Answer:
John takes 20 steps in 10 yards.
Step-by-step explanation:
1 yard = 36 inches
10 yards = 36 x 10 = 360 inches
Since John's step covers 18 inches, divide 360 by 18.
360/18 = 20 steps
<span>y=3x-12
2x-3y=-13
substitute </span>y=3x-12 into <span>2x-3y=-13
</span><span>2x-3y=-13
</span>2x-3(3x-12)=-13
2x - 9x + 36 = -13
-7x = -49
x = 7
y=3x-12 = y=3(7) -12 = 21 - 12 = 9
answer
solution
x = 7 and y = 9
Answer:
-26oF
Step-by-step explanation:
The difference between the low temperature and the wind-chill temperature is the result obtained when the low temperature is subtracted from the wind-chill temperature.
This difference
= -7oF - 19oF
= -26oF
The negative sign shows that there was a fall in temperature.
Answer:
None of the equations given is the equation of the function. The correct equation is: 
Step-by-step explanation:
First we must find the slope of the line that passes through these points.
The slope between two points 
and 
is given by:
where 
is the slope
In this case since we have the points: 
and 
and the slope will be:
and now we have the slope we use the slope-point equation:
