Answer:4620
Step-by-step explanation: first you subtract the 323to the other side so you have 23423=5x now divide both sides by 5 and that’s it
Answer:
The car costs $29,500 after the value tax.
Step-by-step explanation:
First, put the percentage into decimal form. Since we are adding on the tax, add an additional 1 into the decimal.
This is what we will use to multiply with: 1.18.
We know the cost of the car, $25,000 and it's VAT, 18%.
To determine how much it will cost after the added value tax, we multiply $25,000 with 1.18 because it is an additional cost to that car specifically.
25,000 x 1.18 = 29,500
The car costs $29,500 after the value tax.

Answer:
Part 1) AJ drawn the parabola opening upwards, instead of drawing it opening downwards
Part 2) see the explanation
Step-by-step explanation:
Part 1) What mistake did AJ make in the graph?
we have

This is the equation of a vertical parabola written in vertex form
The parabola open downward (because the leading coefficient is negative)
The vertex represent a maximum
The vertex is the point (-2,-1)
therefore
AJ drawn the parabola opening upwards, instead of drawing it opening downwards
Part 2) Evaluate any two x-values (between -5 and 5) into AJ's function. Show your work. How does your work prove that AJ made a mistake in the graph?
take the values x=-4 and x=4
For x=-4
substitute the value of x in the quadratic equation

For x=4
substitute the value of x in the quadratic equation

According to AJ's graph for the value of x=-4 the function should be positive, however it is negative and for the value of x=4 the function should be positive and the function is negative
therefore
AJ made a mistake in the graph
Answer:
-2/5
Step-by-step explanation:
The slope of the line can be found by
m= (y2-y1)/(x2-x1)
= (8-10)/(36-31)
= -2/5
