Answer:
8x
Step-by-step explanation:
perimeter is sum of all sides
square has 4 equal sides
each side measures '2x'
2x + 2x + 2x + 2x = 8x or 4(2x) = 8x
Can someone answer this please
3. Michael says he can move ABCDE onto A"B"C"D"E" with one transformation by translating ABCDE diagonally so that it moves 8 units up and 10 units right. Is he correct? Explain why or why not.
Answer:
Yes, he is correct
Step-by-step explanation:
if you translate each letter ABCDE to A"B"C"D"E" exactly how he stated it turns out right. For example, C just go 8 squares up and then 10 to the right and do the same for the rest.
Answer:
Michael is incorrect; The shape would have to be flipped at some point, seeing as point B on ADCDE is on the bottom of the shape, whereas point B" on A"B"C"D"E" is on the top of the shape.
Hope this helps, have a nice day!
Step-by-step explanation:
Wait a sec... I'm Michael, so am I right or am I wrong...? (Big confuse)

9514 1404 393
Answer:
D. (-3, -2)
Step-by-step explanation:
The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.
Using (x, y) = (-2, -3):
x = y -1 ⇒ -2 = -3 -1 . . . . False
Using (x, y) = (-3, -2):
x = y -1 ⇒ -3 = -2 -1 . . . .True
2x = 3y ⇒ 2(-3) = 3(-2) . . . . True
The solution is (-3, -2).
__
If you'd like to solve the set of equations, substitution for x works nicely.
2(y -1) = 3y
2y -2 = 3y . . eliminate parentheses
-2 = y . . . . . . subtract 2y
x = -2 -1 = -3
The solution is (x, y) = (-3, -2).
Find the unknown side length, x. Write your answer in simple
Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 32² = 48²
x² + 1024 = 2304 ( subtract 1024 from both sides )
x² = 1280 ( take the square root of both sides )
x = [tex]\sqrt{1280}[/tex]
= [tex]\sqrt{256(5)}[/tex]
= [tex]\sqrt{256}[/tex] × [tex]\sqrt{5}[/tex]
= 16[tex]\sqrt{5}[/tex] → C
Solve using substitution:
3x + y = 14
2x - 6y = -24
Answer:
(x,y)=(3,5)
Step-by-step explanation:
Answer:
x = 3
y = 5
Step-by-step explanation:
*tip = chose a variable and get by itself one side and then plug it into the other equation
3x + y = 14
y = -3x + 14
2x - 6(-3x + 14) = -24
2x + 18x - 84 = -24
20x = 60
x = 3
3(3) + y = 14
9 + y = 14
y = 5
2. A snail weighed s ounces. One day the snail drank 5 times its weight in water and ate half its weight in food. Which equation can be used to find t, the combined weight of the water and the food, in ounces, that the snail had on this day?
A t= s + 5 - 1/2
B T= s +5 + 1/2
C t= 2s + s/5
D t= 5s + s/2
Answer:
Option D : t = 5s + s/2 is the correct answer.
Step-by-step explanation:
Given that:
t = Combined weight of water and food
s = weight of the snail
Water drank by snail = 5s
Food ate by snail = s/2
Combined weight = Weight of water + Food
t = 5s + s/2
Hence,
Option D : t = 5s + s/2 is the correct answer.
u(x) = -x+2
w (x) = x² +1
Find the value of w (u(4)).
Answer:
Use the given functions to establish and reduce u (4)
x=x2+1=x=1+i√32,1−i√32
w=x=1+i√32,1−i√32
u(4)=4u
Step-by-step explanation:
Answer:
5, probably
Step-by-step explanation:
you are looking for the function w(u(4)). you need to find u(x) first when x=4 so solve for u(4)=-x+2 so u(4)=-4+2=-2. now plug this -2 value into the function w(x) so w(-2)=-2^2+1 so basically =4+1 and I think that is probably 5 maybe the value of w(u(4))=5

3.TAXIS To take a cab from Rosa's house to the library costs her $26. If this is $18 less than what it costs her to take a cab to the airport, what does that fare cost?
Answer:
$8
Step-by-step explanation:
Given
Cost of fare from house to library
=$26
Let the fare to the airport be x
26=x-18
Solve for x
26-18=x
x=$8
Hence the fare is $8

use substitution to write an equivalent quadratic equation
(3x + 2) ^2 + 7(3x+2) - 8= 0
Answer Step-by-step explanation:
Let z = 3x +2. Then the equivalent quadratic equation can be written as
z² +7z -8 = 0
_____
This can be factored as
(z -1)(z +8) = 0
which has solutions
z = {1, -8}.
Then the corresponding values of x are found from
z = 3x +2
z -2 = 3x
(z -2)/3 = x
For z = 1,
(1 -2)/3 = x = -1/3
For z = -8
(-8 -2)/3 = x = -10/3

Solve for x in the following figure.
Answer:
x = 80
Step-by-step explanation:
All angles in a triangle add up to 180 degrees.
First, find the angle J:
60+40 = 100, J = 80 because 100+80= 180 degrees.
Now, the two angles on either side of J should also equal 180 degrees. We know that the inner angle is equal to 80 degrees. Thus, the outside angle must equal 100.
x + 20 = 100
x = 80 degrees.
5/6+8b whats the sum or quotient
Answer:
Quotient: 5/6
Product: 8b.
Sum: 5/6 + 8b
Step-by-step explanation:
While translating the problems into mathematical expression or mathematical expression in English, Kind of Expression can be used. Mostly in the algebraic parts.
Quotient: It represents that one value is divided by the another value. It is also known as the ratio.
i.e: 5/6
Product: It means multiplying either a known value and unknown variables or both unknown variables.
i.e.: 8b.
Sum: It means adding either a known value and unknown variables or both unknown variables.
i.e. : 5/6+8b
Write the equation of the line that passes through (4,2) and has a slope of -2 in
POINT SLOPE FORM. y - y1 = m(x - x1)
Answer:
y = -2x + 10
Step-by-step explanation:
The equation in point slope form is expressed using the equation
y - y1 = m(x - x1) where;
m is the slope = -2
(x1, y1) is the point on the line = (4,2)
Substitute into the formula:
y - 2 = -2(x - 4)
y -2 = -2x + 8
y = -2x +8 +2
y = -2x + 10
Hence the required equation of the line is y = -2x + 10
