Use the rules of equations and inverse operations to solve the equation. In your final answer, include all of your work. 4 -x^2 = -16
Answer:
±2√5
Step-by-step explanation:
4 -x^2 = -16 can be rewritten as
20 = x^2.
This quadratic has two solutions: find them by taking the square root of both sides:
x = ±√20 = ±√4√5 = ±2√5
If the fraction 384/x -10 is equivalent to -24, find the value of x. Show your work.
Use reasoning to find x.
384/x -10= Blank.
Answer:
x=-6
Step-by-step explanation:
384/x -10=-24
384=-24(x -10)
384=-24x+240
384-240=24x
-144=24x
-144/24=x
x=-6
PUTTING x=-6 in 384/x -10
384/-6-10
384/-16
=-24

what is: 9+8*2-9+30*1100/2
Answer:
16516
Step-by-step explanation:
what value of y makes the equation true?
3 ( 2y - 5 ) + 15 = 12
y =
To find value of y:-
________________________________
Step 1:
3 ( 2y - 5 ) + 15 = 12
Right the equation
________________________________
Step 2:
6y-15+15=12
open the brackets and multiply 3 with 2y - 5
________________________________
Step 3:
6y=12
Subtract 15 with 15 to get 0
________________________________
Step 4:
y=12÷6
divide 12 with 6 to get value for y
________________________________
Step 5:
y=2
Value of y comes 2
________________________________
Confermimng :
3(2×2-5)+15=12
3(4-5)+15=12
3(-1)+15=12
-3+15=12
12=12
hence proved
________________________________
⚡Final answer:
Y=2✓
We have to keep value of y as 2 to make the equation true✓
In 2 - 4 sentences explain where you might see and use scale factoring in your everyday life and how it is useful.
Answer:
2-4--2
Step-by-step explanation:
Answer:
An example of scale factoring that could be used in everyday life is when modeling. When modeling and object you don't make it, for example, 10 feet because that cannot fit on a computer screen. So when on a computer you see a much smaller-scale version.

Answer:
(C) [tex]7+9\cdot8[/tex]
Step-by-step explanation:
We can break this expression down into parts.
The product of 9 and 8
When we see product, we know it's multiplication. So we can create the part of the expression [tex]9\cdot 8[/tex]
7 more than
More than means we add to whatever is to the right of this. Since the product of 9 and 8 is to the right, we add 7 to it.
[tex]9\cdot 8 + 7[/tex]
And now we can rearrange terms to get [tex]7+9\cdot8[/tex].

Find the area of each shaded region. Show your reasoning.
LA
B
d
Using the strategies
previously discussed
(decomposing and
composing)
, find the
area of the three
shaded figures below.
Remember that you
can count the squares
as your easiest
strategy,
but I would like for
you to use a
mathematical
strategy to find the
area of the shaded
regions. Beware of
the squares in Figure
C that are not whole
units.
Answer
A- 22 square units
B- 28 square units
C- 18 square units
Step-by-step explanation:
A. You can break it up into 3 different rectangles
(1*2)+(2*4)+(2*6)=22
B. You can first start by finding the area then subtracting the the places where it is not covered.
So the area of the whole square is 6*6=36
Now you can subtract the small squares 2*2=4.
This will be put 2 times as there are two small squares.
So you will subtract 8 square units from 36.
36-8=28
C- You can decompose C into a triangle and a rectangle.
The area of a triangle is 1/2*width*height. When you plug the dimensions in you get 1/2*6*2=6 square units.
Now to find the rectangle. The formula is width*length. Plug the dimensions in and you get 2*6=12 square units.
Just add those two together and you get 18 square units.
