Y=8-x
7=2-y
First substitute the y in the second problum for 8-x
7=2-8+x
Now subtract the 8 and the 2
7=-6+x
add the -6 on both sides to solve for x
13=x
Now substitute the x for the 13 into the first problum
y=8-13
Subtract the 13 and 8 to solve for y
y=-5
Your answer
y=-5
x=13
so your correct answer would be
B:(13,-5)
Answer:The rate of the slower hiker is 2.2 mph and the rate of the faster hiker is 5.5 mph
Explanation:
One hiker walks 3.3 mph faster than the other.
Suppose, the speed of the slower hiker is mph.
So, the speed of the faster hiker will be:
Both hikers are walking toward each other and meet in 10 hours.
We know that,
So, the distance walked by the slower hiker in 10 hours miles and the distance walked by the faster hiker in 10 hours
miles.
Given that, they were 77 miles apart in the beginning. So the equation will be
Answer:
D
Step-by-step explanation:
It crosses the y-axis at y=1 so the y-intercept is b=1.
The slope is count straight up from (-5,-2) to you are on the same horizontal level as (5,4). The rise is 6
Once you get the same horizontal level as (5,4), you will count straight over to you get to (5,4). The run is 10.
Slope=rise/run=6/10=3/5.
Or you could find slope by using the slope formula. I like to line up two pairs of points and subtract then put 2nd difference over first difference. Like so,
(5,4)
-(-5,-2)
----------
10 6
So the slope is 6/10 or 3/5 after reducing.
Slope-intercept form of a line is y=mx+b
Plug in m=3/5 and b=1
y=3/5 x +1
So the answer is D.
A quarter coin is half in value of a half-dollar coin. Therefore, two quarters makes up each half dollar coin.
Now, we know that Jessie has 14 half-dollar coins, but she needs quarters to do her laundry. Thus, if each half-dollar coin gives two quarters then 14 half-dollar coins will give quarters.
Thus, if Jessie trades all her 14 half-dollar coins for quarters, she will have 28 quarters for her laundry.
Integer,Irrational is the answer
