Answer:
[tex]x=-\dfrac{41}{14}[/tex]
Step-by-step explanation:
[tex]7(2x+6)=1[/tex]
Expand parentheses:
[tex]14x+42=1[/tex]
Subtract 42 from both sides:
[tex]14x=-41[/tex]
Divide both sides by 14:
[tex]x=-\dfrac{41}{14}[/tex]
Hope this helps!
Answer:
x = -41/14
Step-by-step explanation:
7(2x+6)=1
Distribute
14x +42 =1
Subtract 42 from each side
14x+42-42 = 1-42
14x = -41
Divide each side by 14
14x/14 = -41/14
x = -41/14

If the height is changed to 3, does this have the same effect on the volume as changing the radius to 1?
If the height is now 3, then the new volume is π units3.
If the radius is now 1, then the new volume is π units3.
Therefore, changing the height to half of its original value and changing the radius to half of its original value does the volume. Halving the height of the cone the volume, while halving the radius of the cone results in the volume.
Answer:
4, 2, not have the same effect on, halves, 1/4
Step-by-step explanation:
pleeeeeez mark brainliest
Halving the height of the cone halves the volume, while halving the radius of the cone results in 1/4 the volume.
How to find the volume of a cone?
We are given a right cone with;
radius = 2
height 6
volume is; V = ¹/₃π(2)²6 = 8π units³
If the height is now 3, then the new volume is;
¹/₃π(2)²3 = 4π units.
If the radius is now 1, then the new volume is;
¹/₃π(1)²6 = 2 units.
Therefore, changing the height to half of its original value and changing the radius to half of its original value does not have the same effect on the volume. Halving the height of the cone halves the volume, while halving the radius of the cone results in 1/4 the volume.

How many solutions does the following system of equations have?
2y= 5x+4
y= 3x+2
Α. Two
B. One
C. Zero
D. Infinitely many
Answer:
B. One
Step-by-step explanation:
The lines have different slopes, so they must intersect at exactly one point.
There is One solution to this system.
_____
If you solve the first equation for y, you get ...
y = (5/2)x +2
This has a different slope (x-coefficient) than the second equation does, but it has the same y-intercept. That y-intercept is the point of intersection of the lines, hence the solution: (x, y) = (0, 2).

Is 7 a factor of 56w - 7?
Answer:
yes it is
Step-by-step explanation:
Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. ... The prime factors of a number or an algebraic expression are those factors that are prime.
Numbers we can multiply together to get another number.
Example: 2 and 3 are factors of 6, because 2 × 3 = 6
A number can have MANY factors!
Example: What are the factors of 12?
• 3 × 4 = 12, so 3 and 4 are factors of 12
• 2 × 6 = 12, so 2 and 6 are also factors of 12
• and 1 × 12 = 12, so 1 and 12 are factors of 12 as well
So 1, 2, 3, 4, 6 and 12 are all factors of 12
And -1, -2, -3, -4, -6 and -12 also, because multiplying negatives makes a positive.
In Algebra, factors can be expressions like "x+3" etc

Find the product of (6-10i) and it’s conjugate.
Product = ?
FYI: the answer is not 6-10i or 6+10i
Answer:
136
Step-by-step explanation:
(6-10i)(6+10i)
36 +60i - 60i - 100i²
36 - 100i² (i² = -1)
36 + 100
136
Answer: 136
Step-by-step explanation:
First, we need to find the conjugate before we can find the product of the conjugate and 6-10i.
The conjugate is the binomial with an opposite sign.
6+10i
Now that we have our conjugate, we can find the product.
(6-10i)(6+10i) [distribute the factors, FOIL method]
36+60i-60i-100i² [combine like terms]
36-100i² [i²=-1]
36-100(-1) [multiply and subtract]
36+100=136
Our product is 136.

Calculate the sum of the first 50 terms in the sequence.
18, 21, 24, 27, ...
Answer:
hope this is correct
The sum of the first 50 terms in the sequence 18, 21, 24, 27, ... is 4575.
What is the sum of the sequence?The sum of the sequence can be calculated by the formula
[tex]S_n = n/2(2a +(n-1)d)[/tex]
where a is the first term, d is the common difference
To find the sum of the first 50 terms in the sequences: 18, 21, 24, 27, ...
[tex]S_n = n/2(2a +(n-1)d)[/tex]
here, a = 18
d = 21 - 18 = 3
n = 50
[tex]S_{50} = 50/2(2(18) +(50-1)3)\\S_{50} = 25(36+147)\\S_{50} = 4575[/tex]
Thus, the sum of the first 50 terms in the sequence is 4575.

What is an Angle?An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.
An angle is a figure in Plane Geometry generated by two rays or lines that share a common endpoint. The term "angle" is derived from the Latin word "angulus," which meaning "corner".
We have m < AVC = 39
and, m <VCB = 23
Thus, by adding the above angle we get the whole angle AVB.

In circle o, diameter ADB and chord AC are drawn. Find the measure of arc BC. Please help
Answer:
Arc BC is 64°
Step-by-step explanation:
The parameters given are;
∠CAB = 32°
We note that the measure of arc BC = ∠CDB
∠DCA = ∠CAB = 32° (Base angles of an isosceles triangle)
∠ACB = 90° (Angle subtended at the center = Twice angle subtended at the circumference)
∠ACB = ∠DCB + ∠DCA
∴ ∠DCB = ∠ACB - ∠DCA = 90° - 32° = 58°
∠DBC = ∠DCB = 58° (Base angles of an isosceles triangle)
∴ ∠CDB + ∠DBC + ∠DCB = 180° (Sum of interior angles of a triangle)
∠CDB = 180° - (∠DBC + ∠DCB) = 180° - (58° + 58°) = 64°
∠CDB = Arc BC = 64°

b. X = -3 -6 sqrt 3 or -3 + 6 sqrt 3 d. 3 sqrt 3 or -3 + 3 sqrt 3
Answer:
a
Step-by-step explanation:
Given
3(x + 3)² - 81 = 0 ( add 81 to both sides )
3(x + 3)² = 81 ( divide both sides by 3 )
(x + 3)² = 27 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{27}[/tex] = ± 3[tex]\sqrt{3}[/tex] ( subtract 3 from both sides )
x = - 3 ± 3[tex]\sqrt{3}[/tex]

A. They are congruent obtuse triangle
B. They are congruent right triangle
C. They are acute right triangle
D. They are similar right triangle
Answer:
b
Step-by-step explanation:
the triangles are all the same so they are congruent. They are also right triangles so they must be a right triangle the only answer that combine this is b
The green, orange and gray triangles are congruent and right triangles. Thus option B is correct.
What are congruent triangles and right triangle?Two triangles are congruent triangles if they are of same size and shape.
Right triangle is a triangle with one of angle 90°.
The given triangles of green, orange and gray triangles are of same shape and size . Therefore we can say that they are congruent triangles
Also we can see that they all have right angle on the left corner therefore they are right triangles . If they are right triangles then they will be also acute triangles too as the some of other two angles of each triangle will be 90 it means they both are less than 90 and congruent means they are similar too as similar triangles have same shape.
Therefore the most appropriate option is Option B , that given triangles are congruent right triangles.
