Which point is a point where the graph of y= (x + 2)(x2 + 4x+3) crosses the x-axis?
Answer:
A. (-3,0)
Step-by-step explanation: you have to set the equation y to zero and than calculate the x
--> (x + 2)(x2 + 4x+3) = 0
--> (x+2) = 0 and (x2 +4x + 3) =0
--> X = -2 and D= (4² - 4*2*3) = 4
X = (-4 + [tex]\sqrt{4}[/tex]) / 2 of X = (-4 + [tex]\sqrt{4}[/tex]) / 2
x= -1 x=-3
Answer:
The answer is (-3,0)

Answer: im actually doing this rn
Answer:
I know im late but here is the answer can i still get breainliest?
Step-by-step explanation:
a) Your business partner describes this as a high positive correlation. Is your partner correct? Why or why not?
Yes, my partner is correct because as the fat increases the calories increase. And when the points are rising from the left to the right, this indicates a positive correlation.
b) Using the drawing tools, draw a trend line (line of best fit) on the graph above.
it's basically a line that goes up to the right like this /
c) Judge the closeness of your trend line to the data points. Do you notice a relationship between the data points?
This is a linear trend because it moves in a line going up at a predictable rate.
d) Is the trend line linear? If so, write a linear equation that represents the trend line. Show your work.
No, the trend line is not linear, because it squiggles at the end.

What is the sum of 1/8 and (-3/16)
Answer:
D, or [tex]\frac{-1}{16}[/tex]
Step-by-step explanation:
To add (or subtract) fractions, you need to have a common denominator.
You might notice that the 16 on the bottom is a multiple of 8.
8*2 as a matter of fact
If we multiply [tex]\frac{1}{8\\}[/tex] by 1, it doesn't do anything, it stays as 1/8
1 is the same thing as [tex]\frac{1}{1}[/tex] and is also the same as [tex]\frac{2}{2}[/tex]
If we multiply [tex]\frac{1}{8}[/tex] by [tex]\frac{2}{2}[/tex], we get a bigger fraction, which is [tex]\frac{2}{16}[/tex]
So, our problem can be re-written as [tex]\frac{2}{16}+(-\frac{3}{16} )[/tex]
To add (or subtract) fractions with common denominators, you keep the common denominator and add (or subtract) the numerator.
[tex]\frac{2}{16}+(-\frac{3}{16})=\frac{2-3}{16}=\frac{-1}{16}[/tex]
The last step is to see if our answer can be reduced.
A fraction can't be reduced if there is a prime number in either the numerator or the denominator.
There is a -1 in the numerator, which is prime, and therefore, the fraction can't be reduced.

The base of a triangle is nine centimeters longer than the perpendicular height. If the area of the triangle is 180 square centimeters, what is the length of the base, in centimeters?
Answer:
The base is 24 cm long.
Step-by-step explanation:
Equations
Let's call
b= base of the triangle
h=height of the triangle
The base is 9 cm longer than the height, thus:
b = h + 9
The area of the triangle is:
[tex]\displaystyle A=\frac{bh}{2}[/tex]
[tex]\displaystyle A=\frac{(h+9)h}{2}[/tex]
And its value is 180:
[tex]\displaystyle \frac{(h+9)h}{2}=180[/tex]
Multiplying by 2:
[tex](h+9)h=360[/tex]
Operating:
[tex]h^2+9h-360=0[/tex]
Factoring:
[tex](h-15)(h+24)=0[/tex]
The only valid positive solution is:
h = 15 cm
And b = h + 9 = 24
b = 24 cm
The base is 24 cm long.

Answer: -15
Step-by-step explanation:
The average rate of change for the interval from x = 7 to x = 8 is -15. The correct option is B.
What is quadratic function?A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.
Since the quadratic function has a vertex at (0,3), the equation for the function can be written in vertex form as:
y = a(x - 0)^2 + 3
Where "a" is a constant that determines the shape of the parabola. To find the value of "a", we can use one of the other points on the parabola. Let's use the point (1, 2):
2 = a(1 - 0)^2 + 3
Simplifying this equation, we get:
a = -1
So the equation for the quadratic function is:
y = -x^2 + 3
Now we can use this equation to find the average rate of change between x = 7 and x = 8. The value of the function at x = 7 is:
y = -7^2 + 3 = -46
The value of the function at x = 8 is:
y = -8^2 + 3 = -61
The average rate of change between x = 7 and x = 8 is:
(y2 - y1) / (x2 - x1) = (-61 - (-46)) / (8 - 7) = -15
Therefore, the average rate of change for the interval from x = 7 to x = 8 is -15.
