Simplify.
3x^2−7x+9 - 2x^2+4x−8

1. 3x^2-2x^2 = x
2. -7x + 4x = -3x
3. 9 - 8 = 1

Combine.
x -3x +1

Thus, 2x^2+4x−8 is x -3x +1 less than 3x^2−7x+9

Answer:

3 animals

Step-by-step explanation:

  1. combine like terms
  • 6 + 2x = 15 + x
  • -6   +  x   - 6  - x

     --------------------------

         3x = 9

     2. divide both sides by 3

  • 3x/ 3 = 9/3
  • x = 3

In the xy-plane, the equations x + 2y = 10 and
konstantin123 [22]

By solving given equations, the value of c is 30.

Given two equations

x + 2y = 10 and

3x + 6y = c

These lines represents the same line for some constant c.

Value of c:

x + 2y = 10-------------(1)

3x + 6y = c-------------(2)

Dividing equation (2) by 3

\frac{3x}{3}+ \frac{6y}{3} =\frac{c}{3}

After solving the above equation, we get

x + 2y = c/3-----------(3)

Remember that a line is written as ax + by = c, in our case, both lines have a =1 and b = 2. Therefore, in orther that the two lines are equal, we need that, 10 = c/3

c = 10 × 3 = 30

c = 30

Therefore,

The value of c is 30.

Ann [662]

Answer:

248.96

Step-by-step explanation:

From this regression output we have the MS Residual or mean squared error to be equal to 61983.1

the question requires us to find the standard error of the estimate. The standard error of the estimate can be gotten by finding the square root of the MSE.

\sqrt{61983.1}

= 248.96

the standard error of the estimate = 248.96

thank you!

Lisa [10]

Answer:

30+0.09x

Here, x denotes number of frosting flowers

Step-by-step explanation:

Let x denotes number of frosting flowers.

Amount charged by baker for each batch of cupcakes = $30

Amount charged for each frosting flower = $0.09

So,

Amount charged for x frosting flowers = \$0.09x

Therefore,

Total cost of a batch of cupcakes with frosting flowers = 30+0.09x
