Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?
Answer:
5.25 feets
Step-by-step explanation:
Given the question :
Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?
Length of one side of Square poster = 1 1/2 Feets = 3/2 feets
Length of wall = 12 feets long
Since Abdul wants the poster to be centered in the wall; then the picture should be placed such that there must be equal space left on either side of the wall after hanging.
Hence, (12/2 - 1 1/2) = (6 - 0.75) feets
= 5.25 feets

A.y=(x-2)(x-1)
B.y=-(x-2) (x+1)
c y= -( x+2) ( x*1)
D. y= ( x-2) (x+1)
Answer:
B. v = - (x - 2)(x + 1)Step-by-step explanation:
The parabola opens downward so a<0
zeros are: x₁=-1 and x₂=2, so the factors are:
(x - x₁) = [x - (-1)] = (x + 1)
(x - x₂) = (x - 2)
which gives: - (x + 1)(x - 2)

find the area of the figure
Answer:
90 inches squared
Step-by-step explanation:
To do this you would first find the area of the 2 triangles shown on the side so we would do 5 times 2 divided by 2 since that is how we solve this problem so we would get 5 inches squared for the 2 triangles then we would find the area of the square which is 100 since it is a 10 by 10 then you would subtract 5+5 by 100 which is 90 so 90 inches squared would be the answer
Answer:
Your correct answer is 90 sq. in.
Step-by-step explanation:
Find the area of the 2 triangles that are shown on the side.
5 x 2 divided by 2 = 5 sq. in.
Now, find the area of the square
The answer for this is 100 because it is a 10 x 10
Next, subtract
5 + 5 by 100 = 90

8. Find the equation of a line in slope intercept form that is parallel to the line y = -2x - 3 that goes
through the point (2, 1).
Work:
Answer:
Step-by-step explanation:
Hey there!!
To solve this type of question, use these steps.
Find these 1st equation by using one point formula of point.After this from equation 2 find slope, by comparing it with y= mx + c if it is in slope intercept form. Then, as per the conditions of parallel lines, use m1=m2, then put the value of m1 in equation 1st.Then simplify them.So, let's work with these steps.
Now,
The equation of a st.line passing through point (2,1) is,
[tex](y - y1) = m1(x - x1)[/tex]
Put all values.
[tex](y - 1) = m1(x - 2)[/tex]
It is the 1st equation.
Another equation is,
y = -2x -3.......(ii)
Comparing the equation with y = mx+c.
Therefore, from equation (ii)
m2 = -2
Now, as per condition of parallel lines,
m1=m2= -2
Putting the value of m1 in equation 1st.
[tex](y - 1) = - 2(x - 2)[/tex]
y - 1 = -2x + 4
y = -2x +5.
Therefore, the equation is y = -2x +5.

First, add 4x to both sides:
10 - 4x (+4x) = -9x (+4x)
10 = -9x + 4x
10 = -5x
Isolate the variable, x. Divide -5 from both sides:
-5x = 10
(-5x)/-5 = (10)/-5
x = 10/-5
x = -2

y=3x+12 positive or negative
Answer:
x = -4 thus negative
Step-by-step explanation:
Solve for x:
3 x + 12 = 0
Hint: | Isolate terms with x to the left hand side.
Subtract 12 from both sides:
3 x + (12 - 12) = -12
Hint: | Look for the difference of two identical terms.
12 - 12 = 0:
3 x = -12
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 3 x = -12 by 3:
(3 x)/3 = (-12)/3
Hint: | Any nonzero number divided by itself is one.
3/3 = 1:
x = (-12)/3
Hint: | In (-12)/3, divide 12 in the numerator by 3 in the denominator.
12/3 = (3×4)/3 = 4:
Answer: x = -4

let a and b be positive integers. 23^a x 23^b
Answer:
23 ^ ( a+b)
Step-by-step explanation:
23^a *23^b
Since the bases are the same, we can add the exponents
23 ^ ( a+b)
Answer:
23^(a+b)
Step-by-step explanation:
A^x*A^y = A^(x+y)
you can think of it like this
A^x = A*A*A*.......*A x times
A^y = A*A*A*....*A y times
therefore A^x * A^y = A*A*A*...*A (x+y) times
=A^(x+y),
so in our case A = 23, and x and y were a and b, so 23^a * 23^b = 23^(a+b)
Which relation is also a function?
Answer:
Step-by-step explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. For example, consider the following sets X and Y.
When we say about relation is a function
The given table relation is not a function
the graph relation is not a function
Given :
A relation is a function when all x values has exactly only one y value .
Each input has only one output for a function .
When x values are repeated then we can say that there is two output .
So that is not a function .
In the given table, we have x=5 repeated twice .
when x=5 there are two outputs [tex]-3 and -2[/tex]
for x=5, there are two outputs.
The given table relation is not a function
Now we consider the graph
When x=2 , there are 2 y values [tex]-3 \; and \; -4[/tex]
So input 2 has two output values
Hence , the graph relation is not a function

A ship must be unloaded by two cranes in 12 hours. Both cranes worked for 8 hours and then one of them broke. The rest of the work was done by the other crane in 7 hours. How long would each crane take to do the entire job if it was working alone? Thank you!
Answer:
6 hours
Step-by-step explanation:
8 hours x 2 cranes = 16 hours of total work
After one broke
7 hours x 1 crane = 7 hours of total work
16 + 7 = 23 hours
It would take 23 hours for one crane to do the whole job.
