Answer:
11 years old
Step-by-step explanation:
If four brothers have the average age 6, then the sum of their ages is
years.
Let x years be the age of sister. If four brothers and their sister have the average age 7, then
Multiply this equation by 5:
The sister is 11 years old.
Step-by-step explanation:
We have been given an equation y+6=45(x+3) in point slope form.
It says to use the point and slope from given equation to create the graph.
So compare equation y+6=45(x+3) with point slope formula
y-y1=m(x-x1)
we see that m=45, x1=-3 and y1=-6
Hence first point is at (-3,-6)
slope m=45 is positive so to find another point, previous point will move 45 units up then 1 unit right and reach at the location (-2,39).
Now we just graph both points (-3,-6) and (-2,39) and join them by a straight line. Final graph will look like the attached graph.
Pretend to (or actually) cut out the given image, stick a pin in point P so it cannot move, and rotate the cutout up and to the left around point P about 1/8 of the way around the circle. The result of doing that is the picture you're looking for.
