The given system has zero solutions.
Lines that never cross one other are said to be parallel. Hence, a pair of parallel lines must have the same slope but distinct intercepts. (On the other hand, identical lines have same intercept).
In the general equation of a line, y = mx + b, m represents the slope of the line.
The general equations of parallel lines would be of the form:
(1) y = mx + b
(2) y = mx + c
where b and c are any constants.
Now, we observe that the given equations are of the above form with m=2, b=2 and c=0, therefore, they are parallel lines. Since, parallel lines never intersect each other, they have no solution.

Use the polygon tool to graph the dilated figure.
Answer: (3, 3), (3, 9), (-6, 9), (-6, 3)
Step-by-step explanation:
With a dilation of 3 centered about the origin-
the point (1, 1) would go to (3, 3)
the point (1, 3) would go to (3, 9)
the point (-2, 3) would go to (-6, 9)
the point (-2, 1) would go to (-6, 3)
simply multiply the original coordinates all by 3.
"divide 9 by p, then multiply 2 by the result" i need the expression for this, thank you
Answer: The expression would look like this p/9 (2)

Why is adding two fractions different from multiplying the two fractions?
Answer:
Step-by-step: The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater. This is especially useful when you are working with larger fractions that you aren't sure how to reduce.
Answer:
adding two fractions is different than multiplying two fractions bc after adding the fractions, you have to simplify them and it is not easy but with multiplying, you multiply from left to right.

Cameron said that the y-intercept of a quadratic function always tells the maximum value of that function.
Explain Cameron's error.
The y-intercept is where the graph crosses the y-axis and is not necessarily where the maximum is. For instance, consider the graph of [tex]y=x^2 +2x+4[/tex].
if log4^u - log8^v =1 find u in terms of v
u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹
We are given that:
log 4 ^ u - log 8 ^ v = 1
This can also be written in another way using the logarithm properties. We get that:
u log 4 - v log 8 = 1
Subtract v log 8 from both the sides:
u log 4 = 1 + v log 8
v log 8 = u log 4 - 1
v = ( u log 4 - 1 ) / log 8
v = u log (- 4 ) - ( log 8) ⁻¹
Therefore, we get that, u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹

Write a slope-intercept equation for a line passing through the point (4,7) that is parallel to y=x+1. Then write a
second equation for a line passing through the given point that is perpendicular to the given line.
Answer:
y = x + 3
y = -x + 11
Step-by-step explanation:
When the slopes are parallel they are the same. When slopes are negative, the slope is the negative reciprocal.
Parallel: The slope is 1. This is the coefficient of the x in the equation given. If you do not see a number before the x like in y = x + 1, then number is 1.
Use this form:
y =mx + b Us the slope of 1 to put in for m. Use 4 for x and 7 for y
7 =(1)4 + b Solve for b.
7 = 4 + b Subtract 4 from both sides.
3 = b
The equation for the parallel line is
y = x + 3.
Perpendicular:
y = mx + b This time the slope is -1 Still use 4 for x and 7 for y
7 = (-1)4 + b
7 =-4 + b add 4 to both sides
11 = b
The equation would be y = -x + 11

Answer the question.
The distance from the Earth to the Sun is about 1.5 x 108 km, while the distance from the Earth to the
moon is about 3.8 x 105 km. If a scale model of the solar system is constructed so that the distance
from the Earth to the Sun is 100 meters, what will be the distance from the Earth to the moon?
Select one:
O a. 39, 474 m
O b.
39.5 m
O c. 6.36 m
O d. 0.25 m
The distance from the Earth to the moon, in the scale model, is d. 0.25 m
As per the known fact, ratio of measurement in real is equal to the ratio of measurement on scale. Further, ratio will be calculated in this case as -
Distance from Earth to Sun in real : Distance from Earth to Moon in real = Distance from Earth to Sun on scale : Distance from Earth to Moon on scale
Keep the values in mentioned relation to find the distance from Earth to Moon.
1.5×10⁸:3.8×10⁵ = 100:distance from Earth to Moon on scale
Distance from Earth to Moon on scale = 100×3.8×10⁵/1.5×10⁸
Distance from Earth to Moon on scale = 0.25 m
Therefore, the correct option for distance is d. 0.25 m.
