Answer:
y =
Step-by-step explanation:
with the point slope form, plug -9 (x coordinate) into x1, -3 (y coordinate) into y2, and -4/3 (slope) into m
y - y2 = m(x - x1)
y - (-3) = -4/3 (x - (-9))
y + 3 = -4/3 (x + 9)
y + 3 = -4/3 x + -12
y = -4/3 x - 12 - 3
y =
Answer:
(1.5,0)
(.5,0)
Step-by-step explanation:
Quadratic formula below
We first need to move everything to one side of the equation
4x²-8x+3=0
Then plug everything in
(8±√(-8²-4*4*3))/(2*4)
(8±√16)/8
To calculate the ± we need to do when where it's adding and then negative
we have
(8+4)/8=3/2
and hten
(8-4)/8=1/2
Answer:
d
Step-by-step explanation:
convert 6/10 to the same denominator as the other fraction (100) by multiplying the entire fraction by 10 resulting in 60/100 then add 16/100
Answer:
12
Step-by-step explanation:
x = - 9
f ( x ) = - 3 l x + 5 l
f ( - 9 ) = - 3 l - 9 + 5 l
= - 3 l - 4 l
= - 3 * 4
f ( - 9 ) = 12
28 divided by 8 is equal to 3.5, so one hotdog will cost $3.50
