Answer:

y = -1/3x

Step-by-step explanation:

To find the slope of the line, you can take two points and use the slope formula.

-2 - 0 = -2, 6 - 0 = 6, -2/6 =  -1/3 which is the slope.

You would usually need to find b in y = mx + b but here you don't need b due to their being no y-intercept.

So just substitute -1/3 into y = mx + b

Which facts could be applied to simplify this expression? Check all that apply.
tensa zangetsu [6.8K]

Answer:

The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.

C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.

D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.

Mama L [17]

Answer:

<h2>The inequality r – 34 > 3 can be used to represent the situation. </h2><h2>The raised temperature could be 40 degrees. </h2>

Step-by-step explanation:

The choices are

  • the inequality r + 3 > 34 can be used to represent the situation.
  • the inequality r – 34 > 3 can be used to represent the situation.
  • the raised temperature could be 40 degrees.
  • the raised temperature could be 37 degrees.
  • the graph of the solution set would be shaded to the left.

Notice that the inequality which represents this situation is

r>34+3

Because the temperature increases more than 3 degrees.

So, the second choice is correct, because it's the expression that represents the problem.

Now, the initial temperature of the refrigerator was 34°, if it increases more then 3 degrees, it means the temperature can be greater than 37°, therefore, the third choice is correct, because 40° is greater than 37°.

At last, the graph of the inequality is shaded to the right, because the inequility symbol is "greater than".

Alja [10]
If Ayana gave 1/5 of the peanuts to her sister and then 3/4 of what remained to another sister, she kept 1/5 for herself. It's because:

5/5 is what she got at the beginning
5/5 - 1/5 = 4/5 is what she gave to one sister
3/4 of what remained is 3/4 * 4/5 = 12/20 = 3/5 for another sister

So now 4/5 - 3/5 = 1/5 is what she kept for herself.
