Take the co-ordinates of your triangle and add three to the Y co-ordinates and keep the X co-ordinates the same. Then, graph. The shape should have slid upwards three points.
To solve (8/5 + 4)7, you first have to add 8/5+4. But you cannot simply add the too because they have to be in a common denominator 'form'. To do that, we find a common denominator which is 5. We then multiply 4/1 by 5.
8/5 + 4/1= 8/5 +20/5.
Now you can solve; 8+20= 28. You leave the denominator as 5.
You get 28/5 and now you have to multiply it by 7/1. Another of saying 28/5 is 5 3/5. So 5 3/5 x 7/1= 39 2/10 (final answer)
-7 because the square root of 49 is 7 and -7
Note: I'm not going to type in case sensitive or correct grammer so it's not my fault if you paste my answer and the program says it's wrong
y=mx+b
m=slope
b=y intercept
the x intercept is where the line crosses the x axis or where y=0
the y intercept is where the line crosses the y axis or where x=0
so
for the slope, solve for y
Ax+By=C
minus Ax both sides
By=-Ax+c
divide both sides by B
the slope is
and the y intercept is at
find x intercept
set y=0
Ax+By=C
Ax+B(0)=C
Ax=C
divide both sides by A
the x intercept is at
or the point
slope is
the x intercept is at
or the point
the y intercept is at
or the point
Answer: The sales tax would be $2.40
Step-by-step explanation:
Another way of writing any percent would be diving that percent by 100, so 3% would be 0.03 4% would be 0.04 and so forth.
All you have to do is multiply 80 by the decimal of the percent
80 * 0.03 =2.4 or $2.40
