Step-by-step explanation:
Hope this helps!!!
Answer:
x= 62/17
Step-by-step explanation:
17x - 4+4 = 58 + 4
17x= 62

Quadratics Help!!! (Number 11)
Answer:
a) 2x + 1, 4x + 7
b) L = 19 cm, W = 7 cm, A = 133 cm^2
Step-by-step explanation:
8x^2 + 18x + 7
ax^2 + bx + c
ac = 8 * 7 = 56
56 = 4 * 14
8x^2 + 18x + 7 =
= 8x^2 + 14x + 4x + 7
= 2x(4x + 7) + 1(4x + 7)
= (2x + 1)(4x + 7)
a) 2x + 1, 4x + 7
b)
2(3) + 1 = 7
4(3) + 7 = 19
A = LW = 19(7) = 133
Quadrilateral ABCD is dilated by a scale factor of 3/2 to create quadrilateral A'B'C'D'. If quadrilateral ABCD has an area of 30, what is the area of quadrilateral A'B'C'D'?
Answer:
67.5
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.
Dilation is the enlargement or reduction of an object by a factor.
The area of ABCD = AB * BC = 30
As a result of the dilation to form A'B'C'D', A'B' = 3/2 * AB, B'C' = 3/2 * BC, C'D' = 3/2 * CD and A'D' = 3/2 * AD. Hence:
Area of A'B'C'D' = A'B' * B'C' = 3/2 * AB * 3/2 * BC = 9/4 * (AB * BC) = 9/4 * 30 = 67.5
Answer:
the transformation quadrilateral ABCD undergoes is a reflection.

which expression results from using the distributive property: 7(x+3)
factor: m^2 - 20m - 21
(m-21) (m+1)there I thinks it's right unless I messed up my work
Answer:
[tex](m - 21)(m + 1)[/tex]
Step-by-step explanation:
[tex]m^{2} - 20m - 21[/tex]
Lets split the middle term.
[tex]=> m^{2} - 21m + m - 21[/tex]
[tex]=> m(m - 21) + 1(m - 21)[/tex]
[tex]=> (m - 21)(m + 1)[/tex]
please help! it’s due today haha it’s pythagoras
Answer:
x = 6.22 cm
Step-by-step explanation:
The lines on the sides of the triangle means they are the same length
Since it is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
Substituting what we know
a^2 + a^2 = x^2
a=4.4
(4.4)^2 + (4.4) ^2= x^2
19.36 + 19.36 = x^2
38.72 = x^2
Taking the square root of each side
6.222539674 = x
Rounding to 3 significant figures
x = 6.22 cm
It takes 198198198 seconds to boil a perfect egg at the lowest place possible, the edge of the Dead Sea, which has an altitude of -418−418minus, 418 meters. The highest place possible is the summit of Mount Everest which has an altitude of 884888488848 meters. It takes 209209209 seconds to boil a perfect egg there. T(a)T(a)T, left parenthesis, a, right parenthesis models the time (in seconds) it takes to boil a perfect egg at an altitude of aaa meters.
Given that,
An egg takes 198 seconds to boil a perfect egg has an altitude of -418 m.
Also it takes 209 seconds at an altitude of 8848 m.
To find,
The domain of T.
Solution,
Domain is the set of input values for which the function is defined. The least value is -418 m and the highest value is 8848 m. So, the domain is :
[tex]-418\le x \le 8848[/tex]
Therefore, this is the required solution.
Answer:

If one of the angle is 60 degree and the other two are in the ratio 1:2,
find the angles.
Answer:
Let the two angles be x and 2x
Sum of angles of triangle=180°
60+x+2x=180
3x=180-60
x=120/3
x=40
2x=80
Step-by-step explanation:
40 and 80 are other two angles

jackie is solving this system of linear questions: 3x+2y= 20
4x-y=30
which equations could be part of the process of solving this system?
4x+6y=20
12x+8y=80
8x-y=60
8x-2y=60
Answer: 12x+8y=80
8x-2y=60
Step-by-step explanation:
The equations that could be part of the process of solving this system are 12x+8y=80 and 8x-2y=60.
The original equation was 3x+2y= 20 and 4x-y=30. Multiplying all through by 4 gives 12x+8y=80 and 8x-2y=60.
Triangle ABC is a right triangle. Triangle A B C is a right triangle. Angle A C B is 90 degrees, angle C B A is 31 degrees, and angle B A C is 59 degrees. What is the relationship between angles A and B?
Answer:
see explanation
Step-by-step explanation:
Complementary angles sum to 90°
∠ CBA = 31° and ∠ BAC = 59° , sum to 90° (31° + 59° = 90° )
Thus
∠ A and ∠ B are complementary angles
Answer: They are complementary

what is the constant of variation in this relation?
Answer:
Please check the explanation.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
k = y/x
here k is the constant of variation.
From the table,
substitute x = -3, y = -4 in the equation
k = y/x
k = -4/-3
k = 4/3
substituting x = -2, y = -1
k = y/x
k = -1/-2 = 1/2
substituting x = -1, y = 2
k = y/x
k = 2/-1 = -2
substituting x = 0, y = 5
k = y/x
k = 5/0 = ∞
substituting x = 1, y = 8
k = y/x
k = 8/1
k = 8
substituting x = 2, y = 11
k = y/x
k = 11/2
substituting x = 3, y = 14
k = y/x
k = 14/3
It is clearly visible that there is no constant of variation because the ratio y = k/x is variating for different ordered pairs.
Thus, It is clear that none of the answers in the answer choices represent the constant of variation in this relation.
