Answer:
it's A- (12,8)
Step-by-step explanation:
i looked on desmos I'm not completely sure if this is the correct answer or not cause when i was looking at the graph none of them exactly lined up with S so I chose the one closest to aligning :p
Answer:
x - 9 = 19 x = 28
8y -5x = 16 idk but what i do know is this...
Step-by-step explanation:
8 x 5 - 5 x 5 = 15 & 8 x 4 - 5 x 3 = 17
so if u want to try to put in some numbers u might find it.
but it would be better if i had answer choices.
Answer:
20 pounds / in^2
Step-by-step explanation:
Presssure = Force in pounds / Area in square inches.
Force: 60 pounds (given)
Area: 3 in^2 (given
Pressure = 60/3 = 20 pounds / square in
Two equal roots means a discriminant of zero.
(k + 2)x² + 4k = (4k + 2) x
(k + 2)x²- 2 (2k + 1) x + 4k = 0
When we have an even linear term it's easier to generate 1/4 of the usual discrimant,
0 = d/4 = (b/2)^2 - ac = (2k + 1)² - 4k(k+2) = 4k² + 4k + 1 - 4k² - 8k = -4k + 1
4k=1
k=1/4
Answer: k=1/4
Check:
(k + 2)x² + 4k = (4k + 2) x
(9/4)x² - 3x + 1 = 0
9x² - 12x + 4 = 0
(3x - 2)² = 0
A perfect square, two equal roots, good
