Answer:
The value of function at X=4 is f(4) = 6.
Step-by-step explanation:
Given that:
Function is f(x) = x²-3x+2
A function defines the relationship between an independent variable and a dependent variable.
We have to find the value of function f(4), therefore, we will put x=4 in the given function
f(4) = (4)²-3(4)+2
f(4) = 16-12+2
f(4) = 6
Hence,
The value of function at X=4 is f(4) = 6.

What is the distance (length) of side LM?
Answer:
Distance, d = √((x2 - x1)² + (y2 - y1)²)
L(x1, y1) => L(-3, -1)
M(x2, y2) => M(2, 3)
Distance LM = √((2 - -3)² + (3 - -1)²)
= √((2 + 3)² + (3 + 1)²)
= √((5)² + (4)²)
= √(25 + 16)
= √ 41

If Z is the centroid of triangle TUV, TZ=60, XZ=28, and WZ=25, find each missing measure
The measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.
If Z is the centroid of triangle TUV, then the following are true:
ZV = 2ZX
Given that ZX = 28,
ZV = 2(28)
ZV = 56
Similarly, TZ = 2ZY
60 = 2ZY
ZY = 60/2
ZY = 30
Also, ZU = 2WZ
ZU = 2(25)
ZU = 50
TY = 2ZY
TY = 2(30)
TY = 60
XV = XZ + ZY
XV = 28 + 50
XV = 78
Therefore the measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.

Answer:
Lets mark the unmarked angle as angle A and the base of the building as BC
We can use tan to find this
tan=opposite/adjacent
by knowing the 2 interior angles we can calculate the measure of A sicne the interior angles of any triangle add up to 180
52+90+A=180
142+a=180
38=a
tan(38)=BC/300
300 tan(38)=bc
using a calculator we see that bc=234.385689 or 234meters rounded

The y-value is
The solution is
Step-by-step explanation:
The given equations are :
y = x + 3 .....(1)
y = 2x – 5 ......(2)
The table for equation (1) is :
x = 0, 1, 2, 8
y = 3, 4, 5, 11
The table for equation (2) is :
x = 0, 1 , 2, 8
y = -5, -3, -1, 11
From the graph we can see that,
The x-value is = 8
The y-value = 11
The solution is = (8,11).
The x-value is = 8, the y-value = 11 and the solution is = (8,11)
How to determine the equation solutions?The equations are given as:
y = x + 3
y = 2x - 5
Next, we plot the graph of the equations
From the graph of the equations, we have:
(x,y) = (8, 11)
Hence, the x-value is = 8 and the y-value = 11
So, the solution is = (8,11)

the equation is -2x² = 4-3 (x + 1) and the question is justify that it is a 2nd degree equation with the unknown x complete.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
-2x² = 4-3 (x + 1)
-2x² = 4-3x-3
-2x² = -3x -7
0 = 2x² -3x -7
We know that the degree of the equation is the highest power of x variable in the given equation.
In the equation 0 = 2x² -3x -7 the highest power of x variable in the given equation is 2.
Thus, the degree of the equation is 2.
Also in the equation 0 = 2x² -3x -7, the unknown variable is 'x'.
Let us determine the value 'x'
2x² -3x -7 = 0
Add 7 to both sides
[tex]2x^2-3x-7+7=0+7[/tex]
[tex]2x^2-3x=7[/tex]
Divide both sides by 2
[tex]\frac{2x^2-3x}{2}=\frac{7}{2}[/tex]
[tex]x^2-\frac{3x}{2}=\frac{7}{2}[/tex]
Add (-3/4)² to both sides
[tex]x^2-\frac{3x}{2}+\left(-\frac{3}{4}\right)^2=\frac{7}{2}+\left(-\frac{3}{4}\right)^2[/tex]
[tex]x^2-\frac{3x}{2}+\left(-\frac{3}{4}\right)^2=\frac{65}{16}[/tex]
[tex]\left(x-\frac{3}{4}\right)^2=\frac{65}{16}[/tex]
[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]
solving
[tex]x-\frac{3}{4}=\sqrt{\frac{65}{16}}[/tex]
[tex]x-\frac{3}{4}=\frac{\sqrt{65}}{\sqrt{16}}[/tex]
[tex]x-\frac{3}{4}=\frac{\sqrt{65}}{4}[/tex]
Add 3/4 to both sides
[tex]x-\frac{3}{4}+\frac{3}{4}=\frac{\sqrt{65}}{4}+\frac{3}{4}[/tex]
[tex]x=\frac{\sqrt{65}+3}{4}[/tex]
similarly solving
[tex]x-\frac{3}{4}=-\sqrt{\frac{65}{16}}[/tex]
[tex]x=\frac{-\sqrt{65}+3}{4}[/tex]
So the solution of the equation will have the values of x such as:
[tex]x=\frac{\sqrt{65}+3}{4},\:x=\frac{-\sqrt{65}+3}{4}[/tex]

PLS ANSWER 64 POINTS (64 POINTS AND ILL MARK BRAINIEST) PLS...
Answer:
A
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
So the formula for slope is y = mx + b
Here is what it looks like so far: y = -5x + 3
In that equation, -5 is m (slope)
and 3 is b (y-intercept)

Given that f ( x ) = 3 x − 2 and g ( x ) = 2 x , evaluate f ( g ( − 1 ) )
g(x) = 2x
9(-1) = -2
f(x) = 3x-2
f(g(-1)) = f(-2) = 3*(-2) - 2 = -8
Answer:
-8
Step-by-step explanation:
g(-1)= 2 * -1 = -2
So f(g(-1)) will be f(-2)
F(-2) = (3 * -2) - 2
