Find x given the function f(x)=4x-7 where f(x)=9

4

Step-by-step explanation:

You set f(x) = 9 and solve from there.

9 = 4x - 7

+7         +7

16 = 4x

/4     /4

x = 4

The answer is 4

Step-by-step explanation:

f(x)=4x-7

f(x)=9

9=4x-7

9+7=4x-7+7

(the -7 and the +7 cancel out, and remember: whatever you do the one side you have to do to the other)

16=4x

(divide by 4 to isolate x and do the same to the other side of the equation so you get the answer)

so, x=4

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
