Which steps can be used to solve for the value of 'y'? 2/3(y+57)=178
bagirrra123 [75]
 2 / 3 ( y + 57 ) = 178

2( y + 57 ) / 3 = 178

2*y + 2 * 57 / 3 = 178

2y + 114 / 3 = 178

3*(2 y + 114 ) / 3 * ( 178)

2 y + 114 = 534

2y = 534 - 114

2 y = 420

y = 420 / 2

y = 210

hope this helps!

Two functions are represented in different formats. Function 1: x y 0 −2 2 0 3 1 5 3 Function 2: Graph of a line passing through
inessss [21]

The statements that are true are;

  • Function 2 has a greater rate of change than function 1.
  • Function 2 has a greater y-intercept than function 1.

Step-by-step explanation:

Given that function 1 has the table;

x  y

0 -2

2  0

3   1

5   3

Finding the slope of the linear function gives the rate of change of the function. In this case,

m=Δy/Δx

m=3-1/5-3 = 2/2 =1

The equation of the linear function is given as;

m=Δy/Δx

y-3/x-5= 1

y-3=x-5

y=x-5+3

y=x-2

y-intercept is -2

In function 2, the line passes through points (-2,0) and (0,4)

Finding the slope of the line,

m₁=Δy/Δx

m₁=4-0/0--2

m₁= 4/2 =2

Rate of change is 2

Finding the equation of the line

y-4/x-0 = 2

y-4=2(x-0)

y-4 =2x

y=2x+4

The y-intercept is 4

The statements that are true are;

  • Function 2 has a greater rate of change than function 1.
  • Function 2 has a greater y-intercept than function 1.

The volume of a square pyramid is given by the formula, V = 13hx2, where h is the height of the pyramid and x is the length of o
Vera_Pavlovna [14]

Answer: 24ft

Step-by-step explanation:

The exercise gives you the following formula:

Where "h" is the height of the square pyramid and "x" is the length of one side of the base.

According to the data given, you know that:

Therefore, you can subsitute these values into the formula:

Now, you need to solve for the "x" to calculate the length of one side of the square base of that pyramid.
