Answer:
5x + 16
Step-by-step explanation:
combine like terms (x) 12 + -7 = 5
so 5x + 16
leave the 16 because there is not like term to combine it with and you don't have a y to finish solving the equation
final answer: 5x + 16
hope this helps

Step-by-step explanation:
Givens
Let the smallest integer = x - 1 (You'll see why in a moment).
Let the middle integer = x
Let the largest ingeger = x + 1
Equation
x - 1 + x + x + 1 = 255
Solution
Combine like terms on the left.
3x - 1 + 1 = 255
3x = 255 Divide by 3
3x/3 = 255/3
x = 85
So the smallest number is 84
The middle number is 85
The largest number is <u> 86</u>
Total 255
Do you see why I made the smallest number x - 1?
It is because the -1 and the plus 1 cancel out.
Please realize the question says consecutive integers. It does not say consecutive odd or consecutive even integers.
Answer:
<em>D. is zero</em>
Step-by-step explanation:
<u>Graph of the Parabola</u>
The quadratic function's graph is called a parabola. There is a clear relationship between the roots of the equation and the shape of the parabola.
If the equation has two real roots, the parabola has two x-intercepts. If the equation has only one real root, the parabola crosses the x-axis only once, and if the equation has no real roots, the parabola never crosses the x-axis.
If the equation of the parabola is
Then the so-called discriminant is
If the discriminant is zero, the equation has only one real root. The graph in the image only goes through the x-axis once.
Thus, the correct answer is
D. is zero

Enter the following numbers in the boxes provided sequentially.
First box : 7
Second box: 2
Third box: 3
Fourth box : 4
Fifth box: 8
Sixth box: 3
Answer:
4. z = -1
5. x = 3.5 or 7/2
Step-by-step explanation:
4.
-4z + 8 = 7z +14 + 5
-4z + 8 = 7z + 19
8 = 11z + 19
-11 = 11z
-1 = z
5.
6-x/5 = 6-3x+6/3
6-x/5 = 12-3x/3
18 - 3x = 60-15x
-3x = 42 - 15x
12x = 42
x = 3.5 or 7/2
