Answer:

The top graph

Step-by-step explanation:

The first difference is the top graph says that there are 3 pieces of data between 1-5 and the bottom says 4 pieces. There are actually 3 pieces between 1-5 so the top graph is correct.

For each ordered pair, determine whether it is a solution to y=-5x+2.
Sedbober [7]

There are two ways to do this.

The first is you plug in the x-value from the point in the table and see if that gives you the y-value from the same point.

For example, your first point is (5,49), so plug in x=5:

   y = -5(5)+2 = -25+2 = -23

Since that's not the y-value in (5,49), then (5,49) is not a solution for the equation.

The other option is you plug in both the x-value and the y-value to see if you get a true statement.  (A solution will make the equaiton a true statement.)

For example, the first point is (5,49), so you'd plug in x=5 and y=49:

    49 = -5(5)+2

    49 = -25 + 2

    49 = -23

Since that's not true, (5,49) is not a solution.

You'll notice you're basically doing the same thing, it's just whether you plug in one value or both and that's your choice.

Solve the formula V = 1/3b^2 h for b.
liraira [26]

Answer:

b=\sqrt{\frac{3V}{h}}

Step-by-step explanation:

To solve a formula for one of its variables do that

  • Underline the variable
  • Separate it on one side and the other terms on the other side
  • Make its coefficient equals 1

Let us use these steps to solve our question

∵ V = \frac{1}{3} b²h

→ Underline b

∴ V = \frac{1}{3} <u>b²</u>h

→ Multiply both sides by 3 to cancel the denominator on the right side

∴ 3V = <u>b²</u>h

→ Divide both sides by h to move it to the other side

∴ \frac{3V}{h}=b^{2}

→ To find b take √  for both sides

∴ \sqrt{\frac{3V}{h}}=\sqrt{b^{2} }

→ The square root will cancel the power 2 of b

∴ \sqrt{\frac{3V}{h}}=b

→ Switch the two sides

∴  b=\sqrt{\frac{3V}{h}}
