commutative property
Step-by-step explanation:
You switched the numbers inside the parenthesis, which in this case is 5 and -5.
It equals 23. 3+4(5) is basically saying 3+ 4 x 5 and with PEMDAS multiplcation is done first. so 4 x 5= 20. 20 + 3= 23. Hope I helped
Answer:
1.) y = 1/2x -1.8 slope is 1/2 and y intercept is - 1.8
Step-by-step explanation:
1.) 5x - 10y = 18
<u> +10y +10y</u>
5x = 10y +18
<u>- 18 -18</u>
<u>5x - 10y</u> = <u>18</u>
<u> 10 10</u>
= 1/2x -1.8
