Help! Find the domain of the graph
Answer:
[-8,4]
Step-by-step explanation:
you look at the x-axis. The end points of the graph are -8 and 4, thus the domain would be [-8,4] as it is always written in left to right or bottom to top value.

The expression ax²+bx+c is divisible by x-1, has a
remainder of 2 when divided by x+1 and has a remainder of 8 and when divided by x-2 find the values of a, b, and c and
factorise completely.
Answer:
(x - 1)(3x + 2)
Step-by-step explanation:
By the Remainder theorem
Given expression is divisible by x - 1 then f(1) = 0
when divided by (x + 1) then f(- 1) = 2
when divided by x - 2 then f(2) = 8
Substitute x = 1, x = - 1, x = 2 into the expression , that is
a + b + c = 0 → (1)
a - b + c = 2 → (2)
4a + 2b + c = 8 → (3)
Subtract (1) from (2) to eliminate a and c
- 2b = 2 ( divide both sides by - 2 )
b = - 1
Subtract (1) from (3) to eliminate c
3a + b = 8 ← substitute b = - 1
3a - 1 = 8 ( add 1 to both sides )
3a = 9 ( divide both sides by 3 )
a = 3
Substitute a = 3, b = - 1 into (1) and evaluate for c
3 - 1 + c = 0
2 + c = 0 ( subtract 2 from both sides )
c = - 2
Then a = 3, b = - 1, c = - 2
Thus
ax² + bx + c
= 3x² - x - 2
= (x - 1)(3x + 2) ← in factored form

ayo um can i get help Please just show your work and tell what the area is
Answer:
320 inches
Step-by-step explanation:
First, split the figures into 2. 1 short rectangle and long rectangle.
Find the area of the longer rectangle first.
Length = 16 + 8 = 24 in
Breadth = 16 - 8 = 8 in
Formula for area of rectangle = Length x Breadth
24 in x 8 in = 192 in (Area of long rectangle)
Find the area of the short rectangle.
Breadth = 16 - 8 = 8 in
16 x 8 = 128 in (Area of short rectangle)
Since they're combined,
192 + 128 = 320
I don't know if this is correct, but I hope it was helpful)

Apply the 45º-45º-90º Triangle Theorem to find the length of a leg of a right triangle if the length of the hypotenuse is 8{x} inches.
9514 1404 393
Answer:
(4√2)x inches
Step-by-step explanation:
The leg of an isosceles right triangle is (√2)/2 times the length of the hypotenuse. For a hypotenuse of 8x inches, the leg length is ...
(8x)(√2)/2 = (4√2)x . . . inches
In the diagram below, AC intersects ABDE at B. Choose True or False for each statement
Answer:
false, true . false
Step-by-step explanation:
if u want an explanantion you can ask me :)
Answer: a. True b. True c. False
Explanation:
a. 65+25 =90 complementary angles add up to 90°
b. 65 + b + 25 = 180
90 + b = 180
b = 180 - 90
b = 90
Check-
65 + 25 + 90 = 180
90 + 90 = 180
180 = 180 ✅
c.not vertical angles because they aren’t across from eachother
a rectangular swimming pool is 15 feet long and x feet wide. What is the perimeter when x=12 feet
Answer: 54 square feet
Step-by-step explanation:
To find perimeter of a rectangle we must use the formula l+l+w+w=p where l and w represent width and length
Since we know length and width is x=12 just substitute so
15+15+12+12=54 so 54 is the perimeter

Two trains, train a and train , weigh a total of 466 tons. Train A is heavier than train b. The difference of there weights is 326 tons. What is the weight of each train
Answer: A = 396 tons
B = 70 tons
Step-by-step explanation:
From the question,
Weight of A + Weight of B = 466
Weight of A - Weight of B = 326
A + B = 466 ......... i
A - B = 326 ..........ii
Subtract equation ii from I
2B = 140
B = 140/2
B = 70 tons
A = 466 - 70
A = 396 tons
PLEASE ANSWER!! A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of
the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. Complete
sentences
Answer:
Volume of prop = 706.5 in³
Step-by-step explanation:
Given:
Radius = 5 in
Height = 17 in
Find:
Volume of prop
Computation:
Volume of prop = Volume of cone + Volume of hemi-sphere
Volume of prop = 1/3(π)(r²)(h) + 2/3(π)(r)³
Volume of prop = 1/3(3.14)(5²)(17) + 2/3(3.14)(5)³
Volume of prop = 444.83 + 261.67
Volume of prop = 706.5 in³

3(x - 7) = 2(x - 12)
explain how u got it too
Answer:
x = -3
Step-by-step explanation:
3x - 21 = 2x - 24
3x = 2x - 3
x = -3
Answer:
x = 45
Step-by-step explanation:
First, we need to use the distributive property on both sides of the equation. We multiply the number outside of the parentheses by every term inside the parentheses.
3(x - 7) = 2(x - 12)
3x - 21 = 2x - 24
From here, we solve for x.
3x - 21 = 2x - 24
x - 21 = 24 (Subtract 2x from both sides)
x = 45 (Add 21 to both sides)
