Answer:

Yes, the answer is true.

Step-by-step explanation:

We can solve the inequality by putting x=3 and y=8 in the given inequality. This is because ordered paired inequalities are denoted by (x,y). The given inequality possess the symbols for an absolute value of a number. On a number line the absolute value is the distance between the number and zero.

So, now solving the inequality, we have:

y<|x+2|+7

8<|3+2|+7

8<|5|+7

8<5+7

8<12

Hence, the statement is true - the ordered pair (3,8) is a solution to y<|x+2|+7

Answer:

Step-by-step explanation:

When it comes to ordered pairs in inequalities, they are represented with the (x,y) values. So the ordered pair (3,8) can be substituted in the inequality $y$ .

In this inequality we have the symbols for an absolute value of a number. The absolute value of any integer will always be a positive integer as it is just the number of spaces from the origin (0,0).

So we can simply substitute the values of x and y like so:

$y$ .

$8$ .

This leaves us with 8<12 for the inequality making the statement true.

which of the following is the equation of the line that passes though the point (-2,1) and has a slope of 4

Ierofanga [76]

An equation that goes through (-2, 1) and has a slope of 4 is y = 4x + 9.

You can find this by looking for the y-intercept (b) by using the slope (m), the point and slope intercept form. The work is below for you.

y = mx + b

1 = 4(-2) + b

1 = -8 + b

9 = b

Now we can use that and the slope to create the equation y = 4x + 9

A sales person at a car dealership earns A monthly salary of $2400 and $250 for each vehicle sold how many vehicles is the sales

Ivahew [28]

Answer:

Step-by-step explanation:

Let x represent the number of vehicles that the sales person sold in a month.

The sales person at the car dealership earns a monthly salary of $2400 and $250 for each vehicle sold. Let y represent the total amount he earns for selling x vehicles in a month. Therefore,

y = 250x + 2400

To determine the number of vehicles that the sales person needs to sell in a month to earn exactly $4000, we would substitute

4000 for y. It becomes

4000 = 250x + 2400

250x = 4000 - 2400 = 1600

x = 1600/250

x = 6.4

He would have to sell 7 vehicles because he cannot sell 6.4 vehicles and if he sells 6 vehicles, it would be lesser than $4000

Jamie and Hudson took a road trip to the beach. Their total distance traveled after getting on the highway can be found using th

lukranit [14]

The total distance is an illustration of a linear function.

(1) Why the relationship is a function

The relationship is a function because all input values of h, have exactly one corresponding output value of d

(2) The function type

The function is a discrete function, because the number of hours is an integer, and it cannot take decimal values (in this case)

(3) The domain for a drive of 8 hours

The domain is the set of time the girls drive.

So, the domain is: [0,8]

(4) The range

The function is given as:

$d = 55h +10$

When h = 0,

$d = 55(0) +10 = 10$

When h = 8,

$d = 55(8) +10 = 450$

So, the range is: [10,450]

(5) The graph

See attachment

(6) The slope

A linear function is represented as:

$y = mx + c$

Where:

m represents the slope.

So, by comparison:

$Slope = 55$

The slope in this case represents the distance travelled per hour

(7) The y-intercept

In (6) above, c represents the y-intercept.

So, by comparison:

$c = 10$

The y-intercept in this case represents the initial distance
