Answer:
b is the coefficient of the middle term. In this case, -5
Step-by-step explanation:
In a linear equation, the function is in the form of y=mx+b
In a linear equation <u>m</u> is the slope. <u>b</u> is a constant, and it is the y-intercept.
f(x) represents the "y" value obtained when a given number is plugged in to x.
In a quadratic equation, (and it would be helpful to insert a carat ^ [shift + 6] before the exponent so it is clear)
the form is a and b are the coefficients. if none, "1" is understood.
the exponent will determine the shape of the parabola.
The b will determine how far to the left or right the parent graph is transformed. ( divide by 2 and use the opposite sign)
but the c is a constant and still indicates the y-intercept.
The equation of the parallel line is y = –2x – 11.
Solution:
Given equation of the line is y = –2x – 5.
Slope of this line is = –2
To write the equation parallel to this line and passes through (–4, –3).
<em>If two lines are parallel, then they have the same slope.</em>
<u>Point-slope formula:</u>
Substitute the given values in the formula, we get
Subtract 3 from both sides of the equation.
Hence the equation of the parallel line is y = –2x – 11.
Answer:
x = 15
Step-by-step explanation:
Using the Altitude on Hypotenuse theorem
( leg of large Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )
Thus
x² = 9 × (9 + 16) = 9 × 25 = 225 ( take the square root of both sides )
x = = 15
