Can someone help me with this I'm confused
Answer:
bro sorry I can't helpStep-by-step explanation:
follow me mark as brainleastplease help! Complete the function for this graph.
Answer:
y = - 2|x - (-2)| + 1
Step-by-step explanation:
The general form of an absolute value function is y = a|x – h| + k, where a ≠ 0.
The value of a determines whether the graph opens up or down. If a is negative, the graph opens down. This holds true, as the value of a = -2
The given graph for the absolute function has a vertex (h, k) of (-2, 1). This is the maximum point of the graph.
Therefore, the missing values on the given equation is the value of the vertex. It has to be written as y = - 2|x - (-2)| + 1 because the equation on your given problem is formatted according to the general form of the absolute value function, y = a|x – h| + k.

Use the Pythagorean theorem to find x, in simplest radical form
Answer:
[tex]4\sqrt{21}[/tex]
Step-by-step explanation:
Pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].
Which in this case:
'c' is hypotenuse. (hypotenuse = 20)
'a' and 'b' are the other sides. (a = x, b = 8)
[tex]a^{2} +b^{2}= c^{2}[/tex] [tex]x^{2} +8^{2} =20^{2}[/tex] [tex]x^{2} + 64 = 400[/tex] [tex]x^{2} = 336[/tex]Now we should just take square root from the both sides.
and the answer will be [tex]\sqrt{336}[/tex] or [tex]-\sqrt{336}[/tex], but a side of a triangle can not be a negative number! so the answer will be [tex]\sqrt{336}[/tex].
As you see [tex]\sqrt{336}[/tex] is not the simplest radical.
We can write [tex]\sqrt{336}[/tex] as [tex]\sqrt{16 * 21}[/tex].
And from the laws of radical we can write [tex]\sqrt{16*21}[/tex] as [tex]\sqrt{16} * \sqrt{21}[/tex].
[tex]\sqrt{16} * \sqrt{21} = \sqrt{16}\sqrt{21} = 4\sqrt{21}[/tex]

Answer:
140+x+x = 180°(co-interior angle)
140+2x=180°
2x=180°-140°
2x = 40°
x = 40°/2
x = 20°
check:
140+20+20 = 180
180=180

Answer:
-3x^2-10x+6
Step-by-step explanation:
the first mistake would be writing the 4x^2 as positive when it's supposed to be negative. the 1 is also supposed to be positive. correct difference would be:
(x^2-10x+5)-(4x^2-1)
=(x^2-4x^2)-10x+5+1
=-3x^2-10x+6
Answer:
Mistake in step 2
Step-by-step explanation:
(x^2-10x+5)-(4x^2-1)
x^2-10x+5-4x^2+1
-3x^2-10x+6
-(3 x^2 + 10 x - 6)
There is a mistake in step 2 in the picture,
-(4x^2-1)

1. Please Determine the equation of the line from the tables and the graphs.
1. find equation of line with given data :
b) from the given table, we get y - intercept (c) = -4
now let's find slope (m) :
[tex] \dfrac{y_2-y_1}{ x_2 - x_1}[/tex][tex] \dfrac{0 - ( - 2)}{10 - 5} [/tex][tex] \dfrac{2}{5} [/tex]so, the required equation will be :
[tex]y = \dfrac{2}{5} x - 4[/tex]c) from the given graph we can see that y - intercept (c) = 3
now, let's find the slope (m) :
[tex] \dfrac{3 - 0}{0 - 7} [/tex][tex] - \dfrac{3}{7} [/tex]the equation will be :
[tex]y = - \dfrac{3}{7} x + 3[/tex]d) From this graph we get y - intercept (c) = -4
slope :
[tex] \dfrac{4 - 0}{4 - 2} [/tex][tex] \dfrac{4}{2} [/tex][tex]2[/tex]so, required equation will be :
