Answer:
(3 ⋅ x) - (-1/2)
Step-by-step explanation:
Since it says the product of 3 and a number, it can be written as 3 ⋅ x, where you need to multiply 3 by x, and it only says “a number” so you can just put x. Then, it says the difference of that product and -1/2. Now, you can put the product part in, which is 3 ⋅ x, and subtract that with -1/2 to get (3 ⋅ x) - (-1/2)

Mr. Vitorello spends 35% of his salary on rent. He makes $2,500 each month. How much does he spend on rent each month?
Answer: He spends 875 a month on rent.
Step-by-step explanation:
35 x 2500 = 87500
87500 / 100 = 875
Hope this helps :)
Answer:
He spends $10,500
Step-by-step explanation:
Since salary is yearly we multiply 2500 by 12 and we get 30000
And 35% of 30000 is 10500
John has $5 in his bank account when he gets a job. He begins making $109 a day. A student found that the equation that represents this situation is y = 5x + 109.
Answer:
the student answer is incorrect
Correct answer: y = 109x + 5
Step-by-step explanation:
He STARTS with $5, which means it says aside. Since he REPEATEDLY recieves $109 EVERY day, it is as 109x because you don't know how much days there are. So the correct equation is y = 109x + 5.
Hope this helps!

A model of a skyscraper uses the scale of 2 inches = 45 feet. If the actual skyscraper is 992 feet tall, how tall is the model?
Answer:
44.08 or 44.1
Step-by-step explanation:
OK so the basics of this question is that for every 45 feet of the actual skyscraper we have 2 inches in the model. The first thing we do is divide 992/45 which equals 22.04. Know if this was 1 inch for every 45 feet we would be done however we need to multiply this number by 2 to get our answer so 22.04*2 =44.08

What is the slope-intercept equation of the line that goes through the points (3,5) and (-1,13)
Answer:
y=-2x+11
Step-by-step explanation:
Slope-intercept form is y=mx+b.
Slope is rise/run, which is y2-y1/x2-x1. Using these points, that's (13-5)/(-1-3). This is 8/-4, or -2.
You can plug this into y=mx+b to get y=-2x+b.
To solve for b, you can use one of the original points and plug it back into the formula:
y=-2x+b
5=-2(3)+b
5=-6+b
b=11
So, putting it all together, you get y=-2x+11.
Simonne used the following steps to simplify the given expression.
Mark bought gifts for his friends, and each gift cost $9. Let y represent the total cost and represent the number of gifts. Write an equation to represent the proportional relationship between the total cost and the number of gifts he bought. (4 points) Oy=8x a 1 y = 8 x Oy=9x O 1 y = 9 x
Answer:
y=9x (O 1)
Step-by-step explanation:
9 times the number of gifts he bought which lets say is x will equal your answer (y).
i need help please!! its math !
Answer:
perimeter = 2(8x+3) + 2(5) area= (8x+3) • 5
Step-by-step explanation:
perimeter = 2(length) + 2(width)
if length equals (8x+3) and width equals 5 then you would just plug those numbers into the equation which gives you...
perimeter = 2(8x+3) + 2(5)
area = length • width
like i previously said above if length equals (8x+3) and width equals 5 than you would just plug those numbers into the equation which gives you...
area = (8x+3) • 5
how can you tell whether or not a figure is a scaled copy of another figure?
Answer:
If they are divisible by the numbers in the original shape, then try and see if the others sides of the scaled copy are scaled by the same factor. If they are, then they are a scaled copy.

A. 0,0) is the x- and y-intercept of the function
B. 0,1) is the x- and y-intercept of the function
C. This function has no intercepts
D. 1,1) is the x- and y-intercept of the function
Answer: A is correct
Step-by-step explanation:
The graph shows the square root of the parent function and function has no intercepts
What is the parent function?A parent function is the simplest function that still satisfies the definition of a certain type of function. For example, when we think of the linear functions which make up a family of functions, the parent function would be y = x. This is the simplest linear function.
What are intercept?Using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.
According to the question
Graph shows the square root of the parent function.
i.e ,
y = [tex]\sqrt{x}[/tex]
As,
This equation will never touch the x-axis or the y-axis, so the function does not have an x- or y- intercept.
Therefore,
This function has no intercepts ,
Hence, The graph shows the square root of the parent function and function has no intercepts .
