6a+16

Explanation:
If there's just a variable, there's an understood 1 in front of it. So what that really says is:

7a-1a+16

So, you combine the a's. 7a minus 1a is 6a. Same as 7-1,but you have a variable stuck on the end of it.

6a+16

X=7w^+4w-6 and y=w^-11w+13
aleksandr82 [10.1K]
Although the terms might seem intimidating, this is a simple substitution problem.

X + Y = _______
Substitute the values of X and Y in terms of w
(7w^2 + 4w - 6) + (w^2 - 11w + 13) = ______
Now all you need to do is combine like terms (terms that have the same variables raised to the same power)
8w^2 - 7w + 7

Final Answer: 8w^2 - 7w + 7

Based on the data table, which equation accurately represents the situation?
8090 [49]

Answer:

The equation of the line is:

y = 28x

Hence, option C is correct.

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the table

Gallons               Miles Driven

8                          224

10                         280

4                           112

Finding the slope between any two points, let say (8, 224) and (10, 280)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(8,\:224\right),\:\left(x_2,\:y_2\right)=\left(10,\:280\right)

m=\frac{280-224}{10-8}

m=28

now substituting (8, 224) and m = 28 in the slope-intercept form of line equation

y = mx+b

224 = 28(8) + b

224 = 224 + b

b = 0

Thus, the y-intercept b = 0

now substituting b = 0 and m = 28  in the slope-intercept form of line equation

y = mx+b

y = 28x+0

y = 28x

Therefore, the equation of the line is:

y = 28x

Hence, option C is correct.
