Explanation:
it is x=1 because if the point (-1,3) is reflected then the other point is (3,3) and so on
The ratio of pencils to pens is 3 to 5. There are 21 pencils in the classroom. How
many total pens and pencils are in the classroom?
Answer:
56 pencils and pens
Step-by-step explanation:
3:5 is the ratio, and then put that into a fraction and then make a proportion
3/5=21/x
eCross multiply and divide so do 21*5 divided by 3. This gives us an answer of 35. Now we know we have 35 pens. 35+21, adding the pen and pencil, is 56. You can always also look for relationships, so if you could see that multiplying 7 gives you the answer, than do that to the 5, and then add it together.

What is the next term of the geometric sequence? 20, -10 ,5,?
Answer:
-2.5
Step-by-step explanation:
The common ratio of the sequence is -0.5, because as the sequence progresses, the new number is obtained by multiplying the previous one by -0.5
So, to find the next term, multiply 5 by -0.5
5(-0.5)
= -2.5
So, the next term is -2.5

Step-by-step explanation:
The area of rectangle is 3[tex]c^{6}[/tex]-12[tex]c^{5}[/tex] + 9[tex]c^{4}[/tex].
What is area of rectangle?The area of any rectangle is calculated, once its length and width are known. By multiplying length and breadth, the rectangle's area will obtain in a square-unit dimension.
Area of a Rectangle. A = l × b.
Given:
height = 3[tex]c^{4}[/tex]
width = c² - 4c +3
So, Area of rectangle
=length * width
= 3[tex]c^{4}[/tex] * (c² - 4c +3)
=3[tex]c^{6}[/tex]-12[tex]c^{5}[/tex] + 9[tex]c^{4}[/tex]
Hence, the area of rectangle is 3[tex]c^{6}[/tex]-12[tex]c^{5}[/tex] + 9[tex]c^{4}[/tex].

What is the next number in the sequence: -2, 4, -8, 16, -32, , ...
Answer:
64
Step-by-step explanation:
This is an Geometric sequence
Common ratio = 2nd term ÷ 1st term = 4 ÷ (-2) = -2
To get the next term multiply the previous term by (-2)
The next term (6th term) = -32 * (-2) = 64
So what is a dilation and how will it effect the image and the preimage(i have 8th grade math).
Answer:
In geometry, a transformation is an operation that moves, flips, or changes a shape to create a new shape. A dilation is a type of transformation that enlarges or reduces a figure (called the preimage) to create a new figure (called the image).

An equation for a line that is perpendicular to the line given by y=-2 and passes through the point (5,6)
Answer:
y - 6 = 1/2 (x - 5)
Step-by-step explanation:
Point slope equation: y-y₁ = m(x-x₁)
replace
x₁ = 5,
y₁ = 6,
m = 1/2 (perpendicular means opposite reciprocal)
Find the height a 17-foot ladder can reach on the side of a building when it
hits the ground at a 65° angle.
A. 7.2 ft
B. 15.4 ft
C. 36.5 ft
D. 48 ft
E 224 ft
SHOW EXPLANATION
Answer:
B. 15.4 ft
Step-by-step explanation:
this answer, without any formulas used, can be answered correctly and logically.
answer c, d and e are eliminated as the opposite side cant be greater than the hypotenuse.
now we have to find which is correct between a and b
the answer will be 'B' as the value of sine of an angle keeps increasing as the angle itself increases. thus, giving a bigger value of the opposite side (required height). as 15.4 ft.
mathematically,
sin65° = x/17
17 × sin65° = x
where x is height of the side of the building.
Probability a bag of miniature candy’s contain 15 crunch bars 14 Hershey’s chocolate bars 10 Mr.Goodbars 12 Hershey’s cookies and cream bars. What is the probability of randomly choosing each of them ?
15:51 for Crunch bars
14:51 for Hershey's
10:51 for Mr. Goodbars
12:51 for Cookies and Cream
There are 51 candies in total. We got that by adding all of the candies together. 15 + 14 + 10 + 12 = 51. The probability can be written as a ratio between the different types of candy and the whole number.
The probability of crunch bars, Hershey’s chocolate bars, Mr.Goodbars, and Hershey’s cookies and cream bars are 15/51, 14/51, 10/51, and 12/51, respectively.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability can be written as,
P(Crunch bars) = Number of Crunch bars/ Total number of choclates= 15/51
P(Hershey's Chocolate) = 14/51
P(Mr. Goodbars) = 10/51
P(Hershey’s cookies and cream bars) = 12/51
Hence, the probability of crunch bars, Hershey’s chocolate bars, Mr.Goodbars, and Hershey’s cookies and cream bars are 15/51, 14/51, 10/51, and 12/51, respectively.

Answer:
∠ABD = 48
Step-by-step explanation:
use symbolab
(x+15)=(4x-12)
x+15-15=4x-12-15
x=4x-27
x-4x=4x-27-4x
-3x=-27
divide both sides by 3 and you get x=9
then put 9 in to replace x
((9) + 15) + (4 (9) - 12)
=24 + (4 (9) - 12)
= 24 + 24

Answer:
(1/3)x+ x-20+ x-10+40= 360
Step-by-step explanation:
(1/3)x+ x-20+ x-10+40= 360
x+3x-60+3x-30+120=360*3
7x+30= 1080
7x= 1050
x= 150
The sum of the angles = 360.
Add the 4 angles together so they equal 360:
1/3x + x-20 + x-10 + 40 = 360
Combine like terms:
2 1/3x - 30 + 40 = 360
Continue combining like terms:
2 1/3x +10 = 360
Subtract 10 from both sides:
2 1/3x = 350
Divide both sides by 2 1/3:
x = 150
Line J M is the perpendicular bisector of LK.
Line J M intersects line L K at point N and forms a right angle.
Which segments are congruent?
JN and LN
JN and NM
LN and NK
NK and NM
Answer:
The congruent segments are LN and NK ⇒ C
Step-by-step explanation:
If a line is a perpendicular bisector of another line, that means this line intersects the other line in its midpoint and form right angles around this point
∵ Line JM is the perpendicular bisector of line LK
→ That means JM intersect LK at the midpoint of LK
∵ Line JM intersects line LK at point N
∴ Point N is the midpoint of LK
∵ N divides LK into two segments LN and NK
∵ N is the midpoint of LK
→ That means LN equals NK
∴ LN = NK
∴ The congruent segments are LN and NK

Answer:
36x^8
Step-by-step explanation:
You distribute the exponent (2) to the the coefficient (6) and the other exponent (4). When you distribute 2 to 6 you are squaring the 6.
6^2 = 6•6 = 36
Because of the power rule, you just multiply both the exponents together.
4•2 = 8
so when you put it together it looks like this: 36x^8

Answer:
Saturday
Step-by-step explanation:
First we have to find the LCM of 3 and 4
It is 12, so we know that she will jog and swim every 12 days
This time was Monday, so 12 days after Monday will be the day she both jog and swims.
12 days after Monday is Saturday, so the next time she jogs and swims is Saturday.

Answer:

Step-by-step explanation:
Using the trigonometric identity
tan²x + 1 = sec²x
Consider the left side
[tex]\frac{1+sin^4A}{cos^4A}[/tex]
= [tex]\frac{1}{cos^4A}[/tex] + [tex]\frac{sin^4A}{cos^4A}[/tex]
= [tex]sec^{4}[/tex] A + [tex]tan^{4}[/tex] A
= (tan²A + 1)² + [tex]tan^{4}[/tex] A
= [tex]tan^{4}[/tex] A + 2tan²A + 1 + [tex]tan^{4}[/tex] A
= 1 + 2tan²A + 2[tex]tan^{4}[/tex] A ← factor out 2tan²A
= 1 + 2tan²A(1 + tan²A)
= 1 + 2tan²A sec²A

Mr. Drew grows green pepper plants in planters.
The graph shows the relationship between the number of planters and the number of pepper plants. How many pepper plants are in 3 planters?
A graph shows green pepper plants by planters. A line starts at (0, 0) and passes through (4, 12).
18
12
9
3
Answer:
Option (3)
Step-by-step explanation:
From the graph attached,
For a point (x, y),
x-coordinate shows the planters and y-coordinate show the number of green pepper plants in the planters.
If input value (x-value) for the line is 3,
Output value (y-value) from the graph will be, y = 9.
Therefore, there are 9 green pepper plants in 3 planters.
Therefore, Option (3) is the correct option.
