Answer:
y = 6x +2
Step-by-step explanation:
It is useful to start with the point-slope form of the equation for a line when you are given a point and a slope.
y -k = m(x -h) . . . . line with slope m through point (h, k)
y -(-22) = 6(x -(-4))
y +22 = 6x +24 . . . simplify
y = 6x +2 . . . . . . subtract 22
Answer:
The real answer to this question is B
Step-by-step explanation:
I made a 100 on my quizStep-by-step explanation:
Well you know that the total cost for the repair before any discount in both cases is $970. Company A has a 200 dollar discount so you can simply subtract 200 dollars from $970 to get $770. So you know company a will cost $770
With company B you know you are getting 15% off of the price of 970. This means to find how much you are getting off for company B you multiply 970 by 0.15 which ends up being 145.5 so company B is giving a discount of $145.50.
This means that the discount for company A is better because company A has $200 off compared to company B's $145.50
1) When you rewrite the equation as
.. y = kx^2
The value of k is 3/0.1 = 30.
2) When you rewrite the equation as
.. y = kx^2
The value of k is 6/10 = 0.6.
3) f(x) = kx^2
.. k = f(x)/x^2 = 96/4^2 = f(2)/2^2
.. f(2) = 96(2/4)^2
.. f(2) = 24
4) g(x) = kx^2
.. 98 = k*7^2 = 49k
.. k = 98/49 = 2
g(x) = 2x^2
