Answer:
Slope = -2
Step-by-step explanation:
slope = (y₂ - y₁)/(x₂ - x₁)
s = (6 - 0)/(-3 - 0)
s = 6 / -3
s = -2
I hope this helped and please mark me as brainliest!
To expand the given expression we proceed as follows:
(6x²-2x-6)(8x²+7x+8)
=6x²(8x²+7x+8)-2x(8x²+7x+8)-6(8x²+7x+8)
=48x⁴+42x³+48x²-16x³-14x²-16x-48x²-42x-48
putting like terms together:
48x⁴+(42x³-16x³)+(48x²-48x²)+(-16x-42x)-48
=48x⁴+26x³+0x²-58x-48
hence the answer is:
48x⁴+26x³-58x-48
1 * 60 * 60 = 3600 (seconds in 1 hour)
3600 * 6 = 21600 (seconds in 6 hours)
3600 * 0.4 = 1440 (seconds in 0.4 hour)
21600 + 1440 = 23040 (6 hours + 0.4 hours)
your answer is 23040
Answer:
Step-by-step explanation:
Rachel worked for 3 2/3 hours.
Multiply the fractions to get the answer.
2 3/4 x 1 1 /3 is 3 2/3.
Hope it helps you :D
-4.5x-2y=-12.5 and 3.25x-y=-0.75
we first multiply the second equation by -2
(-2)*(3.25x-y=-0.75)=-6.5x+2y=-1.5
add the equation to eliminate the y
so yo get (-4.5x-6.5x)=(-12.5-1.5)
-11x=-11
x=1
now we plug in x into any equation to solve for y
-45x-2y=-12.5 and x=1
(-45*1)-2y=-12.5
-4.5-2y=-12.5
-2y=-12.5+4.5
-2y=-8
y=4
then your answer is x=1 and y=4
