If AD = 12 and AC = 4y-36, find the value of y
Answer:
y=12
Step-by-step explanation:
in that case, then 12 = 4y -36
12 =4y -36
12+36=4y
48=4y
48/4=y
12=y
answer :y=12
Answer:
y = 15
Step-by-step explanation:
Consider that the attached screenshot is the figure given in the problem. Also consider that DC = 12, due to the fact that AD = 12, and there is a midpoint at point D.
AD + DC = AC
12 + 12 = 4y - 36
24 = 4y - 36
+ 36 + 36
60 = 4y
60/4 = 4y/4
y = 15

Which statement is true?
Answer:
Step-by-step explanatmkjion:
The Correct statements is [tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex].
To determine which statement is true, let's evaluate each statement one by one:
[tex]\sqrt[m]{x} * \sqrt[m]{y} = 2\sqrt[m]{xy}[/tex]
This statement is false. The correct product of two nth roots ([tex]\sqrt[m]{x}[/tex] and [tex]\sqrt[m]{y}[/tex]) is [tex]\sqrt[m]{x*y}[/tex], not 2[tex]\sqrt[m]{x*y}[/tex].
[tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex].
This statement is true. When raising an nth root to a power, you can simply multiply the exponents. So, [tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex]..
[tex]a \sqrt[n]{x}+ b \sqrt[n]{x} = ab \sqrt[n]{x}[/tex]
This statement is false. The correct result of adding two nth roots is not the product of the coefficients. It's simply (a + b) [tex]\sqrt[n]{x}[/tex].
[tex]\sqrt[m]{x} /\sqrt[m]{y} = \sqrt[m]{xy}[/tex]
This statement is false. The correct division of two nth roots ([tex]\sqrt[m]{x}[/tex] divided by [tex]\sqrt[m]{y}[/tex]) is not equal to the product of the roots. The correct division is:
[tex]\sqrt[m]{x} /\sqrt[m]{y} = \sqrt[m]{x/y}[/tex]
So, [tex]\sqrt[m]{x} /\sqrt[m]{y}[/tex] is equal to [tex]\sqrt[m]{x/y}[/tex], not [tex]\sqrt[m]{xy}[/tex].
Correct statements:
[tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex]

Solve the system of equations -x+y=15−x+y=15 and -5x-3y=27−5x−3y=27 by combining the equations
Answer:
Solution: x= -36, y=51
Step-by-step explanation:
Solve the system:
x + y = 15
-5x - 3y = 27
By using the reduction method.
Multiply the first equation by 3:
3x + 3y = 45
Add it to the second equation:
3x - 5x = 45 + 27
Simplifying:
-2x = 72
Dividing by -2:
x = 72/(-2)
x = -36
From the first equation:
-36 + y = 15
Adding 36:
y = 15 + 36 = 51
y = 51
Solution: x= -36, y=51

Study this incomplete image of a geometric construction. This image may result from the construction of ____
A. a line parallel to line AB through C.
B. a perpendicular to line AB.
The next step in this construction is to set the compass width to
A. line segment DC and draw an arc centered at D intersecting the second arc.
B. line segment KC and draw an arc centered at K intersecting the second arc.
C. arc IJ and draw an arc centered at K intersecting the second arc.
D. line segment CI and draw an arc centered at I intersecting the second arc.
Thank you.
Answer:
A line parallel to line AB through C & arc IJ and draw an arc centered at K intersecting the second arc
Step-by-step explanation:
This image may result from the construction of a line parallel to line AB through C.
The next step in this construction is to set the compass width to arc IJ and draw an arc centered at K intersecting the second arc.
What is Construction?Geometric constructions are precise drawings of geometrical shapes, angles, and lines. We will need a pencil, a ruler (or other straight edge), and compasses to do this.
Given:
From the image we can see that there is an attempt to make a copy of angle and proceeds to draw a parallel line.
So, This image may result from the construction of a line parallel to line AB through C.
Now, the next step can be measure the arc IJ from compass and put the pointer on K with same measurement and cut the Arc.

There are acres of old-growth trees.
PLEASE HELP
Answer:
128.
Step-by-step explanation:
The equation we need is going to be 32,000 multiplied by 0.04% written as a decimal.
Since 0.04% written as a decimal is 0.004, the equation will be:

iris has $240 in the bank and she withdraws $25 every week. An equation for this relation is C = 240 - 25w, where c represents the amount of money , in dollars, in iris' account and w represents the number of weeks. How much does iris have in her account after 4 weeks
Answer:
140
Step-by-step explanation:
25 x4=100 subtract to the total which is 240 and get 140
Answer:
140
Step-by-step explanation:
Plug 4 into w, so it's C = 240 - 25(4) -> 240 -100 -> C = 140

Answer:
(4 , -3)
Step-by-step explanation:
Put "y" by itself on one side to isolate it
3x - y = 15
3x = 15 + y
3x - 15 = y
Substitute "y" in the second equation for "3x - 15"
x + (3x - 15) = 1
4x - 15 = 1
4x = 16
x = 4
Then, plug 4 into x in any of the equations
4 + y = 1
y = -3
