A= d+26
a-2= 2(d-2)

Substitute for a
d+26-2= 2d-4

Combine like terms
d+24=2d-4

Subtract d from both sides
24=d-4

Add 4 to both sides
d=28

Final answer: 28

Here's a graph of a linear function. Write the equation that describes that function. 8 Express it in slope intercept form. Ente
Stolb23 [73]

Answer:

f(x) = \frac{1}{2}x+4

Step-by-step explanation:

Let the equation of the function is,

f(x) = mx + b

Here, m = slope of the line

b = y-intercept

From the graph attached,

y-intercept 'b' = 4

Slope = \frac{\text{Rise}}{\text{Run}}

          = \frac{4}{8}

          = \frac{1}{2}

Therefore, equation of the function representing the graph will be,

f(x) = \frac{1}{2}x+4

Which expressions are equivalent to ? Check all that apply.
GrogVix [38]

Answer:

6.2+8.7+8.9x

Step-by-step explanation:

For expressions to be equivalent, they must simplify to the same lowest form. 8.9x+6.2+8.7 simplifies to 8.9x +14.9.

Each of the expressions below must simplify to 8.9x + 14.9 to be equivalent.

9x+6+9  = 9x + 15 NO

3.9+6.2+8.7x  = 8.7x + 10.1 NO

3.7+8.9+6.2  = 18.8 NO

6.2+8.7+8.9  = 23.8 NO

6.2+8.7+8.9x  = 8.9x + 14.9 YES

3.9+6.2x+8.7  = 6.2x + 12.6 NO

3.9x+8.7+6.2 = 3.9x + 14.9 NO
