Answer:
x = 2
Step-by-step explanation:
Solve the two equations simultaneously....whereby you substitute y = 2x - 6 from the above equation into the second equation...
where...; 5x + 10(2x - 6) = -10
5x + 20x - 60 = -10...then move the variables with x to one side...
5x + 20x = -10 + 60
25x = 50
;Therefore...the value of x at intersection point = 2
Answer:
The less sign looks like a weird L the greater sign looks like a backwards L the equal sign means the two sides are equal. I hope this is the answer you were looking for

Answer:
111 1/9 pounds
Step-by-step explanation:
The given relationship is ...
delivered = ground × (1 -10%)
Then ...
ground = delivered/0.90 = 100 lb/0.90 = 111 1/9 lb
It is necessary to grind 111 1/9 pounds of grain to have exactly 100 lb after a 10% payment.
4 to the second power. Just find the squared root of 16
The period of oscillation of a pendulum is
Where L is the length of the pendulum and
the gravitational acceleration.
Re-arranging the formula and using T=1.0 s, we find the length of the pendulum:
