Answer:
Step-by-step explanation:
(2+10)/(5+1)= 12/6 =2
y + 10 = 2(x + 1)
y + 10 = 2x + 2
y = 2x - 8
Answer:
B. 9 : 21
Step-by-step explanation:
Multiply numerator and denominator by 3:
... 3/7 × 3/3 = 9/21 ⇒ 9 : 21
_____
Any denominator that is not a multiple of 7 will not work. 35 is a multiple of 7 (=5×7), but 12 (=4×3) is not the same multiple of 3.
Answer:
x<3
where x does not exist
(-infinity, 3)
Where x exists
[3, infinity]
Step-by-step explanation:
I'm just going to answer the first one.
Treat it like your solving for x, however the only difference is that it's an inequality.
3x-2 <7
3x< 7+2
3x/3x < 9/3
x<3
Now we know where x does and does not exist.
I'm assuming your teacher wants that, (-infinity, 3) (this is where it does not exist)
[3, infinity]
In case you were wondering square brackets is where it exists and curled is where it doesn't.
The answer is D becuase 18 plus 6 is twenty four
