Answer:

-10.

Step-by-step explanation:

Step 1: Explain/define

This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.

P (Parenthesis)

E (Exponents)

M/D (Multiplication/division, whichever comes first)

A/S (Addition/subtraction, whichever comes first)

This is the correct sequence of steps when solving expressions with multiple operations.

PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."

------------------------------------------------------------

Step 2: Solve.

REMEMBER PEMDAS!

Expression given: 4 × 3 + 2 × 9 - 40

There are no parentheses.

There are no exponents.

There is multiplication, but no division.

4 × 3 + 2 × 9 - 40

12 + 18 - 40

There is addition and subtraction. Remember to solve whichever comes first.

12 + 18 - 40

30 - 40

30 - 40 = -10.

I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.

Please let me know if you have any further questions.

Amir says the graph of<br> y= x2 + 16 has -4 as a zero. Is Amir correct?<br> Explain.
sukhopar [10]

Answer:

  • Amir is wrong

Step-by-step explanation:

The function y = x² + 16 is positive for any value of x, hence the graph has no intersection with the x-axis and therefore has no real zero's.

If no zero's, -4 also can't be its zero.

Enter a recursive rule for the geometric sequence. 10, −80, 640, −5120, ...<br><br> a(1)=<br> a(n)=
Liula [17]
The recursive formula would be:
a_1=10&#10;\\a_{n}=a_{n-1} \times (-8)

This is because the first term, a₁, is 10.  A recursive rule is dependent upon the term before it (a(n-1)) and the common ratio.  The common ratio, or the number that each term is multiplied by, is -8.
