Answer:
the answer is 850 and 235
Step-by-step explanation:
you just add the numbers and multiply
Answer:
B
Step-by-step explanation:
Given the 2 equations
3x - 2y = 6 → (1)
5x + 4y = 32 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
6x - 4y = 12 → (3)
Add (2) and (3) term by term to eliminate y
11x = 44 ( divide both sides by 11 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (2)
5(4) + 4y = 32
20 + 4y = 32 ( subtract 20 from both sides )
4y = 12 ( divide both sides by 4 )
y = 3
Solution is (4, 3 ) → B
Answer:
y=10x+75
Step-by-step explanation:
Because y-y1 = m(x-x1)
Plug in the y1(5) and x1(-7)
So, y-5 = 10(x+7)
= y=10x+75
We are given displacement = 20 meters.
Time given = 4.7 seconds.
Velocity = 4.3 m/s.
Please note : Velocity is a vector quantity. A vector quantity depends on magnitude and direction as well.
We are given magnitude of displacement = 20 meter and time 4.7 seconds but the direction is missing there.
If it would be in forward direction it would be positive and if it would be in backward direction, it would be of negative.
Therefore, <u>"B)the direction"</u> is correct option.
