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

Answer:
Mary is 7
Step-by-step explanation:
If their ages combined equals 21 and john is twice Mary’s age then johns age takes up 2/3 of 21. that would b 14. 14 is 2 x 7. and Mary is 7. 14+7=21. Mary is 7 years old
Answer:
8 7/24
Step-by-step explanation:
These are mixed fractions first you need to convert them
4 5/8= 37/8
3 2/3= 11/3
Take LCM of 3 and 8 which 24.
Multiply 37/8 with 3= 111/24
Multiply 11/3 with 8= 88/24
Now add both fractions
111/24 +88/24 =199/24
This is an improper fraction. Divide 199 by 24 to change this into mixed fraction
8 7/24
