-7 + 8x2 - 4x
Answers
Answer: 8x^2 -4x -7
Step-by-step explanation: the x^2 term comes first, followed by the x, then the constant which in this case is -7
so it would be 8x^2 -4x -7
The polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.
To write the polynomial -7 + 8x² - 4x in descending order, we arrange the terms from highest degree to lowest degree.
Here's how to do it step by step:
Step 1: Identify the degree of each term:
The term -7 has a degree of 0 (since it is a constant).
The term 8x² has a degree of 2 (since it has a variable raised to the power of 2).
The term -4x has a degree of 1 (since it has a variable raised to the power of 1).
Step 2: Arrange the terms in descending order based on their degrees:
Start with the term with the highest degree and proceed in decreasing order. In this case, we have only three terms, so we start with the highest degree term:
8x² (degree 2)
Next, we consider the next highest degree term:
-4x (degree 1)
Finally, we have the constant term:
-7 (degree 0)
Step 3: Write the polynomial in descending order:
Putting the terms together in descending order, we have:
8x² - 4x - 7
So, the polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.

Yes that is definitely possible. You will have to either double up on geometry and algebra II or algebra II and pre-calculus. At my high school, there were multiple people that did the latter. I also knew someone that doubled up on pre-calculus and calculus I, but I don't recommend that.
Given the line below.
Write the equation of the line, in point-slope form. Identify (x1, y1) as the point (-2, 2). Use the box provided to submit all of your calculations and final answers.
Answers
The slope of that line is -1, so m = -1.
The point you were told to use is (-2,2), so point-slope form starts as:
( y - 2 ) = -1 • ( x - (-2) )
But we'd clean up that x-(-2) to be x+2.
y - 2 = -1 ( x+2 )

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends. If he works 6 hours on the weekend in addition to 35 hours during the week, how much does he earn?
Plz show work and i will be so grateful
Answers
Answer:
35 hours during week pay: 498.75
2.50 more on weekends
Lets us find unit rate
498.75/35= 14.25
14.25 dollars on weekday add 2.50 and...
16.75 dollars is pay per hour on weekends
16.75*6= 100.5
100.5+498.75=
599.25 dollars
Step-by-step explanation:
Answer:
512.75$
Step-by-step explanation:
2.50 x 6 = 15.00$
So, add 15 to 498.75 by using standard algorithm.
Your result should be 512.75$
Therefore, your answer would be 512.75$

Answers
Answer:
(m+10)(m-9)
Step-by-step explanation:
To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.
Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)
Answer:
[tex](m-9)(m+10)[/tex]
Step-by-step explanation:
When you are given an expression in this format
[tex]ax^2+bx+c[/tex]
You must find two numbers that add up to b while the product is c.
You do trial and error to figure it out for your equation.
[tex]m^2+m-90[/tex]
Hmm... what two numbers add up to 1 and multiplied together equal -90.
Start off with pairs that can equal 90.
45 2
18 5
9 10
Ok, well 45 * 2 does equal 90 but 45 + 2 = 47and 45 + -2 = 43 but there's no way I can make it equal to 1. Next!
18 * 5 equals 90 but 18 + -5 = 13 and 18 + 5 = 23, I can just tell that there's no way I can make this equal to 1.
9 * 10 equals 90, 9 + 10 = 19 but 9 + -10 = -1. Now, that's interesting, We have -1 but we need 1. All we have to do is flip the order. 10 + -9 = 1. And -9 * 10 = -90, PERFECT!
Now use the two numbers and put it in factored form.
