Explanation:
Compare each equation to the form y = mx+b
m = slope
The first equation has slope -1/3 and the second equation has slope 1/3
The slopes do not multiply to -1, so the lines aren't perpendicular.
The slopes aren't equal, so the line aren't parallel either.

Tasha believes that she can rewrite the difference 120 − 84 as a product of the GCF of the two numbers and another difference. Is she correct? Complete the explanation. She is not correct. The GCF of 120 and 84 is 12 . So 120 − 84 can be written as 12 × 10 − × , which is × (10 − ) or × = .
Step-by-step explanation:
GCF is greatest common factor. It is also termed as HCF.
Firstly we write the factors of 120 and 84
120 = 2×2×3×5×2
84 = 2×2×3×7
HCF of 120 and 84 = 12
ATQ,
Tasha believes that she can rewrite the difference 120 − 84 as a product of the GCF of the two numbers and another difference. Let's try to write like this.
120-84 = (12×10-12×7) [using the distributive property]
= 12(10-7)
It means that the difference 120 − 84 as a product of the GCF (i.e. 12) of the two numbers and another difference (i.e. 10-7). Hence, she is correct.

“The 8th term of the sequence 781250, 156250, 31250…….is 10”
True or false ? HELPP PLS ITS DUE IN 27 MINS
This will take roughly 3 minutes,
First i'm assuming this is an arithmetic sequence since using the recurring formula;
156250=781250+d
where d is the common difference
d=-625000
Using the implicit relation we can then say;
u(N)=u⁰+nd
where are looking for u⁷ since our first term is u⁰, second is u¹....8th is u⁷
u(7)=781250-6250000
u(7)=-5868170
No it's not 10 if this is arithmetic sequence.
If this sequence is geometric then,
r=156250/781250
r=1/5
So we're diving by 5
we can use the implicit relation which states:
u(n)=u⁰r^n
u(7)=781250×1/5^7
u(7)=10
THIS IS A GEOMETRIC SEQUENCE AND THE 8TH TERM IS 10 SO THIS THIS TRUE HURYY

Pls helpppp on this question
Answer: Part A - C, Part B - 12 pieces
Step-by-step explanation:
Part A:
We know that 1/4 of Meredith's sub is bigger than 1/4 of Jim's sub, so we can set up an inequality.
Let Meredith's sub size = m; Jim's = j
Therefore, 1/4*m > 1/4*j
We can multiply both sides by 4:
m > j
Thus, the correct answer is C
Part B:
Since he had 1/4 of it left, that means he at 1 - 1/4 of it = 3/4 of his sub.
We can calculate the value of 3/4 * 16 = 12 pieces

How many solutions does this system have?
X + 2y = 0
10y = -5x
Choose the correct answer below.
No solution
O Exactly one solution
O Infinitely many solutions
Click to select your answer.
Answer:
Infinitely many solutions
Step-by-step explanation:
Given the system:
[tex]\left \{ {{x+2y=0} \atop {10y=-5x}} \right.[/tex]
One way to do it is to use substitution. That means we want to isolate one of the variables in one equation so we can plug it into the other equation. We can isolate [tex]x[/tex] in the first equation by subtracting [tex]2y[/tex] from both sides.
[tex]\left \{ {{x=-2y} \atop {10y=-5x}} \right.[/tex]
Now we know what [tex]x[/tex] is, so we can plug it into the bottom equation.
[tex]10y=-5(-2y)[/tex]
Then we simplify the right side:
[tex]10y=10y[/tex]
Then we divide both sides by 10:
[tex]y=y[/tex]
Since [tex]y[/tex] will ALWAYS be equivalent to itself, no matter what, we know that there are infinitely many solutions.

A.)Ro, 27040 T-2, o(x,y)
B.)T-2,0° Ro, 2700(x, y)
C.)Ro, 270w Ory-|(x, y)
D.) ry-axisº Ro, 270w(x, y)
A notation that correctly describes the given transformation is:
[tex]R_{O, 90\°}, r_{x-axis}[/tex]
A rotation of 90° around the origin, followed by a reflection over the x-axis.
How to describe the transformation?
Here you can see that we have a rectangle in the first quadrant, and then it is moved to the third quadrant.
In the image, you can also see that the orientation of the rectangle changes, thus, we have a type of rotation.
A rotation from the first quadrant to the second quadrant would give use the desired orientation of the rectangle, and then we could reflect it over the x-axis to reach the third quadrant, so we can write the transformation as a rotation over the origin of 90° followed by a reflection over the x-axis.
I'm not sure of the notation you use in the options, but this would be written as:
[tex]R_{O, 90\°}, r_{x-axis}[/tex]
That is a rotation of 90° around the origin followed by a reflection over the x-axis.

Answer:
x = 10 , EF = 8 , FG = 15.
Step-by-step explanation:
Given : If EF = 2x – 12, FG = 3x – 15, and EG = 23.
To find : find the values of x, EF, and FG.
Solution : We have given EF = 2x – 12, FG = 3x – 15, and EG = 23.
Let the line E ___F___G.
Here F is the mid point of EG . ( mid point divide the line EG cut the line EG in two equal parts)
We can say EF = FG.
EF + FG = EG -------(1)
Plug tha values EF = 2x -12 and FG = 3x - 15 , EG = 23 in equation (1).
2x - 12 + 3x -15 = 23 .
On combine like terms
2x + 3x -12 -15 = 23 .
5x - 27 + 23 .
on adding both side by 27.
5x = 23 +27.
5x = 50 .
On dividing both sides by 5.
x = 10.
Them, EF = 2 (10) -12
20 -12
EF = 8
FG = 3 (10) -15 .
FG = 30 -15 .
FG = 15.
EG = 5 +18 = 23 .
Therefore, x = 10 , EF = 8 , FG = 15.

In the morning, Jasmine biked to her grandma's house in 45 minutes. When she was biking back home in the evening it was foggy and she went 4 mph slower. The trip back took her 1 hour and 10 minutes. How far from her house does her grandmother live?
Answer:
8.4
Step-by-step explanation
Jasmine's grandma's home will be 504 miles away from her home
What is the relation between distance[x] and time[t]?The relation between distance[x] and time [t] is -
[x] = v [t]
where v is the velocity of body.
Given is Jasmine reached her grandma's house in 45 minutes. When she was biking back home in the evening it was foggy and she went 4 mph slower. The trip back took her 1 hour and 10 minutes.
Let her grandma's home be [x] miles away form her house.
Assume that her velocity was [v] mph on her way to grandma's house.
45 = x/v
x = 45v
Her velocity on her way back home would be [v - 4] mph
70 = x/(v - 4)
x = 70(v - 4)
Equating both -
45v = 70(v - 4)
45v = 70v - 280
70v - 45v = 280
25v = 280
v = 11.2 mph
The value of [x] will be -
x = 45 x 11.2 = 504 miles
Therefore, Jasmine's grandma's home will be 504 miles away from her home

Heather and Amanda each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same storm. Heather spent $50 on 2 rose bushes and 3 geraniums. Amanda spent $186 on y rose bushes and 12 geraniums. What is the cost of one bush and one geranium?
Answer:
one Bush costs $19 and one geranium costs $6
Step-by-step explanation:
Let the cost of one Bush be x
Let the cost of one geranium be y
If Heather spent $50 on 2 rose bushes and 3 geraniums, then the equation that represent the statement is:
2x+3y = 50….... 1
If amanda spent $186 on 6 rose bushes and 12 geraniums, then the equation representation will be:
6x+12y = 186…......2
Solve equations 1 and 2 simultaneously
2x+3y = 56..... 1 × 3
6x+12y = 186 ..... 2 × 1
.......…............
6x+9y = 168
6x+12y = 186
Subtract
9y - 12y = 168-186
-3y = -18
y = -18/-3
y = 6
Substitute y = 6 into equation 1:
2x+3y = 56
2x+3(6) = 56
2x+18 = 56
2x = 56-18
2x = 38
x = 38/2
x = 19
Hence one Bush costs $19 and one geranium costs $6
NB: note that the y rose bushes in the question was corrected and 6 rose bushes was used instead in the equation.
