Write an equation of the line that passes through the point (6,2) and is perpendicular to the line y=3x+3
Answer:
y = -[tex]\frac{1}{3}[/tex] + 4
Step-by-step explanation:
first of all we know the slope of the equation which is 3x. then we know that we are supposed to write an equation that is perpendicular to y = 3x + 3. so since it is supposed to be perpendicular we have to make the current slope opposite.
so slope for our new equation will be -[tex]\frac{1}{3}[/tex]x.
now since we know our slope we use point-slope form and plug everything in.
point-slope form: y1-y=m(x1-x)
plug it in:
y - 2 = -[tex]\frac{1}{3}[/tex] (x - 6)
= y - 2 = -[tex]\frac{1}{3}[/tex]x +2
= y = -[tex]\frac{1}{3}[/tex] + 4

Y varies directly with x. If y = 21, when x = 7, find y when x = 28.
Answer:

, which can also be written in the form
y

x
when it is directly proportionate and
y

First calculate the Subsets for set, then calculate the number of proper subsets {10,19,5,0}
The subsets of {10, 19, 5, 0} are
{ } - the empty set, or 1 subset of size 0
{10}, {19}, {5}, {0} - 4 subsets of size 1
{10, 19}, {10, 5}, {10, 0}, {19, 5}, {19, 0}, {5, 0} - 6 subsets of size 2
{10, 19, 5}, {10, 19, 0}, {10, 5, 0}, {19, 5, 0} - 4 subsets of size 3
{10, 19, 5, 0} - 1 subset of size 4
A proper subset of a set is any subset of that set that is not equal to that set. The only subset that is not a proper subset is {10, 19, 5, 0}, since that's the set itself. So there are 15 proper subsets.
In general, a set of size n has a total of 2ⁿ subsets, and 2ⁿ - 1 proper subsets.
find the difference -156-(-45)
Answer:
-201
Step-by-step explanation:
a negative minus a negative is like adding, but keeping the same sign.
so we can do 156+45, and we get 201.
now we put the negative sign back.
-201

Sandra transforms a line segment such that the new image is longer than the original line segment. What type of transformation must the line segment have undergone?
A. dilation
B reflection
C rotation
E translation
The type of transformation must the line segment have undergone if Sandra transforms a line segment such that the new image is longer than the original line segment, is dilation, so option A is correct.
What is dilation?The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger.
Given:
Sandra transforms a line segment such that the new image is longer than the original line segment,
The above transformation is an example of dilation, as in dilation the image can be transformed into a large image or a small image,
Thus, the given transformation is an example of dilation.

9. The endpoints of a diameter of a circle are A (2,1) and B(5,5). Find the area of the circle in terms of . (1 point)
25
O
IT square units
O 10 square units
O 255 square units
O 57 square units
Answer:
Area of the circle is 6.25π sq.unit
Step-by-step explanation:
The centre of the circle is at the mid point of a diameter. Th mid point of the diameter is at (5+22,5+12)or(72,3),which is centre. Radius is the distance from end point (5,5)to centre (72,3)∴r=√(5−72)2+(5−3)2=√1.52+4=√6.25=2.5∴
Area of the circle is Ac=π⋅r2=π⋅2.52=6.25π sq.unit[Ans]
The Area of Circle whose endpoints of a diameter of a circle are A (2,1) and B(5,5) is 6.25 sq unit.
What is Distance Formula?If there are two points in the coordinates plane as P(a, b) and Q(c, d) then the distance between these two points are
PQ = √(c- a)² + (d-b)²
We have the endpoints of a diameter of a circle are A (2,1) and B(5,5).
Now, using Distance Formula
d= √{(x2 - x1)² + (y2 - y1)²}
Here, x1 = 2; y1 = 1; x2 = 5; y2 = 5
d = √{(5 - 2)² + (5 - 1)²}
d = √{(3)² + (4)²}
d = √{9 + 16}
d = √25
d = 5 unit
Now, Area of Circle
= πr²
= 3.14 x 2.5 x 2.5
= 6.25π sq units

• Reflect across the y-axis.
Vertically compress by multiplying by : 1/4
9514 1404 393
Answer:
D. J(x) = 1/4(-x)^3
Step-by-step explanation:
Reflection across the y-axis replaces x with -x. Then if Fr(x) represents the reflected function, we have ...
Fr(x) = (-x)^3.
Compression by a factor of c < 1 multiplies the function value by c. Then ...
J(x) = 1/4·Fr(x)
J(x) = (1/4)(-x)^3

The ages of three brothers are consecutive, even integers. If the sum of the first even integer, three times the second even integer and twice the third even integer is fifty. Find the ages of all three brothers
Answer:
The ages of all three brothers are 4,6,8 years.
Step-by-step explanation:
Here n is the smallest of the three consecutive even integers, the condition gives you this equation
2n + 3*(n+2) + (n+4) = 34.
2n + 3n + 6 + n + 4 = 34
6n = 24
n = 4.
Answer. The ages are 4, 6 and 8 years.
Hope this helps you.
The ages of the three brothers are 6, 8, and 10 years, respectively.
How to determine ages of the three brothersLet the ages of the three brothers be \(x\), \(x+2\), and \(x+4\).
The sum of the first even integer, three times the second even integer, and twice the third even integer is fifty:
\[x + 3(x+2) + 2(x+4) = 50\]
Simplify the equation:
\[x + 3x + 6 + 2x + 8 = 50\]
Combine like terms:
\[6x + 14 = 50\]
Subtract 14 from both sides:
\[6x = 36\]
Divide by 6:
\[x = 6\]
So, the ages of the three brothers are 6, 8, and 10 years, respectively.
