Answer:

  • No, incorrect

Step-by-step explanation:

<u>Given</u>

  • Q(s) = -4s^3 + 7s^2 - 24;
  • s = -4 and 1

<u>Verifying zeroes</u>

Q(-4) =

  • -4(-4)^3 + 7(-4)^2 - 24 =
  • 256 + 112 - 24 =
  • 344
  • Incorrect as 344 ≠ 0

Q(1) =

  • -4(1)^3 + 7(1)^2 - 24 =
  • -12 + 7 - 24 =
  • -29
  • Incorrect as -29 ≠ 0

Wewaii [24]
<span>-6y + 14 + 4y = 32

Combine like terms:
-2y + 14 = 32

Take away 14 from both sides:
-2y = 18

Divide by -2 on both sides:
y = -9

Answer: y = -9 (Answer A)</span>

Find a set of parametric equations for the line of intersection of the planes x-3y+6z=4 5x+y-z=4
Inessa05 [86]

Answer:

Step-by-step explanation:

Two equations of planes are given.

We have to find the equation of the line which is formed by intersection of these two planes in parametric form

x-3y+6z=4 \\5x+y-z=4

Let us eliminate one variable

Multiply I equation by 5 and subtract II from 5 * I

5x-15y+30z=20 \\5x+y-z=4

-16y+31z=16 \\

16y+16 = 31z

Or y+1 =\frac{31z}{16}

Consider II equation

5x+y-z=4

5x+\frac{31z}{16}-1 -z=4\\5x+\frac{15z}{16}=5\\x=\frac{3z-16}{16}

Let z=z

x = \frac{3z-16}{16} and y = \frac{31z}{16}-1

The owner of a new restaurant is ordering tables and chairs. he wants to have only tables for two and tables for 4. the total nu
Papessa [141]

Answer:

4 M + 2 N = 120

Step-by-step explanation:

If we name "M" the number of tables for four people, and "N" the number of tables for two people, then the total number of people to be seated using M tables (of four people) would be the product "4 * M".

Similarly, the total number of people to be seated if the owner has N number of two person tables, would be: "2 * N".

Therefore, if the owner has M four people tables and N two person tables, the total number of people seated at the restaurant would be the addition:

4 * M + 2 * N. Since he wants this number to be 120, we complete the equation making this expression equal to 120:

4 * M + 2 * N = 120
