Step-by-step explanation:
For two lines to be parallel they must have the same slope that is,M1=M2
For two lines to be perpendicular the slope of one must be the negative reciprocal of the other
Let's first find the slope of all three lines.
For line 1
6x-6=10y
2/5x-2/5=y
slope=2/5
For like 2
slope=5/3
For line 3
y=5/3x+2/3
We can therefore say that:
line 1 and line2 are neither parallel nor perpendicular
line 1 and line 3:
neither parallel nor perpendicular
line 2and line 3:
parallel lines

Hey there!
Yes, it does. It rounds to 1.4.
1.414213562 rounded to the nearest tenth is 1.4, since the next number is less than 5, the 4 stays the same. If the next number was a 5 or greater, it would be 1.5, instead of 1.4.

the equation for simple interest is I= p r t (I=interest, p=principal, r=rate, t=time) Find the simple interest paid to the nearest cent for a loan of $1750 at 12% for 18 months (1.5 years).
Answers
Answer:
Simple Interest = $315
Step-by-step explanation:
The formula for Simple Interest
I = P× R × T
I=interest, p=principal, r=rate, t=time
P = $1750
R = 12% = 0.12
T = 1.5 years
I = $1750 × 0.12 × 1.5
I = $315
*The length of the congruent sides of an isosceles triangle is 17cm. If the base of the triangle is 16 cm, find the length of the median.*
1️⃣ 18 cm
2️⃣ 8 cm
3️⃣ 15 cm
4️⃣ 8.5 cm
Answers
Answer:
The median is 15cm.
Step-by-step explanation:
Given that the The length of the congruent sides of an isosceles triangle is 17cm . the base of the triangle is 16 cm . And we need to find the median .
We know that in a isosceles triangle
All perpendicular bisector , altitude and median concide with each other.This means that the base will be divided into two equal parts For Figure refer to attachment .
Using Pythagoras Theorem :-⇒ BM² + AM² = AB²
⇒ (17cm)² = (8cm)² + AM²
⇒ 289 cm² = 64cm² + AM²
⇒ AM² = 289 cm² - 64 cm²
⇒ AM² = 225 cm²
⇒ AM = √225 cm²
⇒ AM = 15 cm .
Hence the measure of median is 15 cm .calculate the average rate of change of the function y= ½x² - 1 over the interval -2 ≤ x ≤ 0
Answers
Answer: The average rate of change of the function in that interval is r = -1
Step-by-step explanation:
When we have a function f(x), the average rate of change in an interval:
a ≤ x ≤ b
Is calculated as:
[tex]rate = \frac{f(b) - f(a)}{b - a}[/tex]
In this case, the function is:
y = f(x) = (1/2)*x^2 - 1
And the interval is:
-2 ≤ x ≤ 0
Then the rate of change will be:
[tex]rate = \frac{f(0) - f(-2)}{0 -(-2)} = \frac{((1/2)*(0)^2 - 1) -((1/2)(-2)^2 - 1)}{2} = \frac{-2}{2} = -1[/tex]
The average rate of change of that function in that interval is r = -1

HELP ! PROBABILITY !
Easy
Answers
Answer:
The probability is zero
Step-by-step explanation:
Probability
There are 3 white counters and 2 black counters in a bag. One of them is chosen at random.
It's required to calculate the probability that a green counter has been chosen.
The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.
The equation to calculate the probability is:
[tex]P=\frac{f}{n}[/tex]
Where f is the number of favorable cases and n is the total cases.
Since there are no green counters in the bag, it's impossible to choose a green counter, thus f=0 out of n=5 total cases:
[tex]P=\frac{0}{5}[/tex]
P = 0
We have put the cross in the mark 0 on the probability scale below

can someone please help me with this question and show work and steps to this math geometry question?? PLEASE
Answers
2x-8 = x+17
1x-8 = 17
1x = 25
x = 25
in order to find ab, you plug in the x into the expression.
ab = 2x-8
ab = 2(25)-8
ab = 42
do the same for bc:
bc = x + 17
bc = 25 + 17
bc = 42
and for ac, combine the two expressions and plug in the value for x.
ac = ab + bc
ac = 2x-8 + x+17
ac = 2(25)-8 + 25+17
ac = 84

The entry ticket to a local football game costs $10 for an adult and $5 for a child. A group of 100 people paid an entry fee of $710. How many adults and how many children were there in this group?
Answers
Answer: Adults = 58
Children = 42
Step-by-step explanation:
Let adults be denoted as a
Let Children be denoted as c
a + c = 100 ...... i
10a + 5c = 710 ...... ii
Multiply I by 5
Multiply ii by 1
5a + 5c = 500 ...... iii
10a + 5c = 710 ...... iv
Subtract iii from iv
5a = 210
a = 210/5
a = 42
Since a + c = 100
c = 100 - 42 = 58.
Adults = 58
Children = 42

For the function f (x) = 3 (x + 7), find -1().
Answers
Given:
The function is [tex]f(x)=3(x+7)^{\frac{1}{4}}[/tex].
To find:
The function [tex]f^{-1}(x)[/tex].
Solution:
We have,
[tex]f(x)=3(x+7)^{\frac{1}{4}}[/tex]
Substitute f(x)=y.
[tex]y=3(x+7)^{\frac{1}{4}}[/tex]
Interchange x and y.
[tex]x=3(y+7)^{\frac{1}{4}}[/tex]
Divide both sides by 3.
[tex]\dfrac{x}{3}=(y+7)^{\frac{1}{4}}[/tex]
Taking power 4 on both sides.
[tex]\left(\dfrac{x}{3}\right)^4=y+7[/tex]
Subtract 7 from both sides.
[tex]\left(\dfrac{x}{3}\right)^4-7=y[/tex]
[tex]y=\left(\dfrac{x}{3}\right)^4-7[/tex]
Substitute [tex]y=f^{-1}(x)[/tex].
[tex]f^{-1}(x)=\left(\dfrac{x}{3}\right)^4-7[/tex]
Therefore, the correct option is C.
