Answer:
5
Step-by-step explanation:
3(3x+7) = 3x+51
9x + 21 =3x+51 ; cuz 3 times 3 is 9 and 3 times 7 is 21
subtract 21 so 21 - 21 = 0 and 51 - 21 = 30 so
9x= 3x+30
Then subtract 3! 9-3x and 30 - 3x
You will get 6x = 30
Next you will divide by 6x
Lastly you will get 5! So your answer is 5, sorry it's a little messy but I hope this helps!
B, C, E, and F are all mathematical sentences.
we can look at the trend line, find the slope.
let's start at the start of the line, (0, 5).
the line goes up 5 units and goes right 1 unit, so that means the slope is 5/1, or 5.
so you know the slope is 5x. now let's see the y-intercept, ask yourself this, where is the start of the line ? we already answered that: (0, 5). so the y-intercept is 5.
the equation should look like y = 5x + 5, so the answer is C
