Mathematics
1 answer:
MArishka [77]3 years ago
3 0

Answer:

f(-3)= -8

f(2) = 4

Step-by-step explanation:

The first equation x ≤ 0 means that if the variable x, or in our case, -3, is less than or equal to 0, the answer will be calculated into the equation.

3(-3) + 1 = -8

The bottom equation x ≥ 2 means that if the variable, x, or in our case, 2 is more than or equal to 2, the answer is 4. Since 2 is equal to 2, the answer would then be 4.

susan is arranging coffee mugs on shelves in her shop. she wanta each shelf to have the same number of mugs.she only wants one c
yaroslaw [1]

The <em><u>correct answers</u></em> are:

7 mugs on each shelf; and 7 shelves for blue and 8 shelves for red.

Explanation:

To find the number of mugs that will fit on each shelf, we find the GCF (greatest common factor) of 49 and 56.  To do this, we find the prime factorization of each:

49 = 7(7)

56 = 7(8)

8 = 2(4)

4 = 2(2)

56 = 2(2)(2)(7)

The only common factor is 7, so this is the GCF.  This means that she needs to put 7 mugs on each shelf.

Since there are 49 blue mugs, she needs 49/7 = 7 shelves for them.

Since there are 56 red mugs, she needs 56/7 = 8 shelves for them.

Which equation and variable would be easiest to solve for in order to solve the system by substitution? y + x = 3 5x + 3y = -1
notsponge [240]

Answer:

Use y + x = 3 and solve for either x or y.

Step-by-step explanation:

Substitution is a method to solve a system of equations by substituting an expression from one equation into the other.

To begin, first solve one equation by isolating for one variable. Choose the equation which will have the least number of steps to do so.

y + x = 3 can be solve for x or y by subtracting the other variable. Since this only requires one step use this equation. Either variable can be used.
