Write an expression to represent four more than the problem of three and a number z

kicyunya [14]

$Answer:$

If the "problem of 3 and a number $z$ " is multiplying: $4+(3z)$

If it's about adding: $4+(3+z)$

$Step-by-step$ $explanation:$

Scenario A: If it's 3 and z, then that means it's 3 $z$ , and we're adding 4, so it's $4+(3z)$ (make sure to put () around the 3 $z$ !)

Scenario B: If 3 and z is also 3+ $z$ , then the equation is $4+(3+z)$ (also use () on this too!)

1 Select all relations that are functions from the choices below

Daniel [21]

Answer:

Option (D).

Step-by-step explanation:

If the graph of a relation has two output values for a single input value, relation will not be considered to be a function.

Option (A).

For the input values of x = -1, there are two output values, y = -1, 1.

Therefore, given relation is not a function.

Option (B).

Since, all the parabolas don't represent a function, given parabola in the graph is not a function.

Option (C).

Not a function. It's a relation.

Option (D).

Line plotted in the graph has a distinct output value for every input value.

Therefore, the given graph represents a linear function.

Find the product. (y - 2bs^2) (y + 3bs^2) Enter the correct answer.

Vikentia [17]

Answer:

y² + bs²y - 6b²s⁴

General Formulas and Concepts:

Expand by FOIL (First Outside Inside Last)
Exponent Power Rule: $(b^m)^n=b^{mn}$

Step-by-step explanation:

Step 1: Define expression

(y - 2bs²)(y + 3bs²)

Step 2: FOIL

First: y · y = y²
Outside: y · 3bs² = 3bs²y
Inside: -2bs² · y = -2bs²y
Last: -2bs² · 3bs² = -6b²s⁴

Step 3: Simplify

Combine: y² + 3bs²y - 2bs²y - 6b²s⁴
Combine like terms: y² + bs²y - 6b²s⁴
