Yes and for a. You can just put y=x [y=1x is bascually the same but just the 1 isnt needed]
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>
B. is reasonable because 9.2×4.8 = 44.16
Answer0.7
Step-by-step explanation:In math of mostly means to multiply ,so 2/10x3 1/2=0.7
Answer:
75p²
Step-by-step explanation:
Given data
We are given the expression
(196p²– 121p²)
We can see the p is common in both terms
=p²(196-121)
=p²(75)
=75p²
Hence the factorized form is 75p²
