Answer:
Substitute the x and y values from the ordered pairs into the equation, one by one, until both sides of the equation are equal.
Step-by-step explanation:
A. (-2,-3)
3 * (-2) - 4 * (-3) = 21
-6 + 12 = 21
6 = 21 <u>not equal</u>
B. (0,7)
3 * 0 - 4 * 7 = 21
0 - 28 = 21
- 28 = 21 <u>n</u><u>o</u><u>t</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>l</u>
C. (7,0)
3 * 7 - 4 * 0 = 21
21 - 0 = 21
21 = 21 <u>equal</u>
Answer: yes your right
Step-by-step explanation: i used it it was right
1/3 x 4/4 = 4/12
4/12 + 5/12 = 9/12
12/12 - 9/12 = 3/12
3/12 = 1/4
Answer:
Step-by-step explanation:
This is an order of operations question. First in PEMDOS you want to do your parenthesis, turn (5-2) into 3,
15 ÷ 3 + 4
Then do your divison, turning 15 ÷ 3 into 5
5 + 4
Then finish with 5 + 4
The answer is 9
the exact value of 0.428x2.75 is 1.177, in order to get this you multiply both number with each other.
