use the FOIL method: First, Outer, Inner, Last.

first: x*x = x^2

outer: x*-5 = -5x

inner: 5*x = 5x

last: 5*-5 = -25

put together: x^2 - 5x + 5x - 25

simplify: x^2 - 25

Answer:

Step-by-step explanation:

f(x)=2x^2-3x+1

f(-2)=2*(-2)^2 -(3*-2)+1

=2*4-(-6)+1

=8+6+1

6x+4=22<br><br> What is the value of x?

Hoochie [10]

X = 3

6x + 4 = 22
6x = 18 (subtract 4 from both sides)
x = 3 (divide 6 from both sides)

a hiking path is represented by the equation y=3/8x on a coordinate map. The county would like to create a parallel path for bik

stepladder [879]

Answer:

The equation of the bike path on a coordinate map is represented by $y = \frac{3}{8}\cdot x +1$ .

Step-by-step explanation:

From Analytical Geometry, we know that resultant parallel line is a translated version of parent line. Two lines are parallel to each other when they share the same slope. The resultant line can be construted from slope-point form:

$y-y_{o} = m_{\parallel}\cdot (x-x_{o})$

Where:

$x_{o}$ , $y_{o}$ - Components of known point, dimensionless.

$m_{\parallel}$ - Slope of the parallel line, dimensionless.

In addition, a line has also this form:

$y = m\cdot x + b$

Where:

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

$m$ - Slope, dimensionless.

$b$ - y-Intercept, dimensionless.

Given that parent function is $y = \frac{3}{8}\cdot x$ , the slope of the resulting line is $m_{\parallel} = \frac{3}{8}$ . Now, if $x_{o} = 16$ and $y_{o} = 7$ , we obtain the equation of the line:
