y=9+x
Answer:
y = 1x + 9
Step-by-step explanation:
This is probably a form of y = mx + b.
m = the slope of a line, which is up one over one (rise/run)
b = y-intercept, or what point is the line crossing at on the y axis.
This formula is very important and it's very helpful when plotting lines. So remember: y = mx + b !!
Hopefully this helps! Leave a comment wether it does or not. :)
y=mx+b
y=x+9
choose any x coordinates
x = 0,1,2
y is equal to the x coordinate plus 9
in this case y will be
y = 9,10,11
respectively

point p is the midpoint of de dp 6x+4 and de = 14x -10
Answer:
x = 9
Step-by-step explanation:
A midpoint is found by adding up two numbers and then dividing by 2 (Also known as an average). Therefore, a midpoint marks half of a line. That means that DP is 1/2 of DE. We can now form an equation. 6x + 4 = 1/2 * (14x - 10), making 6x + 4 = 7x - 5 by using the distributive property. Next, isolate x by subtracting by 6x on both sides and adding by 5 on both sides. You would get x = 5 + 4, which means that x = 9.

Answer:
g+r=15 and 2.00g+4.50r=37.50 are the two equations you need to use
Step-by-step explanation: IM NOT COMPLETLEY SURE THO
Answer: C
The total number of pounds of trail mix is 15. The pounds of granola added to the pounds raisins has to equal 15. So, one of the equations is g + r=15.
In total the cost of the granola and the cost of the raisins must be equal to $37.50. Since the granola costs $2 per pound and the raisins cost $4.50 per pound, 2g + 4.5r= 37.5.

Step-by-step explanation:
Hope this helps!
Answer:
[tex]7x^3(7x^2-9 )[/tex]
Step-by-step explanation:
To factor, you have to find the GCF of 49 and 63 and the GCF of [tex]x^{5}[/tex] and [tex]x^3[/tex]
Factor 49: 1,7, and 49
Factor 63: 1, 3, 7, 9, 21, 63
Factor [tex]x^{5}[/tex]: [tex]x*x*x*x*x[/tex]
Factor [tex]x^3[/tex]: [tex]x*x*x[/tex]
So the GCF of 49 and 63 is 7
The GCF of [tex]x^{5}[/tex] and [tex]x^{3}[/tex] is [tex]x^3[/tex]
We multiply 7 by [tex]x^{3}[/tex] to get [tex]7x^3[/tex]
So now we start to factor out the GCF of [tex]49x^5-63x^3[/tex]
[tex]7x^3(\frac{49x^5}{7x^3}+ \frac{63x^3}{7x^3} )[/tex]
[tex]\frac{49}{7} =7\\x^5-x^3=x^2[/tex]
[tex]\frac{63}{7} =9\\x^3-x^3=x^0[/tex] because [tex]x^{0}[/tex] can't be written as an exponent we don't write [tex]9x^0[/tex]
When we factor we get [tex]7x^3(7x^2-9 )[/tex]

The diameter of the Sun is 1,391,000 km. The diameter of the Moon is 3,475 km.
The distance from Earth to the Sun is 149,600,000 km.
How far would the Moon have to be from Earth for the Moon to appear the same
size as the Sun?
The similar triangle relationship by the rays of the Sun and the shadow of
the Moon indicates that their distances to Earth are proportional.
The distance the Moon has to be from the Earth to appear the same size as the Sun is approximately 373,731.13 km.Reasons:
The diameter of the Sun = 1,391,000 km
The diameter of the Moon = 3,475 km
The distance between the Earth and the Moon = 149,60,000 km
Required:
The distance that the Moon can be from Earth, such that the Moon appear to be the same size as the Sun.
Solution:
The vertex angle formed by the Moon and the Sun at the Earth are the
same, assuming the Moon and the Sun are in the same line, we have;
Considering the diameters of the Sun and the Moon as parallel lines, we have;
The base angles formed at the Sun and the Moon are equal
Therefore, the shadows of the Sun and the Moon form similar triangles with the Earth.
Using the relationship similar triangles, we have;
[tex]\displaystyle \frac{Disatance \ of \ the \ Sun \ from \ the \ Earth}{Diameter \ of \ the \ Sun} =\mathbf{ \frac{Distance \ of \ the \ Moon \ from \ the \ Earth}{Diameter \ of \ the \ Moon}}[/tex]
Which gives;
[tex]\displaystyle \frac{149,600,000}{1,391,000} = \mathbf{\frac{Distance \ from \ the \ Moon \ to \ the \ Earth, \ d }{3,475}}[/tex]
[tex]\displaystyle The \ distance \ from \ Moon \ to \ Earth, \ d = \displaystyle \frac{149,600,000}{1,391,000} \times 3,475 \approx 373,731.13[/tex]
The distance the Moon have to be from Earth for the Moon to appear the same as the Sun, d ≈ 373,731.13 km.

Answer:
x = 8.8 or x = 44/5
Step-by-step explanation:
1) Multiply both sides of the equation by 4, and cancel out the 4 on the bottom of 3/4, this turns the equation into: 8x - 4 = 3x + 40
2) Move the x to the lefthand side and change the side, do the same for the constant (4), this turns the equation into: 8x - 3x = 40 + 4
3) Combine like terms, subtract 8x from 3x and add 40 to 4: 5x = 44
4) Divide both sides by 5, and your answer is 44/5 (or 8.8 when converted to a decimal)

Which table of values represents the equation Y= 2X +5?
Answer:
The first choice:
x: -5, -4, -3, -2, -1
y: -5, -3, -1, 1, 3
Step-by-step explanation:
If we apply the equation here...
y = 2x + 5
(Let's use -1 for example)
y = 2(-1) + 5 --> y = -2+5, which gives us 3
On the table, it says that the y is 3, so it proves that it is correct
If you apply the equation for all of the x's, it'll give you the y's for the first choice. This doesn't apply to the rest of the tables, so the first table is the correct choice
The values are satisfied by
x y
-5 -5
-4 -3
-3 -1
-2 1
-1 3
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Given:
Y= 2X +5
let us put the value for X
X= 0
Y = 5
and, X=1
Y = 2 + 5 = 7
and, X= 2
Y= 4 + 5 = 9
and, X=3
Y = 6 + 5 = 11
and, X= 5
Y = 10 + 5= 15
and, X= -1
Y= -2 + 5 = 3
Hence, these values are satisfied by

determine the dimensions of the cubes length of the smaller cube is one-third of the length of the larger cube, and the volume of the object is 3250 cubic centimeters
Answer:
44.4 or 14.9 depending on which volume is being stated
Step-by-step explanation:
Not sure if it is the smaller cube or the bigger cube that is 3250 cm^3 so ill do both.
LARGER CUBE IS 3250 cm^3
first find the side length by finding the cube root of 3250, which is about 14.8, then divide that by 3 to find the side length of the smaller cube, which is about 4.9.
SMALLER CUBE IS 3250 cm^3
first find the side length by finding the cube root of 3250, which is about 14.8, then multiply that by 3 to find the side length of the larger cube, which is about 44.4.
An open box will be made by cutting a square from each corner of a 15-inches by 24-inches piece of cardboard and then folding up the sides. What size square should be cut from each corner in order to produce a box of maximum volume
The cut-out from each corner that maximizes the volume is 3 inches.
The dimensions are given as:
[tex]\mathbf{Length = 15}[/tex]
[tex]\mathbf{Width = 24}[/tex]
Assume the cut-out is x.
So, the dimension of the board is:
[tex]\mathbf{Length = 15 - 2x}[/tex]
[tex]\mathbf{Width = 24 - 2x}[/tex]
[tex]\mathbf{Height = x}[/tex]
The volume (V) is calculated as:
[tex]\mathbf{V = Length \times Width \times Height}[/tex]
So, we have:
[tex]\mathbf{V = (15 - 2x) \times (24 - 2x) \times x}[/tex]
Expand
[tex]\mathbf{V = 360x - 78x^2 + 4x^3}[/tex]
Differentiate
[tex]\mathbf{V' = 360 - 156x + 12x^2}[/tex]
Set to 0
[tex]\mathbf{ 360 - 156x + 12x^2 = 0}[/tex]
Divide through by 12
[tex]\mathbf{ 30 - 13x + x^2 = 0}[/tex]
Rewrite as:
[tex]\mathbf{ x^2 - 13x + 30 = 0}[/tex]
Using a calculator, we have:
[tex]\mathbf{x = \{3, 10\}}[/tex]
The value of x = 10 is greater than the dimensions of the box.
So, we have:
[tex]\mathbf{x = 3}[/tex]
Hence, the cut-out from each corner that maximizes the volume is 3 inches.
