Calculate the x-intercept for the equation 6x - 9y = 18

Find the slope, m and y-intercept for the equation -20x + 5y = 30

In blending two different gasolines with different octanes, in order to find the number n of liters (L) of one octane needed, the equation 0.10n + 0.07(2,000 - n) = 0.10(2,000) is used. Find the value of n.

1. The voltage drop across a resistor is found by multiplying the current I (in Amperes, A) and resistance R (in ohms, ?). Find the possible voltage drops across a variable resistor R, if the minimum resistance is 1,500 ?, the maximum resistance is 3,000 ?, and the current is constant at .0020 A. Represent the final result as an inequality?
2. Write the slope intercept form of the equation of a linear function that has a slope of - 5 and crosses the y axis at 8.
3. Find the slope and y-intercept of 12x + 4y -8 = 0.
4. If possible, evaluate the function f(t) = - 2t² - 2t - 1 for f (3).
