Easy math help picture below 2 problems
Answer:
One line of symmetry.Both rotational and bilateral symmetry.My reasoning for saying both is because the shape is a unique plane. Bilateral symmetry is the term used for when a unqiue shape is folded in any direction and looks the same, while rotational symmetry is when a shape looks the same after a rotated half-turn.
Trick: Fold the shape by the bottom diagonal left side, folding the top left end, then do a rotational turn on the top right corner, fold in the bottom, and it shapes like a rectangle.
Help pls I am confused
Answer:
A. 25 books
Step-by-step explanation:
James has 100 comic books and sells 1/4 of his collection. This means that the amount of comic books that he sold is 1/4 of 100 since 100 is the total amount of comic books that he has. To calculate that, we divide 100 by 4 to get 25. Therefore, James sells 25 books.

trinomials method can i have some help?
Answer:
a: 3/2, -2 b: 1/5, -1/2 c: 3/2, -4
Step-by-step explanation:
a: 2x^2+x=6
Subtract 6 from both sides.
2x^2+x−6=6−6
2x^2+x−6=0
Factor left side of equation.
(2x−3)(x+2)=0
Set factors equal to 0.
2x−3=0 or x+2=0
b: 10a^2+3a=1
Subtract 1 from both sides.
10a^2+3a−1=1−1
10a^2+3a−1=0
Factor left side of equation.
(5a−1)(2a+1)=0
Set factors equal to 0.
5a−1=0 or 2a+1=0
c: 2c^2+5c=12
Subtract 12 from both sides.
2c^2+5c−12=12−12
2c^2+5c−12=0
Factor left side of equation.
(2c−3)(c+4)=0
Set factors equal to 0.
2c−3=0 or c+4=0

Step-by-step explanation:
Out of 260 racers who started the marathon, 232 completed the race, 25 gave up, and 3 were disqualified. What percentage did not complete the marathon?
Answer:
9
Step-by-step explanation:
You're looking for the percentage that "did not complete the marathon" So take the 25 that gave up and the 3 that were disqualified and add those. Then divide 260 by your sum of those groups. Your expresssion should be 260/28 which gives you the decimal 9.28571429. Your answer would be 9 because this question doesn't ask for a decimal answer.

Find the Value of X. or other X finders. (worth 10 points)
Answer:
First, if we look at these angles, we can see that they are vertical.
Vertical angles are congruent(meaning they measure the same degrees).
So let's set up an equation where -2x - 6 is equal to 40°, because they are vertical angles.
-2x - 6 = 40°
Solve for x!
Get rid of constants by performing the inverse operation of subtraction which is addition(because 6 is negative).
Make sure to apply this to both sides!!
(Add 6 to both sides)
+6 +6
-2x = 46
Now, we isolate x by getting of x's co-efficient.
To do that, we also perform the inverse operations.
The inverse operation of multiplication is division (since -2 is being multiplied by x).
(Divide -2 from both sides)
÷ -2 ÷ -2
x = -23
Therefore, x measures -23°.
Answer:
x = -23
Step-by-step explanation:
Vertical Angle Theorem
A pair of opposite angles formed by intersecting lines.
Vertical angles are congruent.
⇒ -2x - 6 = 40
Add 6 to both sides:
⇒ -2x = 46
Divide both sides by -2
⇒ x = -23

Write an equation of the circle with center (-5,2) and diameter 6.
Answer:
[tex](x+5)^2+(y-2)^2=36[/tex]
Step-by-step explanation:
The equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center and [tex]r[/tex] is the radius, thus:
[tex](x-h)^2+(y-k)^2=r^2\\(x-(-5))^2+(y-2)^2=6^2\\(x+5)^2+(y-2)^2=36[/tex]
This means that our equation for the given circle is [tex](x+5)^2+(y-2)^2=36[/tex]
A bookstore has 36 copies of the latest bestseller and they fit exactly on 3 shelves. The bookstore ordered another 120 copies. How many shelves do they need to fit all their copies of the book?
Answer:
13
Step-by-step explanation:
First, to find out how many book fit on one shelf, you will need to divide the total number of books by the toal number of shelves:
36 books / 3 shelves = 12 books/shelf
Because the question says that the bookstore order another 120 copies, this is means that the 120 books is in addition to the original 36 books.
Because we already know that the 36 books require 3 shelves, we still need to find how many shelves 120 books needs. So, we can divide books by number of how many books can fit on a shelf:
120 books / 12 books per shelf = 10 shelves
So to find the total number of shelves needed, add the number of shelves together:
3 + 10 = 13 shelves

Which inequality represents “six times a number is less than negative thirty-nine and three-quarters”?
6x > –39Three-fourths
6 + x > -39 Three-fourths
6x < -39Three-fourths
6 x less-than-or-equal-to negative 39 and three-fourths
Answer:
6x<-39+¾
Step-by-step explanation:
let the number be represented by x.
Answer: The third option is correct.
Step-by-step explanation: 6x means "six times a number", which the unknown number is x. The less-than sign shows the "less than" part of the equation, and -39 3/4 represents the "negative thirty-nine and three-quarters". Hope this helps, also i got it right on edge.

pls answer fast
Answer:
[tex]x = \frac{2}{21} [/tex]
Step-by-step explanation:
That's the correct answer
Step-by-step explanation:
What did u want
Rewriting in standard form:
[tex]2x - 6y = - 21[/tex]
X - intercept:
[tex]x = - \frac{21}{2} [/tex]
y intercept:
[tex]y = \frac{7}{2} [/tex]
y = 1/3x + 7/2
so the slope is 1/3
Evaluate the algebraic expression t + s - r when r = 13, s = 10, t = 7 and u = 15.
A. 2
B. 4
C. 16
D. 30
Answer:
4
Step-by-step explanation:
t + s - r
where,
r=13
s=10
t=7
u=15
substituting
7+10-13 =17-13 =4
Hey there!
t + s - r
= 7 + 10 - 13
= 17 - 13
= 4
Therefore, your answer might be:
Option B. 4

Answer:
[tex] c^{-1}d^7 [/tex]
Step-by-step explanation:
You are multiplying factors with the same base, so add the exponents of the same base.
c^0d^7 × c^-1d^0 = c^0c^-1 × d^7d^0 = c^(0-1)d(7+0) = c^-1d^7
Answer: (dc)⁶
Step-by-step explanation:
Apply exponent rule: a⁰=1
This means c⁰=1 and d⁰=1 leaving the equation d⁷·c⁻¹
This then becomes d⁷/c though since they don't want a denominator we will have to change it.
Apply quotient rule of exponents: aᵇ÷aⁿ=aᵇ⁻ⁿ
This leaves us with (dc)⁶
Which expression is equivalent to x^2+7x+12 over x^2-x-12
Answer:
Step-by-step explanation:
Factorize the expression.
Sum = 7
Product = 12
Factors = 4 , 3
4 + 3= 7 & 4*3 = 12
x² + 7x + 12 = x² + 4x + 3x + 4*3
= x(x + 4) + 3(x + 4)
= (x + 4)(x + 3)
Sum = -1
Product = -12
Factors = (-4) , 3
(-4) + 3 = (-1) & (-4)*3 = -12
x² - x - 12 = x² - 4x + 3x - 4*3
= x(x - 4) +3(x - 4)
= (x -4)(x +3)
[tex]\sf \dfrac{x^{2}+7x+12}{x^{2}-x-12}=\dfrac{(x+4)(x + 3)}{(x -4 )(x + 3)}\\\\\bf \text{(x +3) in the numerator and denominator will get cancelled}[/tex]

[tex]7^{\frac{9}{4}}= \sqrt[4]7^{9}\implies\sqrt[c]a^{b}[/tex]
On comparing, we find:
a = 7, b = 9, c = 4
Answer:
[tex] \sf \: a = 7,\: b = 9,\: c = 4[/tex]
Step-by-step explanation:
[tex] {7}^{\frac{9}{4}} [/tex] we have to write in the form [tex] \sf \: {}^{c} \sqrt{ {a}^{b} } [/tex]
[tex] {a}^{ \frac{1}{b} } = {}^{b} \sqrt{a} [/tex]
[tex] {a}^{b} = {a}^{b}[/tex]
from there we can write.
[tex] {7}^{3 \times \frac{1}{4} } = {}^{4} \sqrt{ {7}^{9} } [/tex]
Comparing with [tex] \sf \: {}^{c} \sqrt{ {a}^{b} } [/tex]
c = 4 , b = 9, a = 7

The answer is C
Answer:
Step-by-step explanation:
Louise: Water = 4.6 + 1.2*t gallons of water
Isaac: Water = 54.6 - 0.8 * t t is in minutes.
When will the two amounts of water be equal
When the two waters are the same.
4.6 + 1.2*t = 54.6 - 0.8t Add 0.8t to both sides
4.6 + 1.2*t + 0.8*t = 54.6 Combine the left
4.6 + 2t = 54.6 Subtract 4.6 from both sides.
4.6-4.6 + 2t = 54.6 - 4.6 Combine
2t = 50 Divide by 2
t = 50/2
t = 25
Answer: both aquariums will have the same amount of water in 25 min

The area of a rectangular piece of paper is 1/2 square foot
Answer:
(D)
Step-by-step explanation:
The area of a rectangle is the product of length and width. We can solve this formula to find the width:
A = LW
W = A÷L . . . . . . divide both sides of the equation by L
__
For the given area and length, this looks like ...
