The lines represented by the equations 20y-24x=-20y and 5y-6x=-5 are
a) perpendicular
b) the same line
c) neither parallel nor perpendicular
d) parallel
Answer:don’t listen to the other guy he’s wrong. The answer is the same line.
Step-by-step explanation:
20y-24x=-20 add 24x to both sides
20y=24x-20
Divide 20 to all
New equation is
Y=5/6x-1
Now let’s solve for 5y-6x=-5
Add 6x to both sides
5y=6x-5
Divide 5 to all
The new equation is
Y=6/5x-1
As you see they have the same equation so the answer is that the lines are the same :) have a good day guys hope this helped <3

1. 3y - 9
2. 6y - 3
3. 9y- 3
4. 3y - 3
Answer:
3, 9y-3
Step-by-step explanation:
Answer:
3) 9y-3
Step-by-step explanation:
3 (y - 1 + 2y)
3×y - 3×1 + 3×2y
3y - 3 + 6y
rearranging like terms together:
3y + 6y - 3
9y - 3
in math class, the girl to boy i 8 to 6. if there are 24 girl in the class, how many boy are there?
Answer:
[tex]\huge\boxed{\text{18 boys}}[/tex]
Step-by-step explanation:
This is basically just a ratio. If the ratio between the amount of girls to the amount of boys is 8 to 6, then we can create a fraction (girls/boys)
[tex]\frac{8}{6}[/tex]
Using what we know about the second statement (24 girls) we can make a ratio like this (also assuming girls/boys)
[tex]\frac{24}{x}[/tex]
Since the ratios must be equal, we can set them equal to each other.
[tex]\frac{8}{6} = \frac{24}{x}[/tex]
We can cross multiply to find x.
[tex]24 \cdot 6 = 144\\\\144 \div 8 = 18[/tex]
So there are 18 boys.
Hope this helped!

1. There are 12 pieces of fruit in a bowl and 2 of them are

D.

2. Lin's family has completed 30% of a trip. They have traveled
60 miles. How far is the trip? (Hint: You can use a tape diagram,
Highlight the answer that shows how far Lin's family trip is. (2 points)
Answer:
1. D) 17%
2. 200 miles
Step-by-step explanation:
For the first question we can turn the information into a fraction, with the total number of pieces of fruit in the bowl (12) as the denominator and the number of apples (2) as the numerator.
[tex]\frac{2}{12}[/tex]
Then, divide:
2/12 = 0.17 = 17%
For the second question, we set up a proportion. We know that 60 miles corresponds to 30% and the whole distance of the trip, x, corresponds to 100%
[tex]\frac{60}{x} = \frac{30}{100}[/tex]
Cross multiply and solve:
60 * 100 = 30x
6000 = 30x
200 = x

Give two reasons why this shape is a square when x=5.
Answer:
First of all, we can see that this shape have 4 90° angles.
Secondly, since x = 5 we have:
3 × 5 -2 = 15 - 2 = 13 (cm)
And: 5 + 8 = 13 (cm)
=> The two adjacent sides that make up the angle is equal to each other
So this shape is a quare.
=> This shape is a square.

Why does x^4 * x^-4 = 1?
Answer:
Step-by-step explanation:
when you have a negative exponent, you are going to have a fraction. Example: 2^4 * 2^-4= 2^4 is 16 2^-4 is 1/16.
You get the 16 but because it was a negative exponent, the 16 goes on the bottom. 16 as a fraction is 16/1.
When you multiply 16/1 and 1/16. It comes up to 16/16 or 1.
Does this help?
Answer:
below
Step-by-step explanation:
We can use the product rule of exponents to solve [ x^y * x^z = x^y+z ].
x^4 * x^-4 = 1
x^4+(-4) = 1
x^0 = 1
1 = 1

Nick and Michelle are searching for a treasure chest underwater. The straight line distance between them is 100 meters. Given the angles in the diagram, who is closers to the chest and why ?
Answer:
Michelle is closer to the treasure chest.
Step-by-step explanation:
If you didn't know, the smallest angle is opposite the smallest line, and it goes the same way for larger angles.
65 degrees is opposite Michelle's line, making her line shorter.

The measure of <ACD is 120. Find the measure of <ACB, <BCD, and <ACE.
Explain how you found the measure of <ACE.
Answer:
m∠ACB = 39°
m∠BCD = 81°
m∠ACE = 60°
Step-by-step explanation:
From the picture attached,
m∠ACD = 120°
Since, m∠ACD = m∠ACB + m∠BCD
x + (2x + 3) = 120°
3x + 3 = 120
3x = 117
x = 39
Therefore, m∠ACB = 39°
m∠BCD = (2x + 3) = 2(39) + 3
= 81°
Since, m∠ACE + m∠ACB + m∠BCD = 180° [Angles formed at a point on a straight line]
m∠ACE + 39 + 81 = 180
m∠ACE = 180 - 120
m∠ACE = 60°

How do you describe the principal square root of the 34? *
A. The square root of 34 is a rational number.
B. The square root of 34 is an irrational number.
C. The square root of 34 is not defined.
D. The square root of 34 can be a positive or negative number.
Answer:
B. The square root of 34 is an irrational number.
Step-by-step explanation:
The square root of 34 is a rational number if 34 is a perfect square.
Since 34 is not a perfect square, it is an irrational number.
Since the square root of 34 is not a perfect square, hence, the square root of 34 is an irrational number: Option B is correct.
Irrational numbers are numbers that cannot be written as a ratio of two integers.
Examples of irrational numbers are surd functions, euler's number, pi value.Most terminated decimals are also irrational numbers.Since the square root of 34 is not a perfect square, hence, the square root of 34 is an irrational number.
