f is Sara's father, y is Sara, b is Sara's brother and S is sum

3y = f

b = y + 4

S = f + y + b

  = 3y + y + y + 4

  = 5y + 4

Answer:

5y+4

Step-by-step explanation:

What we know:

- 3 × y is equal to Sara's father's age

- y + 4 is equal to Sara's brother's age

- y is equal to Sara's age

Sum of their ages = father's age + Sara's age + brother's age

Sum of their ages = 3y+y+(y+4)

Sum of their ages = 5y+4

I hope this helps!

Please help m solve this it's about shaded areas. I need it fast. PLZ HELP THANK YOU IF YOU DO AND U R SO AMZING IF U DO>
sukhopar [10]

A = area of the circle

A = pi*r^2

A = pi*11^2

A = 121pi

-----

B = area of the rectangle

B = length*width

B = 6*4

B = 24

-----

C = blue shaded area

C = A - B

C = 121pi - 24 which is the exact area in terms of pi

C = 356.1327 is what you'd get if you used a calculator

C = 356.13 is the result after rounding to the nearest hundredth

<h3>The final answer is 356.13</h3>

The picture is my problem.​
Sidana [21]

Answer:

Step-by-step explanation:

Your line has the wrong slope. Its slope is ½, but the equation tells you that the slope is ¾.

The point (0,2) is correct, but (-4,0) is incorrect. If x=-4 then y=-1, not 0.

Plot (-4,-1), then draw the line passing through (-4,-1) and (0,2).

9. What is the system of equations that describes the following graph?
jeka94

The graph represented in the figure shows a set of linear equations each of which is represented a straight line.

Step-by-step explanation:

System of Equation can be referred to as an assortment of equations to be dealt with. Common examples include linear equations and non-linear equations such as a parabola, hyperbola etc.

Linear set of equations are the most simple of equation depicting a linear relationship between two variables.

E.g.  Y=4x+3

here y and x share a linear relationship which is defined by the straight-line graph "4x+3"

Similarly in the graph lines, two straight lines are depicted which symbolises that the et of the equation is linear in character.
