Step-by-step explanation:

Note that sum = (+) and greater than or equal to sign is ≥

x + 7 ≥ 15

Answer:

x = 3

Step-by-step explanation:

ok, so in this case we need to create an equation, we can do this based on the info u were given,

-it mentions "per customer" since the amount of customers is unknown we will replace that with x, 13 per customer, 13 per x so that would be 13x and it should equal the total 39 so the equation would be

13x=39

next, we need to solve and get x alone

-start by doing the opposite and dividing 13 by everything

13/13=0 it crosses out

39/13=3

so in this case, x = 3

Answer: should be

Answer:D ( if you add +4 to the (x + 3)^2)

Step-by-step explanation:

Parent function is f(x) = x^2

A translation 3 units left gives y = )x + 3)^2

- and 4 up gives y = (x + 3)^2 + 4 - vertex form.

Standard form :

y = x^2 + 6x + 9 + 4

= x^2 + 6x + 13.

The equation is of the form h= x² + 14x +58.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given:

f(x) = x²

As, graph is a translation 7 units left

f(x) = (x +7)²

and, 9 units up of the parent function

h= f(x) = (x +7)² + 9

So, equation of the form y = ax² + bx + c

h= x² + 14x +58

Answer:

39

Step-by-step explanation:

The "m" in 3(6m-17) is equal to 5, as told by m = 5. When we replace the m with 5, we get the equation

[tex]3(6*5-17)[/tex]

We get 6 × 5 because when two numbers are next to each other, it means to multiply.

In an equation, always do multiplication first (unless addition/subtraction is in parenthesis). After multiplying, we end up with

[tex]3(30-17)[/tex]

Always do whatever's in parenthesis first.

[tex]3(13)[/tex]

Now, we will multiply 3 with 13 because the two numbers are next to each other and there are no more steps to do in parenthesis.

[tex]3 * 13 = 39[/tex]

The value of the expression 3(6m-17), is 39.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The "m" in 3(6m-17) is equal to 5, as told by m = 5. When we replace the m with 5, we get the equation

E = 3(6m-17)

E = 3 ( 6 x 5 - 17 )

We get 6 × 5 because when two numbers are next to each other, it means to multiply.

In an equation, always do the multiplication first (unless addition/subtraction is in parenthesis). After multiplying, we end up with

E = 3 ( 30 - 17)

Always do whatever's in parenthesis first.

E = 3 ( 13 )

Now, we will multiply 3 by 13 because the two numbers are next to each other and there are no more steps to do in parenthesis.

E = 39

Therefore, the value of the expression 3(6m-17), is 39.
