Answer:

<em> 3(x+y)+15xy</em>

<em></em>

Step-by-step explanation:

Write an algebraic expression for the verbal expression: three times the sum of X and Y increase by five times the product of x and 3y.

Sum of x and y = x+y

three times the sum of X and Y = 3(x+y)

product of x and 3y  = x(3y) = 3xy

five times the product of x and 3y = 5(3xy) = 15xy

<em>Three times the sum of X and Y increase by five times the product of x and 3y will be expressed as;</em>

3(x+y) + 15xy

<em>Hence the required algebraic expression is 3(x+y)+15xy</em>

<em></em>

The table when completed looks like this:

x   -2   -1   0   1   2

f(x) 4   2   1    2   4.

We plot these points on the graph: (-2, 4), (-1, 2), (0, 1), (1, 2), (2, 4).

<h3>What is a function?</h3>

A function exists as a relation between a dependent variable (f(x)) and an expression of an independent variable (x), utilized to define the value of a dependent variable from a provided value of an independent variable.

We have been given a function,

$f(x)=\left \{ {{(1/2)^{x},x\leq 0 } \atop {2^x > 0}} \right.

We have to estimate the value of f(x) when x = {-2, -1, 0, 1, 2}

If the values of x ≤ 0, take f(x) = (1/2)ˣ then

f(-2) = (1/2)⁻² = 2² = 4

f(-1) = (1/2)⁻¹ = 2¹ = 2

f(0) = (1/2)⁰ = 1

If the values of x > 0,  take f(x) = 2ˣ then

f(1) = 2¹ = 2

f(2) = 2² = 4

The table exists as follows

x   -2   -1   0   1   2

f(x) 4   2   1    2   4.

We plot these points on the graph: (-2, 4), (-1, 2), (0, 1), (1, 2), (2, 4).

Which statement is true?
alexgriva [62]
The Correct answer is C. -14 + (-10) = -24 and 2 + (-28) = -26. When negative numbers are in play, the lower negative number is higher in value. So when solved -24 > -26
