First, u do -9+8x-4+8
Then, U simplify. The answer is 8x-5
Answer:
x=8
Step-by-step explanation:
2*3x=6x
2*-7=-14
6x-14=34
6x+14=34+14
6x=48
6x/48
x=8
Answer:



Step-by-step explanation:
a. a, b, c
Quadratic equations in standard form are written as:

The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.


b. Y-intercept
The y-intercept for a quadratic is c.
You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).


We know that c=2, so the y-intercept is c.
c. Maximum/minimum
The entire quadratic is positive, so the quadratic opens up and has a minimum.
Step-by-step explanation:
Represent Diego's age by d. Then 9d=144.
Answer:
3x + 12
Step-by-step explanation:
5x + 6(x - 2) - 8(x - 3) ← distribute parenthesis
= 5x + 6x - 12 - 8x + 24 ← collect like terms
==(5x + 6x - 8x) + (- 12 + 24)
= 3x + 12
