I’m pretty sure that in slope intercept form it will be y-10=(0/1)(x-8)
Answer:2.8
Step-by-step explanation:add 3.5 to the 10.5 which equals 14 then you divide 5 by 14 to get the y alone and it equals 2.8
Answer:
Its value is 10.
Step-by-step explanation:
Use order of operations, PEMDAS.
The parentheses are worked out first:-
(5 - 3) X 2 + 6
= 2 X 2 + 6
Now the multiplication:-
= 4 + 6
= 10 (answer).
So first sivid 42 by 3 to get 14. Then multiply 14 by 4 to get 56. So the answer is C
