It’s 19. The absolute value of -7 is 7 and the absolute value of 4 is 4. 7 plus 3 times 4 is 19.

Answer:

c. 19

Step-by-step explanation:

The lines surrounding the numbers mean absolute value, which is the distance from zero. Basically what you have to remember is that if it's a positive with this symbol, you keep it the same, if a negative, you change it to positive. In this case, the I-7I would turn into a 7 and then 3*4=12. When you add 12 and 7, it equals 19. Hope this helps! :)

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Substitute in y [1st Equation]: -10x = -7x + 6
[Addition Property of Equality] Add 7x on both sides: -3x = 6
[Division Property of Equality] Divide -3 on both sides: x = -2

Step 3: Solve for y

Substitute in x [2nd Equation]: y = -10(-2)
Multiply: y = 20

Is the relation a function?

Margaret [11]

No; a domain value has two range values.

x = -2 then y = 1 and 2

they would form a vertical line, which tells us that it's not a function
