In order to do this you have to substitute b with 9 and get 3a+9=54, now subtract 9 from both sides to leave a by itself and get 3a=45, now divide 3 in both sides to leave a by itself and get a=15
Hope this helps
if x is changed by 2 , the y changes by +3, Option B is the correct answer.
<h3>What is the equation of a Linear Function ?</h3>
The equation of a Linear Function is given by
y = mx +c
here m is the slope , c is the intercept on the y axis
The data is given in the table
To determine the relation , a function needs to be established between the variables.
m = ( y2 -y1 )/(x2-x1)
m = (-7 +10) /(-2+4)
m = 3 / 2
y = (3/2)x + c
at x = 0 , y= -4
-4 = 0 + c
c = -4
The function is
y = (3/2) x - 4
if x is changed by 2 , the y changes by +3
Therefore Option B is the correct answer.

427+316
step one- add 400 and 300=700
step two- take 3 from the 16 and add it to the 27 and add - 27+3+13=43
step three- add 43 and 700
I think that the common core way just adds more steps and makes it more complicated than just adding it regularly, but that's just me.
Answer:
We know that the sum of the first two sides is greater than the largest side.
7 + 11 > x
x is the third side.
18 > x
x < 18
The sides of the triangle are 7, 11, and 17.
The product = 7 × 17 = 119
