{3(-1+2x)}{3} \\y > -1+2x\\\\y>2x-1

So the slope m = 2, and the y-intercept b = -1.

b tells you where the line intersects the y axis. The slope is rise (vertical distance) over run (horizontal distance). I have attached my best attempt at drawing this without graph paper.  The dotted line represents the inequality, and the solution set includes the values above the line which is why it is shaded. Hope this helps!

Solve these plz and give a explanation <br>​
77julia77 [94]

Answer:

\large{ \tt{☄ \: EXPLANATION}} :

✎ Firstly , Remember these things :

  • To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : 12\% =  \frac{12}{100}  = \boxed{  0.12}

\large{  \tt{☥ \: LET'S \: SOLVE}} :

\large{1. \:  \: 52\%  \: \text{of} \: 210 =  \frac{52}{100} \times 210 = 0.52 \times 210 =  \boxed{109.2}  }

\large{ 2. \:  \: 35\%  \: \text{of} \: 500 =  \frac{35}{100}  \times 500 = 0.35 \times 500 =  \boxed{175} }

\large{3. \: 28\%  \: \text{of}  \: 866 =  \frac{28}{100} \times 866 = 0.28 \times 366 =  \boxed{102.48} }

\large{ \tt{✺ \: REPEAT \: DAILY} }:

  • I will remain focused on my goals. Even if I have a moment of difficulty , I will not give up. I know Success comes with consistency. I know that I will make it. Things will get better. No problem or challenge will stop me. Everything I deserve is coming my way.

ツ Hope I helped! ۵

The side lengths 10, 14, and 15 form a triangle. Explain why.​
sertanlavr [38]

Answer:

Therefore, the side lengths 10, 14, and 15 form a triangle.

Step-by-step explanation:

The Triangle Inequality Theorem defines that if we are given the three sides of a triangle, then the sum of any 2 sides of a triangle must be greater than the measure of the third side of the triangle.

The three conditions that need to be met for any triangle with the side lengths A, B, and C.

A + B > C

B + C > A

A + C > B

Given the side lengths of a triangle

  • 10
  • 14
  • 15

Let us check whether it satisfies the three conditions.

10+15 > 14     →  TRUE

10+14 > 15     →  TRUE

14+15 > 10    →  TRUE

As all the conditions are met. Therefore, the side lengths 10, 14, and 15 form a triangle.
