Answer:
Pennies: 12Dimes: 8Step-by-step explanation:
The number of pennies will be 2 more than a multiple of 10. 2 pennies and 9 dimes is not enough coins. 12 pennies and 8 dimes is exactly enough.
__
This one is easy to figure by "trial and error," as there is only one trial that makes any sense.
If you want to figure it using an equation, it usually works well to let a variable represent the quantity of the higher-value coin. If d is the number of dimes, then 20-d is the number of pennies. The total number of cents is ...
10d +(20-d) = 92
9d = 72 . . . . . . . . . subtract 20
d = 8
20-d = 12
There are 8 dimes and 12 pennies.
Solve the system by elimination
-6x + 6y = 0
9x - 8y = 4
Answer:
Point form: (4, 4)
x = 4, y = 4

Answer:
[tex]\displaystyle n^3-\frac{1}{n^{2}}[/tex]
Step-by-step explanation:
Exponents Properties
We need to recall the following properties of exponents:
[tex](a^x)^y=(a^y)^x=a^{xy}[/tex]
[tex]\displaystyle a^{-x}=\frac{1}{a^x}[/tex]
We are given the expression:
[tex]2^m=n[/tex]
We need to express the following expression in terms of n.
[tex]8^m-4^{-m}[/tex]
It's necessary to modify the expression to use the given equivalence.
Recall [tex]8=2^3 \text{ and }4 = 2^2[/tex]. Thus:
[tex](2^3)^m-(2^2)^{-m}[/tex]
Applying the property:
[tex](2^m)^3-(2^m)^{-2}[/tex]
Substituting the given expression:
[tex]n^3-n^{-2}[/tex]
Or, equivalently:
[tex]\mathbf{\displaystyle 8^m-4^{-m}= n^3-\frac{1}{n^{2}}}[/tex]
Determine the area of the figure, in square meters. HELP ME PLAES BRIANEST ASAP PLEASE HAVE A EXPLIATION
Answer:
100 sq m
Step-by-step explanation:
if you fill in the shape to be a big rectangle it will be 8 x 22 =176 sq m
then the little piece on the left that is taken out is 2 x 2 = 4 sq m
the piece on the right is 6 x 12 = 72 sq m
so subtract them from the big rectangle
176 - 4 - 72 = 100 sq m
Answer:
100m^2
Step-by-step explanation:
To do this we need to break the shape into sections as illustrated in the picture I attached, I color coded the squares to make it easier to explain. Now we just find the area of each shape and add them all together.
Area= base•height
So for the purple shape:
6•2=12
Orange:
8•8=64
Green:
2•12=24
In total:
12+64+24=100
And since it's area it would be in square units which just means it'd look like this:
[tex] {100m}^{2} [/tex]
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Write a piecewise function for the graph.
Similar to Modulus, but It's separated.
Since both are separated, that means - they are both linear function.
The range is greater than all negative numbers. That means y ≥ 0
( 1 ) For the blue graph,
y = -x-3 {y ≥ 0} ---------- Blue Graph Answer
-x-3=0
-x=3
x=-3
We can clearly see that the slope is -1.
And intercept x-axis at (-3,0)
( 2 ) For the red graph.
y = 2x+6 { y ≥ 0} ---------- Red Graph Answer
Notice that the slope is 2.
And intercept x-axis at (-3,0)
Also intercept y-axis at (0,6)
2x+6=0
2x=-6
x=-3
---------- Only linear function with given y ≥ 0 can draw that. (Only separated graph.) --------------
−3x−9y=18
4x+3y=12
Answer:
x = 6 , y = -4
Step-by-step explanation:
Solve the following system:
{-9 y - 3 x = 18 | (equation 1)
3 y + 4 x = 12 | (equation 2)
Swap equation 1 with equation 2:
{4 x + 3 y = 12 | (equation 1)
-(3 x) - 9 y = 18 | (equation 2)
Add 3/4 × (equation 1) to equation 2:
{4 x + 3 y = 12 | (equation 1)
0 x - (27 y)/4 = 27 | (equation 2)
Multiply equation 2 by 4/27:
{4 x + 3 y = 12 | (equation 1)
0 x - y = 4 | (equation 2)
Multiply equation 2 by -1:
{4 x + 3 y = 12 | (equation 1)
0 x+y = -4 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{4 x+0 y = 24 | (equation 1)
0 x+y = -4 | (equation 2)
Divide equation 1 by 4:
{x+0 y = 6 | (equation 1)
0 x+y = -4 | (equation 2)
Collect results:
Answer: {x = 6 , y = -4

What are the solutions to this quadric equation? -2x^2 + x + 4 = 0
Answer:
(1-[tex]\sqrt{33}[/tex])/4 and (1+[tex]\sqrt{33}[/tex])/4
Step-by-step explanation:
-2x^2 + x + 4 = 0
use quadratic formula x= (-b±[tex]\sqrt{b^{2} -4ac}[/tex] ) / 2a
a=-2
b=1
c=4
x= (-1±[tex]\sqrt{1^{2} -4(-2)(4)}[/tex] ) / 2(-2)
x=(-1±[tex]\sqrt{33}[/tex] ) / -4
x=(1 -[tex]\sqrt{33}[/tex]) / 4 and (1 +[tex]\sqrt{33}[/tex]) / 4

PLZ HELP FIFTY POINTS FOR WHOEVER HELPS I NEED THIS ASAP
Answer:
x = 18
y = 54
Step-by-step explanation:
A straight line equals 180 degrees.
Since Lines CD and AB are straight, we can deduce that the angle 3x = 2x + angle AN.
Because there is a right angle, we can subtract 90 -72 = 18.
18 + 2x = 3x
18 = x
A straight line equals 180 degrees. Once we figure out that x = 18, we can figure out y by plugging in x and then subtracting your answer from 180 degrees.

I am trying to find the area of my master bedroom. The measurements are 4x-3(L) 6x-6(W).
the answer keeps coming out to be Zero. And you have to have measurements for the room, so that doesn't make sense.
Substitute x as 4.
Answer:
L= -12
W= -36
Step-by-step explanation:
-12 x -36 = 432
so the area of your master bedroom is 432.
18x + 3y = -21 !!!!!!!!!!
18x+3y=-21
slope -intercept form: y=mx+b
move 18x to the other side
sign changes from +18x to -18x
18x-18x+3y=-18x-21
3y=-18x-21
divide both sides by 3 to find slope-intercept form
3y/3=-18x/3-21/3
y=-6x-7
answer: y=-6x-7

Consider quadrilateral EFGH.
The slope of EF is .
Which statements are true? Check all that apply.
EH is parallel to FG.
EF is perpendicular to EH.
HG is neither parallel nor perpendicular to FG.
Quadrilateral EFGH is a rectangle because it is a parallelogram with four right angles.
Quadrilateral EFGH is a trapezoid because it has exactly one pair of parallel opposite sides.
(B) EF is perpendicular to EH.
Quadrilateral:A quadrilateral in geometry is a four-sided polygon with four sides and four corners (vertices). The Latin words Quadri, a variation of four, and latus, meaning "side," are the source of the name. In reference to other polygons, it is also known as a tetragon, from the Greek "tetra" for "four" and "gon" for "corner" or "angle" (e.g. pentagon). Since "gon" is an anagram for "angle," it is also known as a quadrangle or 4-angle. Display style "square ABCD" is sometimes used to indicate a quadrilateral with the vertices A, B, C, and D.Therefore, the correct option is (B) EF is perpendicular to EH.
