Step 1: Set the two equations equal to each other and solve for x.
3x -5 = 6x - 8
3x + (-5+5) = 6x -8 + 5
(3x - 6x) = (6x - 6x) - 3
-3x/-3 = -3/-3
x = 1
Step 2: To solve for y take one of the given equation of your choice (for the purpose of this explanation I will only do y = 3x - 5) and replace x with 1, then solve for y
y = 3(1) - 5
y = 3 - 5
y = -2
(1,-2)
Check:
-2 = 3(1) - 5 ---> - 2 = -2
-2 = 6(1) - 8 ---> -2 = -2
Hope this helped!
Answer:
f(- 2) = 21
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = - 5(2(- 2) + 1) + 6 = - 5(- 4 + 1) + 6 = - 5(- 3) + 6 = 15 + 6 = 21
40/2=20 half is as many their is if she has lest of seven round to the highest num because they are all even numbers
Answer:
x=2 :D
Step-by-step explanation:
first divide by -5 on both sides to get x+2=4 then subtract 2, and get x=2
Basiclaly, when will total distance equal distance they are apart
distance apart=280
distance=speed times time
assuming they travel sasme amount of time
time=t
distance=speed times time
d1=95 times t
d2=105 times t
total distance=d1+d2
280=d1+d2
280=95t+105t
280=200t
divide both sides by 200
1.4=t
