Here is the solution based on the given situation above.
Given: 450 kg = weight limit of the elevator
750 kg = current weight of the group of passengers
? = number of passengers who weigh 70 kgs that need to get off the elevator
So to get the answer, first we need to deduct 450kg from 750 kgs to get the excess weight. So 750 - 450 is 300kgs. Next, we divide 300 by 70kgs to get the number of passengers that need to get off so 300/70 is 4.3. Therefore, there should be 4 passengers who weigh 70 kilograms that need to get off the elevator.
30.
3/4 is equal to 75%, so take 75% of 40 by multiplying .75 by 40 to get 30
Hi there!
• f(x) = 3x + 1
• g(x) = x² - 6
Then,
According to th' question :-
(f - g)(x) = f(x) - g(x)
= 3x + 1 - (x² - 6)
= 3x + 1 - x² + 6
= -x² + 3x + 7
Hence,
Option 2ⁿᵈ : -x² + 3x + 7 is Correct.
~ Hope it helps!
Answer:
x=-4 y=5
Step-by-step explanation:
3×(16-4y)+4y=8
48-12y+4y=8
-8y=-40
y=5
x=16-4×5
x=-4
2x - 3y < 12
-3y < -2x + 12...change the inequality sign because ur dividing by a negative number
y > 2/3x - 4
u have a slope of 2/3.....u have a y intercept of -4 or (0,-4)
to find the x int, sub in 0 for y and solve for x....disregard the inequality sign ....
y = 2/3x - 4
0 = 2/3x - 4
-2/3x = -4
x = -4 / (-2/3)
x = -4 * -3/2
x = 12/6
x = 2......and ur x int is 2 or (2,0)
so go ahead and plot ur intercepts (0,-4) and (2,0)....so start at (0,-4)...and since u have a slope of 2/3......go up 2 spaces and to the right 3 spaces...plot that point....then up 2 and to the right 3...plot that point...keep doing this and u will cross the x axis at (2,0)......now just draw a dashed line connecting ur plotted points
ur line will be a dashed line (because there is no equal sign in the problem)....ur shading will be above the line because it is greater then
