svlad2 [7]

We know that distance = rate(time). We need to solve for time here.

d = rt\\90 = 45t\\t = \frac{90}{45}\\t = 2


The car took 2 hours to travel 90 miles at a speed of 45 mi/hr

Find the slope and the y -intercept of the line.
Eduardwww [97]

Answer:

The slope is: 3

The y-intercept is: \frac{2}{3} or 0.66

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

To write the given equation in this form, we need to solve for "y":

9x - 3y = -2\\\\- 3y = -9x-2\\\\y=3x+\frac{2}{3}

Therefore, you can identify that the slope of this line is:

m=3

And the y-intercept is:

b=\frac{2}{3}=0.66

What is the product of [x-(4+13i)][x-(4+13i)]
Luden [163]

Answer:

x^2 - (4+13i)^2

Step-by-step explanation:

This product has the form (a-b)(a+b), which is a 'special product' equal to a^2 - b^2.  Following this pattern, [x-(4+13i)][x-(4+13i)] = x^2 - (4+13i)^2.  The 2nd term could be expanded if desired, but the above result is the most compact one possible.
