Is an imaginary "line" from the Earth to the Moon a line, a ray, or a segment? and WHY?
Answer:
Segment
Step-by-step explanation:
It is a segment because it has two endpoints (the Earth and Moon). If it was a ray, it would go on forever in one direction. It doesn't, so the imaginary line is a segment.
The first image is a segment, the second is a ray.
Hope this helps. :)
Answer:
Segment
Step-by-step explanation:
A ray goes on forever a segment has end points

what ordered pair would describe each intersection?
y=8-X and y=5X-40
Answer:
(8, 0 )
Step-by-step explanation:
Given the 2 equations
y = 8 - x → (1)
y = 5x - 40 → (2)
Substitute y = 5x - 40 into (1)
5x - 40 = 8 - x ( add x to both sides )
6x - 40 = 8 ( add 8 to both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (1)
y = 8 - 8 = 0
Solution is (8, 0 )

The value of y varies directly with x. When y= 2 4/7, x= 37 .
What is the value of y when x is 27 ?
1 5/7
2 3/7
3 1/7
3 4/7
Answer:
Option (a).
Step-by-step explanation:
The value of y varies directly with x. It would mean that,
y=kx, where k is constant
When
[tex]y=2\dfrac{4}{7},x=\dfrac{3}{7}\\\\y=\dfrac{18}{7}, x = \dfrac{3}{7}[/tex]
then,
[tex]\dfrac{18}{7}=k\times \dfrac{3}{7}\\\\k=6[/tex]
When x = 27,
[tex]y=6\times \dfrac{2}{7}\\\\y=\dfrac{12}{7}\\\\\text{or}\\\\y=1\dfrac{5}{7}[/tex]
So, the value of y is [tex]1\dfrac{5}{7}[/tex] when x is 27.

ax +3= 6
Solve for x.
Answer:
Step-by-step explanation:
Let's solve for a.
ax+3=6
Step 1: Add -3 to both sides.
ax+3+−3=6+−3
ax=3
Step 2: Divide both sides by x.
ax /x = 3 /x
a= 3 /x
Answer:
a= 3 /x
Answer:
ax = 3
Step-by-step explanation:
ax + 3 = 6
Subtract 3 from both sides of the equation
ax = 3

A kilogram of potatoes cost $25.A dozen bananas cost $40.
a) Write an algebraic expression for the total cost of n kilograms of potatoes and one dozen bananas.
b) Evaluate your expression to determine the cost of 15kg of potatoes and one dozen bananas
Answer:
a) T = 25n + 40
b) T = $415
Step-by-step explanation:
The total cost of 'n' kilograms of something can be expressed as 'n' multiplied by the cost, since it is a constant cost per unit. Therefore the price for n kg of potatoes can be expressed as 25n. We are also told that a dozen bananas cost $40, so our expression is the cost of potatoes added to the cost of bananas. So, is we use 'T' for total cost, our expression will look like this:
T = 25n + 40
Now we can use this expression to find the cost of 15kg of potatoes and the same amount of bananas. We can do this by simply substituting the given amount for n:
T = 25(15) + 40
T = 375 + 40
T = $415
The cost of 15kg of potatoes and one dozen bananas is $415.

Here are three lamps.
lamp C
lamp B
lamp A
Lamp A flashes every 20 seconds.
Lamp B flashes every 45 seconds.
Lamp C flashes every 120 seconds.
The three lamps start flashing at the same time.
How many times in one hour will the three lamps flash at the same time?
Answer with step-by-step explanation:
First of all, we need to calculate how many times the 3 lamps flash in a minute. We can do this by finding their LCM (least common multiple), which is 360. 360 is equivalent to 6 minutes, so that is going to be our test time. Lamp a flashes every 20 seconds, so 360/20 = 18 flashes. Then, 360/45 = 8 flashes. Finally, 360/120 = 3 flashes. 18 + 8 + 3 = 29 flashes per 6 minutes. If so, we multiply 29 by 10, because 60 minutes per hour ÷ 6 minutes = 10. So 29 × 10 = 290 flashes per hour

How can you tell by just looking at the coefficients of -2x² and 2x2 that the terms will add to zero?
Answer:
Their coefficient have the same number but with opposite sign
Step-by-step explanation:
We can tell that the two coefficient will add to zero because they have the same value but opposite signs.
When two numbers are of the same value but with opposite sign, they add up to zero.
The given numbers are;
-2x² and 2x²
Coefficient is the number before the variable. Here, the variable is x,
-2x² = -2
2x² = 2
-2 + 2 = 0
Solve for x.

=> 4x + 13x = 112+7
=> 17x = 119

=> x = 7

Step-by-step explanation:
The vertices of a figure are FC -9,- 9),G-3, -6),H(-3,-9). Find the coordinates of the image after a dilation with a scale factor of 2 3 and then a translation 6 units up.
Transformation involves changing the size and position of a figure.
The new coordinates of the figure is:
[tex]\mathbf{F" = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,0)}[/tex]
The coordinates are given as:
[tex]\mathbf{F = (-9,-9)}[/tex]
[tex]\mathbf{G = (3,-6)}[/tex]
[tex]\mathbf{H = (-3,-9)}[/tex]
When the figure is dilated by 2/3, the new coordinates are:'
[tex]\mathbf{F' =\frac 23 \times (-9,-9) = (-6,-6)}[/tex]
[tex]\mathbf{G' =\frac 23 \times (3,-6) = (2,-4)}[/tex]
[tex]\mathbf{H' =\frac 23 \times (-3,-9) = (-2,-6)}[/tex]
When the figure is further translated up by 6 units, the new coordinates are:
[tex]\mathbf{F" = (-6,-6 + 6) = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,-4 + 6) = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,-6 + 6) = (-2,0)}[/tex]
Hence, the new coordinates are:
[tex]\mathbf{F" = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,0)}[/tex]
