Answers
they will reach at the same time.
Step-by-step explanation:
first we need to find out total Miles covered by bus and truck per hour,
so,
300÷6=50 miles per hour
200÷4=50 miles per hour
so they both will reach at the same time.

Use elimination to solve the system of equations given by 3x - 2y = 10 and 5x + 2y = 6
Answers
Answer:
x = -2 y= -8 and 8
Step-by-step explanation:
Since there is an equal number of y's, they cancel out when subtracting. You can put either equation on top. You will get same answer.
To find x:
If you do (3x - 2y = 10) - (5x + 2y = 6), you will get -2x=4. Divide both sides by -2, and get x = -2.
If you do (5x + 2y = 6) - (3x - 2y = 10), you will get 2x=-4.Divide both sides by 2, and get x = -2.
To find y:
Substitute -2 for x in either equation. It doesn't matter.
For 3(-2) - 2y = 10:
3(-2) - 2y = 10 ––Multiply
-6 - 2y =10 ––Add 6 to both sides to get y alone
-2y = 16 ––Divide by -2
y = -8
For 5x + 2y = 6:
5(-2) + 2y = 6 ––Multiply
-10 + 2y = 6 ––Add 10 to both sides to get y alone
2y = 16 ––Divide by 2
y = 8

Bill purchases a bond for $1,200. It pays 7% simple annual interest and matures in 8 years. How much interest will Bill earn
after the bond reaches maturity?
Answers
Answer:
672
Step-by-step explanation:
I'm going to assume that this is a zero-coupon bond
simple interest is as follows
PV(1+it)
we have
1200(1+.07*8)
1200*1.56=1872
This is the accumulated value
to find the interest earned we use the following equation
AV-PV
we have
1872-1200=672

What is the y-intercept of y = –2x+6?
Answers
Answer:
thw y intercept iz 6 and the z
slope is -2x
Step-by-step explanation:
hope this helps
Answer: y = 6
Step-by-step explanation:
1. Let y = 0 to find the x-intercept(s).
0=-2 x +6
2. Subtract 6 from both sides.
- 6 = - 2 x
3. Divide both sides by -2.
-6/-2 = x
4. Two negatives make a positive so 6/2 = x
5. Simplify 6/2 to 3.
3 = x
6. Switch sides.
x = 3
2. y-Intercept
1. Let x = 0 to find the y-intercept(s).
y = -2 x 0+6
2. Simplify and get y = 6
