Choose the polynomial that is written in standard form 7x^5+8x^8+27x
Don’t need the answer just couldn’t find the question lol so the answer is 3
Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3
Step-by-step explanation:
In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.
Then the correct option is d.
Where the degree of the first term is (4 + 1) = 5
The degree of the second term is (2 + 2) = 4
The degree of the third therm is 3.
We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:
-3*x^4*y + 2*x^2*y^2 + 5*y^3

Step-by-step explanation:
X^2+9x+7=y standard to vertex form
Answer:
y = (x + 4.5)² - 13.25
Step-by-step explanation:
y = x² + 9x + 7
We need to get a perfectly squared binomial as part of the right side.
Take the '9x' term, divide it in half, square it, add and also subtract it on the right side, as shown below. That would be (4.5)² = 20.25 added and subtracted.
y = x² + 9x + 7
y = x² + 9x + 20.25 + 7 - 20.25
y = (x² + 9x + 20.25) - 13.25
y = (x + 4.5)² - 13.25
y = (x + 4.5)² - 13.25
Vertex Form is y = a(x-h)² + k, where the parabola vertex is (h, k)
So if you wrote this as y = 1(x - [-4.5] )² + (-13.25), we would see that a = 1, and h = -4.5 and k = -13.25.
Vertex = (-4.5, -13.25)
I verified on a graphing calculator that this is indeed the vertex of the parabola.

What is the linear relationship?A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.
The rule is given in the question, as follows:
y is 3 less than x
For each value of x in the first column, the corresponding value of y in the second column can be calculated by subtracting 3 from x.
For example, if x is 10, then y is 3 less than x, which is 7 (10 - 3 = 7).
Similarly, if x is 8, then y is 5 (8 - 3 = 5), and if x is 6, then y is 3 (6 - 3 = 3).
The table for the given rule can be completed as follows:
X Y

x = 11
Hey there!
x + 8 = 19
SUBTRACT 8 to BOTH SIDES
x + 8 - 8 = 19 - 8
CANCEL out: 8 - 8 because it give you 0
KEEP: 19 - 8 because it give you the x-value
NEW EQUATION: x = 19 - 8

Answer: Yes, they are mutually exclusive. You cannot have 2+ heads and 0 heads at the same time. They are not independent. The result of 2+ heads nullifies the chance that 0 heads are flipped!

Answer:
linear: blue graph, Table 2, 2x-3y=7, y=-4
nonlinear: red graph, Table 1, Table 3, y=2x^2+4, y=3/x+2
Step-by-step explanation:
It is hard to check answers when you don't know the question. Apparently, there are additional features of the question that are not shown.
__
The equation of the red graph is y=(x+5)³. (nonlinear)
The equation of the blue graph is y=2x-6. (linear)
The equation of Table 1 is y=x². (nonlinear)
The equation of Table 2 is y=2x+4. (linear)
The equation of Table 3 is y=|x|. (nonlinear)
__
You have correctly classified the equations we see. We can't tell if there are more that we don't see.
_____
The tables all have sequential values of x, so the way to tell linear/non-linear is by looking at first differences in the y-values:
Table 1: 4-1 = 3; 9-4 = 5 . . . . different, so non-linear
Table 2: 8-6 =2; 10-8 = 2; others are also 2 . . . . all the same, so linear
Table 3: 1-2 = -1, 0-1 = -1, 1-0 = 1 . . . . different, so non-linear

Find the quotient and remainder 975 divided by 17
Answer:
975 / 17 = 57 R 6
Step-by-step explanation:
To get a good starting point, let's round these values to "nicer" numbers. 975 is close to 1000, and 17 is close to 20, and 1000 / 20 = 50, so let's start by looking at 17 x 50 and go from there.
There are a few ways to calculate 17 x 50, but here I'm gonna go off what we already know: 20 x 50 = 1000, and 20 - 3 = 17, so 17 x 50 = 20 x 50 - 3 x 50, or 1000 - 150, which is 850. How many more 17s can we fit from 850 to 975? Well, the difference between the two numbers is 125, so finding the quotient of 125 and 17 should be enough: 17 fits into 125 7 times, with 6 remaining.
Altogether then, 975 / 17 has a quotient of 50 + 7 = 57, and a remainder of 6.
