Answer:
3
Step-by-step explanation: y=10-x so 3x-2=10-x 4x=12 x=3
D looks like the best answer
Answer:
4w.
Step-by-step explanation:
Replace w with 9.
7(9)=63
4(9)=36
6(9)=54
5(9)=45
Therefore the answer is 4w.
Step-by-step explanation:
but it's given = -4
which is incorrect
Again , 8^2 = 64
but it's given = √64
so option C and D are not true
Answer:
(0,3), (1,4) (2,5) and (3,6)
Step-by-step explanation:
f(x) = x + 3 is equivalent to y = 1x + 3 (y = mx + b)
b = the y intercept, when x is 0.
So y = 3, which means its (0,3)
To check:
f(x) = x + 3
f(0) = 0 +3
f(0) = 3
(0,3)
Now let's try that for all the values (1,2 and 3)
f(x) = x + 3
f(1) = 1 + 3
f(1) = 4
(1,4)
f(x) = x + 3
f(2) = 2 + 3
f(2) = 5
(2,5)
f(x) = x + 3
f(3) = 3 + 3
f(3) = 6
(3,6)
Hope that helps!
