325+1650= 1975
What is the slope of (-9, 8) and (3,- 12)
Answer:
Your slope would be -5/3
Step-by-step explanation:
To find the slope from two points, you would use the formula y2-y1/x2-x1
In this case, the equation would look like -12-8/3-(-9)
-12 - 8 = -20
3 - (-9) = 12
-20/12 = -5/3

Answer:
AE = 30
GD = 5
GF = 10
Step-by-step explanation:
Centroid of medians divide median in the ratio 2 : 1
Therefore,
AG : GE : 2 : 1
Let AG = 2x & GE = x
Since, AG = 20....(given)
Therefore, 2x = 20
x = 20/2
x = 10
GE = x = 10
AE = AG + GE = 20 + 10 = 30
CG : GD : 2 : 1
Let CG = 2x & GD = x
Since, CG = 10....(given)
Therefore, 2x = 10
x = 10/2
x = 5
Since, GD = x
Therefore, GD = 5
BF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10

Answer:
No Soultion
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
distribute
3y + 6 = 5 + 3y
subtract 3y from both sides
6 = 5
no solution since 6 can never equal 5

Solve with cramer's rule x+2y+3z=11, 2x+y+2z=10, 3x+2y+z=9
Answer:
x = 2 , y = 0 , z = 3
Step-by-step explanation:
Cramer's rule is a rule through which we can find the solution of linear equation.
we have the three linear equations as
x+2y+3z=11
2x+y+2z=10
3x+2y+z=9
AX=B
A: coefficient matrix
X= unknown vectors(x,y,z)
D = values of the linear equation (11 , 10 , 9)
now we find the determinant of the given linear equation
determinant of the matrix will be
A = [tex]\left[\begin{array}{ccc}1&2&3\\2&1&2\\3&2&1\end{array}\right][/tex] = 1(1-4) - 2(2-6) + 3(4 - 3)
= 1(-3) - 2(-4) + 3(1)
= -3+8+3 = 8
also D[tex]\neq 0[/tex]
so the determinant is Non zero we can apply Cramer's rule
we will be replacing the first column of the coefficient matrix A with the values of D
by replacing the first column we will get the value of the variable 'x'
Dx = [tex]\left[\begin{array}{ccc}11&2&3\\10&1&2\\9&2&1\end{array}\right][/tex] = 11(1-4) -2(10-18) + 3(20-9) = -33+16+33 = 16
x = [tex]\frac{Dx}{D}[/tex] = [tex]\frac{16}{8}[/tex] = 2
similarly
Dy = [tex]\left[\begin{array}{ccc}1&11&3\\2&10&2\\3&9&1\end{array}\right][/tex] = 1(10-18) -11(2-6) + 3(18 -30) = -8 +44 -36 = 0
y = [tex]\frac{Dy}{D}[/tex] = 0
Dz= [tex]\left[\begin{array}{ccc}1&2&11\\2&1&10\\3&2&9\end{array}\right][/tex] = 1(9 - 20) -2(18 - 30) + 11(4 -3) = -11 +24 +11 = 24
z = [tex]\frac{Dz}{D}[/tex] = [tex]\frac{24}{8} = 3[/tex]
so we have the solution as
x = 2 , y = 0 , z = 3
Therefore the solution for the given linear equations is (2,0,3).
f(x) = 4x + 7
f(8) = 11
I'm not sure exactly what you're trying to ask, but this statement is not true.
to solve a function, you would input a number ,and in this example 8, and replace the x's with 8.
f(8)=4(8)+7
f(8)=32+7
f(8)=39, so when you input 8, your output is 39, not 11.
the function is linear.
Using y=mx+b find the slope for

Answer: for the first one it’s 2 but it says to write as fraction so it’s 10/5
For second it’s 5/6
Step-by-step explanation:
Show your work F(x)=5x^2-4x+1 G(x)=3x-2 H(x)=x+1 K(x)= 4x What is (g*h)(x)= What is g(k(x))= What is k(g(0)) =
Answer:
— What is (g × h)(x)?
The answer is 3x²+x-2
— What is g(k(x))?
The answer is 12x - 2 or 2(6x-1)
— What is k(g(0))
The answer is -8
Explanation:
Given these functions —
[tex]f(x) = 5 {x}^{2} - 4x + 1 \\ g(x) = 3x - 2 \\ h(x) = x + 1 \\ k(x) = 4x[/tex]
Find (g × h)(x)
[tex](g \times h)(x) = g(x) \times h(x)[/tex]
Substitute g(x) = 3x - 2 and h(x) = x + 1
[tex](3x - 2) \times (x + 1) \\ (3x - 2)(x + 1)[/tex]
Multiply the polynomial.
[tex]3 {x}^{2} + 3x - 2x - 2[/tex]
Subtract - 2x out of 3x —
[tex]3 {x}^{2} + x - 2[/tex]
Thus, the answer is —
[tex](g \times h)(x) = 3 {x}^{2} + x - 2[/tex]
Find (g(k(x))
Substitute k(x) = 4x in g(x).
[tex]g(x) = 3x - 2 \\ k(x) = 4x[/tex]
[tex]g(k(x)) = g(4x)[/tex]
[tex]g(4x) = 3(4x) - 2[/tex]
Distribute 3 in 4x —
[tex]g(4x) = 12x - 2[/tex]
Thus the answer is —
[tex]g(k(x)) = 12x - 2[/tex]
Alternative Solution
[tex]g(k(x)) = 2(6x - 1)[/tex]
Find k(g(0))
Given two functions — k(x) and g(x)
[tex]k(x) = 4x \\ g(x) = 3x - 2[/tex]
Evaluate the value of g(0) as we substitute x = 0 in g(x)
[tex]g(0 ) = 3(0) - 2 \\ g(0) = 0 - 2 \\ g(0) = - 2[/tex]
Since we need to find k(g(0)), our currently input is g(0).
From k(x) and g(0) —
[tex]k(x) = 4x \\ g(0) = - 2[/tex]
Substitute g(0) = -2 in k(x)
[tex]k(g(0)) = 4(g(0)) \\ k( - 2) = 4( - 2) \\ k( - 2) = - 8[/tex]
Thus, the answer is —
[tex]k(g(0)) = - 8[/tex]
Plz help me with this equation.
Answer:
y=-1/4x+1
Step-by-step explanation:
The perpendicular equations slope is the negative reciprocal of the other lines, so if I had 2 as a slope, the perpendicular line's slope would be -1/2, I think. Then you just use the found slope and the given point to solve for b, then use the b value you get for the final equation.

Sushil was thinking of a number. Sushil subtracts 3.8 from the number and gets an answer of 53.6. Form an equation with
x
from the information.
Answer:
x = 3.8 + 53.6
Step-by-step explanation:
From the info that they gave you, you can tell that the original number is unknown, so that is x. Since Sushil is subracting 3.8, meaning, to get x, you're going to have to do the opposite which is........addition! So, to get x, you have to add 3.8, and 53.6. I hope I make sense!!

It takes 404040 ink cartridges and 200200200 pages to print a book, and it takes 303030 ink cartridges and 808080 pages to print a magazine. Sarah wants to print books and magazines with at most 300300300 ink cartridges and 120012001200 pages. Let BBB denote the number of books she prints and MMM the number of magazines she prints.
Answer:
40B +30M ≤ 300
200B +80M ≤ 1200
Step-by-step explanation:
The inequality functions are as follows:
For 40 cartridges per book and 30 cartridges per magazine and at most 300 cartridges are used
So the function would be
40B +30M ≤ 300
Now the another would be
There are 200 pages for printing a book and 80 pages are required for printing a magazine also she used at most 1,200 pages
So, the function would be
200B +80M ≤ 1200
