Given
[tex]-3x - 9[/tex]
Required
Factorize
The options are not given; So, I'll answer on a general term
[tex]-3x - 9[/tex]
Express -9 as -3 * 3
[tex]-3x - 9 = -3x - 3 * 3[/tex]
Then factorize 3 out of the expression as:
[tex]-3x - 9 = 3(-x - 3)[/tex]
Another way is to factor -3 out of the expression as:
[tex]-3x - 9 = -3x - 3 * 3[/tex]
[tex]-3x - 9 = -3(x + 3)[/tex]

Ifa rectangle measures 20 meters by 48 meters, what is
the length, in meters, of the diagonal of the rectangle?
Answer:
[tex]52m[/tex]
Step-by-step explanation:
We can use the Pythagorean theorem to find the length of the diagonal since drawing a diagonal across a rectangle results in two right angle triangles.
Length of diagonal [tex]= \sqrt{20^2+48^2}[/tex] (The length of the diagonal can be thought of as the hypotenuse of one of the right angle triangles)
[tex]=\sqrt{2704}[/tex]
[tex]=52 m[/tex]
∴ The length of the diagonal is [tex]52 m[/tex]

Which function represents g(x), a reflection of f(x) = On a coordinate plane, 2 exponential functions are shown. g (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1. It goes through (negative 1, 1) and crosses the y - axis at (0, 0.5).(3)x across the y-axis?
g(x) = 2(3)x
g(x) = −One-half(3)x
g(x) = One-half(3)−x
g(x) = 2(3)−x
Answer: C. g(x) = 1/2(3)^-x

The reflection of the given function [tex]f(x)=\frac{1}{2}(3)^x[/tex] over the y-axis [tex]g(x)=\frac{1}{2}(3)^{-x}[/tex]
What is a function?"It defines a relation between input and output values.""In function, for each input there is exactly one output."What is reflection?"It is a mirror image of the shape or graph of a function. "
For given question,
We have been given a function [tex]f(x)=\frac{1}{2}(3)^x[/tex]
We know that
A reflection over the y-axis interchanges positive x-values with negative x-values, swapping x and -x.
The reflection of the given function over the y-axis will be equal to
(Remember interchanges positive x-values with negative x-values)
[tex]g(x)=\frac{1}{2}(3)^{-x}[/tex]
Therefore, the reflection of the given function [tex]f(x)=\frac{1}{2}(3)^x[/tex] over the y-axis [tex]g(x)=\frac{1}{2}(3)^{-x}[/tex]

It rained nine days in the month of April. Based on this, what is the probability that it does not rain on the first day of May? *
Answer: 0.7
Step-by-step explanation:
April has 30 days, and we know that it rained in 9 of them.
Then the probability that there will be rain in a random day, can be estimated as the quotient between the number of days where was rain and the total number of days, this probability will be:
P = 9/30 = 0.3
And we can extrapolate this probability to May.
Then we can estimate that the first day of May, the probability of rain will be around 0.3
Then the probability that it does not rain in the first day of may will be:
1 - 0.3 = 0.7

I think of a number, multiply it by three, and add four. I get twenty two.
a) Using the statement above, form an equation.
Use the letter 'x' for the unknown number.
3x+4=22
b)
Solve the equation.
Step-by-step explanation:
3x+4=22
3x=22-4
3x=18
x=18/3
x=6
Answer:
the answer should be like 3×6+4=22
Step-by-step explanation:
im not sure with A I mean, forming an equation, I guess it should be 3x+4=22 that's all as texted and for B
what I did was subtract 4 from 22 which I got 18 and then I divided 18 with 3, since the question said it was multiplied by 3.
22-4=18.
18÷3=6. 6×3=18
3×6+4=22

Twice the sum of 13 and x is not greater than 15
Answer:
x = 0
Step-by-step explanation:
This is saying that 2(13x) < 15
If you have 2[13(0)] < 15
It will come to 2(0) < 15
This equals 0 < 15 which is true therefore making the x value = 0
line s has a slope of 7/4. Line t is perpendicular to s. What is the slope of line t?
Answer:
Step-by-step explanation:
The formula governing this situation is
m1 * m2 = - 1
Method One
So let m1 = 7/4
(7/4)*m2 = - 1 Multiply by 4
7*m2 = -1*4 Divide by 7
m2 = -4/7
Method Two
Most people teaching this try to get you to use reciprocals. If you know how to do that then the answer is much simpler.
7/4 m2 = -1 Multiply by 4/7
4/7 * 7/4*m2 = - 1 * 4/7
m2 = -4/7
However if you are not comfortable with reciprocals, then then the thing to do is to handle them the way I showed you in the first method.

Simplify the midpoint of PR.
Q (2b, 2c)
R (2a+2b, 2c)
Pl(0,0)
S (2a, 0)
Answer:
The midpoint of PR is;
(a + b, c)
Step-by-step explanation:
Here, we want to get the coordinates of the midpoint of PR
To get these, we make use of the midpoint formula
Mathematically, that will be;
(x,y) = (x1+y1)/2, (x2+y2)/2
(x1,y1) = (0,0)
(x2,y2) = (2a+2b, 2c)
The midpoint is thus;
(2a+2b)/2 , 2c/2
= (a + b, c )
Answer:
(a+b, c)

In the parallelogram below, x=
Answer:
23°
Step-by-step explanation:
By interior angle sum postulate of a triangle.
x = 180° - ( 124° + 33°)
x = 180° - 157°
x = 23°
The value of x is 23°
What is the angle sum property of a triangle?
The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°
Given here, in the given triangle separated by the diagonal in the parallelogram two angles are 33° and 124°
therefore by angle sum property, the value of the third angle is
is x=180°-(33°+124°)
x= 23°
Hence, the value for x is 23°
