Answer:
x = 3 and x = 3
Step-by-step explanation:
The given equation is
2x² - 12x + 18 = 0
Divide both sides by 2:
x² - 6x + 9 = 0
We need two numbers that will add up to -6 and their product is 9.
The two numbers are -3 and -3.
=> x² - 3x - 3x + 9 = 0
x(x - 3) - 3(x - 3) = 0
(x - 3)(x - 3) = 0
x = 3 and x = 3

Answer:
f(q) = 11/3q+2/3
Step-by-step explanation:
11q - 4 = 3r - 6
Solve for r
Add 6 to each side
11q - 4+6 = 3r - 6+6
11q +2 = 3r
Divide each side by 3
11q/3 + 2/3 = 3r/3
11/3q + 2/3 = r
f(q) = 11/3q+2/3

Answer:
g(x) = - sqrt(x+8) reflected about the x axis and shifted 8 units to the left
h(x) = 2 sqrt(x) +1 is stretched by 2 in the y direction and shifted up 1 in the y direction
Step-by-step explanation:
y = f(x + C) C > 0 moves it left
So we moved it 8 units to the left
y = −f(x) Reflects it about x-axis
g(x) = - sqrt(x+8) reflected about the x axis and shifted 8 units to the left
y = f(x) + C C > 0 moves it up
so we moved it up 1 units
y = Cf(x) C > 1 stretches it in the y-direction
and stretched it by 2 in the y direction
h(x) = 2 sqrt(x) +1 is stretched by 2 in the y direction and shifted up 1 in the y direction
Answer:
g(x) = - square root (x+8) reflected about the x axis and shifted 8 units to the left
h(x) = 2 square root x) +1 is enlarged by 2 in the y direction and shifted up 1 in the y direction

A direct variation function contains the points (-9, -3) and (-12, -4). Which equation represents the function?
y = -3x
y=-
o ya
y = 3x
Answer:
[tex]y=\frac{1}{3} x[/tex]
Step-by-step explanation:
we need a function that when we plug the value of x, we get the given value of y.
In the coordinate point
(-9, -3)
the x and y values are:
x = -9
y = -3
so we can see that the value of y is one third of the x value (because -9/3 = -3):
[tex]y=\frac{1}{3} x[/tex]
this is also true for the secod point:
(-12, -4)
here the x and y values are:
x = -12
y = -4
again the y value is one third of the x value (because -12/3 = -4):
[tex]y=\frac{1}{3} x[/tex] ⇒ this is the equation that represents the function.

Step-by-step explanation:
(log 0.04 − 2 log 0.3) / (1 − log 15)
Change 1 to log 10.
(log 0.04 − 2 log 0.3) / (log 10 − log 15)
Use log property: a log b = log bᵃ.
(log 0.04 − log 0.09) / (log 10 − log 15)
Use log property: log a − log b = log (a/b).
log (0.04/0.09) / log (10/15)
Reduce fractions.
log (4/9) / log (2/3)
Change 4/9 to (2/3)².
log ((2/3)²) / log (2/3)
Use log property: log bᵃ = a log b.
2 log (2/3) / log (2/3)
Divide.

The coordinates for point M is (12, 6)
what is section formula?Section formula is used to find the coordinates of a point that splits a line segment internally or externally into a ratio of m:n.
(x, y) = ( mx2 + nx1/ m+n, my2 + ny1/ m+n)
Given:
Coordinates of A(0, 15) and B (20, 0)
ratio is 3:2
Now,
x1=0, x2= 20, y1= 15, y2=0
let the coordinates of M is (c, d)
Using section formula
c=2*0+3*20/5
c=12
and d= 15*2+ 2*0/5
d= 6
Hence, the coordinates of M are (12, 6).

Answer:
Tamara needs to cover a total of 476 square feet.Tamara will have enough material to cover all four walls.Step-by-step explanation:
If the room dimensions are 8 1/3 feet by 11 1/2 feet, the perimeter length is ...
P = 2(L+W) = 2(8 1/3 +11 1/2) = 2(19 5/6) = 39 2/3 feet
The area of the walls is the product of this perimeter length and the height of the wall. If that height is 12 feet, then the wall area is ...
A = PH = (39 2/3 ft)(12 ft) = 476 ft²
Tamara needs to cover a total of 476 square feet.

Use emlimination to solve the system x-5y=20 and x+3y=-4 for x
Answer:
y=-3 , x=5
Step-by-step explanation:
x-5y=20 x-5y=20-(x+3y=-4) new -x-3y=4
x-5y=20
-8y=24
-8 -8
y=-3 x-5y=20
x-5(-3)=20
x+15=20
-15= -15
x=5
The value of x is 5 for the system of equations [tex]x-5y=20[/tex] and[tex]x+3y=-4[/tex].
The given system of equations are :
[tex]x-5y=20[/tex] ...(1)
[tex]x+3y=-4[/tex]...(2)
To solve the equation, multiply equation (2) with -1.
[tex]-x-3y=4[/tex]...(3)
Add equation (1) and (3):
[tex]x-5y-x-3y=20+4[/tex]
Combine like terms:
[tex]-8y=24[/tex]
Divide both sides by -8:
[tex]y=-3[/tex]
Now, we substitute the value of [tex]y = -3[/tex] into either of the original equations to solve for x.
[tex]x - 5(-3) = 20[/tex]
[tex]x + 15 = 20[/tex]
[tex]x = 20 - 15[/tex]
[tex]x = 5[/tex]
Therefore, the solution to the system of equations is[tex]x = 5[/tex] and [tex]y = -3.[/tex]

What is the length of AC?
Round to one decimal place.
Answer:
x = 5.7
Step-by-step explanation:
Use the Triangle-Angle-Bisector Theorem.
[tex]\frac{CD}{DB}[/tex] = [tex]\frac{AC}{AB}[/tex]
Substitute the corresponding side lengths.
[tex]\frac{2}{2.8}[/tex] = [tex]\frac{x}{8.1}[/tex]
Cross Multiply.
16.2 = 2.8x
Divide each side by 2.8.
[tex]\frac{16.2}{2.8}[/tex] = [tex]\frac{2.8x}{2.8}[/tex]
Since 2.8 cancels out 2.8x, your left with x.
Then divide 16.2 by 2.8.
x = 5.7

if triangle ABC = triangle EDF where the coordinates of A(-1, 1), B(2,4), and C(3,1), what is the
measure of EF?
Answer:
The measure of EF is 4 units
Step-by-step explanation:
If triangle ABC = triangle EDF where the coordinates of A(-1, 1), B(2,4), and C(3,1), what is the measure of EF?
To find the measure of EF, we will follow the steps below;
since triangle ABC = triangle EDF the coordinates of triangle ABC are A(-1, 1), B(2,4), and C(3,1), then the coordinates of triangle EDF are E(-1, 1), D(2,4), and F(3,1)
To find the measure of EF, we will use the distance formula;
|EF| = √(x₂-x₁)² + (y₂-y₁)²
E(-1, 1) F(3,1)
x₁=-1
y₁=1
x₂ =3
y₂ = 1
We can now proceed to substitute the values into the formula;
|EF| = √(3+ 1)² + (1-1)²
= √(4)² + (0)²
= √(4)²
=√16
=4
The measure of EF is 4 units

Answer:
x = 3
Step-by-step explanation:
The area of a rectangle is length*width, while for a rectangle it is the length*width over two. Now lets substitute the values given.
3(x+12) = 3x+36 = Area of rectangle
5(2x)/2 = 10x/2 = 5x = Area of triangle
We know that the area of the rectangle is 3 times the area of the triangle, so 3x + 36 = 3(5x) --> 3x+36 = 15x
This gives basic linear equation of 3x + 36 = 15x to solve. Isolate x and solve:
36 = 12x

Write an inequality to represent the model and solve for the unknown number
let

twice a number = 2 × x
= 2x
Three more than twice a number = 2x + 3
Three more than twice a number is greater than negative fifteen:
2x + 3 > -15
