Donnie is solving the equation 2x^2=27+3x with the quadratic formula. What values should he use for a , b , and c? A. a=2 b=27 c
OLga [1]
Your answer is D. a = 2, b = -3, c = -27.
This is because to use the quadratic formula, your equation needs to equal 0, and to do that, you need to subtract 27 and 3x from the right to get 2x² - 3x - 27 = 0, and since the -3 is the x value, we use it for b.

I hope this helps!

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ
leonid [27]

Answer:

y=7

Step-by-step explanation:

To calculate the standard equation of a line given two points, you need to calculate the slope and the y intercept.

The slope is the change in y variables over the change in x variables between two points.

(7-7)/(4-0)

that gives you a slope of 0, ie the line is horizontal. That means that the y value is going to be constant while the x value changes, so you can write the equation as y= y value in any point, so y=7.
