Answer:

y = [tex]\frac{1}{3}[/tex] x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{1}{3}[/tex] and c = - 2, then

y = [tex]\frac{1}{3}[/tex] x - 2 ← equation of line

Answer:

  A.  40.7%

Step-by-step explanation:

The selling price for a $5 profit will be ...

  $12.75 +5.00 = $17.75

From $29.95, this represents a change of ...

  (17.75 -29.95)/29.95 × 100%

  = -12.20/29.95 × 100% ≈ -40.7346%

Answer:

y = -½x + 7

Step-by-step explanation:

Perpendicular lines have the product of their gradients equal to -1

For this to be true, since the first gradient is 2, the second gradient must be -½

So the first part is

y = -½x + c

We substitute our point to get c

5 = -½(4) + c

7 = c

Our line is

y = -½x + 7

FYI slope-intercept form is y = mx + c

Answer:

9[tex]\pi[/tex]

Step-by-step explanation:

The reason why that is wrong is because it says in terms o pi which means you do NOT multiply pi by the radius squared.

EQUATION FOR AREA OF A CIRCLE: [tex]\pi r^{2}[/tex]

When you put it all together you get: [tex]\pi * 3^{2}[/tex] which equals [tex]9\pi[/tex]

DO NOT MULTIPLY 9 AND PI. IT'S JUST 9[tex]\pi[/tex]

Answer:

Step-by-step explanation:

What I did is I used ratio.

20:12

15:X

Cross multiply:15x12

Answer:180

The answer you get divided by 20.

180/20=9.

Answer:

B

Step-by-step explanation:

Given y varies directly as x, then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when x = 20, y = 12, then

12 = 20k ( divide both sides by 20 )

k = [tex]\frac{12}{20}[/tex] = [tex]\frac{3}{5}[/tex]

y = [tex]\frac{3}{5}[/tex] x ← equation of variation

When x = 15, then

y = [tex]\frac{3}{5}[/tex] × 15 = 9

Answer:

B

Step-by-step explanation:

ok so since the two pieces added together just be 96 inches, we know that

x+y=96

that already eliminates everything but B.

let's keep going though.

let's have y be the piece that is 6 inches longer than double the length of the other piece.

y=2x+6

Answer:

5.33 unit

Step-by-step explanation:

logically FA = EA - EF = 13.33-8 = 5.33 units

Since, E, F and A all lie on the same line EA . The information ED=  units is redundant. Therefore we can say that FA= 5.33 unit

The length of FA is 5.33 units

The given parameters are:

[tex]\mathbf{EF = 8}[/tex]

[tex]\mathbf{ED = 10}[/tex]

[tex]\mathbf{EA = 13.33}[/tex]

EF and EA implies that point E is between line FA

So, the length of FA is calculated using:

[tex]\mathbf{FA = EA - EF}[/tex]

Substitute known values

[tex]\mathbf{FA = 13.33 - 8}[/tex]

Subtract

[tex]\mathbf{FA = 5.33}[/tex]

Hence, the length of FA is 5.33 units

Answer:

The answer is y=-x+4 and y=-3x+2

Step-by-step explanation:

Answer:

y = x + 4 and y = 3x + 2

Step-by-step explanation:

Both of the lines slopes are positive, and for the equation of y = 3x + 2, the slope is 3 rather than [tex]\frac{1}{3}[/tex] because it goes up 3 then to the right 1 rather than up 1 and to the right 3.

[tex]G(0, -\dfrac{2}{3})[/tex]

Step-by-step explanation:

Given that:

The coordinates of the vertices of a triangle [tex]\triangle PQR[/tex] are given as:

[tex]P(-4, -1)[/tex], [tex]Q(2, 2)[/tex], and [tex]R(2, - 3)[/tex].

To find:

The coordinates of the centroid of the triangle.

Solution:

The coordinates of the centroid of a triangle is given as:

[tex]G(\dfrac{x_1+x_2+x_3}{3}, \dfrac{y_1+y_2+y_3}{3})[/tex]

Where [tex](x_1,y_1), (x_2,y_2)\ and\ (x_3,y_3)[/tex] are the coordinates of the vertices of the triangle.

As per the given values, we have:

[tex]x_1 = -4\\y_1 = -1\\x_2 = 2\\y_2 = 2\\x_3 = 2\\y_3 = -3[/tex]

Putting the values,we can find the coordinates of centroid as:

[tex]G(\dfrac{-4+2+2}{3}, \dfrac{-1+2-3}{3})\\\Rightarrow G(0, -\dfrac{2}{3})[/tex]

Therefore, the coordinates of the centroid is:

[tex]G(0, -\dfrac{2}{3})[/tex]

Answer:

So answer is [tex]\frac{10+x}{y-3}[/tex]

Step-by-step explanation:

We are given with quotient of 10 plus x and y minus 3.

So, we can write 10 plus x as 10+x and y-3

So, quotient of 10+x and y-3 is [tex]\frac{10+x}{y-3}[/tex]

Answer:

Yes.

Step-by-step explanation:

Yes.

y = 4x - 9 is the equation of a line with slope 4and y-intercept -9.

All non-vertical lines are functions.

Since a line with slope 4 is not a vertical line, this relation is a function.

Answer:

2.2

Step-by-step explanation:

46/21 rounded to nearest tenth place is zero.

Rounding nos. to nearest places have an advantage that is we could remember the number easily.

For example - 16534 rounded to ten thousand's place is 20000 which is more easier for us to remember and also the number rounded to a certain place retains it's value to about that place.

According to the given question we have to convert the fraction 46/21 as a decimal rounded to the nearest tenth.

We know,

46/21 is

= 2.2 approximately .

Now, if we round 2.2 to the nearest tenth, 2.2 can be written as 02.2.

We observe that it's tenth digit is 0 so when we round it to the nearest tenth place it will be 0.

Answer:

The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50

Step-by-step explanation:

Let,

x be the price per pound of walnuts

y be the price per pound of chocolate chips

According to given statement,

4x+8y=25     Eqn 1

2x+3y=10      Eqn 2

Multiplying Eqn 2 by 2

2(2x+3y=10)

4x+6y=20    Eqn 3

Subtracting Eqn 3 from Eqn 1

(4x+8y)-(4x+6y)=25-20

4x+8y-4x-6y=5

2y=5

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{5}{2}\\y=2.50[/tex]

Putting y=2.50 in Eqn 2

2x+3(2.50)=10

2x+7.50=10

2x=10-7.50

2x=2.50

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{2.50}{2}\\x=1.25[/tex]

Hence,

The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50
