Answer:
x=9
Step-by-step explanation:
Isolate the variable you are solving for.
In this case, -5x needs to be divided by -5 to isolate x. But you must do to one side of the equation what you did to the other, so -45 must also be divided by -5x.
-5x/-5=-45/-5
x=9
Find the value of p and the value of q
Good evening ,
Answer:
x²-9x+12 = (x - (9/2))²- (33/4)
Step-by-step explanation:
Look at the photo below for the details.
:)
In order to find the variables p and q in the equation x^2 - 9x + 12 = (x-p)^2 - q, we first complete the square on the left-hand side which leads us to determine that p=4.5 and q=32.25.
The original equation given is x^2 - 9x + 12 = (x-p)^2 - q. To find the values of p and q, we need to rewrite the left-hand side of the equation in the format of (x-p)^2. This can be done through a process known as completing the square. Looking at the equation x^2 - 9x + 12, we have a perfect square x^2 - 9x + (9/2)^2 = (x-4.5)^2. However, remember, we added (9/2)^2 to both sides, so we have (x-4.5)^2 = x^2 - 9x + 12 + 20.25. Simplifying, (x-4.5)^2 = x^2 - 9x + 32.25, which is our original equation format. Thus, p=4.5 and q=32.25.

NEED help plz!
Answer:
y = (-3/7)x + 3
Step-by-step explanation:
As we go from (0,3) to (7,0), x increases by 7 from and y decreases by 3 to 0.
Thus, the slope of this line is m = rise / run = -3/7.
Subst. the appropriate values from this info into the slope-intercept form of the equation of a straight line:
y = (-3/7)x + 3 Note that the y-intercept is given: (0,3).
