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.

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

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

x      y

-5    -5

-4    -3

-3    -1

-2     1

-1      3

Answer:

y = -3x + 11

Step-by-step explanation:

To find the equation of the line we would plug in the given info into the point slope equation:

[tex]y-y_{1} =m(x - x_{1} )[/tex]

In this case (x1, y1) is (4, -1) and m is -3:

y - (-1) = -3(x - 4)

We can simplify as follows:

y + 1 = -3x + 12

y = -3x + 11

Step-by-step explanation:

Because 29 ≠ 94, the system is inconsistent. There are no solutions.

The similar triangle relationship by the rays of the Sun and the shadow of

the Moon indicates that their distances to Earth are proportional.

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.

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]

[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]

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)

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
