Answer:
The slope of the line segment CD = 9
Hence, option 'D' is true.
Step-by-step explanation:
Given that the slope of line segment = 9
We know that two triangles would be similar if their corresponding angles are congruent and the corresponding sides are in proportion.Given that the line segments AB and CD are both parts of the same non-vertical line. It means their slopes must be the same.
Thus, the slope of the line segment CD = 9
Hence, option 'D' is true.

What is 2/19 as a percentage?
Give your answer rounded to one decimal place.
Answers
Answer:
10.53%
Step-by-step explanation:
The first step is to divide 2 by 19 to get the answer in decimal form: 2 / 19 = 0.1053 Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.1053 * 100 = 10.53%
Answer:
11%
Step-by-step explanation:
Divide 2 by 19 and then move the decimal place twice to the right. It should be 10.5 but if rounded it becomes 11 so 11%

Answer:
Multiply the second equation by -3 to get -3x - 9y = -30.
Step-by-step explanation:
When eliminating, you need to find a term with the negative of that term to combine so that they cancel each other out. An example would be 3x in the first equation and (-3x) in another equation so that when added, it becomes: 3x-3x = 0.
In the second equation, you see that there is already an x there and you just need to make it become (-3x). Thus, you multiply the entire second equation by -3 to make -3x. Once you have done that, you can combine the two equations and eliminate 3x from the first equation.
3x + 5y = 30
-3x - 9y = -30
3x + 5y -3x - 9y = 30 + (-30)
0 - 4y = 30 - 30
-4y = 0
You can find y and then x later on from here.

Answer:
y = -2x
Step-by-step explanation
slope intercept form: y = mx + b
m is slope and b is y-intercept
1. lets find y-intercept cuz thats easiest
the line crosses (0,0) at the y-axis so there is no y-intercept
2. to find slope rise/run
we'll start at (0,0) since that's the y-intercept
3. slope is rise/run = -2/1 = -2
it's negative becuase it's going left
_____________________________________________________
another way you can find slope is by the equation y2 - y1/ x2 - x1
take 2 random points from the line, i will use (0,0) and (-2,4)
4 - 0/ -2 - 0 = 4/-2 = -2
slope is -2
It is estimated that there are 1.2×1057 atoms in the Sun. The number of atoms in the rest of the Solar System is approximately 1.2×1056. About how many more atoms exist in the Sun than in the rest of the Solar System? Drag numbers to complete the answer in scientific notation.
Answers
Answer:
1.08 * 10^57
Step-by-step explanation:
Given that:
Number of atoms in the sun = 1.2 * 10^57
Number of atoms in the rest of the solar system = 1.2 * 10^56
About how many more atoms exist in the Sun than in the rest of the Solar System?
Subtract the number of atoms in solar system from number of atoms in sun
(Number of atoms in sun - number of atoms in rest of the solar system)
(1.2 * 10^57) - (1.2 * 10^56)
= 1.08 * 10^57 (using calculator)

AB (A to B) is twice BC ( B to C )
AB is 2 - x. BC is x - (-4)= x + 4
So
2-x=2 (x + 4)

3x = -6
x = -2

(Same logic as above)
AB is -5 -y. BC is u - 7

Answer:
(a), (b), (c) are non-proportional
(d) is proportional
Step-by-step explanation:
An equation or graph with a non-zero y-intercept is non-proportional. That is true for (a), (b), (c).
The table of (d) is proportional, with a constant of proportionality of 6.5.

Comment on (c)
In a proportional relation, price would go up with quantity, not down. If the prices both end in 9, one cannot be double the other, as would be required for the price of a gallon to be proportional to the price of a half-gallon.

Answer:
m = 2
Step-by-step explanation:
The given equation is :
8x – 4y - 9 = 0
The general equation of a line is given by :
y = mx+b ...(1)
here m is slope and b is y-intercept
Equation (1) can be written as :
8x – 4y = 9
Dividing both sides by (-4)
[tex]\dfrac{8x}{-4}-\dfrac{4y}{-4}=\dfrac{9}{-4}\\\\-2x+y=-\dfrac{9}{4}\\\\y=2x+\dfrac{-9}{4}[/tex] ...(2)
Comparing equation (1) and (2), we get :
m = 2
Hence, the slope of the line is 2.

Answers
Answer:
(2 n)/3-2/3 = n/6+4/3
(2 n)/3-2/3 = (2 n-2)/3:
(2 n-2)/3 = n/6+4/3
Put each term in n/6+4/3 over the common denominator 6: n/6+4/3 = n/6+8/6:
(2 n-2)/3 = n/6+8/6
n/6+8/6 = (n+8)/6:
(2 n-2)/3 = (n+8)/6
Multiply both sides by 6:
(6 (2 n-2))/3 = (6 (n+8))/6
6/3 = (3×2)/3 = 2:
2 (2 n-2) = (6 (n+8))/6
(6 (n+8))/6 = 6/6×(n+8) = n+8:
2 (2 n-2) = n+8
Expand out terms of the left hand side:
4 n-4 = n+8
Subtract n from both sides:
(4 n-n)-4 = (n-n)+8
4 n-n = 3 n:
3 n-4 = (n-n)+8
n-n = 0:
3 n-4 = 8
Add 4 to both sides:
3 n+(4-4) = 8+4
4-4 = 0:
3 n = 8+4
8+4 = 12:
3 n = 12
Divide both sides of 3 n = 12 by 3:
(3 n)/3 = 12/3
3/3 = 1:
n = 12/3
The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

Answer:
hope ithelps :)
Step-by-step explanation:
1) x=3 is a vertical line, so if you are looking for a line that is perpendicular you are looking for a horizontal line.
And horizontal lines go through the y-axis and have equations of y= a #
2)the point on the vertical line is (4,-5), it has a y-value of -5
****Every y value on a horizontal line will be the same
so the equation for a perpendicular line would be y= -5
