Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
what is the equation for a line passing through (-2,3) and perpendicular to y= -1/2<em>x</em>+1 ?
Remember
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes are equal to -1)
The slope of the given line is m=-1/2
so
the opposite reciprocal is m=2
<em>Find the equation of the line in point slope form</em>
we have
substitute
<em>Convert to slope intercept form</em>
isolate the variable y
First we must get rid of the -3 in the denominator
to do this you need to multiply both sides by -3
2x - 1 <span>< -5
now add 1 to both sides
2x </span><span>< -4
finally, divide both sides by 2
x </span><span>< -2

27/x = 12/8
Cross multiply and then solve
Answer:
y = 9x + 175
Step-by-step explanation:
Choose one value for y in the table, for example, 211. All the equations have 9x, so multiply the corresponding x for 9:
9•4 = 36
Now make the value of y - 36:
211 - 36 = 175
Now you have the equation:
y = 9x +175
All you have to do to solve this problem is to put it into fraction form: if for every $4 Jo makes, Leila makes $3, then the fraction would be 3/4.
To solve this divide 60 by 4 to get 15 and then multiply 15 by 3 to get Leila's pay. 15*3=45
Check it by putting it into simplest form as a fraction to see if it checks:
45/60=3/4 and 3/4=3/4 so therefore Leila makes $45 in profit
