Answer:

4=0

Step-by-step explanation:

Simplifying

(-9p + 7) + -1(-9p + 3) = 0

Reorder the terms:

(7 + -9p) + -1(-9p + 3) = 0

Remove parenthesis around (7 + -9p)

7 + -9p + -1(-9p + 3) = 0

Reorder the terms:

7 + -9p + -1(3 + -9p) = 0

7 + -9p + (3 * -1 + -9p * -1) = 0

7 + -9p + (-3 + 9p) = 0

Reorder the terms:

7 + -3 + -9p + 9p = 0

Combine like terms: 7 + -3 = 4

4 + -9p + 9p = 0

Combine like terms: -9p + 9p = 0

4 + 0 = 0

4 = 0

Solving

4 = 0

Answer:

This is How to solve a integer: Write your number on a piece of paper. You can write your integer in a variety of ways. For instance, write your integer in standard form (such as 63), expanded form (such as 100+50+2, which in standard form would be 152) or in written form (such as one thousand two hundred thirteen).

Evaluate: x(y – z) for x = 3, y = 9, and z = 2 O 33 O 45 O-21 O 21

ad-work [718]

Answer:

Step-by-step explanation:

Hi there!

We are given the expression x(y-z), and we want to evaluate it if x=3, y=9, and z=2

As we're given the values of the variables, we can substitute those values into the expression to find out what the value of the expression is.

So substitute 3 as x, 9 as y, and 2 as z in the expression above

x(y-z)

3(9-2)

Now we must follow the order of operations; start by subtracting 2 from 9 (do the stuff inside the parentheses first)

3(7)

Now multiply 3 and 7 together

21

Hope this helps!

Answer:

y varies of directly as x. This means that the equation is of the form y=kx where k is any number.

Substituting y=12 when x=4, we get

12=k×4⇒k=3

Hence, the required equation is y=3x.

The value of y when x=5 is y=3x5=15.

A sequence is defined by the function F(n) = F(n -1) +5, where n represents the number of the term for n >1, and f(1) = -4. W

Anit [1.1K]

Answer:

4th option

Step-by-step explanation:

Using the recursive rule and f(1) = - 4 , then

f(2) = f(1) + 5 = - 4 + 5 = 1

f(3) = f(2) + 5 = 1 + 5 = 6

f(4) = f(3) + 5 = 6 + 5 = 11

The first 4 terms are - 4, 1, 6, 11
