Answer:
Step-by-step explanation:
The dashed vertical line indicates that -3 is not included so x is greater than -3. The diagonal line is solid indicating that it is included so y is greater than or equal to -4x/5 -2. So it is second answer.
P(x) = 1x^2 + bx + c
If -bi is a root, then +bi is the other root.
Thus, p(x) = (x+bi)(x-bi) = 1x^2 + b^2

Using the distributive property, we can simplify the expression.
4 × 3 = 12
4 × = 1
4 × = -2
Here is the simplified expression:
Answer:
~ 3 1/2 days
Step-by-step explanation:
Mr.Tram travels at a constant speed of 60 km per hour, and travels for up to 8 hours per day (max). Multiply 8 with 60:
60 x 8 = 480
Next, divide 480 from 1620 to get the amount of days:
1620/480 = 3.375
~ 3 1/2 days is how long Mr.Tram will take to travel from Dallas, TX to Detroit, MI.

Answer:</h2>
First, we must determine the slope, then we find the y-intercept using slope formula and slope-intercept form.
<u>For slope:</u>
<u /><u />
Slope (m) = 7
<u>For y-intercept:</u>
<u /><u />
Y-intercept (b) = 26
Using this information, we can now create the equations for this line.
Formulas:
Slope formula: <em>y₂ - y₁/x₂ - x₁</em>
Slope-intercept form: <em>y = mx + b</em>
Point-slope form: <em>y - y₁ = m(x - x₁)</em>
<em></em>
*Note: (x₁, y₁), (x₂, y₂) = <em>2 points on the line</em>
