You need to find the common denominator first. 3 * 4 = 12
3/4 = 9/12 and 1/3 = 4/12
9/12 - 4/12 = 5/12
Mr. Smith has 5 children, since each of the 4 daughters share the same 1 brother.
That could be expressed in two different ways ... because
there are no parentheses in your question.
One way:
Call the number ' N ' .
Nine plus the number is (9 + N)
That much times 14 is 14(9 + N) .
The other way:
Call the number ' N '.
The number times 14 is 14N
Nine plus that is 9 + 14N .
Answer:
m= -3/2
Step-by-step explanation:
First, we must find the slope of the line given. We are given the equation:
y-2/3x=2
We must get this equation in slope-intercept form: y=mx+b (where m is the slope and b is the y-intercept). In order to do this, we must get y isolated.
2/3x is being subtracted from y. We want to preform the inverse, so we should add 2/3x to both sides.
y-2/3x+2/3x=2+2/3x
y=2+2/3x
Rearrange the terms.
y= 2/3x+2
Now the equation is in slope intercept form. (y=mx+b). 2/3 and x are being multiplied, so we know that the slope is 2/3.
Now, we have to find the perpendicular slope. Perpendicular lines have negative reciprocal slopes.
1. Negative
m=2/3
Negate the slope.
m= -2/3
2. Reciprocal
m= -2/3
Flip the numerator (top number) and denominator (bottom number).
m= -3/2
The perpendicular slope is -3/2
