(1a) Do 4x and 15 + x have the same value when x is 5? How do you know?

Answers

Answer:

Yes, both have the same value ( 20) when x = 5.

Step-by-step explanation:

We have two functions:

y = 15 + x

y = 4*x

We want to see if these functions have the same value when x = 5.

Then we just need to replace x by 5 in both equations, and see if the values of y are the same

first function:

y = 15 + 5 = 20

second function:

y = 4*5 = 20

So yes, both functions are equal to 20 when x = 5.

Answer:

Yes.

Step-by-step explanation:

4(5)=20

15+5=20

what are the y-intercepts to graph the equation-4x - 3y = 36

Answers

Answer:

Y-Int = -12

Step-by-step explanation:

First, I would change the equation to slope intercept form:

-3y = 36 + 4x

3y = -36 - 4x

y = -12-4/3x

y = -4/3x - 12

-12 is the y-intercepts to graph the equation-4x - 3y = 36

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The given equation is -4x-3y=36

Now let us convert the given equation to slope intercept form y=mx+b

where m is the slope and b is the y intercept

Isolate the term y

-3y=36+4x

Divide both sides by 3

-y=36/3+4/3x

Multiply both sides by -

y=-12-4/3x

y=-4/3x-12

Slope is -4/3 and y intercept is -12

Hence, -12 is the y-intercepts to graph the equation-4x - 3y = 36

Children 12 and under eat free at a local restaurant. If x represents age, write an inequality to represent people who do not get a discount.

Answers

Answer:

12 ≤ x

Explanation:

Kids 12 and under, meaning that the age of someone who enters the restaurant has to be less than or equal to 12 to eat free

The inequality which represents the age of the people who do not get the discount is x > 12.

What is Linear Inequalities?

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Given that,

Children 12 and under eat free at a local restaurant.

Let x represents the age of the people.

Since the children who are 12 and under will get the discount, the age of the people who do not get the discount is the people with age greater than 12.

That is the inequality representing this situation is,

x > 12

Hence the required inequality is x > 12.
