Z would be 3 because 10*3 is 30 and 30-2 would be 28 :)
5+y=x i believe let me know if that’s what you wanted :7
Answer:
the answer is B
Step-by-step explanation: Its B because the vertex is in the middle
Answer:
2 * 2 * 2 * 2
2^4
Step-by-step explanation:
16= 4 * 4 = (2 * 2) * (2* 2)
Step-by-step explanation:
when multiplied together, the gradients of the 2 graphs should equal -1 (of they are perpendicular).
x-7y=4
-7y= -x + 4
y= -1/7 x + 4/7
21x+ 3y=11
3y=-21x+11
y=-21/3 x + 11/3
-21/3 * -1/7 = 1
when multipled together, the 2 gradients dont equal -1 therefore they are not perpendicular
unless I've made a mistake with the signs at some point haha
